Wake up from sleep with Microsoft AC Adapter

Hi Andy,

Thank you for posting in Microsoft Community, we appreciate your interest in Windows 10.

I understand your concern to restart the laptop from sleep mode when connected to AC power adapter.

Please be informed us if you are facing any problem with while waking the computer from sleep mode.

I suggest you to update the drivers for AC power adapter from
Device Manager and check if it helps.

Steps :

• Press Windows key + X key when you are at desktop.
• Select Device Manager.
• Expand AC Power Adapter.
• Right on the W and click on Update driver software.

If the drivers are updated, you will not have the option to Update Driver Software.

Step 2: If that does not fix the issue, please reinstall the display adapter drivers.

• 
  Right click on the Start button from the desktop and select
  Device Manager.
  
• 
  Locate and expand Display adapter.
  
• 
  Right-click on the Display adapter
  that is listed and click “Uninstall”.
  

Restart the computer and download, install the latest drivers from the NVIDIA website.

Windows defender is turned off and won`t turn back on

Windows defender on windows 10 enterprise won`t turn on. This happened shortly after i updated it; when I try to turn it on it says:

This app has been turned off and it isn't monitoring your computer.

And right underneath it, it says:

If you are using another app for malicious and unwanted software use Security and Maintenance to check that app`s status.

Need for a response ASAP, thanks
