Broken Computer

My computer is broken! Turns out the old Inspiron 1100 laptop won't work without it's battery, and the battery has gone kaput! It hasn't really worked as a battery for a long time, but I use it plugged in so that never bothers me. But recently it started shutting down with a 'critical battery' error even when plugged in. So a new battery is in the mail, but until it arrives I have to sneak on and use Dave's computer when he's not using it :(
