M2 Studio 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.

Having had the logic board replaced a few months ago my M2 Mac Studio is again failed to boot. I've been able to boot up successfully after several attempt up to now but now it's no longer booting.

I've asked Apple for a new machine as this is work critical machine but they've sent me back for another repair - last repair took over a month.

I don't believe changing the motherboard will resolve the problem and I'm surprised this hasn't been raised as a larger issue since SO many people seem to be having the same issue.

If replacing the mainboard does not solve the issue, they need to replace the power supply.

Calling it a design problem merely deflects attention away from the acute problem you are facing and makes Apple employees defensive.

As I pointed out on that other thread, you are not talking to Apple when you post here, only to other Users.

The power supply was tested extensively as was the logic board. The only solution suggested was to replace the logic board, it's clear it has power or it wouldn't be attempting to start up.

You're clearly missing the point that there is a significant issue, people have purchased these machines at significant cost and now they are failing in the worst circumstances.

The post is to notify other users regarding this issue - seems as if you prefer they were aware of it?
