Is the NumLock key on? The NumLock key changes letters to numbers on the right side of the keyboard.
You reloaded Vista. Did you set up networking and wireless? Did you enter your wireless key?
A while ago I plugged in a keyboard to my laptop so that I could have the keyboard on my lap while I worked. On a recent trip that I had to take my laptop with me (did not take the keyboard) I discovered that when I went to type something, words...I would get numbers when i keyed in letters. Now it gets better, i googled and googled and could not find a solution, so I decided to re-load the operating system (Vista) and now, not only do I still get numbers when I try to key in words the darn computer cannot find my network! So now it seems that the numbers issue is no longer an issue since I can't connect to the Internet. Any help that you guys can give would be greatly appreciated!!
