TP 360,701,750,755,760 - Erratic mouse on docked ThinkPad
Applicable to: World-Wide
SYMPTOM:
Erratic movement or drift of the arrow when using a Microsoft mouse of +5 volts with a 3546 Dock II and Thinkpad.
CONFIGURATION:
Any ThinkPad 360, 701, 750, 755, or 760 installed in a Dock II using an external Microsoft PS/2 mouse.
SOLUTION:
To determine if the Microsoft mouse is +5 Volts check the voltage specifications on the bottom of the mouse.
Note: A Microsoft mouse with a 12 volt requirement will work correctly. It does not have the erratic movement or drift symptom.
If the Microsoft mouse does require +5 volts, the method to prevent erratic movement or drift is to disable the internal trackpoint on the ThinkPad using ThinkPad Features. Select the keyboard option and select the disable trackpoint option.
Note: The trackpoint must be enabled again if arrow movement is required when the ThinkPad is off the Dock II and an external mouse is not being used.
