How to Reset Bios



The CMOS is a small RAM that stores the basic configuration of your computer. This memory is volatile, meaning that once it is no longer supplied with electricity, it loses its data. That is why a battery constantly feeds the CMOS chip.

  1. Clear CMOS by removing the battery
  • Turn off your computer completely
  • Find the CMOS battery
Remove the battery for two or three minutes, then return it to its place. All parameters of Bios will be deleted. It is possible that a message (Checksum Error) appears at the start of your system. You can simply try to restart. If the message persists, load the default settings of your Bios (Press Del, F1 or F2 to enter Bios setup and press “Load Optimized Defaults”).

       2. Clear CMOS using the jumper (clear jumper)
  • Turn off your computer completely
  • Then look for the clear jumper which is located on the motherboard as shown in the picture below:





Just remove the jumper from pin 1 and 2 and place it on pin 2 and 3, wait for two or three minutes, then return the jumper to its original position. All parameters of Bios will be deleted. It is possible that a message “Checksum Error” appears at the start of your system. You can simply try to restart. If the message persists, load the default settings of your Bios (Press Del, F1 or F2 to enter Bios setup and press “Load Optimized Defaults”).
