Hi there!
14" Pro super-base model since half December here, with the base charger.
macOS Monterey 12.1 installed, and since about a week I'm having power issues only in a specific room in my office, so it may be an electrical system issue of the building.
There are three outlets here and a random one of these situations happens (dice roll):
- working perfectly
- completely non-working (Magsafe light off, no sign whatsoever)
- at first non-working, but starts working after some seconds
- (never seen before today) blinking amber, not charging, the macbook doesn't feel anything (no sound, nothing in System Information)
I work here since two years and before last month I had a 2015 mbp, everything worked fine until about a week ago.
Phone and iPad charging are all good.
I still have to see if other coworkers' laptops show issues as well.
Of course I always try and make different adjustments every time, such as unplugging the usb-c, then the magsafe, then changing the outlet, then changing with the magsafe disconnected... couldn't find any real solution.
