M1 MacBook Air won’t power on

And people have reported no issues with third party docks too. Same here. My point is, Switch is USB C and Macs are USB C. So there seems to be issues with USB C and power. NEVER trust third party for powering systems. Regardless if it’s Switch or Macs.
Consumers don’t charge their laptop with $5 adapters. They get something from the Apple store that’s officially supported.
I get your point, I just don't agree with it. The problems are different. Imagine I bought a Switch years ago and used it with a third party USB C charger for years. Then I buy the newest Switch and pop it on the same charger, it bricks. Whose at fault here? Pretty obvious that Nintendo would be at fault here. However, you're saying that Switches died on third party chargers from the jump. That's a whole different situation than what's being reported in this thread.
If you can't ever trust a third party to deliver power to your laptop, something has gone wrong. Especially if the charger has been in use for YEARS. The hub that killed my M1 was a $120 USB C hub and has been in use for a while with other USB C devices, Mac, PC and Linux.
I'm not sure we know enough. The testing conducted for the Switch the I linked to earlier suggested that it was mainly one 3rd party dock that was responsible, but many (most?) others were getting tarred with the same brush.
The fact is that Apple must've shipped over a million of these M1 Macbooks at this stage, and nowhere near enough (yet!) are bricking for it to be possible to nail it to Apple's implementation of the M1. The PD standard seems to be quite complex, with a large variety power levels and voltages supported, so it's possible that a dock which works with one client doesn't play nicely with another.
We could do with someone, like in the Switch dock investigation video I posted above, taking a bunch of these docks, and testing them for compliance at the power levels the M1 asks for. And while they're about it, checking that the M1 is following the spec properly and asking for the right power levels.
In the meantime, I think when my machine arrives, I'll be powering it exclusively from the supplied charger till this is eventually bottomed out.
This is my point though, the hubs in question have been "playing nice" with all other USB C devices. Heck, I even used these hubs to charge my iPad Pro. The implementation of USB C PD didn't change in the hubs. There's only one spot it changed in my equation....
So I guess even if this is an implementation mis-match, Apple, the device manufacturer, obviously didn't do enough testing to validate that their implementation was able to function in the real world.
Really hoping it's just a bad batch of devices because in all other ways, this laptop is FIRE!!

I agree with that, but i think that i was some post when even not using hub with charging through PD, ended up with bricked macbook. So i'm awared that it can brake mine once again when i will only get it back.
This a hundred times over! Maybe we should be asking people for a rough indication of serial number and maintain a register here (if that's allowed under the AUP), since this seems to be the most active Apple site on the web right now.
If it turned out it was the first couple of batches that came out with a missing zener diode or something to protect against overvoltage, then we might all relax a bit!
From the digging I did on the Nintendo dock problem, it looked like the chip responsible sometimes took the abuse for a while before then failing. We again don't know quite enough - but we could do with hearing from anyone that had that happen and ask whether they'd ever used a dock, which might cause latent damage which then fails a while after.
No they are not. Third party chargers are a problem here. It’s all issues with the messy USB C spec. How is it different? Both systems charge via USB C. Which should adhere to charging standards. Yet there are cases where it is bricking. There are cases where there are no bricking. So again, seems like the USB C charging spec is a mess. Therefore, it is best to only rely on official supported charges.
Also using third party chargers have been bad news from the beginning of laptops. I have had several Lenovos brick due to using unofficial chargers.
Or you can just check when your MB was made here: Click me!
Serial number could be too much info like you said. Mine was made on 30.11-06.12 of 2020
Hey, so I have watched this thread for a while and wanted to give me experience.
I had (probably) the exact issue with my 2020 MBP 4 times. After the 2nd time, Apple no longer wanted to respect consumer laws (German or European) so I ended up selling it on eBay for way less. The support representatives where not helpful at all, kept hanging up or didn't hear about consumer laws, even though they are quoted on their site.
The issue seems to be with the T2 chip, which should be the same with the M1 models.
To test my assumption, one could try to get the M1 into DFU mode with a second T2 MacBook and try to restore BridgeOS using the Apple Configurator 2. The MacBook should show up and the restore should start. However, some have reported that this rescued the MacBook. However, in many cases, the MacBook's logic board is simply fried and needs to be exchanged.
So the most interesting part in my opinion, is that this issue has not started showing up with M1, just raises more often with M1.

Since M1 Macs do not have any T2 chip, that is not the problem.
Source: https://support.apple.com/en-us/HT208862 (They are not listed as having the T2 chip on Apple's site, and when you go to System Information on an M1 Mac, there is no mention of the T2 chip.)
I’ve had my MBA less than 3 weeks. Today I was using it plugged into my LG monitor with the usb-c cable that came with the monitor when both screens flickered and died. Power key won’t turn it on or off. Called apple support and they had me try to start it with 3 different key combinations and none worked. I have an appointment at the nearest (1.5 hr drive) apple store on Saturday. Until it’s fixed I can’t work.
That's rather troubling. Presumably that LG monitor charges it too? I don't suppose you feel like putting your serial number into the site that dgtvc shared above to see when your MBA was made? I'm assuming it's an M1-based MBA?
At this point in time, I would not leave a hub connected to the M1, especially while charging.
Yeah, T2 chips were only in Intel Macs. That feature is integrated into the M1's SOC.
I think that is an overreaction. There appears to be a relatively rare manufacturing defect on some M1 MacBook Airs that cause it to fail fairly quickly after a PD hub is connected. It certainly isn't all MBAs.
Edit: I personally would want to know that it is defective sooner rather than later. I've had a Caldigit SOHO USB-C dock now for almost a month and use it every day with Power Delivery. It has been fine.
I didn't suggest it was all MBA.
There have been a lot of people here reporting the same kind of problem. My point was, if one doesn't want to risk having their M1 go down, and be without any machine to work (or play) etc. try and mitigate the risk by not leaving a hub connected to the M1. That advice may or may not work but, there are some here who probably shouldn't risk it.
I never buy AppleCare, but I’m considering that given the situation, it may be wise getting it this time. Before the 60 days allowed for getting it pass.
I’m interested in getting opinions.

As has been said in another thread I buy Applecare+ for anything that moves about on a regular basis.
It seems that it might be more appropriate than ever with an M1 on its way
USB-C PD spec was a mess and I had hoped something has changed in the last 4 years. Judging by this thread it could still be a mess. I am reminded of this story from 2016.
A Google engineer sacrificed his Chromebook Pixel to test USB-C cables

Technically, yes they still do. However, it is embedded into the SoC. So my point and findings are still valid.
