I have a Acer One ZG5 AOA-150-1483 Windows XP I will try to describe the problem as best as I can! When I press the power button, the second light from left to right lights up for 2 seconds and the power button lights up for 4 seconds and then nothing...the fan wont turn on and the computer wont boot...I have read that people had problems with the BIOS but I cant do an upgrade because the computer dont do anything. I first thought that it was the charger because with the charger of another aspire one it turned on, I bought a new charger and it wont turn on...with or without the power supply does the same thing... CAN ANYONE HELP ME!!!!
