If you want to delete the password of your BIOS, this is unfortunately not possible. But in order to be able to use your PC again, you can reset the BIOS manually – and thus also the password.
Deleting or resetting the password of your BIOS
As mentioned above, the password cannot be deleted. But by opening the computer and a few specific actions, the password of your BIOS can be reset.
- First of all, you need to disconnect any power supply. In the case of a laptop, this also includes removing your battery.
- Press the power button to discharge the internal buffer circuits and capacitors. Now you can proceed with opening the housing of your PC.
- Before you do anything about the hardware, it is very important that you ground yourself. This is because the sensitive hardware can be damaged or even destroyed by electrostatic discharge. The subsequent troubleshooting becomes a torture.
- The next thing you need is the mainboard of your PC. There is a jumper on it that can trigger the reset of your BIOS. To do this, move this jumper by one pin. Leave the jumper in this state for about one to two minutes to be sure. Afterwards, move the jumper back to its original position.
- After that, the reset is done and you can reassemble and start your PC. The reset has restored all the factory settings.
- Alternatively, you can also remove the CMOS battery to cause a total lack of power to all components in the PC. About half an hour should be enough for your hardware to lose the stored password. Then you can put the CMOS battery back in and reassemble everything.
- If it is impossible or hardly possible for you to open the housing yourself, there is still the possibility of asking the manufacturer for a possible master password.
