Shut Down Doesnʹt if Selective Suspend is Enabled

If after you attach a keyboard, a mouse or another USB‐based input device to your computer, your computer may no longer shut down correctly.

For example, your computer may stop responding (hang) after you click Turn off or Restart.

This may be because the selective suspend functionality is enabled on a device that does not support it.

This situation may occur when two or more USB‐based devices have the same vendor and product identification numbers, and when only one of the devices supports the selective suspend functionality.

To work around this issue, you need to disable power management of the USB hub.

Go to :‐

Right‐click My Computer, click Properties, click the Hardware tab, and then click Device Manager.

Double‐click Universal Serial Bus controllers to expand it, right‐click USB Root Hub, and then click Properties.

Click the Power Management tab.

Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.
