          D/T3546                                                               
                                                                                
                                                                                
                                                                                
 SYMPTOM:                                                                       
 Erratic movement or drift of the arrow when using a Microsoft                  
 mouse of +5 volts with a 3546 Dock II and Thinkpad.                            
                                                                                
 PROBLEM ISOLATION AIDS:                                                        
 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.                                                                       
                                                                                
 FIX:                                                                           
 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.
