Acer Aspire One Keyboard notworking

Hello,

Attempting to help my daughter. She has the Acer Aspire One Model D250-1151. As as it usually happens, the warranty just expired. It was given to her in exchange by a friend who owed money and he can't find the manual. Grr! So far no issues but yesterday she went to use it, logged on and has two usernames set up. One for her and one for her husband. Windows loaded in fine but when she clicked on her username nothing happened. So she shut down and rebooted, clicked on it again and the same thing happened. Not wanted to get mad, she tried to remember if she did anything different shutting down the night before and she didn't, and her husband hadn't used it for a few days. But mistakes could be made and she might have done something from the normal routine. So she called me for help but often it's harder to explain over the phone, so I said bring it over.

I played with it for hours and finally got it to click on her username but it would not let the password area drop down. Then it would just sit there. I would power down and reboot, and a few times it wouldn't even let me click on the username. It never let me click on her husbands username. Everytime Windows loaded fine or appears to load fine.

Running on Windows XP. The last running of her Antivirus and Malware came through clean.

I also attempted taking it off the adapter and running it on battery, to see it that might be a issue and I went into safe mode, last know good configuration.

I contacted Acer and there suggestion was to do a System Restore. Sadly she mad the mistake of uploading all her pictures onto this and hadn't had time to have them printed, so they would be lost and had deleted them from her camera.

And her or option other than a system restore. I did try several combination of Fn+F (and a #) but not having a manual) wasn't sure what the correct one might have been.

I'm wondering if something is locked...any help would be more than greatly appreciated.
