Thanks!
I tried the on-screen keyboard. Of course, I couldn't type on-screen as it came out ow-screew, but keyboard was enough.
Unfortunately, the n on the on-screen keyboard types the proper letter.
I have a USB keyboard somewhere, the problem is finding which "safe place until I need it" I stored it in.
I've downloaded the keyboard check, need to move it to the other computer.
A lot of good ideas. You guys are a great help.
I've used ThinkPad computers for about 20 years, and if this turns out to be a keyboard issue, it will be the first time. When I bought the USB keyboard, it was for a Dell desktop computer.
So I'll try the other suggestions, then decide if this 5 year old computer is worth saving (cost of parts and time involved).
Thanks again,
