Sometimes a computer owner is faced with the need to clean the system from various bugs that interfere with normal operation. This can be done by reinstalling the operating system, or using special utilities. But there is a method that has several undeniable advantages over them.
Resetting the settings to factory defaults will help restore the device to functionality in most cases, even if you cannot start the OS. This method is especially relevant for those who do not want to waste time reinstalling the OS.
When restoring factory settings, the OS will be reinstalled automatically. You will not need to enter the OS activation code again. That will be restored Windows version, which came with the laptop upon purchase.
By rolling back the BIOS, you will eliminate the problems listed above. In this article we will look at how to return a laptop to factory settings and restore its functionality. There are several methods, which we will take a closer look at.
The option to reset settings may be needed if:
What are the factory settings?
Factory parameters are set by the manufacturer for specific model computer or laptop. They store BIOS settings and computer configuration parameters. This information is located in the device's dynamic memory, which is called CMOS.
All factory settings take up very little space and are separately powered - from a small battery located on the motherboard. You can reset the laptop parameters without access to the BIOS. To do this, simply remove the battery, wait 30-40 seconds, and insert it again.
After the reset process is completed BIOS settings and the OS is reinstalled, you will receive the laptop in the same condition in which you bought it in the store.
It is worth noting that to successfully return the device to factory settings, in addition to CMOS, you need a Recover partition, which stores installation files and other necessary system information.

Where is Recovery located and its activation
A hidden partition on the hard drive that stores all the files needed to restore the system is called Recovery. It is created by default on all laptops, and is deleted or damaged in most cases as a result of incorrect user actions.
You can see where the hidden section is located:
There you can also see the size that Recovery occupies on the HDD. Typically this is 20-25 GB of system information and installation files.
If you have Toshiba laptop, then you probably already noticed that on drive D there is system folder, called HDD Recovery. It also stores the information necessary to reset the system, so it cannot be deleted.
Activating Recovery starts the process of resetting user BIOS changes, restoring factory settings, and reinstalling the OS and system programs and drivers.
To activate Recovery, press a specific hotkey combination. This will allow you to login system menu, where you can select several system recovery options. It should be remembered that each manufacturer has its own combination of hot keys; below we will look at the most popular ones.
Restoring settings using hotkeys
In order to return your laptop to factory settings, you should remember several hotkey combinations. When the system boots, press hot keys to access the menu BIOS Setup, from where you can start the process of restoring parameters.
Depending on the computer manufacturer, hot keys and their combinations differ:
- Toshiba - depending on the model F8, or 0, or Fn+0;
- Sony - F10;
- Acer – Alt and F10 at the same time;
- HP, LG and Lenovo – F11;
- Samsung – F4;
- Fujitsu - F8;
- ASUS – F9;
- Dell - both Ctrl and F11, but in some models F8;
- Packard Bell - F10. If you have Windows 8 installed, you can use the power button when you log in. You should hold down Shift and at the same time select the “Reboot” menu item;
- MSI – F3, and on some models F11.
How to reset a laptop to factory settings via BIOS
Using hot keys, you can roll back custom system changes and return the BIOS to factory settings.
On the black screen that appears, select sequentially:
- option "Running the recovery center" for Sony, or "Troubleshooting your computer" for Toshiba, or "System Recovery" for HP;
- menu item "Load Defaults BIOS".
Depending on the manufacturer, the option name may vary: "Load BIOS Setup Defaults", "Load Safe-Fail Defaults", but the words "Load" and "Default" will definitely be present.
Preparation
Prepare for a factory reset:
After you start the process of resetting the settings, the process of collecting information and preparing system files. This may take some time, so don't worry.
Recovery process
Once you start the recovery process, all actions will be performed automatically, without your participation. The computer may reboot if required by the installed software. During the process of resetting the settings, device drivers will be restored and standard system programs will be installed.
It is worth mentioning that it is not always possible to successfully reset the settings on a laptop. This is possible if:
What can you do if you deleted hidden Recovery section from hard? You'll have to search boot disk with settings or an image of a hidden partition for your laptop. They can be found on the Internet, and sometimes manufacturers offer to buy such disks for system recovery on official websites.
If there are no ready-made images for your laptop, you can ask the owners of a similar model on computer forums to create such an image for you. And to avoid such a situation, you can create your own bootable USB flash drive or a DVD for your laptop that you can keep on hand and use when necessary.
At the time of updating the BIOS, absolutely any and even the most insignificant error can disable and undermine the stability of your motherboard. For example, if, when updating the BIOS, you loaded the wrong firmware version, or at the most inopportune moment, the power supply was cut off, then the motherboard may stop working completely. It even happens that when updating the BIOS, you installed the latest firmware version, it may simply contain damaged files or errors and they will undoubtedly lead to unstable performance. This is why a so-called BIOS recovery is often required to return your system to full life.
A little about the principle BIOS operation BIOS, or otherwise “basic input/output system”, works like a regular universal driver. It can connect hardware and software parts with each other personal computer, providing the operating system with full communication with all parts and components system unit. Also, the BIOS is used for initialization and checking the configuration definition full load PC.
The motherboard has a special chip with flash memory, which is awarded the authority to store the BIOS, so it is this that is flashed. All motherboard manufacturers regularly post updated BIOS firmware, which every user can download so that they are free. You just need to know the motherboard model, manufacturer and type of BIOS itself. When flashing the BIOS of the motherboard, you can increase compatibility with the operation of new equipment and improve the operation and functionality of the board itself. However, there is no need to frequently flash the motherboard if the old BIOS version does not cause any problems. This action should only be used at those moments when you have reinstalled new processor or noticed any instability in the operation of the system, a frequently occurring “screen of death”. Next, I will give several utilities with which you can restore the BIOS yourself.
What to do if the computer takes a long time to turn off?
BIOS recovery via ASUS CrashFree BIOS
The famous company ASUS offers its users BIOS recovery using a built-in utility called ASUS CrashFree BIOS. which will allow the user to roll back the BIOS version if any problems arise when installing a new one. This utility easily reads the firmware file, which can be written to a laser medium, flash drive or flop drive, and then, automatically, installs it instead of the inoperative version. In order for you to fully use this utility and restore the BIOS, you need to download and then cut your old version firmware.

Also, before installation new version, you can copy the old version or, if you do not have such an opportunity, you can make a copy from a similar motherboard. Once you have found your firmware version, copy it along with the program onto one medium. After this, we insert our disk into the drive of a non-working PC and when the system boots, BIOS recovery begins immediately.
Restoring BIOS using ASUS BIOS Updater
In order to protect yourself from problems that may arise in the future, you can use another utility - ASUS BIOS Updater, which will help you create backup copy current BIOS version before the update operation. Format the USB flash drive to file system FAT 32 or FAT 16, then download and save the latest BIOS firmware and ASUS BIOS Updater utility on it.
Connect the USB flash drive to a free port on the computer and turn on the computer. While the computer is booting, press the “F8” button to call up the boot menu, in which select “CD-ROM”. Before doing this, you need to install a boot disk with the FreeDOS operating system into the drive. After loading the OS, in the command line, select the drive letter that is assigned to the flash drive, for example “d:” and press “Enter”. After which you can run the command to create a file in which the old BIOS will be saved - type and run “bupdater /o filename.rom”, where the correct name of the firmware file should be indicated. Well, not like that in cunning ways and certain utilities, we were able to restore the BIOS ourselves. As they say, the eyes are afraid, but the hands do. If you have any questions or suggestions regarding this article, leave them in your comments. In one of our articles you can also learn about BIOS, as well as how to enter the BIOS on Windows 10.

BIOS recovery ASUS K52D
Restoring BIOS to ASUS laptops K52D after unsuccessful firmware, as it turned out, is not a very difficult task. For this you will need a 1-2GB flash drive (this is already a rarity, yes), a laptop with a damaged BIOS (and otherwise functional), Internet, and patience.
The actual preparatory stage is as follows: 1) format the flash drive in FAT16 or simply FAT 2) download the latest one from the website available firmware(although ASUS lately likes to upload something semi-working) 3) write the firmware to a flash drive in several copies with different names (I also don’t understand which option worked): AMIBOOT.ROM, AMIBOOT.BIN, K22D.bin, K22D.rom 4) unplug the laptop from the outlet, unplug the battery, insert the flash drive, turn on the power and turn on the laptop by first pressing Ctrl+S or Ctrl+Home or Win+B. Although, again, according to all external signs, it responded to all buttons in the same way - by turning on the diode on the flash drive.
5) if the indicators are on, the flash drive is also active, then we try to wait. The laptop should come to life after a while. If it doesn’t come to life, then try the same thing again, but with a different key combination

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 it yourself mobile computer. 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, in some laptops, for example, Acer Aspire, there are 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.
