So, much to my relief, the battery was the culprit, so a simple battery exchange fixed the problem (and I got a new battery with zero charges out of the deal, so I guess I can’t complain too much!)

Speaking of power, Parallels Desktop may very well be the best piece of software I’ve ever used. I’ve been running Windows XP in Parallels for a few weeks, and it’s great. The main thing I use it for is work e-mail; the Java interface to the City’s Lotus Notes server doesn’t run perfectly in Firefox; you can read mail, but not send. At least I’m using IE7, so hopefully the security is at least a little better.
