View Full Version : Powerbook Backlit Keyboard Problems
Sep 2, 2004, 02:40 PM
Noticed this evening that my keyboard wasn't lit up as the light faded in the room. Went into system preferences and sure enough it is switched on, and set to stay on, but isn't on. has anyone had problems with this ? Is there an easy fix that I'm overlooking or is this something big that's gone wrong ?

I have the same model Powerbook. I've noticed the same problem lately.
I've tried repairing permissions and checking every setting I can think of. Nothing has worked.
When I press the F10 button, it doesn't let me adjust the brightness, either.
I'm thinking it's about time for a call to Apple.

I don't believe this, as I'm reading this thread on my three day old PowerBook, I look down at my keyboard only to see the backlight is out.
And guess what? The F10 key doesn't work for me either!
I also checked system prefs and backlighting is on for me too. Cant seem to find anything on the Apple tech Support site myself. Anyone else managed to find any relevant articles?

I seem to remember seeing this problem on macrumors a few weeks ago. I think that simply switching the powerbook off and then back on again seems to fix the problem.
Hope this helps.

Go to to the /library/preferences and remove the com.apple.bezelservices.com preference.
Restart and see if that corrects it.

Thanks. Removing com.apple.bezelservices.com from Preferences worked. Keyboard lit up. Now can I trash that file or is it vitally important ?
Also, problem just happened again and I went back to preferences and com.apple.bezelservices.com was back there, or at least a new version of it. Any advice there ?

This is what's wrong for me.
Thing is, I was in a dark room! Very dark! Nighttime!
Despite this, the screen stayed perfectly bright and the keys never lit.
EDIT: Also from Apple, here's how to turn off the backlighting ...
Presumably we can do the opposite to make sure our backlighting is set to "on."
