Device Manager is the utility in Windows where all the connected devices are listed. Also, here you can identify and troubleshoot problematic hardware, and even change the power settings. But, for some users, the Power Management tab is missing in Device Manager.
The USB Wake Fit feature in Windows helps wake the computer from sleep using USB devices, such as the mouse and the keyboard. If the feature is disabled, the Power Management tab may be missing in Device Manager in Windows 11, so try enabling it.
The only thing that fixes this, is if I downgrade my Windows to older version (1909 for example) and I disable the "Allow the computer to turn off this device to save power" option under Power Management for the Bluetooth properties.
This will get you to the same dialog with the Power Management tab as shown above. To prevent other USB devices from waking your computer, just right-click on them, choose Properties and go to the power tab. For example, you can also prevent the keyboard from waking your computer or the network card too.
In the Properties window, select the Power Management tab. Uncheck Allow the computer to turn off this device to save power. Click OK to apply the settings.
Looked through every single line in Windows Device Manager, and disable/untick everything that power management tab > "allow the computer to turn off this device to save power". " - Not sure of negative effects.
OK this is how I fixed my problem in Windows 10 Boot Camp on MacBook Pro 2016. Apple Magic Mouse recognized, paired but kept disconnecting almost immediately if it connected at all. The problem was related to the Power Management under Bluetooth Radio, Properties in Device Manager. I had to uncheck 'Allow the computer to turn off this device to save power'. This has worked for me I'm relieved to say :)
If that fails to resolve the issue, expand the Human Interface Devices category (further down the Device Manager) and open the Properties pane for Bluetooth Low Energy GATT compliant HID. Then, switch to the Power Management tab and clear the box next to Allow the computer to turn off the device to save power.
Sorry for the three pronged reply but you also need to turn off Fast Startup in Windows 10. And I also disable Allow the system to turn the device off to save power check box, on the NIC. This is not necessary as your hardware does not rely on your OS.
Wake-on-lan is notoriously problematic since many options have to be just right. I have worked with it many times and still find networks cards which refuses to wake from S5 no matter what I do. However, usually the problem is not the card, but the driver. This can be proved by plugging in the card while the computer is in S5. The standby voltage powers the card and the LEDs illuminate when a network cable is attached. Wake-on-lan works from S5 in this situation with most network cards. However, if the PC is shutdown from windows, the driver may put the card in a low power state and wake-on-lan stops functioning.
Try disabling the allow the operating system to save power to this device, might also want to try disabling the other two check boxes as well. This is not necessary, as the WOL happens via your Hardware and not Software layer such as the OS. So technically the only is needed to enable WOL is turning of fast start up. Also update your BIOS if you can. 2b1af7f3a8
