Hi GregoryDavis,
Thank you for posting in Microsoft Community. I understand that you are experiencing an issue with your Surface Book 3 tablet not charging when connected to the dock. Based on the information you have provided; it seems that you have already tried several troubleshooting steps.
Let’s work together in finding the best solution to this issue. To get started I will ask a few questions to further isolate the issue.
- May I know the version of the Surface dock you have?
- Did you make any charges on the device before this issue happen?
- Did you try another power supply to the dock and still have same issue?
However, I would suggest you try the following steps:
- Check the power supply: Make sure that the power supply is working correctly and providing enough power to charge both the tablet and the dock.
- Check the charging port: Inspect the charging port on the tablet and the dock for any damage or debris that may be preventing a proper connection.
- Unplug the Surface Dock from the power connector on the back of the dock. Reset the dock PSU by unplugging it from the power outlet and waiting for 5 seconds. Reconnect the power connector to the dock, then plug the dock PSU into an electrical outlet.
- Try power cycle the Surface Book by holding down the power button for 30 seconds, then release it and wait for 10 seconds before turning it back on.
- Make sure that your Surface Book 3 has the latest firmware updates installed. You can check for updates by going to Settings >Windows Update> check for updates.
If the problem continues, it’s possible that the Surface dock you have doesn’t have enough power to support the Surface device. You may need to replace the dock. Just to set you an expectation.
