Issue

While connected to an auto power inverter the mouse pointer may become to difficult to control.  Possible symptoms include the mouse pointer floating across the screen and/or jumping around the screen randomly.

These symptoms occur only when the internal TouchPad or accupoint is used, not with an external USB mouse.  

 

 

Resolution

Use an AC adapter with a three-prong plug in place of the AC adapter included with the notebook and ground the inverter to the chassis of the automobile.   Alternately you can ground the notebook to the chassis of the automobile.
