first of all, I'm very sorry if I'm not posting this in the right board.
secondly, I'm sorry for my poor english in the following thread.

Well...I'm recently facing a auto turnoff issue on my acer aspire 4935.
I has been happening for 3days.
It was not a shutdown, but a "bius“ sound and everthing became black (turned off).
It happened when I was playing a game and the cpu usage was probably staying at 100% for about an hour.
After the sudden turn off, the laptop didn't restart, and when I started it again, before it reached the login page the laptop turned off again.
I have to wait for a few minutes then only I can start it.

After using a program called "speedfan", I observed the GPU value and it raised to 100C ++ when I'm playing the game. The values in the "core 0" and "core 1" entries weren't
seem like changing, they always remain the same since the program is started untill I restart the laptop.
However, I believe that it is a overheat issue, even the surface of the wooden table, the position right under my laptop is damn hot.

And before this, started about 3 weeks ago, my laptop easily get to 100% cpu usage. I checked the task manager and it seems to be normal (nothing weird that busts up the usage), there are all recognized programs, but before 3 weeks ago they weren't taking that much of usage, I'm not sure what's happening. =(

I'm don't know whether my fan is working or not, I'm going to call the customer service tomorrow, but I would like to get more infos from you guys before I do so.

So, it is a overheat issue?
Thanks for your help and sorry for disturbing you guys=)

Yeah, it does sound like overheating to me. A laptop's GPU should not go over ~90C. You can't feel air flow from your fan?

And, don't be sorry for disturbing us...it's why we're here .
