Resuscitation of laptop BIOS after unsuccessful firmware. How to restore the BIOS of a computer and laptop if it has crashed How to restore bios on an asus laptop

Will repair 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 successful. After a seemingly successful firmware, the laptop may simply not start or hang on the manufacturer's splash screen. This article discusses one of the Pheonix BIOS recovery methods.

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

A warning will appear, click OK

If everything went well, you will receive a message like this

If something went wrong, then

you need to restart the program and repeat all the steps

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

That's it, a USB flash drive with a 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, 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 to repeat all the steps again.

Hello dear readers.

Any computer is a complex system. Sometimes, during the 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 such an ailment - it all depends on the type of error. Later in the article I will tell you how to restore BIOS on a laptop, depending on the type of problem.

Restoring to factory settings

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

In most cases, this procedure helps. True, sometimes you can meet a simple error that does not allow the OS to start normally. It's easy to fix:

With a password

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

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

Important! Before moving on, there are a few key points to clarify. So, in some laptops, for example, Acer Aspire, not two, but three contacts are provided. In this case, you need to set the jumper to another position and wait a few minutes.

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

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

Recovery after firmware

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

The BIOS is a firmware written on a chip on the motherboard that is responsible for starting, testing, and configuring the hardware at boot.

If for some reason the BIOS is damaged or does not fit the board, either the computer is unstable or it does not boot at all. And the problem arises, how to restore the BIOS.

Bios recovery methods

If the operating system boots, but the computer does not work correctly, you can try flashing the BIOS from DOS or Windows:

• Download from the Internet from the BIOS manufacturer's website for your board and the Phoenix or InsydeH2O flash driver program.
• Make sure that the computer is connected to the network through an uninterruptible power supply.
• If you decide to reflash from Windows, you must turn off the Internet, network connection, unload all unnecessary programs and disable the antivirus.
• Dissolve the bios archive and run the bat file. The program will flash the BIOS and restart the computer.

If the computer does not boot:

• If the motherboard has the function of emergency recovery of a faulty BIOS, there is a Flash Recovery jumper on it. To restore the BIOS, you need to put it in the Recovery Mode position, install the special boot disk that comes with the motherboard into the drive, and turn on the computer. The program will overwrite the BIOS to the original version. After a few minutes, the computer can be turned off and the jumper returned to its original position.
• If the board does not have a BIOS recovery function, you can try flashing it on another motherboard that supports this type of BIOS. To do this, carefully remove the BIOS on the working board with a flat screwdriver and install it back so that its legs only touch the connectors. The computer boots into DOS. After loading, a working BIOS is removed, and a faulty one is put in its place and the BIOS update program is launched. After the flashing is completed, the computer can be turned off and the flashed BIOS removed from the board. The method of flashing the BIOS in another motherboard works, but it is dangerous in that you can damage the BIOS itself or the motherboard. Therefore, in this case, we strongly recommend that you contact the repair shop, where the BIOS will be flashed on a special programmer.

The problem of how to restore the BIOS of a laptop is solved in much the same way.

• From another working computer, go to the Internet and download the program to create a rescue disk Crysis disc. The easiest way to download these programs is from the site soft.ru. Take a flash, format it in fat32, write a program on it and downloaded from the Internet a suitable BIOS for your board.
• Remove the battery from the laptop. Insert a flash drive into a USB port. While holding the Fn and Esc keys, turn on the laptop's mains power and turn it on. BIOS recovery will take only a few minutes and the laptop will reboot. After that, the battery can be returned to its place.

If you experimented with BIOS settings and your computer began to work incorrectly, you need to return the previous settings. How to restore BIOS settings:

• Restart your computer and go into BIOS. In the exit tab, find the Load Setup Defaults item, which means restoring the default settings and click on it. After that, the computer will restart with the already restored settings. However, this method does not always work.
• If it was not possible to restore the settings programmatically, you need to turn off the computer, unscrew the screws and remove the side cover. On the motherboard, you need to find the battery that is responsible for saving the BIOS settings. If there is a jumper next to it, put it in a different position to reset the settings.
• Instead of a jumper, there may be a button, next to which there should be an inscription CMOS. In this case, to reset the settings, simply press the button.
• If there is no jumper or button, the battery itself should be pulled out for a while. To do this, press the latch with a screwdriver, after which the battery can be easily pulled out. After a few minutes, you can put the battery back in and boot up your computer. BIOS settings will be standard.

As a result of unsuccessful firmware, the laptop may completely lose its performance.
Symptoms:
- When you turn on the black screen, the fan is buzzing, some indicators may be on. And then nothing happens. Turn off the button, too, most likely does not work.
- When turned on, some inscriptions appear on the screen, but the laptop hangs or turns off at the very beginning of POST (self-test).
Restoration of working capacity in the service center will cost 1 ... 3 thousand rubles. In addition, this case is usually not considered a warranty.

Firmware (firmware) - a set of programs and data that are necessary for initialization, testing and organizing the coordinated work of computer components at the initial stage, until the operating system is loaded, and possibly further. Usually the motherboard designer writes it on the chip EEPROM(electrically reprogrammable read-only memory).

BIOS- basic (basic) input/output system. The main (but not the only) part of the firmware (firmware). Since the main one, in Russian, BIOS and firmware are one and the same.

UEFI (EFI)- further development of the firmware in the direction of expanding the capabilities of the BIOS. You can read more here: http://ru.wikipedia.org/wiki/UEFI

Why change the firmware?
When developing any complex equipment, it is not possible to take into account all the nuances. When it becomes necessary to make changes, the manufacturer releases a new firmware. Unfortunately, when writing a new firmware, there is a danger that it will be inoperable. Reasons for mongo: poor-quality firmware, failure during the recording process, chip damage EEPROM and etc.

In the firmware of almost all modern motherboards there is a small program that allows you to read the firmware from a USB flash drive (previously from a floppy disk, sometimes from a CD / DVD) and flash (write) it into a chip EEPROM. She is located in boot block-e - chip protected area EEPROM. You can also overwrite it, but for this you must first unlock the record. This is done so that if there is a failure during the firmware write, it can be restored.

We will discard cases when the operation of the laptop is impossible due to hardware malfunctions or chip failure. EEPROM.

Consider the sequence of actions for resuscitation of a laptop ASUS M60J . For other models of manufacturers, options are possible, but the general scheme is the same.

A patient: ASUS M60J
Firmware: APTIO (AMI UEFI)
Symptoms: The firmware process has completed successfully. After that, the laptop, as expected, automatically turned off.
Black screen when turned on. Fan hums. There are no sounds in the speaker. The media bar flashes. After about 5-7 seconds, it goes out, only the volume scale remains, then after 3-5 seconds it goes out. The laptop does not respond to anything. You can turn it off only by holding the button for a long time or by unplugging the power cord from the outlet and removing the battery.

You will need:
1. A flash drive (USB flash drive) with a capacity of no more than 2GB, formatted in FAT16 (or just FAT). A larger flash drive formatted as a hard drive with a partition up to 2GB is not suitable. No need to write loaders and operating systems to it. Only the firmware file is needed.

By the way, I tried to slip the firmware on the card microSD 2GB inserted into a micro card reader (slightly larger than the card itself, sold as a kit). It's me that in Windows this combination is defined as a card in a card reader, and not as a regular flash drive. Therefore, jambs are possible when it is not the operating system that works, but the stub in boot block-e. However, it rolled. Although there is one drawback - the card reader does not have an activity indicator, but it turned out to be very necessary for blind experiments.
Perhaps a mobile phone or an MP3 player with an appropriate amount of memory with support for the UMSD but I haven't checked.

2. Firmware file downloaded from the manufacturer/developer website.
3. A working computer for preparing a flash drive.

On a working computer, extract the firmware file from the archive. I downloaded M60JAS.210.
Rename it to M60J.BIN.

How did you come up with the file name?
Connected the hard drive to the working device. Accidentally discovered a hidden file in the root of the system partition M60J.BIN and the size suspiciously matches the firmware (2,228,224 bytes). I don't know where he came from. Either Windows pulled it out of the chip, or winflash duplicated during the firmware ...
For other models, the file name will most likely be different, corresponding to the model name.
boot block earlier models understood only standard names: AMIBOOT.ROM, AMIBOOT.BIN

Write the file to a flash drive. (It is recommended to clean the flash drive from unnecessary files or format it beforehand)
Turn off the power of the laptop (unplug the power supply from the network).
We take out the battery from the laptop.
Insert the flash drive into the USB port. It doesn't matter which one. (According to rumors, in other models you need to find right port)
Press and hold keys + .

In different models and from different developers, other key options are possible. Usually found:
+
+
+
+
+
+
+
+

Turn on the power (from the network, plug the power supply into a socket).
Pressing and releasing the button .
- All indicators on the multimedia panel light up
- The indicator on the flash drive blinked
- The indicators of the multimedia panel have gone out. Only left to burn and (two locks)
- flash drive stays on
Let go of the buttons + .
- The hard drive activity indicator blinked
- flash drive flickered
- After a few seconds, the laptop itself rebooted.
- There was a corporate splash screen.
- Launched automatically Easy Flash(built-in flash driver). We sit, do not touch anything and observe the firmware process. It will take a minute, maybe five. If it slows down at times, don't worry and don't rush to poke buttons.
- When the firmware is over, the laptop, as expected, turned itself off.
Everything. Now he is ready to go.
You can put the battery back. Or try turning it on directly from the AC adapter.

In conclusion, I note that different laptop models have different sets of indicators. To decide what and how to do, you need to carefully monitor their condition. In any case, according to the indicator of the flash drive, you can understand whether information is read from it or not.
In case of ASUS M60J I have tried various key combinations. The flash drive didn't light up at all. And the multimedia panel, when turned on, all flashed and went out after 5-10 seconds. After that, he didn't react to anything.
When I picked up the correct key combination, but had not yet figured out how to name the firmware file, the panel went out, but remained lit and . The activity indicator of the hard drive and the flash drive flashed 2-3 times. After that, the flash drive remained lit with a steady light, and the laptop beech no longer reacted to anything.

If you did everything as it is written in the article, but the firmware from the flash drive still does not load, write the firmware file to CD, and then - in the text.
Basically logical. Working with built-in CD/DVD/BR is not based on the simplest access to ports. A with USB devices is much more difficult.
