Before Windows Vista SP2, in order to wake a computer by using a Bluetooth HID device, an end-user had to use a special Bluetooth dongle, and it only was included with the keyboard, mouse, or desktop set.  In Windows Vista SP2, more Bluetooth controllers can be used with a Bluetooth HID device to wake the computer.  However, the success in waking the computer depends on the hardware configuration.  If the Bluetooth radio has enough power to receive the HID’s connection request, and the Bluetooth controller supports wake from the computers sleep state, then the system will wake.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
