Hi:

Did you install the required graphics driver?

That would be the only suggestion I can offer.

ThankYou i just dint realize it. now i have installed graphic drivers and i can change brightness from the battery option but im still unable to change it directly using fn+f9/f10. is there any solution for this?

You're very welcome.

The only suggestion I can offer if you have not done so already, would be to install this software, restart the PC, and see if you can adjust the brightness using the Fn keys.

Now this is for the 2760p, you posted that you have a 2750p, but there is no such model.

This package provides HP HotKey Support for suported notebook models that are running a supported operating system. HP HotKey provides support for special function keys.

If you need the software for the 2740p, then you need this software...

This package contains the software that enables the HP Quick Launch Buttons, which are special function keys on HP Notebooks. This software works with supported notebook models that are running a supported operating system.

Anytime.

Glad to have been of assistance.

FYI...The 2570p uses this hotkey driver...in case you want to update it.
