My laptop is having an issue with the display.  After a few minutes, the 
screen goes dark - the backlight shuts off.  After closing the lid and 
re-opening, the display does come back for a short time.  I read the 
bulletin on the Toshiba site regarding the "button" possibly needing 
cleaning, but there is no button on my laptop, just a magnetic switch.  I've 
also reloaded video drivers, but the problem still exists.

Any ideas?

Thanks,

G
