My friend brought his Acer Aspire 7741Z w/Win. 7 64bit to me and said it doesn't turn on! so I took the Laptop plugged in the AC adapter to charge it up. I notice two things: 1) the power button doesn't even light up when pressed to turn on the sysytem and if I remove the ac adapter from the laptop after it is charged the power led goes off meaning that maybe the power adapter is defective. Also the laptop will not turn on even with a full charge, now I'm not even sure that the laptop is even charging completely if I cannot get it to turn on at all. I even tried Acer's website for answers but the warranty is out so I searched through support and saw an article showing how to reset the battery,I tried that and nothing.Does anyone have any idea what could be the cause of the laptop not turning on???? (the power led was red before I charged it and it's now blue indicating that it's charging or charged.) But it just won't power-up?
