Nothing come on, i mean no power not on battery or AC plugged in, no LED lights. i mean zero power on the system even though i rightly plugged it. i tried removing the Ram and HDD but its all to no avail.THE LAPTOP WONT JUST POWER ON. This started last week i came to office forgetting my charge and was using it on battery. the pc went off as the battery ran out but never came on again.
