I purchased lenova g560 laptop. Battery is not
The problem is likely, as you might have guessed, with the computer's battery. If the computer is stock from Lenovo, I would first go about contacting them; I'm sure they would be happy to replace the battery free of charge if it's really as bad as you say it is. If not, you've got much more of a problem on your hands. While disassembling and fixing a battery yourself is occasionally possible, it is nonetheless NEVER recommended, not to mention this is not one of those times when it's likely to be possible. The structure of a lithium ion battery is actually relatively complex; it's hard to know exactly what's wrong, and if you don't manage to injure yourself in the process of fixing it, there's a high chance the battery would cease working entirely after you got it back together.
So, unfortunately, it looks like you're going to need a new battery. I know it sucks, but I seriously don't recommend trying to fix it yourself.
Also: If the battery isn't integrated into the laptop, you may be able to buy a new standalone battery. If it is, that may be difficult, if not impossible. If you can find a new integrated battery online, replacing the old one on your own is not out of the question, but there may be soldering involved. As long as you're comfortable with that.
Anyway, good luck. If anything was unclear, I'd be happy to make it not so, just give the word. ;-)
