This may seem obvious, but when your keyboard starts acting possessed, there may be an easy fix.
[ Music ] ^M00:00:05 >> Tom: StrackCZ [assumed spelling] posted this question on the CNET Forums at Forums.CNET.com. "Yesterday I plugged in a an external keyboard to my laptop with Vista Basic, I turned off the computer and unplugged the external keyboard and afterward the keyboard didn't function properly, most of my keys are alright but some of the, for example, K, I think, became a zero on the screen instead." As our prophet noted on the Forums, without more information we can't be absolutely sure but we think your problem is probably Num Lock, that stands for Number Lock, a key that's often used on laptops to provide a number keypad without having to add extra keys. With Num Lock pressed some of the letter keys turn into numbers and usually this is noted in a smaller differently colored notation on the key itself. So, if your keyboard suddenly seems possessed check the Num Lock key. See, there are no stupid questions, so don't be afraid to ask about your problem in our Forums, Forum.CNET.com. That's it for this Quick Tip, I'm Top Merritt, CNET.com. ^E00:01:07
