Q: Powerbook 1400 with bad case of GLOD

Has anyone ever solved the GLOD problem? (green light of death)

I just acquired a PB 1400 166. I got it working very well including wi-fi. Very proud of myself.

I attempted to startup from a jaz scsi drive with OS9. I admit, I don't think I terminated correctly as in double termination. It refused to boot giving 'system' or 'bus error" message. I really thought that termination was internal.

Shortly after this, the PB was unresponsive with the sleep light glowing steadily green. I have read numerous articles on the subject of GLOD and tried all sorts of resetting pmu strategies

The pram batterries are, I believe, weak -- even there is some current inside even when battery and ac adapter are out. Replacements were on order anyway. The main battery may be failing even though it puts out 9.6 v.

I am going to hurl this PB out the window if the termination thing ruined it.

HELP!

Mac Pro, G4, 9650, PB100, Mac OS X (10.4.10)

    Termination problems are unlikely to have caused it permanent damage.

    Try removing the main battery and leaving the computer connected to the charger overnight, in hopes of giving a good boost to the backup battery. Then use the reset procedure (sometimes takes several tries) and see it you can get it to go.

    Hi Tim, sent you a pm just now.

    I'd reset the power manager as I suspect that pram battery might be causing the issue. Hold in the reset button on the back between the mini din plugs for a few seconds.

    If you are tossing it out a window toss it towards 1 Yonge Street..... just kidding I think it will be fine. I'm guessing you are in Canada from your email, if you are local to me maybe I can help we can test things out by swapping bits from one of our parts donors.....

    You didn't add any memory did you?

    Niteshooter does it! Removed one memory card, reset the PMU and it boots up. While I'm happy about that, I can't help wondering what happened to my 24meg card...

    Many thanks Kev.

    Cool, glad you got her sorted out.

    Funny thing, I think I have a bad 24 mb chip over here as well. Probably only a couple of companies that made them, wonder if it's got a lifetime warranty.....

    I had two dead G3 Wallstreets one with GLOD. Powers up with green light on and fan running, only way to stop it was to do a keyboard restart. Turned out it was a bad CPU card......
