VAIO SZ Screen suddenly turns black

Hello,

i have a problem with my 2 year old vaio sz. Since some weeks, screen turns black in irrregular intervals. The system is still available, but i can't see anything on the screen. The only solution is to push the power button an switch to standby mode. Afer pushing the power button again, the system comes up again and the screen turns on!!! The problem only occured in battery mode.

I tried nearly everything to fix the problem. I reinstalled Windows XP, tried different power management settings... nothing worked.

Please help!

 

no ideas?....

 

Maybe you could be more specific - there were 21 different SZ models over the years...
(7 series, 3 variations each in Europe)

So, post detailed model information, hardwarem, possibly display drivers, check windows error logs.
It seems that you use XP, is that correct?

Details.

 

Model number?

It's two years old. A lot can happen in two years. What kind of preventative maintenance have you taken? (for example: do you clean the vents on a regular basis? replaced the fan unit?)

Are you using the original battery that came with the notebook? Are you primarily running (XP) under Speed mode? Does this same problem occur when running under Stamina mode?

With the information you did provide it might possibly be related to the battery. It might be helpful to know how much of a charge the battery retains after a full charge cycle.

Since the symptoms seem to be video related you should also provide the video driver versions. (both integrated and dedicated)

 

^ how do you suggest to clean the vents? the best way in general?

 

Sounds like this problem:
