Hello,

My Dell Vostro 2520 (modell no 2520-4568) does not turn on. If i press the on button the battery led flashes one white and three times Amber. If I change the battery nothing happens, not even led flashing. I tried to drain the residual power (by holding the on button without any power source) but nothing. I also tried another power brick. No luck. 

 

Please help,

Regards Balàzs
