I have a Thinkpad W500 (model 4061-B13) with Windows XP SP3.
I don't know why, but the OSD (On Screen Display) stopped working. The hotkey still functions well. I can use Fn key to change volumes, brightness. But there's no indicators on the screen.
I searched many forums but couldn't get a workable solution.
Here are the options I tried:
Option #1 Uninstall/Reinstall drivers in *specific* order (http://forum.thinkpads.com/viewtopic.php?f=48&t=74170).
Option #2 Modify the HKEY_LOCAL_MACHINE\SOFTWARE\IBM\TPHOTKEY\OnScreenDisplay registry
Option #3 Uninstall/Reinstall video and audio drivers.
Any pointer would be appreciated!

Scratch that. The solution was delete the whole registry key "HKEY_CURRENT_USER\Software\IBM\TPHOTKEY\OnScreenDisplay". The parameters in this key was somehow messed up. Instead of trying to fix the parameters, we can just delete the whole key. Log out the current user and log back in (so the changes can take effect).
Hope this helps!
