Uefi bios how to reset to factory settings. Restoring BIOS to factory settings
If your computer is unstable, a few tips on how to reset the BIOS may help. Problems arise as a result of incorrect BIOS settings or software failures. Let’s conditionally divide the zeroing procedure into two approaches depending on the problem: software and manual.
In the CMOS settings, find the item responsible for resetting the settings to default. It's called Load defaults BIOS, Load fail-safe defaults or something similar. It is located in a separate menu item or is always displayed in the right, lower part of the help window. It all depends on whether it is AMI or AWARD, which differ in appearance, name and location of menu items.
Once you have found this option, press the enter function key or F5, F6, F9, F11, F12. Next you will be asked to confirm the changes, enter the Y key or select OK and press ENTER.
When you have completed all the steps, be sure to save the changes. The save and exit item and the F10 key are responsible for this. The computer will restart and the settings will take effect.
There are situations when crashes occur immediately after turning on the computer. Therefore there is no possibility reset BIOS settings. There are a number of alternative actions that are considered manual.
The recommendations described below are universal. Suitable for motherboards such as asus, asrock, gigabyte. They are similar in architecture, but differ in the arrangement of elements. Next, let's look at what elements we need.
We kindly request that before performing the steps described below, it is recommended to study the documentation of the motherboard. This will protect you from unwanted consequences. You will be better oriented in your actions.
1 way. Be sure to unplug the computer from the outlet. When the PC is connected to the network, a small replenishment of energy also occurs, which will prevent you from resetting the BIOS.
Remove the side cover. Carefully inspect the motherboard. Here you will need to find contacts closed by a jumper. Next to which it says Clear_CMOS, CLR_CMOS, CCMOS or in another way, more details in the description of your board.
There are 3 contacts, the first two of which are closed by a jumper. Place the jumper on pins 2-3 for 15 seconds, then switch the jumper back.
If there are only two contacts and they do not have a jumper, short them with a metal object, such as a screwdriver.
Method 2. If you have a modern motherboard, it may be equipped with a special button for reset BIOS, which is signed as CLR CMOS. Find and hold it for a few seconds to reset the settings to factory settings.
3 way. Not a very reliable method. It is necessary to remove the CMOS battery for at least 10 minutes, or even more. That is why this method may not bring the desired result. Who wants to wait several hours? Sometimes it takes so long to reset the parameters.
After waiting, you need to insert the battery back and start the computer.
It also happens that owners are ready to throw away their components. I want to warn you against hasty conclusions. First, conduct a thorough diagnosis of your hardware. Often problems lie not in the breakdown of individual parts, but in software failures.
In practice, it happened that the computer started, but there was nothing except a black screen. The gradual replacement of components was not successful. The last thing that came to mind try resetting the BIOS. It really helped.
Reset BIOS settings possible in three ways:
Note: BIOS models vary and therefore your BIOS may look different.
In the window that appears warning that the settings will be reset, select YES.
All BIOS settings are reset.
Reset BIOS settings. Method 2
Every computer has a battery () that constantly supplies voltage in order for the computer to BIOS settings were not reset.
What should be done:
1. Turn off your computer.
2. Disconnect the computer's power cord.
3. Remove the cover of the system unit.
4. Remove the BIOS battery.
5. Close the “+” and “-” contacts of the battery socket.
6. Wait 10 minutes.
7. Reinsert the battery.
8. Assemble the computer system unit.
9. Connect all wires.
10. Turn on the computer.
Bios settings have been reset.
How to reset bios. Method 3
Some motherboards have a special jumper that can be used to reset the BIOS settings. Called a jumper CLEAR_CMOS (reset BIOS). It is located next to the BIOS battery:
In order to reset the BIOS settings, you need to move the jumper to the position 1-2 :
Then wait 10 seconds and return the jumper back to position 2-3 .
Greetings!
BOIS stores information and manages the underlying hardware installed on your computer. The BIOS is also responsible for the correctness of the time displayed in the operating system.
Why reset BIOS settings
Resetting the BIOS settings to their original settings may be necessary in the following situations:
1) You have installed some additional equipment on your PC, but it refuses to be detected by the operating system, or problems arise with its operation: the equipment disappears from the system from time to time, the system freezes, etc.
2) In an attempt to overclock your computer, you have set parameters in the BIOS that are not actually supported by the hardware installed in your PC. As a result, the computer stopped turning on altogether.
3) You have updated the BIOS, and in this situation it is recommended to reset the settings.
4) There is a need to reset the password that is requested when you turn on the computer (before the installed operating system actually loads).
This material will describe in detail and demonstrate with specific examples how to reset the BIOS settings to default (default) on a personal computer and laptop. We will look at resetting the settings both from the BIOS itself and by directly switching the contact/battery on the computer motherboard, which powers the BIOS chip and prevents you from “forgetting” the saved settings.
Resetting the BIOS through the corresponding menu item
The simplest and most logical way to reset BIOS settings is to use the menu item that is available in the settings of the BIOS itself.
It should be noted that this item is available in almost all versions and variants of BIOS, however its name and location may vary.
To orient you, I will show with a specific example the location of this item in a standard BOIS.
To enter the BIOS settings you need straightaway after turning on (even before the operating system itself boots), press the key several times Del on the keyboard of a personal (stationary) computer, or another key if it is a laptop. The key most often used to enter the BIOS on laptops is F2.
In the once popular and widely used version of the BIOS, this item was located in the main menu:
Load Fail-Safe Defaults- reset BIOS parameters and settings to default. In this mode, all computer components will undergo a full test. It is recommended to use it before installing the operating system and if you suspect that some component is working intermittently, for example, a RAM stick.
Load Optimized Defaults- if you select this item, the BIOS settings and parameters will also be reset, but with a focus on optimization. In this mode, some components will undergo a “reduced” test, which will make the computer boot faster.
If we talk about laptops, then everything is somewhat more complicated. In them, the BIOS menu interface can be greatly redesigned and stylized to match the company’s brand.
For example, in an HP laptop the BIOS looks like this. Here, resetting the settings is carried out by selecting the item Restore Defaults.
The name of the item that resets BIOS settings may be different, namely: Load Setup Defaults, Load Optimized Defaults, Reset to Default, Factory Default, Setup Defaults and consonant. The location may also differ; most often this item is located in the tab Exit.
Based on the above, you will need to find this item in your BIOS version (including UEFI) and click on it. Navigation in the BIOS is carried out using keys arrows, and select with the key Enter.
After resetting the settings, the computer will either restart or you will need to exit the BIOS with the settings that were reset to the default option saved.
If you do not have access to the BIOS due to a password set, or the computer refuses to turn on at all after “experimenting” with the BIOS settings (optionally, in an attempt to overclock the computer), then the following method of resetting the settings will suit you.
Resetting the BIOS via a jumper on the motherboard
Most computer motherboards have jumpers that physically consist of pins and, if necessary, are shorted using attachments (jumpers). By closing/opening certain jumpers, the configuration of certain PC parameters is carried out.
By closing the jumper that relates to the BIOS, the settings will be reset to the default option.
To reset the BIOS using a jumper, do the following:
Disconnect the computer from the electrical outlet by unplugging the cord from the outlet. After which you need to arm yourself with a screwdriver and unscrew the screws that hold the side cover of the computer.
Having gained access inside, you will need to find a jumper on the motherboard located there, which is responsible for resetting the BIOS settings and parameters. In most cases, this jumper is located near the battery, which powers the BIOS and prevents you from forgetting the settings.
As a guide, the jumper is often labeled accordingly: BIOS RESET, CMOS RESET, CLEAR CMOS, and the text can be abbreviated, for example, CLR_CMOS.
The jumper itself can consist of two or three pins. If there are three pins, then move the jumper to the next pair of pins, and if there are two, then you should borrow a jumper from another place on the motherboard. Just before borrowing a jumper, remember, or better yet, take a photo of its original position.
After this, you need to hold the power button for about 10 seconds. The computer, of course, will not turn on because... completely de-energized, this procedure is simply necessary to reset the BIOS settings.
Having done this, return the jumper to its original position, and then put and screw back the computer cover, connect the power.
Done, the BIOS has been reset. Now you can configure the BIOS settings again, or use those that were set by default.
Method for resetting BIOS with removing the battery
The BIOS reset jumper is in most cases located next to the battery. This is due to the fact that the chip in which the BIOS settings are stored is not non-volatile. This battery powers the BIOS, allowing you to save user-specified settings, as well as maintain the operation of the built-in clock during periods when the computer is de-energized.
After pulling the latch, carefully remove the battery for a few minutes, and then return it to its place - the BIOS settings and parameters will be reset.
It should be noted that in rare cases the battery is not removable. Take this fact into account if you see that the battery is very firmly seated in the slot.
Brief summary
Now you know in what cases you should resort to resetting the BIOS, and how this can be done. The first method is universal, while the second and third are more suitable for stationary personal computers. Laptops also have a battery that powers the BIOS, but getting to it is often much more difficult.
If after reading the material you still have questions, do not hesitate to put them in the comments.
Working with the BIOS requires great care, since incorrect settings lead to the computer no longer turning on or correctly detecting connected equipment. You can reset BIOS settings using three proven reset methods on your PC and laptop.
Reset in BIOS settings
If you manage to get into the interface of the basic I/O system, then there is still a chance to reset the BIOS settings through the corresponding item in the “Exit” section. This is one of the simplest options that does not require opening the computer system unit. So, to restore the BIOS and return the default settings, follow these steps:
This method works on a laptop and is suitable for a computer. After rebooting, the BIOS settings will be set to default. All changes made by the user after purchasing the computer will be canceled.
Jumper reset
The first method works if you have access to the BIOS. To reset the BIOS settings to the factory state if you have forgotten the password, you will have to disassemble the system unit and use a mechanical jumper, changing the position of which interrupts the supply of current to the CMOS battery. The battery is responsible for storing BIOS settings, so if you temporarily turn off the power or remove it, the parameters will be reset to factory settings.
To completely discharge the remaining voltage, hold down the power button of the system unit for 10-15 seconds. The computer is de-energized, so nothing will happen. Then return the jumper to its original position and assemble the system unit. Factory settings have been installed, now all parameters in the BIOS are set to default.
Removing the CMOS Battery
Speaking of the jumper, we have already mentioned the CMOS battery, which is responsible for storing BIOS settings. Accordingly, if you remove it from the motherboard and then insert it back, you can restore the parameters that were set by default. The algorithm of actions is the same as when using a jumper.
After resetting the settings, you need to reinsert the battery and reassemble the system unit. After turning on the computer, there will no longer be any password on the BIOS, and all parameters will return to the factory state.
Reset on laptop
While it is quite easy to disassemble the system unit, you may encounter some difficulties when resetting the BIOS on a laptop. It's good if you can go into the BIOS and restore the default settings by selecting the appropriate mode in the “Exit” section. If a password is set on the BIOS, you will have to disassemble the laptop. Turn the laptop over so the back is facing you. Look to see if there is a small hole on the laptop labeled "CMOS". 
If found, insert something sharp into the hole - for example, a paperclip. Wait for 30 seconds to reset the BIOS settings on your laptop. If there is no hole, you will have to remove the back cover and look on the motherboard for the CMOS battery or JCMOS pins.
- Disconnect the laptop from the network, disconnect the connected devices (mouse, speakers), remove the battery.
- Remove the back cover (on some models it is enough to remove the protection of the RAM and hard drive).
- Remove the RAM sticks and hard drive.
Under the RAM strips there should be two contacts that are labeled “JCMOS”. They need to be closed with a screwdriver. 
BIOS is a separate firmware built into the motherboard, which is responsible for a fairly wide range of tasks: it determines some computer settings, controls connected devices, checks the system for functionality, starts the operating system, and so on. If, for example, the BIOS settings were seriously changed as a result of careless actions, the reset procedure will help solve the problem.
Resetting the settings allows you to return the BIOS to its factory state. This procedure will be useful in cases where the computer does not work correctly, refuses to start the operating system and exhibits many other problems with its functioning.
Resetting BIOS settings
Fortunately, there are three options for resetting the BIOS, each of which can be useful in one situation or another.
Method 1: Perform a reset through settings
This method is the easiest to implement, but it may not always help, because if the computer refuses to enter the BIOS, you will have to use one of the methods given below.
In older versions of the BIOS, you will need to find the section that mentions the word "Defaults", for example, this item may be called "Load Optimized Defaults"(performing a reset to optimized settings) or "Load Fail-Safe Defaults"(performing a factory reset to fix computer problems). Having found the required item, select it, and then confirm your intention to start the procedure.
In more recent BIOS versions, which are usually found on laptops, the required reset item may be located in the exit section, that is "Exit". As a rule, this item is called "Load Setup Defaults".
And finally, in modern versions of BIOS UEFI which can be controlled not only using the keyboard, but also using the mouse, you should find the item "Load Defaults", which can also be located in the section "Exit" or "Save and Exit".
Method 2: Perform a reset using a jumper
Another method provided for resetting the BIOS, which involves opening the system unit in order to gain access to the motherboard.
Method 3: Perform a reset using a battery
There is a special battery on the motherboard that stores the BIOS settings. Removing and reinstalling this battery will allow you to reset all parameters to factory settings.
Please note that some motherboards are equipped with non-removable batteries. If the battery does not have a latch, you should not “rip out” the battery - this method simply does not suit you.
All three methods are effective. Which one to choose is up to you, based on the state of your computer and your capabilities.
