How do i increase the screen brightness HP elitebook 8530p


Sounds like your keybinding/hotkey combo is not doing its job. (or your bulb in the display is going out)

You can open up Control Panel and adjust brightness from there.

Step 1 Click "Start ' Control Panel ' Hardware and Sound ' Power Options" to open the Power Options window.
Step 2 Click and drag the bottom "Screen Brightness" slider to the right to increase screen brightness and to the left to decrease it. Making this adjustment changes the brightness level only for the current power source; if you change power sources, the screen brightness may change again.
Step 3 Click "Change Plan Settings" on whichever power plan is currently selected.
Step 4 Click and drag the "Adjust Plan Brightness" slider to the right to increase brightness for each of the power sources, such as "On Battery" or "Plugged In." If you want high-precision numeric control, you need to access the advanced settings.
Step 5 Click "Change Advanced Power Settings."
Step 6 Click "+" next to "Display" and then "Display Brightness" to expand these options.
Step 7 Click "On Battery" and enter a percentage in the field provided. Choosing "100" will set the screen to maximum brightness; any other brightness will be a percentage of the maximum brightness. To increase the brightness, make sure the number you enter is higher than the current value.
Step 8 Click "Plugged In" and set its brightness percentage.
Step 9 Click "Apply" and then "OK" to close the Advanced Settings window.
Step 10 Click "Save Changes" to save any changes you made on the Edit Plan Settings page. If you only make changes in the Advanced Settings page, the Save Changes button will be grayed out. If that's the case, just click "Cancel."


Hope this helps!

The screen is really dark


Locate the Fn (Function) key on your keyboard. It may be on the bottom left side with dark blue letters. Locate the two "brightness" keys near the top of the keyboard. These will be in the "F" keys, possibly if F6 and F7. They should have little sun pictures or something similar to indicate brightness. Hold down the Fn key while pressing F7, or whichever "F" key your laptop uses to increase brightness. Tap F7 repeatedly until you reach the desired brightness. Fn must be held down as you continue to tap. Hope this helps.

Try changing your display time out to something longer. Select menu-> settings-> display -> screen timeout -> pick something longer.
You can also set your brightness to not automatic. Within the same display menu, select brightness and uncheck the automatic brightness box. See if that works.

I have an acer aspire 5315 and the screen goes black I have tried to go into set up and I have taken out bateries etc but it's still not working . Any help is greatly appreciated thanks


Hello mariawint589,

The following instructions are from the Acer Aspire 5315 user's guide (page 35):

The computer's power management system automatically blanks the screen to save power. Press any key to turn the display back on, three hings might be the cause:

*The brightness level might be too low. Press <Fn>+<right-arrow key> (Increase) to adjust the brightness level.

*The display device might be set to an external monitor. Press the display toggle hotkey <Fn>+<F5> to toggle the display back to the computer

*If the sleep indicator is lit, the computer is in sleep mode. Press and release the power button to resume.

If this solution is helpful please click a thumbs-up rating.

Have a great day,

When HP laptop is pluged into power source screen goes dim


Right click on the battery icon in the taskbar, go to Power Options or something similiar. Change the plan settings for the power plan you're currently in. Check the brightness ratio for both battery and plugged in mode. This problem might come if you or someone had tinkered with the settings.
