I don't think u need to do that...just remove it first and place it back firmly....it happened with me too once...was able to solve it by the same...

@pkkumarcool, its advisable to replace the battery, it cost some 20-25 bucks

^ you can measure the current voltage or the CMOS battery using a a voltmeter or a multimeter.

Note that the voltage must be >2.x V to work properly

if replacing the battery does not work then probably CMOS RTC chip is not working u need to RMA the MB

^^ Eh!
FYI: I guess it was your first time. You need to replace the battery once every 2-3 years. Matter of fact.
