To enable your keyboard backlight, please follow these steps:

Locate the backlight function keys:

Look for keys labeled "F9" or a key with a small icon of a keyboard with a backlight.

You may need to press the "Fn" key (usually located in the bottom left corner of your keyboard) along with the backlight function key to activate the backlight.

Try these key combinations:

• F9/Fn+F9: This combination typically cycles through the backlight modes (off, low, high). Press these keys repeatedly until the backlight reaches your desired brightness.
• Fn+Fn lock (ESC): This combination is often used to toggle between function key mode and standard key mode. If your backlight isn't working, try pressing this combination to ensure that the function keys are enabled.
