TP General - External PS/2 mouse is not working
Applicable to: World-Wide
SYMPTOM:
Attaching an external PS/2 mouse to the ThinkPad and it either does not work at all or works erratically.
CONFIGURATION:
Any ThinkPad attaching an external PS/2 mouse.
SOLUTION:
First thing to check is to make sure that the end of the mouse that attaches to the ThinkPad is an actual PS/2 connector. If you are using an adapter to convert a serial mouse or an AT mouse connector to a PS/2 connector, it will not work. If you are using a standard PS/2 mouse connector, then it is possible that you may need to disable the Trackpoint on the ThinkPad to get the mouse to work properly.
ADDITIONAL INFORMATION:
To disable the Trackpoint for your ThinkPad, follow these instructions:
TP 770, 760, 765, 365X/XD, 380, 385, 600,560
1.) Open ThinkPad Features/Configuration.
2.) Click on the icon for the Trackpoint (
) and change it from Enable to Disable or Auto-Disable (the Auto-Disable is only available on some models).
3.) Exit Windows and restart your computer for the changes to take affect.
TP 355, 360, 750, 755

2.) At the main EZSetup Screen, select Config, and then Keyboard. Next you will want to click on Disable for the Trackpoint.
