Trying to unweave, unwind, unravel
And piece together the past and the future,
T. S. Eliot
I have gone to the control panel, mouse, mouse properties, then hardware, then properties within hardware looking for the power management tab for the mouse. (Need to fix it so that the mouse will not take the PC out of standby.) (No power management tab for the keyboard either.) The other win xp pcs in the house have the power management tab. All are Emachines. T1140, T2692 and two T2893s. It is the new (last fall) T2893s that are the problem. Any help - direction will be appreciated.
