This article discusses a by-design behavior where the Power Management tab is no longer available in the Wireless Network advanced properties in an Always-On/Always-Connected (AOAC) platform.
In Windows 7, you used to be able to see a Power tab inside the USB hub's device manager properties that showed the current draw for each device connected to the hub. That seems to have gone missing in Windows 10. Apparently, in the Device Manager, under the HID-compliant mouse or keyboard device properties, should be a 'Power Management' tab that allows you to check or uncheck an option: 'Allow this device to bring the computer out of standby'. Unfortunately, this tab doesnt show up for my mouse or keyboard (next to the General, Driver, and Details tabs). In update 1709 there was a power management tab when you right clicked a bluetooth device from the device manager and clicked properties. It was right next to the Events tab. Lenovo Power Management Driver. About Lenovo + About Lenovo. Our Company News. Jun 02, 2020 Where is Intel Bluetooth's Power management tab in Device Manager on Windows 10? There used to be a checkbox in Intel Bluetooth where I could turn on power saving for bluetooth accessories. But it is gone, no longer showing as a tab under any of the bluetooth items in Device Manager.

Summary
Consider the following scenario:
- You have a system that is an AOAC platform.
- The system is running Windows 8.
- You install the July update rollup 2855336.
- After the update is installed, you open up Device Manager.
- You open the Wireless Network adapter properties.
In this scenario, you notice that the Power Management tab is no longer available within the advanced driver properties.
More information
This behavior is by design. For Windows 8, update rollup 2855336 implements this change for Wireless adapter miniports on AOAC platforms.
With AOAC platforms, Windows needs to systematically manage the adapter's power state to achieve Connected Standby. Thus, the Power Management tab is not provided for the user to uncheck the Allow the computer to turn off this device to save power option. On non-AOAC platforms, the Power Management tab is retained.
This update rollup also addresses an issue on both platforms, in which the system might not be able to wake up after the system goes to sleep if the wireless adapter supports OID_RECEIVE_FILTER_SET_FILTER and the checkbox Allow the computer to turn off this device to save power is unchecked. This filter is used when an adapter supports NDIS packet coalescing, SR-IOV, or VMQ.
