My macbook air m1 goes to a strange mode sometimes, when it wakes the external monitor every 45 seconds... You can see it in the "pmset -g" log:
I have a feeling that this stops when the battery is fully charged... I have tried to turn the optimized charging off but it did not help... It's driving me crazy, the monitor is turning off and on constantly.
I have it connected to OWC Thunderbold hub and USB-C - DP cable (LG 4k 27")
I have disabled tcpkeepalive and powernap in pmset (though as I understood powernap can't really be turned off)
Pmset assertions don't show anything suspicious
It behaves the same when I turn off the USB3 hub where I have connected the devices listed above, so it is not caused by them...
Any ideas what this could be caused by? The only discussion about this I found is on this chinese forum - translated-link
It's also mentioned here, but with a different wake cause - macrumorsforum
