Hi... I have a toshiba sattlelite pro 4300.  Occasionally the screen appears to loose power (light), it just went dark.  If you look closely, you still can see the images (desktop) and the OS is still functioning.  The power management is not set to do this.  And it's not the sleep mode it's getting into.

Thanks for your help.

And when does it do this? When it's running off the battery, or on the power grid net? How do you get the screen back? Have you checked if the light switch (by lack of better description, but it's somewhere on the laptop, that I know) isn't rolled all the way back to dark?

Thanks J.

It happens on both, battery & power.  I will need to cold boot it to get the screen back.  The light switch is fine.  Again, it does not follow any pattern.  The only thing I can think of is the light tub got hot or something...

That's going to be difficult as a laptop either has a TFT screen (like yours) or a bog standard LCD screen. No light tubes or electron emitter guns anywhere in sight. The pixels on the screen just get electrically fired, hence showing what happens on screen.

You saying that it doesn't follow a set pattern makes me believe there's a cable either loose or making a small shortcircuit. I'd say, let it be looked at by a Toshiba dealer. You can find the closest near you through http://209.167.114.38/support/Services/CanadianServiceLocator.htm
