I've been having trouble with my Dell laptop. The computer hasn't been recognizing the AC adapter, so while the computer works, it has only been running off the battery and not recharging. I dealt with it in the same way I deal with most electronic problems--I took it apart and put it back together. You'd be surprised how often that works, and indeed, the AC adapter is now recognized. I'm hoping it continues to work, but I sent an e-mail to Dell support anyway. Chances are that the computer's jack has a flaky mechanical connection. According to the Dell bulletin boards, this problem is pretty common.
In other news, I've set up a wireless router in my home. I've named it Eyrie, which is appropriate since my laptop is named Gryphon. (My main computer is Dragon, and the network is called Lair.) So far, everything is working, and the computers can talk to the Internet. I had a harder time getting them to talk to each other, but that eventually started working.
