My function key cannot control the brightness of my laptop


Are you pressing the 'Fn' key (usually blue lettering) to the left of the space bar before trying the function key for brightness?

Laptop function keys are either set to function as regular function keys or as system specific function keys, like volume and brightness control, when the system starts up. When you hold the Fn key, it makes that key do 'the other' function. These settings can be changed in the BIOS, of EFI settings. Though changing them is easy, you may want a semi-tech-savy friend to help the first time.

All the best to you,
KerryHos

My function keys of hp probook 4420s is not working


You have to Press and Hold the FN function key at the lower left portion of your keyboard then hit the volume or brightness keys. Notice that the volume and brightness keys are the same color as the FN function key. That means you have to press and hold the FN key while you hit the volume or brightness key.

Cant turn up volume my compaq presario laptop


Ok it could be a few things, I am assuming that you are using XP and its a laptop, so lets try these:
  1. Can you turn up the volume by using Control Panel -- Sounds and Audio Devices --- Device Volume slider?
  2. On some Compaqs, the controls for audio are activated by holding down the FUNCTION key (usually blue letters on key on the left side of keyboard) and then pressing the audio up or audio down key. These keys are usally towards the top of the keyboard. These keys can do multiple things depending if the blue function key is press down first. They can control things like switching between internal and external displays, turning up/down the brightness on your laptop display and controling your audio levels too.
  3. Do you hear any sounds at all, if not, does Device Manager list your sound device?
  4. If this is a desktop PC, number 2 does not apply.
ok try those and let me know, Thx! =)
