Hi. I have a Dell Vostro 1720 that boots to the password screen, but the keyboard does not work--so I cannot enter my password. I've tried F12 and F8 (Safe Model), and the keyboard works on those utility screens, but does not function once the boot process is finished. I'm running XP Professional SP3. Does anyone have any suggestions? Is there a magic button I can press to restart the keyboard? : )
