If you mute the sound and then turn off your computer, the sound will remain muted when

 

you turn on your computer again. To turn on the sound, press the Speaker volume up or

 

Speaker volume down keys.

Speaker volume down

 

 

Fn+F2

Microphone mute

 

When you press the microphone mute key, all of the recording devices are set on mute or

 

unmute; this is the default setting.

 

 

Fn+F4

Put the computer in sleep (standby) mode. To return to normal operation, press the Fn key

 

only, without pressing a function key.

 

Notes:

 

 

1. To use the Fn+F4 key combination, you must have the ThinkPad PM device driver

 

 

installed on the computer.

 

 

2. If you want to use the combination to put the computer into hibernation mode or

 

 

do-nothing mode (in Windows XP, shut the computer down or show the panel for turning

 

 

off the computer), change the settings in the Power Manager.

 

 

Fn+F5

Enable or disable the built-in wireless networking features and the Bluetooth features. If you

 

press Fn+F5, a list of wireless features is displayed. You can quickly change the power state

 

of each feature in the list.

 

Notes: If you want to use Fn+F5 to enable the feature specified in IEEE standard 802.11, the

 

following device drivers must be installed on the computer beforehand:

 

• ThinkPad Power Management driver

 

OnScreen Display Utility

 

Wireless device drivers

 

 

Fn+F6

Change the camera settings and the setting of the microphone mute button. When you press

 

Fn+F6, the camera setting window is opened.

 

Note: For Windows XP models, the setting of the microphone mute button cannot be changed.

 

 

Fn+F7

Apply a presentation scheme directly, with no need to start Presentation Director.

 

To disable this function and use the Fn+F7 key combination for switching a display output

 

location, start Presentation Director, and change the settings.

 

Note: If the computer is a Windows 7 model, it does not support presentation schemes, but

 

the Fn+F7 combination is available for switching a display output location.
