Start at the function row. The backlight key might be on F5, F4, or F11. If your function row is combined with other system buttons (e. g. backlight, volume, pause), you might need to turn off fn lock to access the backlight key. Press fn + the fn lock key to turn it off. The fn lock key usually looks like a lock with “fn” inside of it. Some laptops might place the backlight key in a column on the right side of the keyboard.
Enter BIOS. Select BIOS Setup or BIOS Setup Utility in the menu options. Press the arrow keys to go to the “System Configuration” tab. Move the selection to Action Keys Mode. Use the right or left arrow key to change Action Keys Mode to Enabled.
Enter BIOS. Press the arrow keys to go to the Advanced tab. Move the selection to Built-in Device Options and press Enter to open the menu. Move the selection to Backlit keyboard timeout. Press Space to open the timeout settings. Select Never to stop the backlight from turning off.
While you can technically remove the battery on sealed versions of the HP Pavilion, doing so requires you to remove the keyboard and several sensitive components before you can remove the battery, and thus is not recommended.

Click Shut down in the pop-up window.
Flip the computer over so that its bottom is facing up. Push and hold inward the switches on the battery compartment. Pull the battery cover away from the laptop. Pull the battery out of the laptop, making sure to store the battery on a soft, dry surface (e. g. , a towel).
Plug your computer back into its charger if your computer was low on power before you performed the hard reboot.
