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?


PLEASE RATE ME!
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.

Disply screen has very little brightness


It could be a couple of things. The first is that screen brightness automatically dims when you go on battery, which is to save power. The second is that the brightness setting got changed inadvertently.

There are two function keys at the top of your keyboard that control screen brightness...one turns it up, the other down (they generally have a small circle with rays coming out...one circle is empty, the other filled...sort of like a sun and a dark sun). Hold down the Fn key and press one or the other of those function keys and see if that makes a difference in your screen brightness.

If that doesn't help, you may have a faulty LCD screen.

Hope that's helpful.

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

HP dv1000 monitor just stopped working.


Description During the startup or boot process of the notebook, the display is very dim and barely readable. It remains dim when it reaches the Windows desktop. Restart the notebook with AC power Perform the following steps to determine if the dim display is due to a hardware failure:
  1. Connect the AC adapter to the notebook and a working electrical outlet.
  2. Power down the notebook PC by pressing and holding the Power button for 5 seconds.
  3. Press the Power button again to start the computer.
If the display is still dim after restarting with the AC adapter connected try changing the LCD brightness. Change the LCD brightness From the Windows desktop, hold the Fn key and press the F7 and F8 keys to increase or decrease the brightness of the display. If using the function keys does not resolve the problem, determine whether the Lid Actuator switch is stuck. NOTE: The key number may vary depending on the notebook PC. The image on the key should resemble the following images: Figure 1: Brightness Level Down c00776225.jpg Figure 2: Brightness Level Up c00776226.jpg NOTE: During battery power operation, the notebook display will dim to reserve battery power. Adjust brightness control using the control panel Some notebook PCs have the ability to adjust the brightness through video drivers. If the notebook PC has video drivers with this capability, perform the following steps:
  1. Click Start , Control Panel and then double click Display .
  2. Select the Settings tab and click Advanced .
  3. If the feature is available, a tab with the video card name will be present. If it is, select that tab.
  4. Adjust the desired brightness.
Finding the Lid Actuator switch The Lid Actuator switch is a small button or switch located above the keyboard and LEDs on the right or left side of the notebook. It may also be located near the display hinges. Pressing this switch when the computer is on may turn the notebook display off or cause the notebook to enter a different power state. Press the switch 2-3 times while observing the display. If the display is no longer dim the switch may need to be repaired. Contact HP service and support for further assistance. Contact HP service and support If the display remains dim after the troubleshooting in this document it may be possible that the backlight is damaged. Please Contact HP service and support to schedule a repair
