Note Many laptop manufactures will not allow a Bluetooth device to wake the computer from sleep mode because of the power consumption requirements to keep the Bluetooth radio activated (Bluetooth paging can consume up to 15% of the computer’s power). Therefore there are a couple of workarounds that you can use:
-
If you can open the lid of your laptop, use the embedded keyboard or pointing device or an external non-Bluetooth device to wake the computer.
-
If you cannot open the lid (for example, because it is in a docking station) or if you have it plugged into external power (that is, you are not using the battery), you can change the Power settings in Windows to not go into Sleep mode when plugged in.

More Information
The ability to recover from sleep mode by pressing a key on the keyboard or by moving the mouse on a computer that supports ACPI is dependent on the computer's motherboard. This ability is disabled in older Intel motherboards, and the only way to wake the computer from sleep mode is to press the Power button.
With most newer motherboards, you can wake the computer by pressing the Power button, by pressing a key on the keyboard, or by moving the mouse.
ACPI support is necessary to take full advantage of the power management and Plug and Play features in Windows. If you are not sure whether your computer is ACPI-compliant, please see the printed documentation for your computer or motherboard, or contact the manufacturer of your computer or motherboard.
