Surface Pro 7 Tcon error code 10

Question

Just today, my Surface Pro 7 i5 wont charge when connected to the stock charger but does charge with a USB-C charger. The battery indicator wont change to show its on battery and then I noticed this in Device Manager under Surface TCon:

This device cannot start. (Code 10)

STATUS_DEVICE_POWER_FAILURE

I have disabled the device, then re-enabled. I have attempted to reinstall drivers. I have ran the Surface Diag tool, Nothing has changed. I have restarted it, have shut it down and restarted. Not sure what to do next.

Janette_Z,

I see you have been answering alot of other problems lately. Have you given up on helping? Are we already out of ideas? If so, say as much so I can stop monitoring this thread and try elsewhere

Answer 2

To add to the issues Im having with this, now it wants to switch between desktop and tablet mode on its own, at random. I did a reset on windows, hoping that would fix the issue but it didnt.

Answer 3

And now my USB-C port is getting finicky as well. Most days I can connect my Anker 7-in-1 hub and everything works fine, today it wont recognize the hub; no video to external monitor and its not recognizing anything plugged into the USB ports on the hub.

I tried it with or without power to the hub. If I connect the the HDMI cable to the hub with no power, the monitor flickers on but says no signal. I tried straight connecting from the USB-C to the monitor and no video either. It is getting power through USB-C, I recharged my Surface from about 75% to full earlier today and it detects that its on AC power when plugged into the hub with power.
