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.
Turn off the computer display, leaving the screen blank. To turn the computer display on again, press any key or press the TrackPoint pointing stick.
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.
