My mouse goes to sleep consistently at the one minute mark after sitting idle. It is revived with a simple click of the button. This has been this way for 3 months but is becoming a pain and I want to solve it. I have Windows vista, home premium on a PC using an older MS wireless keyboard and mouse. version 1.0A. I checked to update drivers and put in fresh batteries. All MS updates have been made and the computer is up to date. The mouse/keyboard transmitter is about 4 ft from the PC and in trying to solve this problem, it has been moved to several positions. The usb connection has been tried in 3 different slots on the back of the PC. I have checked all the settings for the mouse in the control panel but see no reference to make the mouse go into a sleep state (or out of it). Suggestions?
