How to Adjust the Brightness on an HP Pavilion Laptop
1 Examine the row of keys located at the top of your keyboard, also known as the “function” keys. Find the two keys that feature an icon of a sun next to an up or down arrow. These are often the F7 and F8 keys. You will use these keys to incrementally raise or lower the brightness level of your display.
2 Find the “fn” key, commonly in the bottom-left corner of your keyboard to the right of the “Ctrl” key.
3 Hold down the “fn” key while pressing one of the two keys you found in the top row. Adjust the brightness level in this manner until you reach the desired setting.
1 Open the “Start” menu and select “Control Panel.”
2 Click on “System and Security” and select “Power Options.”
3 Locate the slider labeled “Screen Brightness.” Click on the slider and drag it to the desired setting.
