Surface Detach Icon says Detached when it's not

I recently bought the new Surfacebook, however there's an issue that keep occurring. In the taskbar, it keeps displaying my tablet is "Detached" while it is attached to the keyboard. And when I take the screen off, it does not auto rotate even when the rotation lock is off. Also the hello sign-in does not work, it keeps displaying "Turning on Camera" but it never turns on, then I have to just sign in with pin or password. 

However when I force reboots/ shut down (Hold Power button + Volume up button at the same time for 30 secs) all these problems go away. I don't think this should be happening. And I feel like I shouldn't need to force reboot every time to fix this. Is there a way to fix this?

After installing system updates on 02/17/16 for Windows 10, the Surface Detach icon in the taskbar is grayed out and when I mouse over it, it says "Surface Detach: Detached" when it's actually attached and connected to the keyboard. Keyboard works fine but when I try to detach, I have to hold the keyboard detach button for over 10 seconds before the light turns green and I hear the detach sound. 

Also, since this started happening, after detaching, the screen no longer rotates in Tablet Mode. Tried locking and unlocking Autorotation and nothing will rotate the screen anymore.

Not sure if these two problems are related. 

THANK YOU

Hello all

We have noticed that in certain instances the 1/27/2016 update did not install completely and is now is causing the 2/17/2016 update to fail for some customers. To check that the 2/17/2016 update is completely installed and fix it if needed, follow these steps:

Check for Installation Success

1.  Enter the words Device Manager into the search box on the taskbar, then select Device Manager from the list of results.

2.  Expand the Firmware section.

3.  If the items listed here do not have exclamation marks, the 2/17/2016 update is properly installed.

4.  If the items listed here do have exclamation marks, manually reinstall the 2/17/2016 update following the steps below.

Manually Install the 2/17 Update

1.  Download the MSI package for Surface Book or Surface Pro 4.

2.  In Device Manager, double-click the item under Firmware that has an exclamation mark, select the Driver tab, and then select Uninstall. Do this for all items under Firmware that have an exclamation mark.

3.  Open and run the MSI setup package that you downloaded.

4.  Restart your Surface (do not shutdown).

Best regards 

Well, the update took, but I still have a grayed out 'Detach' icon.  What do I do now?

I could not get any suggestion in this thread to work.  Nothing on MS web has any good suggestions either.  I'm not sure what their doing in Redmond, but solving this and other problems seem to be off their radar.  It is disgusting to support Microsoft for 2+ decades without any work on real solutions.

I finally used 'Advanced Recovery' in Update & Security.  It has been lees than one day, but seems several problems went away.  I'll give an update in 24 to 48 hours either way.

Well, that didn't work.  'Detach' icon is now grayed out even though the screen is attached.  Also Windows Hello is no longer working.
