I prefer to use Sleep and Hibernate features whenever possible. In fact, I use Hibernate feature most of time so that I can quickly resume my work. Although Hibernate feature is not enabled on many machines by default, one can enable it by following our how to enable/disable hibernate feature in Windows 7 guide.
When the computer is in Sleep state, you can always wake it by moving your mouse or pressing a keyboard button. But, if you have a cluttered work space, you might want to prevent mouse/keyboard from waking up your computer as even an accidental mouse movement wakes up the computer.
If you have been using Sleep feature for a long time you probably have come across this issue. Users who would like to prevent mouse and keyboard from waking Windows from Sleep state can disable the same by following the below mentioned steps. When waking from mouse and keyboard feature is turned off, you need to press the power button to wake up your PC.
Follow this workaround to prevent mouse/keyboard from waking up your computer from Sleep mode:
Step 1: Open Device Manger by typing either devmgmt.msc or device manager in Start menu search area and then hitting enter.
Step 2: In the list of hardware categories, find the keyboard or mouse that you want to prevent from waking your computer.
Step 3: Double-click on the entry see the Properties dialog box.
Step 4: Switch to Power Management tab and uncheck the option named Allow this device to wake the computer.

Please note that all keyboards and mouses don’t support this feature. Most of the keyboards and mouses designed by Microsoft support this handy feature. And if you own Microsoft keyboard or mice, don’t forget to download Microsoft Keyboard and Mouse Center for Windows 7 to tweak and configure your mouse or keyboard.
