Answer 1

I'm not sure about the CMOS battery being dead being the cause of your problem.



the CMOS battery saves BIOS settings and the computer clock. It should not affect the hardware such that the battery does not charge.



If there is no charge light, it could be that your power adapter is damaged. If your computer will not charge does it still power on when connected to the mains with the power adapter? If so this would indicate a dead battery (not CMOS battery) and you should get a new one. Otherwise its most likely your charger/mains adapter that is broken!



You can also try plugging the laptop in to the mains power with the battery removed and see if that works (indicative of a dead battery if it does work)



For the record, a CMOS battery is a tiny button battery around the size of a coin. It is not the main laptop battery that you can easily unclip from the base of the laptop. It is not rechargeable.
