Have you tried by changing sleep settings:

First go to "Control Panel" then "Hardware & Sound" -> "Power Options"

and you'll find various options over there, change them according to you needs.

These problems are quite frequent with laptops running Vista. try to remove the battery, press and hold the power button for about 20 seconds, put the battery back and then switch it on again. Also try the following settings:

• Control Panel -> Device Manager -> Mice -> Right-click your specific mouse -> Properties -> Power Management tab -> uncheck "Allow this device to wake the computer"
  
• Control Panel -> Power Options -> If "High Performance" is selected, choose something else, like "Balanced" -> Change plan settings (for the chosen power plan) -> Change advanced power settings -> Scroll down to Multimedia settings -> Choose "Allow the computer to sleep".
