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.

How do i adjust brightness in hp g60

Here's how to adjust the screen brightness for a laptop in Windows 7:
  1. Go to Control Panel -> Hardware and Sound -> Power Options.
  2. Click on "Change plan settings" for your laptop's selected power plan (either Balanced or Power saver).
  3. Now edit your plan settings by moving the sliders next to "Adjust plan brightness" at the bottom. You'll be able to change the brightness for when your laptop is On battery power, or when it's Plugged in.
  4. Once you've adjusting the brightness settings to your liking, then click on the 'Save changes' button.
Alternatively, here is another way: From the Windows desktop, hold the fn key and press the f7 key c00776226.jpg to increase or the f8key c00776225.jpg to decrease the brightness of the display. If using the function keys does not resolve the problem and you have a Lid Actuator on your particular model, check the movement of the Lid Actuator switch to determine that it moves freely and is not stuck. NOTE: The key numbers (f7 or f8 ) may vary depending on the notebook PC; however, the images on the keys should be similiar. If you reboot the PC after using the function keys to change the LCD brightness settings, the brightness may return to the default setting on some models, which is based on the power source-battery or AC. This is not an error. The notebook is functioning as designed. If the notebook returns to the default setting after rebooting on your particular model, use the function keys to change the brightness back to the desired settings.

How do I turn up the brightness on a HP Probook 6550b?

go to the search icon under start. search brightness. it will tell you step by step what to do.
Every laptop is different, so adjusting the brightness or contrast on your laptop may vary from the steps provided on this page. However, understanding the process of how to adjust the brightness or contrast will help you change your settings.
Most laptops adjust their brightness and other settings using the function key in conjunction with another key. For example, pressing and holding the function key (abbreviated as "Fn") and pressing the up or down arrow keys as shown in the picture below, increases and decreases the brightness.

How do I adjust the screen brightness on a HP Compaq 6510b laptop when the keyboard controls do not function? (running windows XP professional)

Hi, Actually, the problem here is you don?t have any options in windows XP to increase the brightness without using keyboard. HP does not provide any utility with the OS as it is OEM. Try this · Click on start > Click on control panel..... · Click on power options.... · Click on " Change settings plan "..... · Adjust the brightness and save the plan..... And exit... that should work.... OR Replace the keyboard and get the all things working

Its usually the Fn key (bottom left) and a function key on the top line like F1 to F12 the brightness is the picture of the sun. I couldnt find any specific information on your model but most HP's are the same.
