OPTION ONE

Using Device Manager

1. Open the Control Panel (icons view), and click on the Device Manager icon.

2. To Prevent a Device from Waking up the Computer

A) Check and see a list of your installed devices that are able to wake up the computer to help know what devices to set in Device Manager. (see screenshot below)

B) In Device Manager, expand the category (ex: Keyboards) that the device is under, then double click on the device (ex: Logitech HID-Compliant Keyboard). (see screenshot below)

C) Click on the Power Management tab, uncheck the Allow this device to wake the computer box, and click on OK. (see screenshot below)

D) Close the command prompt.

3. To Allow a Device to Wake up the Computer

A) In Device Manager, expand the category (ex: Keyboards) that the device is under, then double click on the device (ex: Logitech HID-Compliant Keyboard). (see screenshot below step 2B)

C) Click on the Power Management tab, check the Allow this device to wake the computer box, and click on OK. (see screenshot below step 2C)

4. When finished, close Device Manager.

OPTION TWO

Using an Elevated Command Prompt

1. Open an elevated command prompt.

2. To Prevent a Device from Waking up the Computer

A) Check to see a list of your installed devices that are able to wake up the computer to help know the device name (ex: Logitech HID-Compliant Keyboard) to use in the command below. (see screenshot below)

B) In the elevated command prompt, type in the command below and press enter.
WARNING: Be sure to write this device name down in case you want to be able to enable it again in step 3. Once you disable it, it will not be listed again in step 2A until enabled again.

powercfg -devicedisablewake "exact name of device listed in step 2A"

For example, for the Logitech HID-Compliant Keyboard device listed in step 2A, I would type this command below exactly and press enter.

Code:

 
powercfg -devicedisablewake "Logitech HID-Compliant Keyboard"

3. To Allow a Device to Wake up the Computer

A) If you did not write down the device name (ex: Logitech HID-Compliant Keyboard) from step 2 that you disabled, then you can also look in Device Manager to see the name of the device. (see screenshot below)

B) In the elevated command prompt, type in the command below and press enter.

powercfg -deviceenablewake "exact name of device listed in step 2A or Device Manger"

For example, for the Logitech HID-Compliant Keyboard device, I would type this command below exactly and press enter.

Code:

 
powercfg -deviceenablewake "Logitech HID-Compliant Keyboard"

C) If opened from step 3A, you can close Device Manager now.

4. When finished, close the elevated command prompt.
