I have Acer Aspire 5520G laptop. I turned it down yesterday and today when I wanted to turn it on it wont boot up. When I press power button it lights up ( green) there is some blinking of HDD led and you can hear the noise of fan spinning. Unfortunately that's it, there is no POST screen or anything else. It's just sitting like that and after few moments HDD led turns of too so only power led remains turned on. Fan turns down too but it turns on after some time and then off again and on again.
I tried taking out battery and removing power cable, then holding power on button for 60 second and then connecting only power cable back but same thing happens. I even opened it up and cleaned all part and disconnected CMOS battery for 30 second. But, still nothing.
Any suggestions would be appreciated.
P.S. I found some people talking talking about re-flowing their laptop parts but symptoms are different from what I saw. They are mentioning flashing power led light. Nothing flashes at my laptop.
