Fn key function
Contrary to what is stated in the
User's Reference
, the Fn+F11 combination does not change the
processor speed. Instead, the key combination switches between power modes as follows:
Maximum Performance
Maximum Battery Life
Customized
Setting for the TrackPoint
The
User's Reference
in the “Disabling the TrackPoint” section describes how to set Auto-Disable
if you are using certain mouse types, but actually the TrackPoint is set to Auto-Disable as the
default. With this setting, the TrackPoint is disabled automatically if a mouse is connected to the
external-input-device connector if any of the following is true:
– The system is starting.
– The system is resuming from suspend mode.
– Your computer is attached to the ThinkPad Port Replicator with Advanced EtherJet Feature.
If no external mouse is connected, the TrackPoint remains enabled.
A mouse that is compatible with the IBM PS/2 Miniature Mouse can work simultaneously with the
TrackPoint if the TrackPoint is set to Enable. To enable the TrackPoint, do as follows:
1
Start the ThinkPad Configuration program.
2
Click the TrackPoint ( ) button.
3
Click Enable for the TrackPoint.
