I just bought Asus Refurnished Netbook. For some reason it is taking an eternity for the first time charge. I have already plugged in for 3 hours and still it does not even open and shows LOW battery. Any ideas?
The most likely explanation is that the battery is dead. Laptop batteries (usually LiIon rechargeables) only last for about three years under ideal conditions, and can die in a matter of months.
It's also possible that the recharging mechanism has failed, but much less likely. Your best bet is to buy a new battery (which you most likely need anyway). If it still fails to charge, make a warranty claim for your netbook.
For a new battery, http://superuser.com/questions/152133/anyone-have-any-experience-with-bargain-laptop-batteries might be interesting.
