How to enable Fn Key on HP, Dell, and Lenovo laptops

You can enable function keys (Fn key) on any laptop by changing the keyboard settings, using a key combination, or adjusting BIOS/UEFI options. On most laptops, the function keys serve the dual purpose of being standard keys for software shortcuts or special functions, such as adjusting screen brightness or volume control. Since they are set to special functions by default, you need to press Fn + F-key for standard functions and enabling function keys eliminates the need to hold the Fn key for actions like refreshing webpages or opening developer tools.

Use the Fn Lock Shortcut

– Save and exit

Use the manufacturer’s software
Some laptops might require using the manufacturer’s software to enable function keys. Depending on your manufacturer, look for software such as HP System Event Utility, Lenovo Vantage, or Dell Feature Enhancement Pack. Open the software and look for Function Key or Hotkey settings.
