      How to use the function (Fn) keys on the keyboard - ThinkPad R50, R50e, R50p, R51

      The following table shows what each function key (Fn) key on your keyboard is for and how to use them.


      • The Fn key works independently of the operating system.

      Put the computer in standby mode. To return to normal operation, press the Fn key only, without pressing a function key.

      Note: This combination of keys functions as a sleep button. The setting can be changed so that pressing it puts the computer into hibernation mode or even shuts the computer down.


      Control the power source of the built-in Bluetooth wireless device. This combination of the keys functions as a toggle switch of the power state.


      • In Windows 2000 or Windows XP, this combination of keys enables or disables the built-in wireless networking features (the IEEE 802.11 standard) and the Bluetooth wireless features.
      • All R50e and select R50, R50p ThinkPad systems do not have the built-in Bluetooth feature.
