Okay folk some similar problems but are there any solutions?


I've a 5-month old 1.5GHZ 768M 12" Powerbook. I put it to sleep. Moved it from one room to another. Plugged it in. Opened it up. Nothing.

Screen is black. Machine is alive. I can adjust volume. I can adjust brightness (though itmakes no real difference I can see the different between high and low).

I force the reboot and NOTHING. Boots up fine. I can hear my AIM connecting, but no screen.


I unplug the monitor from my G5, plug it into the PB (with adapter of course). Reboot. Hit the F7 key to sync up monitors and the computer is healthy and happy, but the monitor remains dead.

The Monitors preference shows the other monitor exists -- I can toy with placement and then drag my mouse over to the other monitor etc... However that monitor just wont fire.

So I've seen folks mention similar issues -- seems to involve the mac waking up with or without something (power, keyboard, mouse...) it didn't have before. I have not, however, seen any solutions.

So are there any solutions or am I brining this back to the Apple store. This is exceptionally sad since it's my girlfriend's 12" I was using since the HD on my 12" died. I'm so in trouble.

Thanks.

PS Only thing that has changed is last night I changed the Energy Saver settings to never put the computer to sleep when it connected to power. Someone mentioned corrupted Energy Saver settings in a related problem so I thought I'd be upfront no matter how silly that seems to me.

Please clarify whether you get no image or if there is just no backlight. If the backlight is dead, you should still be able to see the desktop faintly on the display. Either way, try the usual: reset the PRAM and PMU. If those don't fix it, it's time to go to the Apple store. It could be a cable issue, a dead LCD, or a blown fuse.

sounds like something that happened with my dell, the cable was faulty and i had it replaced..

is your PB under warranty?

Recently the backlight on my powerbook's monitor went out. I could just barely make out the image on the screen under very bright light, but under normal lighting it looked completely black.

It was under AppleCare, and after reporting the problem to Apple it was a very quick repair.

Hope this helps.

What happens if you turn off the machine and boot it back ? Does the screen work again?

I have had recurring issues with my PB not waking up from sleep and waking up with no display. Fiddling with the battery, holding down the power button didn't really fix the problem, but eventually the PB would wake up.

I called Applecare and the tech had me run through a key combo which reset the Power Manager (i think?) I believe it was Ctrl - Cmd - Shift - Power. I had to set the date once it had booted up). That seemed to fix the issue for me (for a good 4-5 months), but lately it has been acting up again.

You might want to call them as there were some specifics to the resetting of the power manager that I don't recall (had to hold it down for a certain amount of counts).

I have a similar problem with my 2-year-old G4 12" Powerbook. I just had the hard disk replaced, but now the backlight intermittently cuts out. I can close the lid to sleep the machine, open it and the backlight works again.

Any possible software/driver issue here? Or is it a hardware issue?
