Surface Pro doesn't wake up from Standby

When I put my Surface Pro into sleep mode (not hibernate, as I disabled that using powercfg -h off  via command line), pressing the power button, Windows button, or pressing keys on the keyboard will NOT wake it up... the screen stays blank, although I can press the Windows key and feel it vibrate as to acknowledge that I've pressed it.

My only solution is to power off the device and then power on, which is not ideal for obvious reasons.

I have not made any changes to power profiles or the device, and I've spent quite a bit of time installing my software and copying files... I really don't want to reset it if I don't have to. I have already installed all available Windows updates.

Any advice?

This from that other thread I referenced appears to have resolved the issue:

  1. Open Device Manager from the Control Panel or however you normally open it
  2. Expand Network Adapters and double click Marvell Avastar 350N
  3. Choose the Power Management tab and make sure the checkbox is checked for Allow the computer to turn off this device to save power

Thanks all!

Have you altered the wireless network card in Device Manager to not allow the computer to put the device to sleep to save power via the Power Management tab on the card? I had inadvertently done this and it caused my Surface Pro to not wake properly.

To clarify for anyone else running into this:

  1. Open Device Manager from the Control Panel or however you normally open it
  2. Expand Network Adapters and double click Marvell Avastar 350N
  3. Choose the Power Management tab and make sure the checkbox is checked for Allow the computer to turn off this device to save power

    I have the same issue.  I found the device in the Device Manager, but I have no Power Management tab (didn't have it in Win 8.1 and don't have it now in Win 10--still have the same problem with both OS's).  Any idea why that would be or where I can find it? I ran the troubleshooter as suggested.  It found no problems.

    There must be a registry entry or a command line that will allow the power management setting...

    The Power Management tab was taken away with an update, or so I was told. I had the same issue in trying to fix this. I figured the problem of not waking from sleep came after I had done the April updates, so I did a complete reinstall in April (right after posting) and only recently, at the end of July, did I do the April updates (I figured that was enough time for them to fix it). It works perfectly now.

    Good luck!
