Having problems with your PC Laptops ?

Lcd turns off when i connect power supply to my laptop

\015 Hi,when i run my laptop on battery power it works fine but when i connect to ac power the lcd gives a buzzing noise after a few moments and starts to go out. my laptop is Toshiba tecra8100. if you press and release the small button just under the lcd, that is supposed to turn it off when the lid is closed, the lcd turns on for a few moments but goes completely blank after a second or two. Can you please help me with my problem.Best regards,Abdullah\015

Answers :

First it sounds like where the ac adapter connects through at has possibly burnt out some locations on the motherboard, if I were you I would keep this part of the system turned off as much as possible until you get it looked at by a technician, a technician will need to to take that apart and specifically test these areas on the board find any and all shorts, replace where necessary on circuit parts.
