My VAIO laptop battery 1 is not available for use, the machine is now powered by battery 2 that after about 2 hours of usage. I need re charge it.
I've upgraded to windows 10 pro along with all the relevant software drivers download from sony. The machine is doing well except for this battery issue. Anyone had encountered this issue before? Any fix to it? Was it caused by the upgrade to windows 10? Or the battery that needs to be replaced?
