I've got this laptop ( model : ASUS A3Fc , running Windows XP ) and it's got a serious problem and it seems I can't handle it on my own.The problems is it's battery.It can run using AC , but it won't show me the percentage of battery left.Now I'm starting to even have problems with the laptop using AC.
I had updated the bios version , I have installed an ASUS update fix for battery issues from the ASUS website and installed SP3.Nothing worked.PLEASE !! Any suggestions ?!?
