Hello dear readers.

Any computer is a complex system. Sometimes during operation of the device, some problems may appear related to the correct performance of its functions in an area such as the BIOS. There are several ways to solve this problem – it all depends on the type of error. Later in the article I will tell you how to restore the BIOS on a laptop, depending on the type of problem.

Restore to factory settings

If suddenly the device stops functioning normally, and you suspect that the reason for this is incorrect settings in the area mentioned above, you can try to return them to factory settings:

In most cases, this procedure helps. True, sometimes you can encounter a simple error that does not allow the OS to start normally. The fix is ​​simple:

If you have a password

Sometimes users may encounter a situation where someone or they themselves previously set a password for the area we need, and conveniently forgot it. As a result of several incorrect attempts, the device will simply stop functioning.

Then you need to open the mobile computer itself. By the way, this method will help if it does not turn on:

Important! Before we go any further, there are a few basic points to clarify. So, some laptops, for example, Acer Aspire, have not two, but three contacts. In this case, you need to set the jumper to a different position and wait a few minutes.

In addition, sometimes you can find a special small button that performs the same functions. You just need to press it with a pencil for a few seconds.

Another solution is to remove the battery that maintains all important data in memory. If you remove it, everything will be reset.

Recovery after flashing

If problems arise as a result of unsuccessful installation of a new software version for the corresponding component, you need to perform a series of steps.

If the BIOS has crashed on your PC or laptop, then this is by no means a reason to panic, although, of course, this situation cannot be called very pleasant. However, in many cases, you will be able to cope with this problem yourself and restore the functionality of your PC or laptop without the help of computer specialists.

Suppose you turn on the computer and instead of the usual picture of it loading, you see some kind of text error message, after which the computer stops loading. Or you hear indications of a BIOS error.

The first thing that is recommended to do in this case is to restart the computer. This error may be due to a BIOS failure, which occurred, for example, as a result of a power surge. If this method does not help, then this means that the problem really lies in some kind of hardware malfunction associated either with the BIOS itself or with some other hardware component.

It should be borne in mind that not every error message that appears on the screen indicates a malfunction of the BIOS itself. In most cases, text error messages are displayed when there is a problem with some other component of the PC, such as RAM, hard drives, or floppy drives. More information about text error messages is described in a separate article. Therefore, you should carefully read the message displayed on the screen and check the hardware component that is mentioned in it.

However, if you see an error message that mentions the BIOS (or CMOS), then it is most likely a BIOS-related problem. Also, in some cases, BIOS errors may be indicated by sound signals emitted by the motherboard speaker. You can get information about which signals in which BIOS versions may indicate a BIOS malfunction from the corresponding article on our website.

Solving problems with crashed BIOS

If you encounter an error, the source of which is indeed the BIOS itself, then first of all you should try resetting the BIOS to the initial settings. There is a high chance that after resetting the BIOS to factory defaults, the BIOS error will disappear. You can read more about how to reset BIOS settings and what you need to do to do this in the corresponding article on our website.

A BIOS error can often be associated with a dead BIOS battery. Therefore, you should try replacing the battery with a new one. You can also read about where to find this battery and what needs to be done to replace it in the article on our website.

But what should you do if resetting the BIOS and replacing the battery do not help? Then you will have to resort to another method of restoring a faulty BIOS - flashing it again. BIOS firmware is updated using a file containing an updated BIOS version. As a rule, the new firmware version can be downloaded from the website of the manufacturer of your computer or motherboard. There you can usually find instructions for the firmware itself.

As a rule, external media are used for flashing the firmware, onto which the update file is written. The firmware itself is installed when the PC is rebooted. There are also programs that allow you to flash the BIOS from under Windows, without rebooting, however, in the case described, most likely, they will not be of use to you, since, as a rule, if there are serious problems with the BIOS, the operating system cannot be loaded.

If all the methods described above did not help restore the functionality of the BIOS, then you have only one thing left to do - take the computer or motherboard with a faulty BIOS to a computer service center. Or buy a new motherboard.

Conclusion

No computer is immune from problems associated with BIOS failure. And therefore, any user should know what to do in such a case, which cannot be called pleasant at all. However, statistics show that cases of physical failure of the BIOS chip occur infrequently compared to failures of other components of the motherboard. Therefore, methods such as resetting the BIOS settings, replacing the battery powering the BIOS memory and re-flashing the BIOS on a PC or laptop in most cases help solve this problem. But if none of the above methods help, then you have no choice but to take the computer to a service center.

How to restore a laptop via BIOS: working solutions

Unfortunately, no OS is immune from a sudden crash; when this does happen, users are interested in - how to restore a laptop via BIOS on one's own? Those who have already walked this path and know what the essence of all the difficulties are, feel simply omnipotent. If the user is thinking about this issue, it means that his affairs are very bad and the usual recovery is out of the question, since the OS does not load at all.

Most often, when such a problem arises, not only a beginner, but also an expert simply reinstall the OS. Of course, this is the easiest way out of this situation, but why spend a lot of time reinstalling if there is a faster option.

How to restore a laptop via BIOS,
using DOS?

It is worth understanding that DOS is a relatively small OS, which is most often stored on a regular disk or flash drive. After startup, this system gains full access to managing all hard drives and access to the BIOS menu. Using a DOS system allows you to revive the operating system with minimal losses. Thanks to the possibility of low-level control, it is possible to make the necessary settings and correct surgical punctures with pinpoint accuracy.

Common recovery methods:

1. Initially, you can use a disk image or flash drive as an assistant. You must act in the following sequence:

• Take the disc with the OS that was installed on the laptop and insert it into the drive.
• You need to restart your laptop.
• With a frequency of 1 click per second, you need to press one of the buttons: “Delete”, “F8” or “F2”, which serve as an entrance to the BIOS menu.
• Once in the menu, you need to go to the “Boot” section (in different versions of microsystems, this menu may be called differently).
• Using the arrows, you need to install a disk drive or flash drive as a bootloader.
• Save all changes.

When the laptop reboots, just select “System Restore” and proceed to recovery.

2. “Almighty” command line. Sometimes, this method is rightfully considered a real salvation. The command line allows you to correct basic errors in the operation of the hard drive so that the system comes to life.
We reboot the laptop and press the BIOS entry button several times, after which we perform the following steps:

• You need to select the line “Safe Mode with Command Prompt”;
• When you are transferred to the operating system environment, you must enter “rstrui.exe” into the command line and click “Next”;
• All that remains is to choose a suitable backup copy.

This procedure allows you to roll back to a working state of the system.

3. Restoring laptop BIOS through safe mode. When restarting the laptop, you need to press the “F8” key. From the list that opens, select the “Safe Mode” line. Depending on the operating system version, this item may have a different name. It is designed to run the system with only the most necessary functions.

When the system boots, you must:

• Go to the control panel via “Start”;
• In the list you need to find the line “Recovery”;
• In the window that opens, select “Run system recovery”;
• From the list provided, you need to select a working backup copy and wait for the restoration to complete.

This recovery method is suitable for absolutely all versions of the OS, but with some features in Windows8. This version of the OS may simply not enable “Safe Mode”, since there is often resistance from programs. But even in this case there is a simple way out:

• Install a boot disk/flash drive;
• Select “System Restore” in the lower corner;
• Go to the “Diagnostics” area;
• Select “Advanced options”;
• And we get to the desired “Command Line” by writing (bcdedit /set (globalsettings) advancedoptions true);
• Now, you need to exit the menu and select “Continue”.

This method is considered very universal for Win10, and is also a real godsend for those whose laptop is equipped with an SSD drive.

4. A life-saving option for those whose laptop does not have a restore point, but has an operating system installation distribution.
Procedure:

• At the first stage, you need to repeat the same steps as in point 1;
• Select “System Restore”;
• At the next stage, we carry out all the steps from the instructions, which help to make the right choice during the entire installation process;

Upon completion, everything will be restored, but with the exception of previously installed programs. Unfortunately, they will have to be installed again.

The new Refresh Your PC feature for Windows8 deserves special attention. This function is simply a lifesaver and a real find for beginners, who will need a minimum of action during the recovery process. In case of a critical error, the OS itself opens the recovery menu. By clicking on “Diagnostics” and “Restore”, the system will return to a fully working state.

The system can also be restored from an archived image. Thanks to the built-in recimg utility, which very quickly creates an OS image and remembers its storage location. Next time, the system will be restored from this archive.5 Rating 5.00 Vote - support the service!

Before touching on questions about BIOS (Basic Input Output System) firmware, it is worth recalling what a BIOS is and why it is needed.

When you turn on a laptop or computer, the first thing that is loaded is a small program that checks whether all devices are working, configures these same devices, and it is this program that launches the operating system bootloader. Simply put, BIOS is a very important piece of software. Without it, a laptop or computer simply will not boot. The procedure for checking and setting up equipment is also called POST (Power On Self Test).

While the main BIOS is running, it is also possible to execute other similar programs. Usually this is the BIOS of the video card, as well as the BIOS of other complex devices such as some RAID controllers. At the end of execution, control is transferred back to the main BIOS.

The program itself (BIOS) is stored on a memory chip on the motherboard. This chip can be reflashed by updating the same program.

Like any self-respecting program, the BIOS has settings. These are the ones we can change when entering the settings menu. On Acer, eMachines and Packard Bell laptops, this menu is accessed by pressing the F2 key. Only a small part of the settings is available to the average user. There are actually a lot of them. All these settings are stored in EEPROM memory. They are the ones that are reset when you remove the small battery on the motherboard or switch the corresponding jumper.

So, we seem to have found out what BIOS is. Now let’s decide on the question of why it should be updated at all, i.e. Why flash the BIOS?

Flashing the BIOS of a laptop is recommended in case of any problems that may be related to the laptop devices; it is not worth chasing just the new version, because In some cases, the firmware may cause the laptop to not work. As they say, it works - don’t touch it))
This is on the one hand.

In the latest BIOS version, developers usually fix identified bugs of the previous version and add new features that generate new bugs and so on in a circle until the developer gets tired and the flow of indignant user letters dries up.
Usually, new BIOS versions fix many errors and add support for new devices.
They usually add support for new laptop hardware, such as new types of processors, video cards, more memory, and also eliminate problems such as spontaneous password occurrence, processor operation only at a reduced frequency, display inoperability after resuming from sleep mode, incorrect operation of function keys, dusty , cloudy screen, change in fan speed depending on the load, these can be various errors that are related to the operation of the video card, Wi-Fi adapter, sound, Web camera and many other devices, etc.
This is from the other side.

In general, it is up to the user to decide whether to flash the BIOS or not. And he and only he is responsible for this decision.

The latest BIOS version for your laptop model can be found on the manufacturer’s website in the section Drivers. For Acer This .
Download the latest version specifically for YOUR laptop models. This note is very important to take into account!
If you don’t accept it, you’ll have to part with your laptop and be on your way to a repairman’s house))) In the best case, you’ll have to “dance with a tambourine” to restore the BIOS, or the flasher will simply refuse to flash the chip due to incompatibility of BIOS types.

The description of the changes is usually located in a file called release in the BIOS archive or just a couple of lines of description on the BIOS page.

Need to flash ONLY BIOS from HIS laptop models.

Instructions for the firmware are also located in the archive with the BIOS in a file called readme. Usually you need to run a file with the bat extension from the same archive, or exe, if the developer has packaged the BIOS, instructions for the flasher, and the flasher itself in it for the convenience of users. Like, one click and you have new firmware.

A flasher, also known as a flasher, is a program that flashes the BIOS.

A collection of flashers for DOS and Windows from Phoenix And InsydeH2O can be downloaded from the link: download
You can flash it from Windows or from DOS. It is believed that DOS is much safer, but the author of these lines has repeatedly flashed the BIOS from Windows without fatal consequences. You just need to follow some simple safety rules:
- close all running programs, antivirus;
- disconnect all network connections, internet;
- charge the battery, connect the mains power;
- disconnect (if connected) all (except the mouse) devices connected via USB
If you are flashing in Windows Vista or Seven, run the executable file as an administrator. The battery must be inserted and charged at least 30%, or better yet, fully charged. The process itself takes a minute or two.

It is advisable to run the file with the bat extension from the BIOS archive. The archive with the BIOS can first be unzipped into a separate folder. The fact is that for some models, for example Acer Aspire 5530, it prescribes non-trivial actions when flashing the firmware.

@echo off bioschk3.exe if errorlevel 1 goto SouthBridgeROM:ECROM echo EC Side... PHLASH16 jalb111.wph /c /x /s /bbl /pn /mode=3 goto exit:SouthBridgeROM echo SB Side... echo EC Updating ... call spi /flash -bFD60 -v20000 -i -nid k26a111a.rom PHLASH16 jalb111.wph /c /x /s /bbl /pn /mode=3:EXIT

I think that if in some versions of this laptop model you simply flash the BIOS (without additional firmware for the keyboard controller k26a111a.rom) something terrible will happen (for the owner;)) By the way, from this bat it’s also clear that when flashing the firmware, the bootblock(which is not common), which means that if problems arise during the firmware, then the likelihood of recovery using Crisis Disk decreases.

However, this is rare. Usually, just flashing your BIOS is enough.

Phoenix BIOSes have the file extension .wph, .rom, and InsydeH2O .fd.
It should be noted that if the archive contains both .wph and .rom files, then the latter is a BIOS backup (image) and cannot be flashed - it does not have service information for a flasher at the end of the file, but it is quite suitable for a programmer.

By the way, if you downloaded the latest BIOS firmware from the Acer website for yours model, but the flasher refuses to flash it - it says that the version is incorrect (and your BIOS is almost the first available version, “from the time of Ochakov and the conquest of the Crimea”), you can try, following the example, try first to flash not the latest version, but some intermediate one.

BIOS firmware

If you do not want to run the bat file from the archive (perhaps you are smarter than the developers, or they forgot to put it there), then:
(The following applies to the Phoenix BIOS, although with the InsydeH2O BIOS the procedure is approximately the same)

1) you can flash the BIOS from DOS

Just in case, prepare a Crisis Disk, it will be discussed below.

Create a bootable USB flash drive, according to the article

We write a flasher and a BIOS file to it

Launch the flasher, examples:
If the bios is from Phoenix:
phlash16 /x /c /mfg /mode=3 my_bios.wph
If the BIOS is from InsydeH2O:
flashit my_bios.fd /fe /b

These are almost standard options, more about them below. If you need something specific, add additional firmware options to your liking. But, generally speaking, it is better to look into the bat file, which should be in the archive in the DOS firmware, and copy the options for the flasher from there.

After flashing the firmware, the laptop reboots and voila - you have new firmware. This is if everything went smoothly. By the way, before flashing the new one, you can make a backup of the old BIOS, the key is /BU.

Close all running programs, disable antivirus, disconnect from the network and the Internet
The BIOS file should be in the same folder with the flasher. YOUR laptop models
Run Winflash or Winflash64 as administrator
First, make a BIOS backup without flashing
If you need something specific, click the Advanced button
Flashing the BIOS

Restoring BIOS in case of unsuccessful firmware

What to do if everything goes wrong? During the firmware update, the laptop froze and had to be turned off, they flashed the BIOS from another laptop model, someone accidentally launched an antivirus, the music played well during the firmware, but not for long...

It’s worse if you do everything according to the instructions, but it turns out like a crooked idiot, although, in general, you’re not like that (okay, let’s respect the equality of citizens - you’re not like that)!

In general, if after rebooting or turning on the laptop (immediately after flashing the firmware) you see a black screen, the system does not boot, although the cooler is working, and the indicators are lit or blinking, or the laptop beeps - you have two options.

1) make a Crisis Disk and use Crisis Recovery Mode to try to restore the BIOS.

Attempts almost always end successfully (if the BootBlock BIOS was not damaged during the previous firmware)

2) flash the BIOS on the programmer by unsoldering it yourself or taking it to a service center.

In principle, you can also make a programmer yourself, example No. 0, example No. 1, example No. 2, example No. 3, ...

A little explanation of the meaning of the process.

The Phoenix BIOS recovery procedure uses a boot-block. Boot-block contains code that allows you to boot the system in Crisis Recovery Mode (CRM). During normal booting, the BIOS, after turning on the laptop, queries all laptop devices and if all devices critical for operation are identified, the system boots. In this case, the results of the Power-On-Self-Test (POST) diagnostics can be seen if you have the so-called. POST card. The BIOS signals some POST codes with a beeping sound. Table of POST and Beep codes for PhoenixBIOS

If you boot into crisis recovery mode (CRM), then the devices are not polled; the BIOS firmware starts immediately, unless, of course, a USB FDD (floppy drive) or USB Flash (flash drive) with a crisis disk is connected to the laptop. CRM only runs basic laptop systems. You will not see anything on the screen, the keyboard and hard drive will not work.

So, how to flash the BIOS in Crisis Recovery Mode.

First you need to disconnect all devices from the laptop (mouse, keyboard, USB devices, printers, external monitor, etc.), remove disks and floppy disks, and also remove the battery.

00 - disconnect the power adapter from the laptop
01 - connect USB FDD or USB Flash with Crisis Disk to laptop

03 - connect the power adapter to the laptop
04 - turn on the laptop (press the Power button).
05 - in about 10-15 seconds. release the and buttons (after the activity indicator on the FDD drive lights up, goes out, and lights up again, and reading from the floppy disk (or flash drive) begins).
06 - the system should start booting from the FDD (or flash drive)
07 - the process takes ~ 3-5 minutes. and GOES WITH A “BLACK” SCREEN! (i.e., nothing is displayed on the screen; the fact that the process is in progress can be seen by the activity indicator of the FDD drive (or flash drive))
08 - at the end of the process, reading from the FDD drive will first stop, the FDD drive activity indicator will go out, and then after some time (~ 1-2 minutes) the laptop should automatically reboot.

InsydeH2O

The BIOS flasher from InsydeH2O is built-in, so there is no need to copy it to a flash drive.

Prepare a working computer with a USB FDD drive or USB Flash
- insert a blank floppy disk (or flash drive into a USB port) into the drive and format it to FAT32
- copy the BIOS file for YOUR laptop model, previously renamed, onto it.
You can find out the name from Acer support or look it up in the service manual, ask here on the website, in the topic "Prabivis..." :), and you can also run PhoenixTool(the latest version can be downloaded from the link here), feed it your BIOS file, get this picture

"?" - this is a glitch, it's actually "d".
You can also then look into the BIOS folder and open SLIC.txt


Those. in this case, the correct BIOS file name for flashing the firmware in Crisis Recovery Mode is BIOS.fd

Further:
00 - disconnect the power adapter from the laptop.
01 - connect a USB-FDD drive with a floppy disk or USB Flash to the laptop
02 - press and hold the and buttons (hold until step 06).
03 - connect the power adapter to the laptop.
04 - turn on the laptop (press Power Button).
05 - in about 10-15 seconds. release the buttons and
(after the activity indicator on the FDD drive or USB Flash lights up, goes out, and lights up again, and reading from the floppy disk begins).
06 - the system should start booting from FDD or USB Flash
07 - the process takes ~ 3-5 minutes. and GOES WITH A “BLACK” SCREEN!
(i.e., nothing is displayed on the screen; the fact that the process is in progress can be seen by the activity indicator of the FDD drive or USB Flash)
08 - at the end of the process, reading from the FDD drive (or USB Flash) will first stop, the FDD drive (or USB Flash) activity indicator will go out, and then after some time (~ 1 minute) the laptop itself should turn off.
09 - press the Power button - the system should work.

If the BIOS is not flashed, it means the file name was incorrect.

P.S. If the reading indicator blinks for more than 15 minutes, the laptop can be turned off, which means something went wrong.

What to do if you can’t log into CRM.

Happens. If you are sure that your boot block is safe and sound, you can try different “shamanic dances with a tambourine”:

Try installing a fully charged battery before starting the BIOS recovery process;
- try a small capacity flash drive (such as 128-256Mb, up to 2Gb is also suitable), or even better USB FDD (for bios from Phoenix);
- try to remove the hard drive and DVD drive;
- try connecting the device with Crisis Disk to different USB ports of the laptop;
- try different versions of Wincris.exe (for bios from Phoenix);
- try different versions of phlash16 (can be found in the first part) (for bios from Phoenix);
- try other key combinations Fn + B, Fn + Home, Win + B or Win + Esc, Ctrl + Home (although for Acer Fn + Esc or, sometimes, Fn + B or Fn + Home are usually suitable).
Pressing the Power button again helped someone.
Someone found it helpful to press the Esc key again after pressing the Power button.
Installing a battery helped someone after connecting the power cord.
Jerking the BIOS battery helped someone.
And for some, installing only one memory stick in the lower (first) slot.

Firmware on the programmer will help everyone))

P.S. Discussion of successes and failures in firmware, where to find the required bios file, how to rename the bios file from InsydeH2O, etc. and so on. It’s better to post in the appropriate forum topic

Edited by: reylby- December 27, 2016
Reason: Added a way to find out the correct file name

He will carry out repairs and solve your problems within a few minutes.

Updating computer software (installing programs, installing an operating system) requires certain knowledge and skills. They are especially necessary when updating the BIOS, and not always having certain knowledge and acting strictly according to the instructions, the firmware is installed successfully. After a seemingly successful firmware update, the laptop may simply not start or may freeze on the manufacturer's splash screen. This article discusses one of the methods for restoring the Pheonix BIOS.

1) A working computer with an Internet connection is required
2) Download the BIOS for your laptop model from the manufacturer’s website
3) Download the Bios Recovery utility, unpack it to the desktop, there are different versions in the folder, try with the newest one, if it doesn’t work, try older versions!
4) The BIOS is supplied by the manufacturer in a self-extracting or simple archive; you also need to unpack it to your desktop and find the file with the .wph extension, no matter what it is called, rename it bios.wph and copy it to the folder with the BIOS recovery utility.
5) To restore, you will need a flash drive with a capacity of no more than 4GB, insert it into the USB port.
6) Now run the file wincris.exe
The program window will open, click START

A warning will appear, click OK

If everything went well you will receive a message like this

If something went wrong, then this,

you need to restart the program and repeat all steps

If you did everything correctly, this window will appear, click no

That's it, the flash drive with the BIOS recovery dump has been created!
7) Now turn off the laptop and remove the battery, the flash drive remains inserted into the USB port
8) Without inserting the battery, hold down the Fn+R keys and press the power button, insert the power cable and hold the keys pressed for a while (10 seconds)
9) That’s it, we leave the laptop and wait, I’ll tell you right away that you won’t see any actions on the laptop screen. The BIOS should recover automatically within 2-5 minutes. If this does not happen, try repeating all the steps again.

BIOS recovery on Lenovo S10-2(verified)

1. On a clean flash drive formatted in FAT16 or FAT32 format, write the file KIUN0113.ROM, renaming it KIUN0IA32.FD
2. Turn off the power to the netbook and remove the battery
3. Press and hold the Fn+B keys
4. Connect the power supply and press the power button ( hold the keys)
5. After 5-7 seconds, release Fn+B
6. The recovery procedure should begin
7. The computer will beep every 2 seconds - the process is in progress Lenovo BIOS firmware
8. The computer will turn off automatically when the firmware is completed

For Lenovo y550p laptop

I spent a lot of time on the above method - every time the same thing
- the cooler starts up to maximum, 30 seconds pass, one long beep is heard (read the flash drive), three short beeps (did not find the required file).
The solution has been found!
1. download from the office. website BIOS version (1ECN33WW(V5.07x64).exe)
2. right click on the file - WinRAR - Extract files!
3. find the file NIWBA507.fd and rename it to NIWBAx64.fd
4. We throw this file onto the formatted flash drive.
5. Next we turn it on by pressing fn+r, without battery.
6. will start beeping every 2 seconds.
