Hello everybody! I have long I want to write an article about the firmware of bios, but I wanted initially to write it for a computer, but everything is not at hand old so that I could show how to update the old BIOS, through the commands. For this, I decided to demonstrate the BIOS update on the laptop. And on this instruction, you can upgrade absolutely any model!

How to update BIOS on a laptop

First, you need to find a bios file. I will show How to update BIOS on ASUS laptop But again I repeat, it can be done with another company.

We go to the official website of the manufacturer. For example, we write in Yandex Asus and see the official website, go through:

Official site asus

Go to service - support.

Service Asus

Now, you need to know the model of your laptop. It is written either on the front of the laptop.

Laptop model Asus on the front panel

Either on the rear lid:

Laptop model Asus

Or else, it happens hidden under the battery and it needs to be removed.

Laptop model under the battery

To search for drivers and bios on the site there are two options, this is a search for model and a choice by category. We will search by the model in the search. We enter the model and click Search.

Search for models asus

If you entered the correct model, the site will give you it. Go through it.

Laptop model Asus

If you can not find a model on the site, then go to and write the model of the laptop and Support.

Model search in Google

Select support or if the site is in English Support.

Laptop support

Next, drivers and utilities (Drivers).

Drivers and utilities

Choose your operating system.


Open the BIOS tab and swing the latest version.

Bios Asus

Now we need to download the utility.

Bios firmware utility

Also choose the latest version and download.

If you do not see the item with the utility, click another version of Windows from the list, because For example, if there is a utility in Windows 8, then sometimes developers are labored to place it in Windows 8.1. But if you do not find it, do not worry, because In the second way, I will show how to update the BIOS straight in it.

If you have a message when installing the BIOS, a message occurs: Sorry This Program Only Support ASUS Notebook, you need to download and install the driver in the same section. ATKACPI. It can be taken in the Utilities section.

Utilities asus


After that, the utility must be established.

You can update the BIOS in two ways:

  1. From bios
  2. Using the utility

    1. BIOS update with utility

Run the utility. It will give such a message, but do not be afraid if you do everything right, then nothing bad will happen. Click OK.


Choose BIOS. It is desirable a file with firmware, put in the root of the disk.

Choosing bios

The program will give another warning that the battery must be charged, otherwise if the laptop turns off during the firmware, then you will have to either throw the motherboard or search for the programmer.

Battery charge before firmware

After starting the program, information about the current and new bios will appear.

I have the last BIOS. This appears this inscription:

BIOS version

In this case, nothing needs to do. But if there is no such sign, the utility will write that the BIOS is correct and you only need to press the Flash button.


First, the BIOS will be erased.

Erasing bios.

Next will go update.

Bios update

And finally checking correctness.

Check bios

And if the check is successful, the firmware process will be completed.

BIOS updated

All is ready. Now restart the laptop.

2. Updating the firmware, using the BIOS itself

In each bios, there is a utility for its firmware. And if the BIOS utilities did not turn out for your laptop, then it can be updated in it. For this we go to the BIOS. This is usually F2 or F10.

Go to the Advanced tab, but you have this utility can be elsewhere. Also, she is called Start Easy Flash, and you may be called ASUS EZ Flash 2, ASRock Install Flash, Q-Flash Utility, in principle everything is associated with the words BIOS, UPDATE, Flash.


When you find it, press ENTER.

By the way I forgot to say. It is desirable if you record the BIOS file on the USB flash drive, and the USB flash drive is pre-format in the FAT32 file system, because Not all bios understand NFTS. The file in the archive also needs to be removed and put in the root of the flash drive.

Bios Update on Laptop

On the left, choose your media, and select the firmware and press the ENTER to the right.

The utility will ask, do you really want to update the BIOS? Press yes.

Bios update

Bios update will go. After graduation, the laptop either will reboot himself, or it will need to restart.

Bios update

That's all! Knowing this instruction, you can upgrade any laptop!

Helped? Thank the author

Simple BIOS is a firmware, with which the computer can turn on at all. It initializes equipment and many other interesting things, but now it's not about that. If you decide to update the BIOS of your PC, but do not know how it can be done - we'll see now.

A small lyrical retreat: under the BIOS in the article, consider not only and not so much in the past Basic Input Output System, but also the modern substitute in the face of UEFI.

Why update

Lategorized question: And why do you need to update it? The list can be continued for a long time, but here are some of the reasons:

  • support for new processors;
  • an increase in the stability of work;
  • improving compatibility with other equipment (for example, RAM or PCI-E devices);
  • closing "holes" in the protective mechanisms of the CPU (recall the notorious MeltDown and Spectre) or AGESA update for AMD processors;
  • adding new features or opening the necessary menus to bios;
  • error correction.

Some items, however, can work up to the opposite. Of the recent, for example, recall the cutting of microcodes to support the CPU "A" series on AM4 motherboards or support PCI-E 4.0 ibid.

Usually each version of the bios posted on the official website has a description with a list of changes. Not necessarily, this list will be full and exhaustive, but it remains on the conscience of the manufacturer.

How dangerous?

Bios update has always been a fairly risky. DANGER, first of all, turning off the power. There are also problems with the update file itself. As a result, you can get a non-working computer, which only twists fans.

However, if not the boot block (boot sector), most of the manufacturers, in any case, have a large four - asus, asrock, gigabyte and msi - exactly, there are various recovery mechanisms. For example, ASRock and Gigabyte may have two chips with biosomes - main and backup. If the first fee fails, it may start with the backup and carry out the recovery procedure. And asus and MSI at such a case have CrashFree BIOS 3 and Flash Bios Button.

We find out the version

To understand whether your card has new versions of bios, you need to determine which version is currently installed. There is no one way to learn it, but we will list only the simplest.

In Windows, you press the Windows + R keys combination, the "Run" window will appear, then enter the command "MSINFO32" and click "OK". A window will appear, where you can learn it in the "BIOS version" column.

If you drop the built-in capabilities, then this procedure can be carried out using various programs. For example, a free CPU-Z utility. Download the program, run, go to the "Mainboard" tab, the "BIOS" section, item "Version". Here is the search for us.

Where to get

You can download or at least check the availability of a new version of the bios on the official website of the manufacturer's company your motherboard. Consider a sequence of actions for each manufacturer of the "Big Four".


Go to the site. Click on the magnifying glass icon in the upper right corner of the screen.

From above comes out the search string. We introduce there the name of your motherboard. As the site is inserted, it will automatically show you the most suitable options. As soon as you saw the desired model, click on it.

The board is open. At the top of the right select the "Support" section.

In the window that opens, first select "Drivers and Utilities", and then, just below, "BIOS and software".

We will seek a list of available bios with a brief description of the changes.


Open the site. At the top of the right in a small field we enter the name of the board and click "Enter" or on the magnifying glass icon.

In the window that appears, we find the desired model and click "Download".

On the page that appears, they slightly up and select "BIOS".

Before us will appear a table with a list for download.

ASRock offers two bios variants depending on how you will install it - via BIOS or Windows. They differ only in the presence in the second version of files with a firmware program.

By the way, immediately, in the "Update BIOS / How to Update" column, you can find a link to the instructions for the selected update method.


We go to the official website. Click on the magnifying glass in the upper right corner.

In the search string that appears, we enter the name of the desired and press "ENTER".

In the issuance that appeared, we find the desired board and revision model (sequisition in the form of Rev. and numbers) and click either Driver or Utility.

Leafs are slightly down and choose the BIOS subsection.

Here are all versions available for download.


Open the site. Sheets at the bottom and select the "Drivers and Downloads" item.

In the window that opens, also leafs just below and select "Downloads",

... and "motherboards".

In the second column, we put "chipset", in the third choose it, in the fourth right fee. On the right will appear its image. Click "Search".

We immediately find ourselves on the page to download bios.

Algorithm for all manufacturers is almost identical. You can also go for a longer way: go to the Products / Products section, select Motherboards, and how long and hard to search for your filters. But it takes much more time.

And the simplest and fast option is to enter your card name in your favorite search engine. Almost always the first or second string will be a direct link to the page of your MP.

Check each letter in the title, for motherboards Gigabyte, check also revision. This is important not to get a brick after the procedure for several thousand rubles.

For example, MSI X470 Gaming Plus Max and MSI X470 Gaming Plus, from the point of view of versions of bios, different boards and bios they also have different.

How to flash

In today's status, there are two main (!) Options for the update:

  • via BIOS;
  • through Windows.

But first preparatory activities. Before the firmware, you must unpack the archive downloaded from the site to access the update file. If you have any settings in the BIOS, write down or remember them, because after updating, all the settings will be reset to the "default", and the saved profiles can either steal or not applied due to the change of version. And in general, it is extremely desirable to reset the settings before the update procedure.

Update through the built-in functionality of the BIOS itself.

We show the example of the Gigabyte Z370 HD3P and MSI X470 Gaming Plus Max.

To enter the BIOS, in most cases, the Delete key is used.


We enter BIOS.

Click the alt key to see the tips. We are looking for Q-Flash, and run.

In the window that opens, you can update (Update) and save (Save) the current version.

Select the update file. In our case, it is not necessary to have a file on a flash drive, you can flash from another drive installed in the system by selecting it in the drop-down list at the bottom of the screen.

Select the update mode (if you do not know which - select the intact) and wait for messages and reboot.


Copy the bios file on the USB flash drive (must be in FAT32 format). We enter BIOS.

Run the utility for the firmware "M-Flash" with the button in the lower left corner.

After rebooting, the utility menu will appear. If everything is fine, you will see the contents of your USB carrier.

Select the bios file, confirm.

After a while you will receive a successful update notification and the computer will reboot.

Update through a specialized motherboard manufacturer utility, from the operating system (Windows family)

On the example of Gigabyte.

To update from the operating system, Gigabyte has been a pretty simple utility for a long time - @BIOS.

Download from the official site from the "Utilities" section (just under the section with BIOS). Run. On the main page, among other things, we see the version of the already installed bios.

On the second tab, you can update from the Internet.

Select the "Update From File" tab, click "Browse" and choose our downloaded file.

Here, in the top item, it is proposed to run "Face Wizzard" - a utility to change the image that appears when loading.

Update Backup BIOS makes it possible to update the backup chip.

We read the warning and choose "OK".

After a successful update message, you will need to restart the PC.

Through the built-in mechanism, running using a separate button

This is a rare update option. There is such an opportunity on some boards, but it is worth mentioning it.


USB BIOS FlashBack - In the Terminology ASUS - utility to update the BIOS without the need to install the processor, RAM and video card.

The downloaded bios file must be renamed, you can use the Biosrenamer program.

Connect the USB drive to the USB Flashback port (usually white, but it is better to check the instructions for the board).

Press the BIOS Flashback button and hold it for three seconds until the Flashback indicator blinks three times.

When the indicator goes out, the process will be completed.

The ASUS website has two instructions on this topic (1 and 2).


On the company's boards, this feature is called Flash Bios Button and also allows you to produce the firmware process without processor, RAM and video card.

The process is very simple:

  • I rename the downloaded bios in msi.rom (yes, you need to change not only the name, but also the file extension) and throw it on the USB flash drive;
  • Motherboard connect to power supply;
  • Insert a USB drive to port version 2.0 (specify in the manual to the board) and click the Flash Bios Button button;
  • Five seconds began to flash the red LED, which speaks about the firmware process;
  • After some time, the LED will go out - BIOS will flash.

For better clarity, the company has released a small roller on the firmware process.

Motherboard BIOS update - the process is quite simple. Although manufacturers provide several options for this, they do not recommend this without necessity. Since with a freelancer you can turn out to be one on one with a non-working fee. However, there is always a backup option - firmware using a programmer. Therefore, albeit not yourself, but to restore the fee affected by the unsuccessful firmware of the bios can be.

Any modern motherboards installed in personal computers (and stationary and mobile) have a built-in BIOS firmware or a more perfect type of its type - UEFI. Like any software, BIOS and UEFI are improved every year. These firmware are adapted to work with new computer equipment, errors and shortcomings of past versions are corrected in them.

New computers or motherboards go on sale with the latest version of BIOS / UEFI. But what if the update came out after the acquisition of equipment? The solution is simple - update the firmware. Consider how to make it different ways.

Risks to update Bios and UEFI

It is important to understand that BIOS and UEFI are systemic firmware responsible for launching the motherboard. Their primary task includes the initialization of the entire built-in and external equipment connected to it, including RAM, processor, hard drives, video card, power controller, etc. Once the devices are "identified", the BIOS performs them alternately. Then the computer turns on and runs the operating system.


In other words, BIOS and UEFI are responsible for including PC. Incorrectly specified firmware settings, not to mention program errors, can seriously affect the performance of the computer, up to its full failure. Such situations may arise for various reasons, among which and the firmware update. Invalidly selected version of BIOS / UEFI or installer program, instruction retreat, accidental interruption of update, etc. - All this can negatively affect the performance of the motherboard. With serious malfunctions, the BIOS microchip can be reflashing only if there are special equipment in the service center.

Even the position of most manufacturers of motherboard to update BIOS / UEFI is such that they are responsible for any negative consequences arising after the procedure. However, all the necessary software for these purposes is provided by them.

Step 1 - Definition of the current version and manufacturer BIOS / UEFI

First of all, it should be determined which version of the BIOS firmware is installed in the motherboard. You can do this in several ways:

To find out the BIOS version through the Windows system, follow the instructions:

  • Open the "Control Panel", then go to the "System and Security" section.
  • In the central part of the window, find the "Administration" subsection and go to it.
  • A window will open with launch launches of various system programs. Run the application - "System Information".
  • The screen displays a list of different parameters. In the column "Element" find the "BIOS version" item, opposite which the manufacturer and software version will be specified.

BIOS version

To learn the BIOS using a computer boot screen, turn off the computer, and then follow the instructions:

  • Turn on the computer.
  • Wait until the mobile motherboard manufacturer's logo appears on the black screen.
  • If earlier it was necessary to press the "F1" key to start the computer, do not press it.
  • The list of parameters will be displayed on the screen, among which the inscription must be present - "BIOS VERSION", "BIOS Revision", "Release" or similar. Opposite the inscription will give a numeric or alphanumeric value, for example - "0701". This is the BIOS version.
  • If the parameter table quickly disappears from the screen, try immediately after displaying it to press the "Pause / Break" key. If it works, the download of the computer will be interrupted at this stage, and it will be possible to calmly define the BIOS version.

Any BIOS / UEFI has a user interface, where the firmware is configured. In it, you can see the BIOS version:

  • Turn on the computer.
  • Immediately after starting, press the "F2", "Delete" or "F12" key (depends on the motherboard model and the BIOS version).
  • The BIOS user interface starts.
  • Directly on the main page either in one of the interface tabs must be present information about the BIOS version:

BIOS version

There are many programs that allow full information about the computer. These include, for example, AIDA64. To find out with its help version BIOS is very simple:

  • Install and run the program.
  • Go to the "System Board" section, then in the BIOS subsection.
  • In the "BIOS Properties" section, find the "BIOS version" element.
  • Ready.

Save the BIOS data obtained by any of these methods.

Step 2 - Downloading Bios Update

BIOS update can be downloaded on the official website of the microchip or motherboard manufacturer. If the firmware is updated on the laptop, the updates can be obtained on the device manufacturers website. Let us give an example of updating the BIOS on the motherboards of stationary computers:

  • First you need to determine the manufacturer and model of the motherboard.
  • You can do this with the help of the previously mentioned AIDA64 utility.
  • Install and run the program. On the left side of the window, open the "System Board" section, then subdivided with the same name.
  • In the "Properties of the System Board" section opposite the "System Board" element, the model of the motherboard is indicated.
  • Go to the official website of the maternal manufacturer.
  • Enter the model of the motherboard in the search.
  • On the System Board page, open the "Support" section, then "BIOS".
  • At the bottom of the page, references to download the firmware "BIOS" will appear.
  • Download the latest firmware version.

In the case of different manufacturers of motherboards, the BIOS / UEFI firmware download process may differ, but the general principle is the same.


Step 3 - BIOS / UEFI Update

As an example, take the Motherboard made by ASRock. After downloading the firmware:

  • If this archive is to unpack the file in the root directory of the hard disk, flash drives, CD. Requires a local disk or external information carrier to be formatted in FAT32.
  • Turn off the computer, then turn it on and go to the BIOS / UEFI user interface.
  • Right from the BIOS / UEFI interface, you can run the update utility. It is called "Instant Flash". Usually this utility is located in the "Smart" or "Advanced" section.
  • The utility automatically scans the flash card, hard drive, CD, and then proposed the firmware found on the carrier.
  • Press the "ENTER" key, the update process will start, which will take a few seconds.
  • The operation is performed.

In the case of laptops, the BIOS update process is much easier. For Program, we take Lenovo laptops. To update the BIOS to the latest version:

  • Go to the official site of
  • In the search string on the right side of the main page, enter the model, for example - "G580".
  • Go to the Laptop Model page. At the top of the page, hover the key to the "Support and Warranty" item of the main menu, then click the "Drivers" link.
  • The new page will show a list. Find the "BIOS" section in it and open it.
  • Opposite the name available to download the BIOS firmware, click on the "Download" button.
  • BIOS firmware for laptops, as a rule, is an ordinary EXE file.
  • Run the installer and follow the instructions on the screen.

There are other (more complex) BIOS update methods. All of them involve the creation of a boot disk or flash drive with a pre-installed flasher installed on them.

laptop and biosHello.

Bios. "The thing is unobistant (when you normally work a laptop), but when problems with it can take a bunch of time! In general, the BIOS needs to be updated only in extreme cases when it really needs it (for example, that BIOS began to support new equipment), and not just because a new version of the firmware appeared ...

BIOS update is not difficult process, but requires accuracy and care. If you don't do something like that - the laptop will have to be included in the service center. In this article, I want to stay on the main aspects of the update process and all type of users who face it for the first time (especially since my previous article is oriented more on the PC and somewhat outdated: BIOS /).

By the way, the BIOS update can cause the equipment warranty service failure. In addition, with this procedure (if you error), you can bring a laptop to breakage, which can be corrected only in the service center. All that is described in the article Next - do at your own risk ...

ВAs well as update BIOS:

  • You can download new BIOS versions only from the official website of the manufacturer of your equipment (I emphasize: only from the official site), and pay attention to the firmware version, as well as what it gives. If there is nothing new among the benefits for you, and your laptop works fine - refuse to update;
  • When updating the BIOS, connect the laptop to power from the network and do not disconnect it from it until complete flashing. The update process itself is better to spend late in the evening (from personal experience :)) when the risk of powering off and voltage jumps will be minimal (i.e., no one will drill, work with a perforator, welding equipment, etc.);
  • Do not press any keys in the process of flashing (and in general, do nothing with a laptop at this time);
  • If you use a flash drive to upgrade - be sure to first check it: if there were cases that the flash drive in the process became "invisible", some errors, etc. - it is not recommended to choose it (select the one with which 100% is not There were previous problems);
  • Do not connect and do not disconnect any equipment during the flashing process (for example, do not insert other flash drives, printer, etc. into USB).

ПROTSEMS BIOS update (main steps)

On the example of the laptop Dell Inspiron 15R 5537

The whole process, as it seems to me, is convenient to consider, describing each step, conducting screenshots with explanations, etc.

1. Downloading the new version of BIOS

You need to download the new version of BIOS from the official website (the discussion is not subject to :)). In my case: on the site Through the search, I found drivers and updates for your laptop. A file to update the BIOS is an ordinary EXE file (which is always used to install ordinary programs) and weighed about 12 MB (see Fig. 1).

Fig. 1. Support for Dell products.

Fig. 1. Dell product support (update file).

By the way, files for updating BIOS do not appear every week. The release of the new firmware once in half a year is a year (or even less often), this is the usual phenomenon. Therefore, do not be surprised if the firmware will be a pretty old date for your laptop "new" ...

2. How to find out what version of BIOS do you have on a laptop?

Suppose you see the manufacturer's new version of the firmware on the manufacturer's website, and it is recommended for installation. But you do not know which version you have currently installed. Learn the BIOS version is very simple.

Go to the menu START (for windows 7), or press the button combination Win + R. (for Windows 8, 10) - in the Row to execute enter the command MSInfo32. and press ENTER .

Fig. 2. We learn the version of the BIOS via MSINFO32.

Fig. 2. We learn the version of the BIOS via MSINFO32.

A window must appear with the parameters of your computer, in which the BIOS version will be specified.

Fig. 3. BIOS version (Photo taken after installing the firmware, which was downloaded in the previous step ...).

3. Running the BIOS update process

After the file was downloaded and the update solution is accepted - run the executable file (I recommend it late in the evening, the reason pointed at the beginning of the article).

The program will again warn you about the update process:

  • - It is impossible to translate the system to the mode of hibernation, sleeping mode, etc.;
  • - You can not run other programs;
  • - Do not press the power button, do not block the system, do not insert new USB devices (do not disable already connected).

Fig. 4 Warning!

If you agree with all "you can not" - click the "OK" button to start running the update process. A window will appear on the screen with the process of loading a new firmware (as in Fig. 5).

Fig. 4. Process of updating ...

Fig. 5. Process of updating ...

Next, your laptop will go on a reboot, after which you will see the BIOS update process directly ( The most important 1-2 minutes See fig. 6).

By the way Many users are afraid of one point: at this moment the coolers begin to work at the maximum of their capabilities, which causes a rather strong noise. Some users are frightened that they did something wrong and turn off the laptop - in no case do it. Just wait for the end of the update process, the laptop will then automatically restart and the noise from the coolers will disappear.

Fig. 6. After rebooting.

If everything went well - then the laptop will download the installed version of Windows in the usual mode: you will not see anything new on the eye, everything will work as before. Only the firmware version will now be more newer ( and, for example, support new equipment - by the way, this is the most common reason for installing a new version of the firmware ).

To find out the firmware version (see whether the new correctly installed whether the laptop works under the old one), use the recommendations in the second step of this article:


I have everything today. The ladies are the last main advice: many problems when firmware BIOS occur due to hijling. You do not need to swing the first firmware, and immediately run it, and then decide much more difficult problems - it is better to measure "seven times - cut it once." Successful update!

BIOS is a firmware responsible for the starting boot of Windows. It checks the performance of components and add-ons. It depends on the correct loading of the computer and its normal operation (hardware components).

It is recorded on the motherboard, and not on the hard disk as OS. In new devices, the BIOS is replaced by UEFI, which performs the same functions, but improved. Both programs are sometimes required to update.

BIOS can be updated in several ways.

BIOS is a thin program, and therefore updating it better only in extreme cases. No need to update it on the normally functioning PC. This is associated with several factors:

  • To flash the BIOS on the Maternal Asus motherboard or any other difficult, the process requires some skills, the process goes through DOS;
  • Improvements will not be noticeable, since the differences in versions are minimal and narrowly specialized;
  • Perhaps the occurrence of problems and disruption, because The old version was tested carefully than new;
  • When conducting work, electricity should not be disconnected, otherwise the device will stop loading.

But sometimes you need to update the BIOS. If you are regularly encountered with a particular error in your work, go to the device manufacturer's website and check whether such an error is eliminated in the new firmware version. More often on the sites of manufacturers there is such a list. If such a problem is really solved in the new version, it makes sense to update the BIOS on a laptop.

Another weighty reason to flash BIOS is to install a new equipment. If you have acquired a new processor, which appeared after the release of your motherboard, it will not be supported by your BIOS. In new versions for firmware, manufacturers add support for new types of processors, and therefore will have to download such a file and flash the firmware.

Update BIOS is needed as a last resort. But even then, before updating, read the characteristics of the new version and find out whether the problems solved in it. Based on this and conclude whether to update the BIOS.

Find out the current version by climbing Win + R on the keyboard. In the window that opened window seems MSINFO32 for 32-bit OS. Click the Run button. A window will open with the enumeration of hardware and OS - device characteristics. Among them are finding the necessary.

Sometimes a notification appears that the outdated BIOS mode. This means that the operation of the BIOS is outdated, it still works in real, and not secure mode. The firmware may not help solve the problem, but it is not serious and eliminated not necessarily.

Methods of updates

The update method depends on the manufacturer of the computer, the model of the motherboard, etc. Most often, each manufacturer has its own refreshing instructions. You can get acquainted with it on the official website of the company.

The manufacturer's branded utility is the easiest and safest way to refresh the Bios Gigabyte, ASUS, MSI, supported by all major laptop manufacturers. It has a familiar graphical interface, check files for compliance, avoids errors. Before running the Utility from Windows, close all programs and stop all the processes that you can;

  • Update via DOS is a complex method suitable for experienced users. This method allows you to reflash the BIOS from the flash drive. First, the boot flash drive is created with DOS and BIOS. Sometimes there it is also necessary to record an additional utility for the update. But sometimes the downloaded update itself contains a BAT format file that launches DOS;
  • It is possible to update the BIOS on the PC and from the firmware itself. But this is possible only in his new versions and with the newest motherboards. The way simple and most correct, but in order to avoid errors, the user must be sure that he chose the correct firmware version. You need to open the BIOS as familiar and find the necessary utility in it, then run it. To update the BIOS from the flash drive, in the Utilities window, specify the media from which the update will be made.

On all modern motherboards or you can update the BIOS on your computer any of these ways. But it is better to choose the latter, as it guarantees the minimum number of errors.

Algorithm update

Update the BIOS Asus or any other modern laptop, can any of the three methods described. They have their own nuances, but when carrying out a process using utilities, are still not difficult.

From DOS.

Complex option with big risks. To update the BIOS on Windows 7 Computer Do the following:

  • Learn the model of your motherboard;
  • On the official website of the manufacturer, download the desired firmware version;
  • They are sometimes somewhat. In this case, choose the one that is intended for installation in DOS mode;
  • Create a bootable USB flash drive, DOS and an additional utility (it is downloaded on the manufacturer's website or enters the archive with the firmware);
  • Install the USB flash drive and restart the computer;
  • Specify the carrier on which the BIOS firmware of the motherboard;
  • After completing flashing, restart the PC.
More precisely, the instructions are not, as it varies for different PCs and boards. Find detailed instructions on the manufacturer's website. But it is not recommended to use this method.

From windows

Rebuild the BIOS on a laptop in such a way easy. Errors rarely occur. Popular method.

  • Download the firmware utility. She is its own for each manufacturer. The program for updating the BIOS ASUS - ASUS UPDATE, MSI - Live Update, etc.;
  • Install the program;
  • Run;
  • Find the online function - search for new firmware. In different programs, it is in different groups of teams;
  • From the list of firmware, choose the necessary one;
  • Activate downloading;
  • After downloading, run the flashing and follow the instructions of the program.

The BIOS ASUS, MSI firmware and others are safe in this way and therefore, the program itself selects the appropriate firmware version. In addition, an intuitive interface will help perform the firmware not even an advanced user.

From bios

Rebuild the BIOS on a laptop from the firmware is due to the pre-installed utilities. This is a difficult way, as it differs depending on the motherboard chip model, the manufacturer, etc. To update the BIOS on the Gigabyte motherboard, run the pre-installed @BIOS utility, from other manufacturers - other programs. Such programs are similar to utilities involved in the previous method, but not so comfortable. They work with them also - find the necessary file on the network and run.
