I have an HP 6100 Laptop that changes the letter keys from lower case to upper case and vise versa, when I set the caps key it will reverse. The number keys will not change, they stay in the upper case mode. Also when I try to select an icon on the desktop the computer will select all icons. I have done a complete install of Windows 2000 (format hard drive) and upgraded the BIOS, however, no change. I also tried installing Windows XP Pro and still no change. Purchased Registry Repair, installed and checked registry, found and repaired some issues, however, still no change. I tested the keyboard by using an external and nothing changed. I feel this is a software issue, not hardware, beacuse all hardware tested OK. Talked to an IT person and he said the computer mother board was most likely bad, I don't see how it could be bad. Can anyone solve this problem?
