Hello
i have a vaio VGN-FS115MR which i've had for almost two years. I am overall very happy with it, but a couple of months ago the battery started to wear down and last about 15mins. So i decided to swap it with a friend to see whether it was the battery or another problem, and it isn't the battery.
what could it be? and if i send it to sony to be fixed how much is it gonna cost?
thanks
