If the ESC key is flashing, Fn Lock is turned on. When Fn Lock is activated, the Esc key flashes every second. With Fn Lock on, the F1 to F12 keys work as standard function keys instead of media shortcuts.

• F1 to F12 work as normal function keys.
• Media controls such as volume, brightness, and playback need you to hold the Fn key.

To turn off Fn Lock:

1. Press and hold Fn + Esc for 1 to 2 seconds, or until the Esc key stops flashing.
2. When the Esc key stops flashing, Fn Lock is off.

When Fn Lock is off, the media shortcut keys work without holding Fn, and F1 to F12 need you to hold the Fn key.
