That’s right, my new keyboard! The guys at work got the DHL driver to look again through his route and they found it! And it appears to be working. It was a relatively painless operation, too–the directions were clear and I went in from the front, so I didn’t have to open up the back like I thought I would. No BIOS beeping upon startup either. Whoo-hoo!
I’m very very happy. Now I can actually do normal things again, like balance my checkbook. (Heaven forbid I’ve done anything to ruin my balance in the time I didn’t know how much money I had!)
