Hello there! several years ago I bought this laptop, it is an hp G62-229WM, Serial # is CNF02101TF Product # is WQ843U#ABA.
The battery completely died, so I bought a replacement battery, this one is an MU09 battery which when I bought it, said that it was good for a G62. Now when I try to use this battery it only works if A: the laptop is plugged in, or B if I have it set to high performance mode.
My OS is Windows 7 Ulitmate. I am at a loss, but assume it involves either me having bought the wrong battery, or some issue with the system, any tips on getting it running in balanced mode?
