M1 Battery Not Charging via Thunderbolt
Hello, I have Philips 279P1 external monitor connected solely by a Thunderbolt 3 cable to my MacBook Pro (13-inch, M1, 2020). It is supposed to provide enough power for the MacBook to operate and charge its battery, which it has for the past few months.
Today, I am not able to get the MacBook's battery to charge with this setup anymore. The screen acts perfectly fine as a secondary monitor with both image and sound, but alas no charging.
I have tried the following to no avail:
- Closing any apps that consume too much power.
- Restarting the MacBook.
- Shutting down, waiting a few minutes, and rebooting the MacBook.
- Disabling the "Optimised battery charging" options in preferences.
- Restarting the monitor.
- Resetting the monitor to its initial settings.
I'm on macOS Monterey v12.0.1 (21A559)
Any ideas as to how I can resolve this?
Thanks in advance.
