I got it back a few days later with the original OS reloaded! Completely missed the point on that one! I have not bothered again as suspect will just get the same result from them again and again. I contacted HP who said I must send them one of the laptops to they could see what I meant. Plugging the power cable in does not restore the brightness level, the only way we can find to do this is to either restart the laptop or put it into sleep mode and then wake it up.Īll the laptops are running the same version of BIOS and I have tried different HotKey and ATI/AMD driver versions. My HP notebook doesnt have any function keys, so how do I push F10. Click on Start -> Control panel -> Display -> Adjust Brightness at bottom you will find a drag bar Screen Brightness you could change your setting.

Continuing to press the Fn+F3 key (increase) just makes the screen get a little brighter, and then dim will do this in a loop. Increasing or decreasing the brightness of the screen via the keyboard shortcut is. When we first rebuild the laptops and install the Intel, ATI/AMD and Quick Button/HotKey drivers from the original swsetup folder we can use the Fn+F2/F3 to control the brightness.Īfter joining to the domain and performing updates we find that the display brightness does either not respond or if it does, it is fairly random.Īs an example: A reloaded PC with the same version of ATI/AMD drivers and HP Quicklaunch/HotKey drivers and software loaded will dimm it's brightness when you try to INCREASE the brightness using the Fn+F3 key. The build is a very basic build with none of HP 'fluff' installed.just the drivers etc. We have number of HP ProBook 4525s laptops that we have reloaded with Win7 Pro Volume License edition.
