If you are unsure about the features of your laptop, you can check the manual to see if it has a backlit keyboard. Alternatively, you can look for the backlight symbol on the keyboard functions. You can even look up your laptop model online to see its specifications and features, which is easier to access than using a manual.
Good luck!
