brightness button
Authored by: drjones on Aug 15, '02 03:17:12PM

On my Pismo sometimes this would happen. I tried the power manager reset
and the complete-shutdown-wait-30-sec restart type PRAM zap (zaping NVRAM)
It was resistant to fixing. Then I read that Pismos that show this might respond to a tickle of the brightness button. It worked. But now I just keep Energy Saver at 'Never' And I 'never' have to do this. YMMV.
If you're worried about preserving the LCD screen, just use a fairly dark screensaver.

Just a quick note: using a dark screen saver does nothing to prolong the life of an LCD screen. Unlike a CRT the individual pixels of an LCD screen are actually just color filters in front of a backlight. So when a pixel is black it just blocks all the light from the backlight. The backlight is what usually goes bad in an LCD, so the less it is on the better.
