Acer Aspire 5520 does not start up, power light blinking green

\015 I have an Acer Aspire 5520, 2 years old. It suddenly shut down, and will not start up again. The power light (on/off button) flashes green, but nothing else is happening. I've tried disconnecting the battery/ac power adapter to completely power the machine down, but when I reconnect them the same issue persists. The power light will start flashing green before I can even press it. I do notice that when I reconnect the power supply, I hear a faint noise, which I believe is the fan, for about 2-3 seconds, and then that stops. I did notice the computer did seem to feel a bit hot for a couple of weeks before this problem happened, so I suspect there might be a problem with the fan. I know laptops may shut down if they overheat, but would a problem with the fan cause the machine not to start up at all, even after it has cooled down? Any other ideas as to what might be the issue if not the fan? Thanks.\015

Answers :

I think it might be the motherboard, if its not regulating the voltage properly then to much will go thru the motherboard and the fan won't be able to cool things down properly. Eventually then the motherboard will fail and then no video like your having now.

Try these steps anyway just to be sure:

only hook up the AC Adapter keep the battery disconnected. See if it turns on, if you still get a blinking green light then go ahead and turn the laptop off.

At this point, unseat and reseat the memory one stick at a time in each slot one at a time. Try turning on the laptop after each stick reinsertion.

If that doesn't do it then disconnect the hard drive and the dvd drive from the laptop.

Then try turning on the laptop, if you still can't get video then the motherboard is bad and would need to be replaced.

At this point at least you would know for sure.
