Mac Studio M2 won't boot - led flashes once

I have the same problem as the one described in this post: Mac Studio M2 won't boot - led flashes on… - Apple Community

The “Me Too” count is currently at 29 but there are no fixes available.

My Mac Studio will exhibit this behavior randomly: there will be cycles where I will be able to boot up successfully and cycles where I will not. The transition between those two states is a mystery.

It’s not linked to any external devices or specific plug, it’s quite capable of doing it on its own.

Apple has already changed the motherboard but I believe this is not where the problem is.

The problem happens specifically at boot time, something fails (or not) after the led flashes once.

If the boot process is allowed to continue then I hear the chime and it’s smooth sailing afterwards.

I am bringing it again today to iCare.

Any help would be appreciated.

I got my Mac Studio back from iCare. The power supply board was changed.

I checked all the power connections: the monitor one was a bit wonky,
Distributed the SSD disks to other devices: one to the monitor and one to the Apollo,
Disabled my Mac from going to sleep
Leaved it plugged and on all the time.

I am happy to report that the problem is gone and that my configuration is stable now.
