Purple Tentacle Registered. Hello everybody. I was wondering if anybody could help. When I turn it on, the Apple logo and spinning clock thing appear on the powerbook's screen just fine, but when it goes into the OSX login screen, the screen goes completely black. I have plugged an external PC monitor in, and what happens is that it appears to be using the external monitor as the primary display, completely ignoring the powerbook's screen.
Even weirder is that when I go into "display properties", the "application unexpectedly quits"! To be honest I have no idea if this is a hardware or software error I hope it's software! I have also done that "power reset" thing where you hold down ctrl-alt-shift-power, which has successfully reset the machine to !
Tonight I am going to transfer all my files, music etc.

Darkshadow wandering shadow. Hmm, you should be doing command-alt-P-R instead. The above command resets the PMU. It might solve your problem. You may have to reset your display prefs after deleting that file; just warning you. Zammy-Sam Desertchild. Hi Purple Tentacle, I also think it's a software problem you got there. I have two suggestions: 1.
Oops, didn't see Darkshadows post. PMU is the power-management-unit, which only affects the battery. Thanks guys, I'll try the command-alt-p-r as soon as I get back home. I already ran a disk check and apparently it was fine, which was a dissapointment for once. I'm really not worried about messing with the display settings, especially since I'm preparing to completely wipe the lot and start again!

No biggie if it does, as like I say I'm backing everything up on my PC, but it's good to know. Thanks for not telling me to buy a new Mac or just send it off to Apple! Viro Registered.

It wouldn't break the bank and would facilitate a few thousand extra legacy sales! I can understand the annoyance, being an iBook G4 user myself.
Hope you have PC access. I think SI admitted that it was an oversight and it really should've had the Intel logo, not a Universal one. I think I'll try it out now and see if I get a different outcome. Could it be my graphics card? Be interesting if you tried for a refund as google seems to suggest Software is not 'tangible goods' and EU law was proposed to make exception for it, but I didnt see any follow up on that..

The screen was partially replaced by the command line telling me that a kernel problem happened. Then I took off the battery and replaced it after a while. I turned it on and heard the chime but the screen was totally black. The caps, num lights works but nothing more.
