A friend sent me this link – I think it’s neat. There are a couple of other videos there as well.
The “not a good sign” has gotten worse. My main computer totally refused to start at all today, so I was on the phone for a while. The best news is that under the warranty/service contract, someone is coming out to fix it tomorrow; we thought we’d probably have to take the computer up to St. Louis for service. Stay tuned!
ETA: The computer repair guy showed up on Tuesday as promised, replaced the power supply and my computer is back – hooray for Dell!
