IBM ThinkCentre S50
PS/2 Keyboard USB Mouse
Windows XP

After a year of perfect operation, this machine ceased to respond to
keyboard or mouse at the log-in screen.
Symptoms:

-Numlock light stuck on.
-no light response pushing Num, Caps, or Scroll keys.
-no error beeps from too many key presses if I keep banging on teh key board.
-Mouse pointer is present but no movement.
-*Windows is not locked up.* If I hit the soft power switch, the OS does
return the little pop-up box that says "Windows is now entering sleep mode"
-*It is not hardware* The keyboard works fine in BIOS, linux boot, and even
the Windows safe mode selection screen. But if *any* Safe mode is selected,
the input devices shut down at the log-in screen again.
-Have already run "last working configuration" from safe mode. No effect.

SO the only interaction I can currently have with Windows is what ever I can
access after booting from a CD (basic command prompt function, registry
editing and whatnot).

What say you? Am I doomed to spending the time to salvage user files and
the nuke and reinstall, or is there some hope of fixing this with my current,
limmited access?

Thanks for grinding on my puzzle a bit,
daivd
 
Hi,

If you have an XP CD, try boot from it to recovery console,
in the command prompt, type chkdsk /r, press enter key
let it run. After it finishing and repair the errors, reboot to normal start.

You may also try the fixboot command, but you must be very careful as a
wrong select of command may demage your hdd. If you want to check the command
switches for the fixboot command, type "fixboot /?"

Hope it helps.
