This article will show you how to turn on the keyboard backlight on an HP Pavilion laptop. You can turn on the backlight by pressing the 'function' key on your computer's keyboard, such as 'F5'. If your Pavilion laptop has lights that won't turn on, you may need to reset the lights by doing a hard reboot.
Method 1 of 2: Turn on the lights
Step 1. Connect your computer to the charger
In some cases, your computer's keyboard backlight will not turn on if your computer does not have a certain battery life without being connected to the charger. You can solve this problem by connecting your computer to the charger.
Step #2. Find the "Backlight" key
The "Backlight" key is always one of the function keys (usually "F5") at the top of your keyboard. It has a symbol with three dots on it.
Step 3. Press the 'Backlight' key several times
If your computer's keyboard is set up to use the hardware functions when the function keys are pressed, this will cycle you through the dimmed and bright backlighting accordingly.
Continue to the next step if nothing happens when you press the Backlight key
Step #4. Try using the 'Backlight' key while holding Fn
You'll find the 'Fn' key at the bottom left of your keyboard. If you couldn't turn on the backlight in the previous step, then hold down the 'Fn' key while pressing the 'Backlight' key. This will cause your computer to use the key to change the brightness of the backlight.
You may need to press the "Backlight" key a few times while holding down "Fn" to cycle through all the brightness options
Step 5. Make sure your HP Pavilion has a backlit keyboard
Not all HP Pavilion laptops have backlit keyboards. If you haven't been able to find the option to turn on the backlight yet, check your computer manual or online documentation to determine whether or not your keyboard has a backlight.
Method 2 of 2: Reset malfunctioning lighting
Step 1. Make sure your HP Pavilion has a removable battery
You can perform a 'hard reboot' on your computer to fix possible hardware issues with the backlight, but this will require you to remove the laptop's battery.
While you can theoretically remove the battery on sealed versions of the HP Pavilion, this will require you to remove the keyboard and several sensitive components before you can remove the battery and is not recommended
Step 2. Remove any cables or USB items from your computer
This includes the charging cable, USB sticks, speakers, and so on.
Step 3. Turn off the computer
This is how you do this:
- Click on the 'Start' icon
- Click on 'On/Off'
- In the pop-up window, click on 'Disable'.
Step 4. Remove the battery from the computer
As long as your computer has a removable battery, you can do this by following these instructions:
- Turn your computer upside down so that the bottom is facing up.
- Press and hold the toggles on the battery compartment.
- Pull the battery cover away from the laptop.
- Pull the battery out of the laptop and make sure to place the battery on a soft, dry surface (e.g. a towel).
Step 5. Press and hold the 'Start' button for 20 seconds
As a result, all residual current that is still in the computer will disappear.
Step 6. Replace the battery and close the compartment
At this point you are ready to turn your computer back on.
Connect your computer to the charger again if your computer had low battery life when you performed the hard reboot
Step 7. Turn your computer back on
Press the 'Start' button on the computer to do this. Your computer will boot as usual.
Step 8. Try turning on the backlight
Now that you've done a hard reboot on your computer, you should be able to go through your keyboard's brightness settings.
