Q: Missing LCD screen, can't update OS

Hello all,

I'm having an issue here that I can't seem to conquer. Running an old PowerBook G4 Titanium with a missing LCD screen (snapped off long ago). I've been able to use it while hooked up to an external monitor via DVI and mirroring; However, I haven't been able to upgrade the OS because when the CPU restarts and boots from the CD, the installation instructions default to the original (missing) screen and I therefore can't see anything. I have read before about running in "clamshell" mode and having an external keyboard and mouse attached, but this has not worked for me as there is no screen to close. I've tried mirroring (F4), and even dragging the installation screen contents over, but to no avail. Does anyone out there know any way around this?

Thanks in advance.

----------

PowerBook G4 Titanium, Mac OS X (10.4.11), 1GB SDRAM

    It sounds like you are doing an OS upgrade from DVD, not software Update over the net? So you are trying to go up to OS10.5?

    I'm not sure if this will work, but you should be able to simulate a closed screen by placing a magnet on the trackpad, or very near it. IIRC, there's a magnet in the lid that comes near the trackpad when the lid is closed. Get a magnet and move it around the trackpad area until the PB sleeps. Then you should be able to do clamshell mode.

    IIRC, you may be able to put the Tibook into Target Disk Mode, then use another Mac with Firewire to install the update onto the Tibook.
