I have a VGN-AR21S on Vista Premium and the battery (although it is in position) it is not detected.I can only run my notebook pluged in,and get power directly through the adapter...If I disconnect it I can't start my computer...What should I do???
A simple way to check if this is a battery or possible hardware problem is to take your Vaio to a local stockist and ask if you can try another AR's battery in your Vaio..
