have forgotten the password of your BIOS or you never knew it, whatever
may be the case is. Sometimes it becomes necessary to access the BIOS to
change system settings.

battery for few seconds.A computer uses this battery to remember its
settings and date & time when your computer is turned off. The CMOS
battery is the reason why you always get the correct date and time
whenever you restart your PC.
When you remove it from your CPU the computer will forget all the
settings which includes BIOS password too. So to reset/ remove your BIOS
password you just have to remove this battery once and then put it back
after few seconds.
