My laptop is a little over a year old and I noticed earlier in the week that battery life is still good but the computer is not reading it right. I tried letting the battery die down all the way then fully charging it back up but when I tun the computer on it says 47% even though its full. Within an hour it drops to <10% but and keeps giving me critical battery warnings. The problem is stays at 6/7% a few hours now (its a netbook and has good battery). Is there anyway to fix this?
