I have a Compaq C500, XP Pro sp3, fully updated. Two Users, a passworded account with my name and password plus Guest.
A month ago the kbd had a bit of a spill of apple juice. After recovering from that it worked ok for a few days. Then the U and I keys slowly developed problems and eventually quit after 3 weeks of daily use. Over the next week the rest of the keys quit. There were no survivors.
I added a no-name USB kbd that has a Windows symbol on it. So it should be compatible. This kbd works fine on all my other pc's, auto installs just fine in XP and 7. So I started using this USB kbd, and WIN was finding it on boot, allowing me to use it to log in to my User account. Then a few days on this kbd starts acting up. It would spontaneously uninstall and reinstall, but then start working again. Then it got worse, frequent re-installs, then I couldn't use it to log in. I had to click on Guest account and try typing in Notepad for a few taps on a key before it started typing. Then I could use the kbd to log in. After another week that trick quit working. Now it wont work at all.
I checked the hidusb.sys file and it is there. So now I can't type unless I use the on screen kbd in Guest account. No way to check BIOS or do anything requiring the Admin level. Today I tried other "known working" kbds without success.
Can anyone explain this slow death and how I recover? To do anything involving drivers, installs, MrFixit, hotfixes all require Admin level. I cant get On Screen kbd access to open on the log in screen, I have no Win+U buttons available. Any slick tricks to solve this??
