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!

Dark screen when switched on


Try to adjust the screen brightness using your keyboard. If the brightness is at maximum, then you need to replace your screen because its backlight is dying.

Whenever my Dell Precision M6300 is ever on maximum brightness, the backlight goes dark after 1-2 seconds. The screen is fully functional, but the backlight simply isn't working. I can get the backlight to...


guess there is an larger issue with your notebook.....
you need to get the backlite changed, if you have chanaged the lite then there is a compatibility issue with the screen and the invertor board that's behind the LCD screen.
or the system is not supplying the correct current to the backlite / invertor board

a HW tech guy may solve your issue

Itouchs brightness is really low but the brightness level high


You tried setting the Brightness to maximum, but the screen remained dark? Could be a problem with the LEDs that light up the screen. Also try turning it off and back on.

Call the tech support for your computer. The backplane lamps and or the backplane power supply are defective. You will have to have the computer serviced to get the screen lit again.
