I have a 2020 MBA M1 and it was working fine until a few days ago. Now when I try to close the lid, it does not go into sleep, and when I open the lid it also doesn't wake either, I have to press a button. Also when I plug into an HDMI display it does not go into clamshell, instead opting to mirror the screen thus leaves the build in display on. I have made Apple Hardware Diagnostics test and all seems fine, I also checked ambient light sensor and it's working, is this software related? How can I solve it?

Did you install any utilities that manage system sleep by chance?

If not, I wonder if the magnetic sensor that detects when the lid is closed/open went bad.

I recently installed CleanMyMac X but I doubt it had that kind of effect. I am starting to suspect it is a magnet issue. I did a full reset to factory settings, erased disc, reinstalled the OS but the problem persists on both Monterey and Ventura. Must be a hardware issue. I might take it to the Apple Store but any chance I can fix it on my own, I don’t know.

Sounds like hardware issue to me too.. Seems like that one is pretty rare.. So you didn't drop it or spill anything on it?

I am very pleased that my MBA M2 does not go to sleep when Lid is Closed and my external Monitor is connected.
That is called "Clamshell Mode".

But i have configured sleep after 3 Minutes.

Also there is a chance that other things preventing Mac from Sleep if you have not connected an external Monitor:

  • China USB Hub
  • AdressBookSync on iCloud

Just open Activity Monitor and sort "Prevent Sleep".

or enter in Terminal:
Bash:
log show | grep -i "wake reason"

Takes some time to show entries.

Probably unrelated to the issue but there's your first mistake.
So I have seen… Never would I dare install that ****-ware again.

As for the issue, no, I took it to an Apple licensed repair service (not Apple) and they found no hardware issues, just reset it and sent it back, which I had already done. I am guessing it is a hall sensor related issue, I’ll take it to the official Apple store as soon as I can.

I've never had it do anything bad to mine, yet.. Let us know what happens at the store.

So.. I went to the Store. They did some tests and told me hall sensor is not working properly, offering me a screen replacement which I agreed. They changed it, but the problem was not solved and told me this time that the motherboard was faulty. They had seemingly already ordered the part by the time I was informed and would change it as soon as they have it. In the meantime, I asked for a brand new laptop since I believe this one is chronically faulty but they refused, citing Macs are not “replaced”, parts are. I don’t think that is the case elsewhere but we’ll see what happens next. I am feeling a little distraught.

Yeah that is one of the problems at apple store...depends on who you get and what mood they're in..IMO.. Well, make sure you document what serial number you currently have and when they replace the MB make sure it's also documented. I don't know if they change the SN to be what the original was or not as I've never had to do that. Make sure you document everything. If replacing the MB doesn't fix it I would demand a total replacement. This does seem to be a strange issue.
