Depression, sedation, and wot i learned from it

( Some things I've been meaning to write down so that I don't forget them )

Hm, that's about it. Turned out kind of long. :-)

techie question

I have an iBook G4 laptop. When I first got it 2 years ago, I could work at least 4 hours without it being plugged into the wall. Now, the battery-life is about 20 minutes.

What is causing this? And how can I get the battery-life to go back up to 4 hours??

Any suggestions from you techie wizzes out there gratefully received!
