Surface Pro 4 Camera Rear & IR Camera Front Device Power Failure

Question

Got a strange one.

I don't regularly use the cameras - front or rear - or Windows Hello for authentication. However, recently I noticed Skype wasn't finding any available cameras. (My S4P is a daily driver with no damage and as per PCI:DSS requirements, always updated.)

So. Checking Device manager - both the rear and front cameras are showing issues. 

Checking further - both show the same general error:

and

Initially, I thought to roll back drivers. No dice. The options for each device are grayed-out.

Then, I thought, let's reinstall the drivers. Three methods were used.

Firstly, I uninstalled the device via Device Manager - using the "delete the driver software" option. Rebooting seems to have no significant change. (Verified by checking the System / System32 / SysWOW64 folders after the process: uninstall + software deletion, I do not see the drivers in question actually being deleted.)

Secondly, I tried resetting the device to factory (removing documents after making a backup of my user profile). No dice. The same drivers are reinstalled (presumably with new/known-good drivers) and the device shows the same status_power_failure state.

Lastly, I've tried installing the Surface Pro 4 drivers & firmware, found here: https://www.microsoft.com/en-us/download/details.aspx?id=49498 - NO apparent change.

At this point I think I've pretty much exhausted my troubleshooting capabilities/options. However, I feel like this is probably related to a recent patch/update roll-up. Any help from the community would be greatly appreciated. 

'Cheers,

Answer 1

Just in case this matters - of course - my device just went out of warranty. LIke.. a month ago. :(

Answer 2

Also - EUFI settings are solid. All devices are enabled.

Answer 3

Did you get any resolution to this? I'm facing the same issue. All updates, uninstall/reinstall of drivers, disabled/enabled in UEFI, rolled back drivers, and still same issue. Will be taking the SP4 into the store this weekend since mine is still under warranty.

Answer 4

Nope - definitely take it to the store. No fixes/updates/workarounds have gotten me running so far. 

Thankfully - I don't really need webcam regularly. Still - irritating as hell for when I'm on the road.

Answer 5

Yeah I'm definitely not needing it but  I'd rather get it resolved now while I've got it under warranty. Will let you know if I find anything out from MS
