I'm really back now. My laptop is gone. The computer store said it wasn't worth it to fix that model because it would just break down again in a couple months. One guy there told me that they had seen 15 or so of the Dell 5150 in the past couple months and that, since Dell obviously isn't going to do a recall, that someone ought to do a class action suit against Dell.
Oh well...so I'm on my old Compaq with a new copy of XP.
