How can I prevent my wireless mouse from waking my Windows 7 computer?

Solution 1:

Low tech solution: Put the mouse upside down on your table when its not in use. This prevents the optics from detecting any movement.

Solution 2:

  1. Go into Device Manager (use Search to find it)
  2. Find your mouse under "Mice and other pointing devices"
  3. Right-click it and choose Properties
  4. Go to the Power Management tab
  5. Untick the "Allow this device to wake the computer" checkbox.
  6. Click OK.
