    Power Failure Caused Video Problems ....

    Yesterday our neighbor was messing around with the circuit breakers and cut the power to our dining room, which turned off my external HD.

    I can still boot from the external HD, but there is a serious video problem now. I'm still online with the external HD, but having visual difficulty with certain things (buttons, links, scroll tabs, and pictures are really bad quality, e-mail hard to see ...).

    I can still boot from the internal HD (iBook G4), and the video is just fine. So the problem doesn't seem to be with the iBook's video card.

    I reinstalled Tiger (10.4) on the external HD, but still have the same problem.

    I ran Disk Warrior and Disk Utility, but still have the same problem.

    Any ideas what might be the problem, and how to fix it?

    It sounds like the external HD may be booting up in safe mode with forced low resolution.

    Try running this command in Terminal: sudo nvram boot-args=""

    I tried using the Terminal command, but when the computer asked for my password, I couldn't figure out how to enter the password. I tried typing my password, but nothing happened ....

    That is what usually happens keeps it secret from anyone watching. Go back to Terminal, type in password and hit return key.
