I have 2 main batteries for my netbook pro. The backup battery was reported 100% charge, so decided to change the main battery even if the device was not connected to the power supply.
Well, after inserting the new battery it completely resetted as it was before installing programs etc.
I restored the last backup
(it worked
) then tried to change battery again: same result, everything resetted without programs.
Am I doing something wrong?
Or is a hardware problem? Which is the purpose of the backup battery if it does not work when you need it?
