New description:

 Due to the same ESD sensitivity documented in Trac #473, it is possible
 that the touchpad assembly might lockup and not generate cursor movement.
 If this occurs, the temporary workaround is to power the unit off and on
 again to reset the er rors induced when static buildup discharges through
 the touchpad's controller ASIC.

 This is a very high priority fix for the B2 systems - details on the fix
 are noted in Trac #473.
