How to reset BIOS settings to default settings. BIOS default
BIOS by default BIOS:(Basic Input-Output System) basic system input/output, which is stored in the memory of the motherboard and is needed so that you and I can control the hardware that is installed on your computer. Many users experiment with the BIOS, try to set the settings they need, some need to boot from a CD-ROM to install the operating system, and those who want to boot from a flash drive, some have a hard drive that is not detected, and so on. And it often happens that there is simply no way to work with these changed settings, what to do then.
First of all, if you change settings in the BIOS, it would be better to write down all your actions. If problems arise with your computer, you can restore initial settings. But even if you got carried away during the work and, of course, did not write anything down, in any case, you can always return to the initial BIOS parameters and make the default settings specified by the manufacturer; for this you will have to use the Load Setup Defaults or Load Fail-Safe Defaults function. It will set the safest BIOS settings, which will be optimal for normal operation systems, and they will become the same as they were before your experiments, we will look at setting it up here.
So we are in the main BIOS window, then we need to go to the (Exit) tab, it is located from the (Boot) tab to the right after the (Tools) tab and is underlined in red. In it, using the arrows on your keyboard, select the Load Setup Defaults item, press Enter and go to the menu. Today, most desktop computers equipped Ami BIOS or AWARD BIOS, and in our article we will mainly look at these manufacturers. By the way, everything we describe can be used to configure another manufacturer, Phoenix SETUP BIOS, it is used mainly on laptops.
Ami BIOS parameter Load Setup Defaults.
If the window is different, then this is Award BIOS,
Here the parameter we need is called Load Fail-Safe Defaults, indicated by an arrow in the photo.
They both are configured almost identically. In Ami BIOS we need to go to the (Exit) tab, it is located from the (Boot) tab to the right after the (Tools) tab and is underlined in red. In it, using the arrows on your keyboard, select the Load Setup Defaults item, press Enter and go to the menu.
Load Setup Defaults means loading the settings (BIOS) by default, that is, they will become what they were before your experiments, select OK and the settings will be reset to default, remember this very required parameter, now don't forget to save your changes and exit BIOS menu.
I hope our article BIOS default settings helped you.
Those who like to tinker with the BIOS settings sometimes encounter situations where something doesn’t work right. For example, if you set incorrect parameters in the settings or update the BIOS incorrectly, then the correct work computer. This may manifest itself in unstable work system or even its complete failure (the computer simply will not turn on). And resetting the settings in BIOS will be the only option in in this case. And to reset everything BIOS settings to factory settings, you need to know how to reset the BIOS.
A little about BIOS
BIOS (Basic Input-Output System) is a basic input-output system, or simply put, a program that is stored in
ROM (read-only memory) chip and launches and configures all equipment even before loading the operating system. BIOS is located on motherboard and is the code responsible for the operation of all devices in the computer (or laptop). The better this code, the faster the computer will work. All basic parameters equipment is stored here. Although some parameters are set during the installation of the operating system. When turned on computer BIOS within a few seconds it tests all devices for functionality and, if everything is normal, transfers control to another program that is already loading the operating system. In the BIOS you can change many settings, including overclocking the processor or video card. In fact, unsuccessful overclocking of a video card or processor may be the very reason why you need to reset the BIOS settings.
It's quite simple to do. To do this, you will need to restart the computer (or turn it on if it was turned off before), and as soon as the first inscriptions appear, you need to press the key. Which one exactly depends on the model of the installed motherboard. Most often these are the “Del”, “F2” or “F10” buttons. You can find out which key activates the BIOS call when the computer boots at the bottom of the screen (before the OS loads).
As a rule, calling the BIOS may be necessary in case (this is one of the reasons). To install everything correctly, you need to completely clean it hard drive, but this can only be done through the BIOS.
Why reset BIOS settings?
There can be many reasons why you need to reset the BIOS settings. For example, the user was too overzealous with tuning the computer's performance. Namely: overclocked the processor or video card to critical levels. For security reasons, the computer now does not want to turn on. It informs the user that the device temperature is too high and turns off. Of course, some models can automatically restore factory settings, but this is not always the case. Most often, the user has to perform this procedure independently.
Another reason why you have to think about resetting the BIOS is failed update. If mistakenly (or out of ignorance) there was one that does not fit the motherboard or BIOS version, then the computer will start to “fever”. This situation can only be corrected by resetting the BIOS.
A fairly common reason for resetting the BIOS is also resetting the password. That is, if when you turn on the computer, the system asks for a password, and the new owner of the computer, of course, does not know it, then you have to reset the settings in the BIOS.
Other reasons may be:
- the computer does not respond to pressing the power button (does not turn on);
- the computer turns on, but makes some sounds and does not load the operating system;
- The computer constantly freezes, reboots, etc.
How to reset BIOS settings?
There are 3 ways to restore BIOS settings to default:
- from the BIOS menu;
- using a jumper;
- using a battery.
Laptop owners should take into account one fact: in order to reset the BIOS using the last 2 methods, you will need to disassemble the laptop, i.e. you will lose the warranty on it (if it is still valid). To solve this problem, it is better to contact specialists at the service center.
So, the first method is to restore the default settings from the BIOS menu. First you need to go into the BIOS. This can be done using the “Del”, “F1”, “F2”, “F10” buttons (depending on the motherboard model). If you cannot enter the BIOS due to set password or various errors, then this option is not suitable for you.
You can reset the BIOS settings to factory settings from the exit menu BIOS Setup— the required parameter is called “Load Optimal Defaults”
Then you need to find the option to restore default settings. The position and name of this option may vary depending on the motherboard model. Most often this item is called “Reset to Default”, “Factory Default”, “Setup Defaults” or something like that. This item can be located either in one of the tabs or next to the navigation buttons. You must select this option and confirm that you really want to reset all settings to default. If for some reason you do not have this item (or you did not find it), then you can use another method.
After this you need to save the changes. When exiting the BIOS, the system will ask if you need to save the changes. After confirmation, the computer will restart automatically. If you need to install certain settings, then you need to go into the BIOS again, make all the necessary changes and restart the computer again.
Method two is to reset the BIOS using a jumper. First you need to turn off the computer using the corresponding button in operating system. Then you need to find the switch on the back panel system unit(if it is there) and switch it to position “O” (off). If there is no such switch, then you just need to unplug the computer from the outlet.
After this, you need to open the case of the system unit. The goal is to get to the motherboard. You need to be very careful when working with computer components, especially avoiding electrostatic discharge, as it can damage some parts of the computer. It is advisable to ground yourself before touching the components.
Next you need to find a 3-pin jumper on the motherboard, usually located next to the CMOS battery. The jumper will be installed on 2 pins (there are 3 in total). It may be labeled CLR, Clear, Clear CMOS, etc. It is advisable to look through the documentation for the motherboard to make it easier to find the jumper.
Then you need to move this jumper to the other 2 pins. For example, if it was on the 1st and 2nd pins, now you need to move it to the 2nd and 3rd. To avoid damaging the pins, you need to pull out the jumper in a vertical position.
After this, you need to press and hold the computer's power button for about 10-15 seconds. Since the computer is turned off, nothing should happen. This will discharge the remaining voltage on the capacitors and reset the BIOS settings. Next, you need to return the jumper to its original position, and then close the system unit case.
Now you can plug in your computer and press the power button. If necessary, you can go into the BIOS to change the settings.
The last method is to restore the BIOS settings to default using a CMOS battery. It is necessary to turn off the computer again, switch the switch to the “O” (off) position and unplug the cord from the outlet. Then you need to open the case of the system unit; to work you will need access to the motherboard. You can get to the battery on your laptop by opening the panel on the bottom of the laptop. If there is no such panel, then you will have to get to the battery using special tools.
After this, you need to remove the battery. She may be in different places(depending on the motherboard), but most often located next to the PCI inputs. Next, you need to reset the BIOS by holding the power button for 10-15 seconds. Then you need to install the battery, close the case and connect the computer to an outlet.
These are the ways you can reset the BIOS. If such manipulations are quite difficult for you, it is better to use the services of a service center.
We switched something wrong in the BIOS or UEFI and as a result, problems arose in the operation of the computer. You messed up something in the settings and don’t know how to return them to default. Or maybe the computer does not start at all after changes to the BIOS. Let's look at how you can reset the settings to default values.
BIOS have a direct impact on the operation of the computer and its individual components. Sometimes there are times when you need to change something - switch the drive operating mode, adjust processor settings, and the like. It may happen that we configure something incorrectly and don’t know how to reset it to its original values. It even happens that the computer may not boot at all - what to do in this situation?
Method 1: Reset settings via BIOS/UEFI
The best option is to reset the BIOS to factory settings. Then all the changes you made will be reset and everything will work as before. There are several ways to do this. If the computer turns on, then you can go into the BIOS and restore the default settings. Otherwise, if you cannot enter the BIOS, you will have to edit it manually.
If the computer turns on, the first screen will display information about the key through which you can Setup. As a rule, these are the Del or F2 keys.
These functions are responsible for restoring default values. Launch one of them, and then exit the BIOS by clicking on “Save and restart”.
If you have a slightly different BIOS window, pay attention to options like “Load BIOS defaults”, “Reset to default settings” or something similar. Then save the changes and restart the BIOS.
However, the situation with recovery is the same in the case of UEFI, only the graphic window is different, which is more extensive. We go to the main UEFI window and look for the option to reset to factory values.
Typically this option is located on the “Exit” tab or is displayed when exiting UEFI - to reset the settings to factory settings, click on “Load UEFI default settings” and save them before leaving the configuration.
Method 2: Reset using a jumper on the motherboard
If you cannot enter the BIOS on desktop computer, then can be reset using the CMOS jumper on the motherboard. This is used to reset to default values.
Find the jumper on the motherboard designed to reset the BIOS. It is usually labeled as Clear, CLR, CLRCMOS or something similar. With the computer turned off, it needs to be reinstalled from contacts 1-2 to 2-3 for about a minute. After this, the settings will be reset.
Another way to reset the settings to factory settings is to remove the battery from the socket on the motherboard. It is responsible for saving BIOS settings and system clock. Remove it for a few seconds and insert it back, which will reset the settings to default values.
At the dawn of appearance computer equipment Most users were wary of such a technical innovation. In case of problems, always seek help from qualified specialists. Time has passed, and there are significantly more advanced users. There are even more people willing to experiment with their PC, changing some settings in an attempt to increase performance.
Because of incorrect settings the system may not boot
However, as a result of unprofessional actions, mistakes can be made that lead to serious problems, as a result of which it becomes necessary to learn how to reset the BIOS settings.
BIOS is special program, stored in the ROM chip. It is the BIOS that is responsible for starting the installed hardware. When turning on the PC, each user can hear a characteristic sound, after which the operating system starts.
Experienced owners confirm that this is how the BIOS tests devices and determines their performance. If a problem occurs, it is the BIOS that does not allow the operating system to boot, preventing more serious problems from occurring.
Reasons for resetting the BIOS
Since the BIOS is a kind of program, if desired, PC owners can make changes to its settings if they want to overclock the video card or the processor itself. In this regard, the most common reason why you have to reset the BIOS is overclocking the video card.
By overclocking a video card or processor, the user wants to increase the performance of the electronic computer. However, having set critical parameters for the above devices, the computer will once again stop booting, since the BIOS receives information about exceeding temperature regime specific device.
And due to the fact that the BIOS considers this to be the highest risk, it prevents the operating system from loading further.
There is another reason that provokes incorrect BIOS operation. Like any program installed on a PC, the BIOS can also be updated. However, it may happen that the update files were initially downloaded incorrectly because they were intended for a different motherboard. By making such an illiterate update, the owner of a smart car himself provokes bad job computer.
Setting a password, which is subsequently safely forgotten, also directs the user to reset the BIOS.
Experts can name several more reasons why you have to think that the BIOS is not working correctly. When nothing happens when you press the power button, unusual sounds can only be made; If your computer reboots spontaneously or experiences frequent freezes, it is useful to reset the BIOS to factory settings on your PC.
How to reset BIOS
You can reset the BIOS in two ways, conventionally divided into technical and software.
Soft reset
It is quite possible to return the factory default settings by going to the BIOS menu. You can log in the moment you turn on your computer. When only the first inscriptions appear on the screen, the user must quickly press a certain button. This could be "F2", "F10" or "Del". In some cases, the button may be different; by reading the instructions for the motherboard, you can find out which specific button is suitable for this model of electronic computer.
Clicking correct button, the user enters the BIOS menu, where you should find a parameter such as Load Optimal Defaults or something similar, since different models There may be different names for the specified parameter.
After selecting this value, the BIOS will ask you to confirm the user's desire to reset the BIOS to factory settings. By pressing “F10”, the computer will reboot, after which the BIOS will be completely reset and the settings will return to their default state.
Resetting the factory default settings using this method is not difficult, but this method comes with both an advantage and a disadvantage. The advantage is that there is no need to disassemble the computer, violating the integrity of the warranty seal. But the disadvantage is that if the reason for resetting the settings is a password that is hopelessly forgotten, then this method will be ineffective, you will have to use another method.
Technical reset
Having figured out how to reset BIOS settings to default programmatically, it would be a good idea to familiarize yourself with other options.
Initially, you should turn off the power to the smart machine, unplug the cord from the outlet, making sure that the equipment is completely de-energized.
Next you will need to remove the cover of the system unit and find the place where it is installed CMOS battery. Next to it it is easy to find a jumper consisting of three contacts and signed something like CLR, Clear, Clear CMOS. The jumper installed on this jumper occupies the first and second positions, the third remains free.
Now, wanting to understand how to reset the BIOS to factory settings, you need to carefully remove the jumper and also carefully insert it into the jumper again, but in the second and third positions.
