Windows 10: MS Surface Pro 7 front camera not working

I have an MS Surface Pro 7 whose front camera doesn't work. Device Manager reports the device with a yellow exclamation mark and the status This device cannot start. Code 10 STATUS_DEVICE_POWER_FAILUREI already googled quite extensively for that error but no suggestion so far helped. I tried practically everything that I found short of of a doing a system reset or a bare metal re-installation which I won't do - that darn camera is not worth such effort for me. Checking my system I found that in event viewer there are entries for "Surface Camera Front" reading:Errorevice ACPI\INT33BE

MS Surface Keyboard Cover not recognized by MS Surface Pro 3

My Surface Pro 3 cover mysteriously stopped working (other USB keyboards work).

I’ve exhausted all of the steps from the Internet and am hoping for some advice here on what to try next.

• Clean the metal pins on both the keyboard and the Surface Pro 3 with alcohol swap and q-tip.
  
• Performed the standard two button shutdown procedure - https://support.microsoft.com/en-us/help/4036280/surface-force-a-shut-down-and-restart-your-surface
  
• Update "HID keyboard" device in Device Manager.
  
• Uninstall and reinstall "HID keyboard device" in Device Manager.
  
• Removed HID keyboard device in Device Driver and manually installed Surface Type Cover device (which later automatically turns to "HID keyboard device" when you hit "update drivers")
  
• Updated all Windows 10 patches to date.
  
• Tried a brand new keyboard (Microsoft FMM-00001 Type Cover for Surface Pro https://www.amazon.com/gp/product/B073W4MPJF/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 )
  
• Updated firmware for Surface Pro 3 (typed in “winver”, took that Windows version, then downloaded the specific patch required here - https://www.microsoft.com/en-us/download/details.aspx?id=38826)
  
• Reset Surface Pro 3 while keeping personal files
  
• Reset Surface Pro 3 and deleted all personal files
  
• Performed hardware tests on aka.ms/surfacerepair (nothing bad found; all looks ok)
  
• Drained the battery most of the way before connecting again - the two times it worked momentarily these last few days was when I connected my new type cover keyboard to the Surface Pro 3 after the battery had died down to below 50%; a simple reboot later, everything stopped working. This user seems to have the same problem with it working briefly when there is low battery - https://answers.microsoft.com/en-us...pe-cover/52f983c6-2e53-49fa-aac6-7c4cc5d25d9f )
  

A breakdown of the steps I've done to sometimes get it working

• Leave Surface Pro 3 on about 2 hours on battery only.
  
• Power on Surface Pro 3.
  
• Working Keyboard.
  
• Turn off Surface Pro 3 (or reboot)
  
• Keyboard not working anymore
  
• Another similar user here - https://answers.microsoft.com/en-us...er-issue/2d6ed60a-c892-4ed9-907f-846fd9496f5a
  

Can anyone recommend any other troubleshooting steps? One of these steps seemed to work ok for others having this same problem.

Surface Pro 4 camera not working after latest Microsft update

Performed most of the above steps with the same outcome. Upon restart I get "Could not turn on the camera. Please sign on with PIN."

Thank you
