I had a laptop with this problem. I pressed the power button and it sound ok but in a few secs the whole system stopped without even turning on the screen! Anyway,They told me my motherboard was burned. My laptop's mobo cost 400e,so i didn't acctually learnt if that was the cause.I suggest you show it to an expert.

With the info you give it can be too many things. 1.Your battery needs to be replaced. 2.Your on/off switch is broken. 3.Your charger is broken. 4.Try putting the charger in a diffrent plug. And many-many more. Give me more info and i can tell you for sure.

I had the same problem. My netbook kept freezing, so I had to hard reset it. This kept happening for about six months, until one day it started to heavily artifact on the “Starting Windows” screen (Windows 7). Same thing in safe mode. I replaced the RAM stick, hoping this was the issue, but it wasn’t long before it froze again. I borrowed an identical unit from a friend to compare. Swapped the hard drives, and my drive on the borrowed unit did not freeze (I ran this test for about 3 months). So the issue was definitely not the drive either. This lead me to believe that the issue was definitely hardware-related, so I swapped the motherboards. No freezing since. I assume there’s a defect with a batch of Aspire One motherboards, and my unit happened to be one of the unlucky few. Hope this helped!
