Hello all! My little brother bought this laptop a while ago and had no problems with it. A week ago it stopped turning on. Taking out the battery and running it off the mains has no effect. When I press the power on button the following happens... Power button lights up blue All of the touch buttons light up blue (the ones by the screen) One blue light down by the touch pad turns on. The hard drive spins The fan turns on for all of a second then turns off The lights and hard drive stay on for 4-5 seconds then the laptop turns itsself of and tries to turn back on again. The screen does nothing at all, doesnt light up. PLEASE HELP!!!!! Thank you in advance!
