I bought a used IBM Thinkpad off ebay for $150.00 including a docking station to run some very old, very expensive software I don't want or need to upgrade. Shit uses a Sentinel Security Key that requires an LPT port. Yeah, try finding a laptop with one of those. Anyway, this thing rocks and rolls on XP Professional and one day starts typing random gibberish when I use the laptop keyboard. It takes a while but I finally deduce that some of the the letter keys have figures and numerals on them, and somehow I hit a key combination that turned on the laptop keyboard number lock. I was about ready to pitch the thing but finally figured it out. I hate working on a laptop but this one has changed my life with freedom from the office.
