Recovering bios after unsuccessful asus firmware. How to recover the system on an Asus laptop. BIOS login and OS recovery on lenovo laptops

If the BIOS 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. Nevertheless, in many cases, you can independently cope with such a problem and restore the performance of your PC or laptop without resorting to the help of computer specialists.

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

The first thing to do in this case is to restart your computer. Maybe, given error associated with a failure of the BIOS, 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 are problems with any other PC components, such as RAM, hard drives or floppy drives. Read more about text error messages 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 BIOS (or CMOS), then it is most likely a BIOS-related malfunction. Also, in some cases, BIOS errors may be indicated by sound signals from the motherboard speaker. Information about which signals in which BIOS versions may indicate a BIOS malfunction can be obtained from the corresponding article on our website.

Solving problems with a crashed BIOS

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

A BIOS error can often be associated with a discharged 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 you need to do to replace it in the article on our website.

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

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

If all the methods described above did not help restore the BIOS to work, then you have only one thing to do - take the computer or motherboard from faulty BIOS to a computer service center. Or purchase 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 is by no means pleasant. However, statistics show that physical failure of a BIOS chip is rare compared to failures of other motherboard components. Therefore, methods such as resetting BIOS settings, replacing the power supply bIOS memory batteries and flashing the BIOS on a PC or laptop in most cases help to solve this problem... But if none of the above methods helps, then you have no choice but to take the computer to service center.

Hello friends! In today's article, we are with you update the motherboard BIOS aSUS boards ... This is a serious matter and must be treated accordingly. The process of updating the BIOS of any motherboard, although very simple, but any mistake in it will cost you dearly - you will have to return the motherboard to life in a service center, since you probably do not have a special programmer. At the beginning of the article, I will briefly remind you what BIOS is.

How to update BIOS on an ASUS motherboard

BIOS is the most important element of the computer - the firmware written on the microcircuit, which in turn is located on the motherboard.

BIOS - provides basic OS access to the hardware capabilities of the computer. In simple words, the BIOS explains to the operating system how to use this or that computer component.

Immediately after switching on system unit, BIOSchecks all devices (POST procedure) and if any component is faulty, thenthrough a special speaker, a signal is heard by which you can identify a faulty device. Eif everything is fineBIOS will start looking for the OS bootloader code on the connected drives and find it passes the baton to the operating system.

Now about not so good. The BIOS update process itself lasts a couple of minutes, but if at this time, the electricity in your house will be cut off, and your computer is not connected to the source uninterruptible power supply (UPS), then the firmware will malfunction and you simply will not turn on the computer. For recovery, you will have to look for a special programmer (BIOS recovery is a topic for a separate article).

I must say that manufacturers have foreseen the seriousness of the issue at the dawn of motherboard production completely excluded the possibility of updating or flashing the BIOS, only recently, BIOS began to be completed special program for your update. But still,updating the BIOS of any motherboard usually happens once in its life, and sometimes never at all.

The most important rule is if the work of a computer or laptop youquite satisfied, then nothing needs to be updated, but eif you still decideupdate BIOS, then there must be good reasons. Here are some of them.

There are no new features in your BIOS. For example, no technology AHCI, but there is only an outdated IDE, but you bought a new interface hard driveSATA III (6 Gb / s) or at all solid state drive SSD. Technology AHCI will allow your drive to use modern capabilities and the operating system on the new hard drive will run faster than in the IDE. Having visited the website of the manufacturer of your motherboard, you saw that a new update was released on BIOS, you also found out that after the update, your motherboard will supportAHCI! In this case, you can update the BIOS without hesitation.

A friend of mine lost sound on his computer reinstall Windows and the drivers did not help, he decided that the built-in sound card and bought a discrete one, so the sistemnik worked for 7 years, then the processor had to be replaced on this computer, this required updating the BIOS, after the update the built-in sound card worked.

One more case. The client's computer was constantly rebooting and reinstalling the operating system did not help, they replaced everything in the system unit, they did not change only the motherboard and processor. Finally decided to install new firmware on the BIOS and it helped!

In the "System Information" window that opens, we see the BIOS version - 2003

Now go to the official website of the manufacturer of our motherboard ASUSP8Z77-V PRO and choose "Drivers and utilities"

We select any operating system and open the "BIOS" item. We see that there is update 2104 (more a new versionthan ours).

Click on the "Global" button and download the firmware.

Fresh firmware for BIOS (P8Z77-V-PRO-ASUS-2104.CAP) downloaded in the archive. We extract it from the archive and copy it toUSB-f leshka. The firmware weighs 12 MB.

The USB flash drive must be formatted in file system FAT32 and apart from updating the BIOS should not contain anything.

Reboot and enter BIOS.

In the initial BIOS window we see old version firmware 2003.

We press "Additionally" and go to the additional BIOS settings.

(Click on the screenshot with the left mouse to enlarge)

We enter the "Service" tab

Select the BIOS firmware utility - ASUS EZ Flash 2 or you may have ASUS EZ Flash 3.

In the ASUS EZ Flash 2 window, we see our USB flash drive with firmware P8Z77-V-PRO-ASUS-2104.CAP.

Left-click on the firmware file.

Click "OK"

Update BIOS?

BIOS firmware is a delicate procedure, so you need to approach it with special care. Sometimes, however, all precautions do not help - force majeure occurs, during which the firmware files are damaged. Most motherboard manufacturers have tools for recovering from such failures, and today we want to talk about those for ASUS motherboards.

Working with the tool in question consists of two stages: preparatory and direct BIOS recovery. Also consider possible problemsthat may arise during the execution of instructions.

Step 1: preparation

The efficiency of recovery largely depends on the correct execution of actions at the preparatory stage, so it is important to carefully follow the algorithm described below.

On this preparatory stage completed, and you can proceed directly to recovery.

Step 2: Using ASUS CrashFree BIOS 3

Since technically using the utility in question involves flashing the BIOS, the first step is to make sure that the computer is connected to an uninterruptible power supply. The recovery sequence is as follows:

If at this stage no problems were observed, the recovery can be considered complete.

Possible failures and their elimination

Now we will consider the problems that may arise during the execution of the instructions, and offer options for their elimination.

The flash drive is not recognized
The most common reason for this error is that the drive is not properly prepared or is in the wrong slot. Also, hardware problems with the flash drive itself or the USB port cannot be ruled out - check the operability of both the media and the output to which you connect it.

The flash drive is recognized, but the firmware file is not visible on it
This is usually seen among users who incorrectly named the required file. Turn off the computer, then open the USB flash drive on another machine and check that the firmware name is entered correctly.

The computer does not respond in any way to the connection of the drive
If all USB connectors on the board are known to be working, this behavior indicates much more serious damage than the "flying" firmware - most likely, there is damage to the BIOS chip, and you will need to either replace the board or carry it for repair.

Conclusion

This concludes our usage guide. aSUS utilities CrashFree BIOS 3. As you can see, the procedure does not differ from a regular firmware update.

BIOS was created in 1975, its abbreviation stands for Basic Input / Output System, and its main function is to launch the operating system and hardware components of the PC. It also loads power and temperature management features. The firmware identifies, tests and launches major system components such as hDD, video card and keyboard.

Most modern computers store the BIOS on a ROM chip on the motherboard. If it crashed, then determining the model of the motherboard will help to restore the BIOS, as a rule. The restart of the firmware will depend on this.

BIOS recovery is a simple process that anyone can carry out on a PC if a serious problem arises with it and you need to return the settings to factory condition... Before restoring the BIOS, the act of zeroing the motherboard is performed, a process called Clear CMOS. It provides for the following actions:

• clearing parameters stored in BIOS ROM;
• return the PC to the neutral state from which it starts;
• eliminate crashes when starting the PC for the first time after assembly or after updating in the BIOS.

The main reasons for performing a firmware restore are:

1. Motherboard does not start after BIOS-specific settings are configured.
2. One of the most common reasons - manual setting random access memory on the motherboard. If a parameter from the many settings that RAM has is entered by mistake, the board will fail and the PC will not start.
3. Another of the most common reasons is overclocking. If the user increases the frequency while the Vcore is insufficient for the processor, it is very likely that the motherboard will not boot.

In order to reboot, you need a key typed on the keyboard. It is different for different models computer and is usually indicated on the screen when the PC starts up, for a short period of time. Before you restore the BIOS that has flown, you need to find out the key keys.

They can be: F1, F2, F10, F11, F12, Esc, or some other combination like "Control + Alt + Escape". If the user does not know the recovery key and does not see the indication on the screen, then the query for the phrase "computer brand + enter BIOS" should prompt a solution. The same answer is in the PC manual. After correctly typing the keys, the user will see the BIOS setup screen.

If the BIOS has crashed, but how to restore on a PC it, the user does not know, experts recommend running Clear CMOS. To do this, the first thing you need to find on the surface of the motherboard are three grouped contacts, nearby which are the phrases Clear CMOS or CLR_CMOS. It will be easier for the user to find the mode if he first reads the motherboard manual. These pins will have a jumper to close the contact between them. It should also be noted that there are those that have only two contacts, without any jumper.

The algorithm for executing the mode is as follows:

1. Turn off the computer.
2. Find the battery on the motherboard. This is a round battery, similar to an element from a wrist electronic clock, located on the surface of the board.
3. Carefully remove it from the socket where it is located.
4. Before restoring the BIOS, which has flown off, change the position of the jumper, which closes the circuit between the two contacts. If contacts 1 and 2 are initially closed, then set the position so that contacts 2 and 3 are closed.
5. Find a conductive metal surface and manually close the circuit between the two contacts. A flat head screwdriver is an excellent choice for this purpose.
6. After completing this step, leave the circuit closed for at least 30 seconds.
7. After this time, perform the same actions, but in reverse order.
8. If everything went right, the system will start with the default BIOS settings.

If the BIOS has flown to the PC, and how to restore, the user does not know and cannot guarantee the safety of the machine, then it is better to perform full reset firmware on the laptop.

The operation algorithm is as follows:

1. Turn on the computer and study the BIOS splash screen, which will appear at the very beginning and tell you which function key (F2 / F8) you need to press to access the configuration.
2. Press and hold this key until the setting screen appears.
3. If the opportunity to press in time is missed, the PC will continue to boot from Win as usual, and a reboot with repeating steps is required.
4. After successfully entering the BIOS setup screen, use the function and scroll keys to navigate the menus.
5. Find the "factory reset" option.
6. If Windows has crashed, restoring the BIOS, as a rule, will help to follow the instructions on the screen to go to the original configuration.
7. Confirm your choice and close the screen.
8. Since the BIOS is in ROM, it must have a constant power supply to store any changes that were made to it every time the computer was disconnected from the network. alternating current.
9. If it is not possible to return to the factory settings, disconnect power from the BIOS, it returns to its initial configuration... The process consists of disconnecting a small battery on the motherboard. In many laptops, the BIOS battery is easily accessible and is located at the bottom of the device.
10. It doesn't matter how the BIOS on the computer crashed, updating the SMOS of the motherboard will help to restore it correctly. This requires removing the battery and touching a metal object to ground it.
11. Next, remove all the screws that hold the battery cover.
12. They find the BIOS battery in the form of a small lithium construction, similar to a watch battery, remove it, being careful not to damage the adjacent circuits. Wait a minute for it to discharge and insert into place. Then, the starting procedure is repeated from the beginning.

The main problem when updating BIOS in Windows 10 can occur when trying to reboot. Sometimes the user cannot open the BIOS no matter how much he presses the key. This is because Windows does not restart the PC by default.

If Windows 10 has crashed, the following algorithm will tell you how to restore BIOS by using the key keys:

1. In order to be able to enter the BIOS, the first thing to do is to start booting the PC.
2. To turn off the computer, press "Alt + F4" on the desktop or use the "Start" menu. It should be borne in mind if the laptop uses the technology " quick launch", It is quite possible that the normal shutdown of the BIOS will not start. There are a number of preliminary steps to follow.
3. First, click on the "Start" menu and then select "Settings".
4. AT windows configuration move on to the last section titled Update and Security for similar recovery and troubleshooting configurations.
5. Click on the "Recovery" tab in the left pane, and then the "Restart now" button in the "Advanced Startup" section.
6. A menu will appear with a blue background, which is used to solve problems with Windows, and one of the options is to enter the BIOS.

If "Windows 10" has flown, how to restore the operating system through BIOS, users will be prompted by special tabs "Solve problems" and "Advanced options".

Maternal gigabyte boards includes functionality called "dual BIOS", which allows in the event of a failure to update a gigabyte of BIOS or loss of power during the process, to restore a defective reserve copy... It doesn't matter how the BIOS crashed, it will be possible to restore the work on Gigabyte dual only with the use of an update.

Updating BIOS gigabytes from Windows can be done in two ways:

• by preloading the BIOS from the motherboard;
• update BIOS from Gigabyte server so that the program looks for latest version.

If this needs to be done using the previous bIOS bootFor example, when there is no internet on the PC, download the above program and the BIOS version that is needed. The latter is recommended to hardware worked with the highest possible performance and stability.

You can make a backup copy, which is at the moment, to do this, click the "Save current BIOS to file" tab and indicate the route to save the file. As soon as the user has everything he needs, he starts the update by clicking on the "Update BIOS from file" tab, the program will ask you to search for the previously downloaded file.

Q-FLASH app

You can update from your own gigabyte BIOS, with an application called Q-FLASH built into it. Before starting, format usb into fat32 and unpack the BIOS inside. Insert into port USB before entering the PC. The utility offers 3 options: the first, which puts "Update BIOS from disk", the second - "Save BIOS to disk", and the third - "Exit Q-" to exit the application.

After the BIOS has flown, the use of a special utility will help to restore the functionality of the operating system step by step.

The algorithm of actions looks like this:

1. Select the usb that contains the bios file.
2. Select the BIOS version to enter and begin the update process.
3. Check for a new file inside usb.
4. The assistant asks, up to the version that is in usb, confirm "yes", and the process begins.
5. Make sure the process is done correctly.
6. They reboot, enter the BIOS and check that the version has been changed.

This process allows you to update the gigabyte BIOS to a higher or lower version. In addition, with Gigabyte's dual Bios system, you can be calm before possible failures, since they start the system from its backup copy.

You can restore the system without going into Windows 7. It often happens that after you have crashed "Windows 7", restore the system through the BIOS is the only way to restore the performance of the PC. The procedure will depend on the specific hardware installed on the machine. If the unit has a CD / DVD player, erase all discs from it. Then turn off the computer and external USB drives.

Recovery algorithm:

1. Turn on the PC and quickly press the F8 key on the keyboard. The Win logo should not be displayed. It is best to press F8 several times in a row, while starting the PC.
2. When the process goes well, a screen appears with a black background and white letters. Turn on advanced boot options by using the arrow keys to select the one that installs safe mode from command line, and confirm Enter on the keyboard to enter it.
3. After downloading a series of files, an MS-Dos console window opens with a black background and white letters. They register the command: rstrui.exe and press Enter on the keyboard.
4. Recovery Assistant starts, the user must follow all its instructions.

Surftec reinstalls all Lenovo systems to standard windows version 7 Professional, while newer systems are usually installed with Windows 8 or 10.

Windows 8 supports the newer, faster BIOS, UEFI, which provides additional security. For windows startup 7 this mode must be disabled. For a situation where the BIOS on a lenovo laptop has crashed, establishing the causes of the emergency will help to restore its performance.

If the user has reset the BIOS and the default features have been enabled, then Windows 7 most likely will not be able to start automatically. There may be other problems in the system, for example, not working wireless connection or old hardware drivers, which will also interfere with the normal recovery process.

1. They close the windows and make sure that the laptop is completely turned off, for this they go to the "Start" menu and select "Shut down".
2. Press the power button and then the F1 key every two seconds until the BIOS welcome screen appears.
3. The BIOS is navigated using the arrow keys on the keyboard. The left and right keys move between the top BIOS titles "Main", "Config", "Date / Time", "Security", "Startup" and "Restart".
4. The up and down arrows navigate the available options on each page.
5. The enter or back key will open the option with additional settings, then use the up and down arrows to highlight the desired option and the return and enter key.
6. Use the right arrow key on the keyboard to select the "Restart" screen.
7. Use the down arrow key to select OS Optimized Defaults.
8. Press the return or enter key, a pop-up window will appear.
9. Use the up and down arrow keys to select Disabled. The selected option is highlighted in bold and white text.
10. Use the up arrow once to select “Load Setup Defaults” and press the “Return” or “Enter” key.
11. Make sure "Yes" is selected using the left and right arrow keys, and then press the Enter key. The selected option is highlighted with a black background.
12. Press the F10 key and select "Yes" using the left and right arrow keys.
13. Press the return or enter key to select "Yes", now the machine will save the new settings and reboot.

AMI Biostar boot software

If the BIOS has flown, how to restore the biostar from the boot block floppy disk can be clarified in the technical documentation for the motherboard. But since this scheme is used for old modifications of computers or PCs operating in server mode, the instructions may have been lost, then you will have to look for the topic on the Internet.

This setting is standard function AMIBIOS8 kernel is enabled by default and allows the user to restore the BIOS image using a floppy disk without the need for additional utilities. Before restoring the biostar, if the BIOS has crashed, perform following instruction... Instructions for manually starting recovery of the boot block from a floppy disk are as follows:

1. Insert the floppy disk with the new BIOS file into the root directory of drive A. In most cases, the file should be named AMIBOOT.ROM. However, this filename may differ from one product to another. The user can clarify this information in the technical documentation of the motherboard.
2. Press and hold the keys while turning on the power until the floppy disk drive access light comes on, which may take a few seconds.
3. The keys are released and AMIBIOS emits a series of beep codes that indicate that the system BIOS file is being updated.
4. After the file is loaded, a progress dialog will be displayed on the screen.
5. After successfully programming the Flash ROM, the computer will restart.
6. The user should not interrupt the BIOS flashing process until it completes completely.
7. One of the functions of the BIOS AMI boot block is code to verify the integrity of the BIOS image in flash memory.
8. If there is a problem with the BIOS image in the boot block code, boot block recovery will automatically start. This condition will be indicated by a series of beep codes.

BIOS Recovery Boot Block is a special BIOS boot block with minimal initialization. The function is enabled to restore the firmware to successfully complete after a failure of the BIOS flashing process. The system provides hot keys "Fn + Esc", which enable the process of restoring a working system during BIOS POST. It is recommended to use the AC adapter and battery to use the function. When enabled, the BIOS will force you to enter a special block called the Boot Block.

Recovery steps should be taken using a USB stick:

1. The Crisis USB key is prepared in advance. It is created by running the Crisis Disk software on another Windows operating system.
2. Connect a USB disk.
3. Run the wincris.exe program to create the USB Crisis disk.
4. Click "Start" to start the process.
5. Select the "Quick Format" option for the disc and press "Start".
6. Follow the instructions on the screen to create a disc.
7. Copy the BIOS file KAYF0X64.fd to the root directory of the USB flash drive.
8. Connect the USB storage device to the USB port.
9. Press the "Fn + ESC" buttons, turn on the power.
10. The power button flashes orange once.
11. Press the power button to start the Crisis system mode.
12. After CRISIS completes, the system reboots with a working BIOS.

Acer reset options

If the user has forgotten the BIOS password for acer laptop, he will need to access the BIOS to make some hardware changes to the computer, which can be password protected. It's easy to reset it before logging into Acer.

The procedure for resetting the password via Acer eSettings is as follows:

1. Install the Acer Empowering Technology software.
2. Open the Start menu and select All Programs\u003e Empowering Technology\u003e Control from eSettings.
3. Click " BIOS passwords»On the screen footer.
4. Regain control using the Create or Delete options.
5. Reset Acer laptop password.

Removing it with a CMOS battery is a common way. This method involves the use of computer equipment, therefore, it is intended for users who know the PC device.

It doesn't matter how the BIOS crashed on the Acer laptop, you can restore the laptop using the firmware method:

1. Disconnect the power cable from the PC.
2. Remove the computer case with a screwdriver and find a flat, round and metal CMOS battery.
3. Examine how the latches hold it in order to properly eject the CMOS battery.
4. After extraction, they wait 30-40 seconds, insert the battery into place and restart the PC.
5. If everything went well, there should be no more password.

Thus, BIOS is a basic input-output system, an irreplaceable function of the operating system of hardware components, on the correct operation of which the reliability of the computer depends. He does not like frequent intervention in his settings, but nevertheless, a competent user needs to know how to work correctly with the system for all kinds of extreme cases.

If your ASUS device is implemented on a modern motherboard, then you can use the instruction How to flash ASUS BIOS (ASUS EZ Flash 2) (in this case, create bootable USB drive not required)

Preparatory stage:

1. First of all, we go to the ASUS website.
2. We select your product (laptop or motherboard), then the series and model, and then press the Enter key or the Search button.
3. The site will offer to choose an operating system, if possible, select the one you are using, if it is in the list.
4. Go to the BIOS section and download the latest BIOS version.
5. Download the utility for flashing BIOS - AFUDOS. This can be done on the same ASUS product page in the BIOS Utilities section. Or
6. Create a bootable DOS flash drive (optional - another way to create a bootable DOS flash drive)
7. I also recommend connecting the flashed device to an uninterruptible power supply (for a laptop - fully charge a serviceable battery), because in the event of a power failure during the firmware process, the device will have to be carried to a service center for recovery.

1. We open our bootable USB flash drive, write the afudos program (afudos.exe file) and the BIOS itself (example: p4c800b.rom file) to it.
2. Reboot and press F8 when the first picture appears on the monitor. We get to the quick launch menu and select our USB flash drive. Or at startup, press F2 for laptops or Del for desktop PCs, go to the Boot tab and put the USB flash drive in the first place, usually for this in the 1st item Boot Device you need to set the Removable Device, then press F10 and confirm that we want to save the changes in the settings.
3. The computer will boot from the flash drive, and will display an invitation to work C: \\\u003e on a black screen. (or another drive letter - it doesn't matter)
4. To start the firmware process, write afudos / ip4c800b.rom and press the Enter key. Running BIOS firmware
5. Note: Do not turn off the power or reboot the system during bIOS updates! This can cause serious damage to your system.
6. After completing the BIOS update, the utility will return to DOS. Remove the floppy disk (USB flash drive) and reboot the system to enter the BIOS menu. BIOS firmware completed
7. Go to BIOS and reset the settings to their original values.
