Scott, from what I've read and heard (including from a very capable Apple repair lady here in Fort Lauderdale) the PRAM battery can be a GLOD-contributor or even catalyst, so replacing it may not be a bad plan, especially when it's dead (as yours seems). Have never opened my 2400, so I can't say anything about the degree of difficulty. Good luck! -tobias.

I know my PRAM battery is dead because whenever I remove the main battery while unplugged, the date resets to some oddball time. The only suspicious symptom I get is occasional GLOD when I let it go to sleep on its own while running on battery. I've always been able to get it to come back after a few battery removal/ac adapter/power button manipulations. Will replacing the PRAM battery help this issue, or make it worse by retaining bad power manager settings? (I see at the website that some folks solve GLOD by discharging the PRAM battery on purpose.) I have lots of experience with mucking about in 1xx series Powerbooks, but haven't had the guts to crack my little Comet yet... Experience? Advice? Scott *********************************
