Yes, this is a problem that occurs now and then, and Dell knows
about it as it appears on their consumer boards. My laptop uses
the Intel 945 driver, version 6.xx or 7.xx. You describe my
situation almost perfectly, and I know the screen illumination
is ON (can see slight bleed of light), but the LCD pixels are
all OFF. In other words, the problem is NOT the illumination
panel behind the LCD but the LCD itself.
Dell has had me reinstall versions of the video driver, to no
avail. Because the problem is intermittent, it might work three
or four times and appear to be "cured", then fail the next time.
Dell's next suggestion was to replace my mother board, but since
the situation changes with driver changes, I suspect software is
the problem.
I dislike this, but have been tolerating it knowing that new
video driver editions are forthcoming. And, somewhere/someone
has solved it - hopefully that information will be shared!
PLEASE post advice here, or send it to me at the address above
(remove the obvious).
Thanks!
