e420s on screen display

[sgmco]

Hey there -

I've got a e420s and all of a sudden my on screen display options aren't showing up. Typically when you change volume or screen brightness a bar appears that goes up and down depending upon the setting. The bar is no longer there, but on screen display is enabled.

Any ideas Think Pad masters?

Thanks
SGM

Try re-installing the Hotkey drivers.

Where do I locate to uninstall?

Programs and features in Control Panel.

no luck. i did find some new hot key drivers which i downloaded and installed, but didn't resolve the issue and in turn started giving me wireless issues. Which is strange.
