fz11m freezes randomly

[cptbill]

Hi guys,

I have a FZ11M.
Problem is that it freezes when i leave it idle. That might happen sometimes after 10 hours, sometimes after 20 hours and sometimes after 3-4 hours. It happens randomly.
FZ11M stays idle (no processing, cpu is almost 0%) and the screensaver gets activated. So most of the times i find the laptop frozen (displaying the last image of the screensaver)and i can only shutdown the laptop with the power button(pushing it until FZ11M turns off)

Any clues what might be wrong?

thanks thalamus.
Indeed, a few days a person that i could talk to and understand the problem, called me.
They arranged to pick up my laptop.
I received it back a week ago. Repaired. The cpu was replaced (?!!)
Guess what. No freezing problem! It can stay switched on for days without freezing.
On one hand i am happy because i have my vaio back and the people on service were capable of find out what was the problem (my guess was the vga), on the other hand i had to wait almost 1 month to convince them that there was a problem.
