I have a T400 using Windows XP SP3. Recently my Volume Indicatore bar at the bottom of the screen disappeared. It's the one that pops up when you hit one of the three volume bottons on the top left of the keyboard. It gives you the volume level in a bar graph fashion.
For some reason, it just stopped coming up when those buttons were pressed. Well, in an effort to get it working again, I decided to load the latest audio drivers from the Lenovo website for the Audio. I have since loaded the audio driver 22.214.171.124/126.96.36.199 which required also loading a new Power Management driver and Hotkey driver. Once loaded, I know get the audio bar, but instead of it missing, it now won't go away. Right after I boot the system, the bar is not showing. If I press either one of the volume buttons at the top of the keyboard, the bar comes up but doesn't time out.
I don't know which is worst, not having it, or having it all the time where it gets in the way.
The only thing I did recently was purchase a docking station. However that didn't require and code to be loaded. So I'm at a loss as to what caused the indicater to stop in the first place.
Thanks for any help/suggestions you might have.

If I remember correct, it is not the audio driver, it is actually the hotkey driver and on screen display driver that is showing the 'special' keys such as volume buttons and the Fn + F1 to F9 buttons. See lenovo description at end of message.
You should uninstall these drivers, launch system update and reinstall using it, it should find the missing drivers.
However, your case may be due to a recent driver update which is not compatible with the on screen display driver, so if the reinstallation doesn't work, you would need to downgrade one of the drivers so they work in harmony.
