Sorry for the multiple threads. Each time I pressed space bar a new thread was posted. But back to my question. The backlight on my keyboard (the second most recent powerbook) stopped working. After searching the forums, i found someone recommended repairing permissions and zapping pram. I repaired permissions using onyx and rebooted. The backlight worked. But about 5 minutes later the backlight quit again. Now not only does is not work but when i push f8, f9, and f10 the backlight signal doesn't appear. When i look in system preferences under the keyboard the adjustments for backlight don't even appear. Any ideas what to do? I'll try repairing permissions again, but i'm assuming that will only work short term. How do you zap pram and will it help me at all? Thanks and i apoligize for spamming the forum.
