i hit some KEY on my Sony Vaio and it's making a 'u' a 4 and a "k" a 2, for EXAMPLE. The far left LIGHT next to the Caps lock is lit. Help!
look for the key probably in the top right corner..."Num LK" that is what you hit..do it again it will solve your problem.On many laptops, you have to press and hold the "Fn" key then press the corresponding F key (F1-F12) that releases then numlock. This key is labeled "Number Lock", "NumLk", or with a picture of a keypad.

Since I don't know specifically what Vaio you're using, that's about all the help I can provide. If your laptop doesn't have a "Fn" key, CONSULT your user's manual. It will tell you how to turn on and off the number lock or keypad function.

And if you're really still stuck after all of that, try this: Some laptops will respond to an external keyboard's numlock key being pressed. Plug one in, press the numlock, unplug it.Hey quaxo. Where the heck have you been?haha here and there. Been really busy with WORK, my girlfriend's visa, this and that.How is your girlfriend's friend, means, my girlfriend doing?I think I always had to hold the Fn key and then press the NumLk key.
