Remove CMOS password from a desktop computer

A client added a system password to his system via the CMOS Setup so the computer would ask for it every time the computer is switched on.
The only problem....
He forgot what it was ,now the quickest way to resolve this is to short or reset the CMOS Setup.
This is done by opening the computer box .
Once open find and locate the battery , we have to options here.
1: We can remove the battery and leave it out(with the power mains unplugged) for about 10 minutes .
2:Short the CMOS by jumpering two of the three pins(some boards only have two pins) next to the battery by placing a jumper on top of them for about ten seconds.
This is illustrated in your motherboards documentation.

Option one is the easiest one especially if you are a beginner.
