Basic settings regarding the operation of equipment and accessories are stored in the BIOS. You can get to this menu when you boot your computer or laptop. Usually, you need to hold the Del key while turning on the PC. Notebooks, as well as other brand assemblies, may have a different key. For example, there are options with F1, F2, F10. In any case, the key can be indicated on the loading screen, as well as in the instructions. In addition, it is worth looking for information on the official website of the manufacturer.
Resetting is required if you did something wrong and the computer does not start or is unstable. Often this happens when components are improperly dispersed. For example, you can try resetting the BIOS if the computer does not boot after changing any settings. And even when the system starts normally, errors and crashes to the blue screen can occur under load.
Moreover, by resetting the BIOS, you can remove the previously set password if you forget it. This refers to the password set specifically in the BIOS, and not in Windows.
What happens if you reset the BIOS
Simply put, when you reset the BIOS, nothing bad will happen. However, you need to understand that the settings will return to the factory state, which may affect the operation of the entire system. For example, you will lose the overclocking of components. This includes at least the frequency of the processor and RAM.
How to reset BIOS
There are many ways to reset the BIOS, the easiest of which is software. This is done from the settings and therefore the computer should turn on. Also, this method will not work if there is a password and you do not remember it. Depending on the BIOS version, the name of the item in the settings may differ. Therefore, you should at least be a little familiar with how this works. You need to search for items with names: Load Optimized Defaults, Load Setup Defaults.
In addition, you can reset the settings in a physical way. First of all, and it is much simpler, you should remove the battery power memory to store settings. This same battery allows the computer to display the correct time.
It is located on the motherboard both in a stationary computer and on a laptop. In the latter case, you have to disassemble the laptop, which may void your warranty. The same applies to branded desktops, if the warranty seal is on the case, then you can not open it.
Before removing the battery, disconnect the system unit, remove the laptop battery. Remove the battery and wait a few minutes before returning it to its place. Please note that the battery may be non-removable.
Jumper to reset
Another way is connected with a special jumper located on the motherboard. Before performing the operation, be sure to turn off the power supply, using the switch on its case. In addition, the battery is also worth removing.
Typically, a jumper is located next to the battery. There is no standard name for it. Designations can be: CLRTC, Clear CMOS, Reset CMOS, as well as various combinations and abbreviations of these words. Physically, the jumper looks like two or three-pin contacts. In the first case, they just need to be closed, for example, with a screwdriver. However, it is better to do this with the so-called jumper. It can be taken from another place on the motherboard, and put back after use. In the second case, the jumper is already present and connects two of the three contacts. It needs to be rearranged to the second position.
Keep the contacts closed for 10-15 seconds and then put everything back. If this option does not work, then with the contacts closed, hold down the power button on the case and hold it for the same 10-15 seconds. After that, you may need to leave the board in this state for 15 minutes.
Also on the motherboard, there may be a separate button to reset the settings. If it is present, then fiddling with jumpers is no longer necessary. It will be enough to hold it for 5-10 seconds with the power off.
