Solved! Acer 4520 shut down in middle of session

[alluci]

In the middle of a session the screen turn black, but the computer seem to be on... we need to stop it with the middle button and restart it again.
Usualy it start back normaly again.
But one time, instead of that the screen only turn black, the computer shut down totally to restart by itself... but that was the only time he did that.
Can you help me with this problem.. what can it be?

My guess would be this sounds liek an overheating issue. I would start by reading the article here and checking out the software to see if this is your issue http/www.makeuseof.com/tag/3-laptop-computer-temperature-monitor-apps-save-hard-drive/
