2020 Intel Mac no longer does clamshell

[Donut417]

Was working fine before I went to the grocery store. Turned of my mouse, keyboard and tv went I headed out. Came back and turned it all on, the TV will display for 10 seconds or so and acts like the MacBook goes to sleep. The TV can detect when I unplug the HDMI as it shows a different message. Keys on the keyboard and clicks with the mouse wake the computer for 10 seconds. Computer works fine with screen when I open the lid. 
 

On the latest version of MacOS 12. Tried my cheap USBC dock as well as a type C to HDMI adapter. Keyboard connected via Bluetooth, mouse is a Logitech MC anywhere 3 using the USB receiver. I have restarted the computer. To be clear this setup has worked fine for months.

My memory is they like to do sleep cycle stuff with magnets.  Maybe the permanent magnets were unmagnatized by something and the Mac is still throwing “I’m asleep” vibes?  Kinda wildly unlikely I suppose. I don’t know if the thing would have updated when you were away or not.

Well it randomly decided to start working. Im not sure what the hell is going on. Sometimes Ive seen this thing do some weird shit. Hell I recall a few times I just didnt want to charge. I would have to reset the SMC and such.

*hopes suddenly getting up and dancing qualifies as ‘weird shit’.  It is a laptop after all*

 

”analog” type problems bespeak soldering issues to me.   I used to have problems with apple laptops with the gigantic barrel power connector having problems with the female end getting literally ripped off the motherboard by a casual kick at the cord.   Had to solder that back down like 3 or 4 times.  Maybe an apple “genius” would have something to say.  They do see a lot of them every day.

The magnets are a killer. On non Mac laptops too. Had a string where my fiancé’s laptop(non Mac) would randomly go into sleep mode. I was at work so couldn’t see what exactly was going on. 
turns out she found the exact spot to put her phone to put the laptop to sleep. Turns out it used a magnet to sense when it was closed. Apples mag safe is strong enough to trip that.

So next time I should buy the Mac mini. Good to know. LOL. I mostly just use my MacBook in clamshell mode with my TV. So I guess when this computer dies Ill likely go to a Mac mini.

If it’s a magnet came loose problem it will be glue not solder. I can see the thing having to come apart to fix it.  Huge PITA, but doable.  The things are usually in the hinge.

I got Apple Care until May 2023. If its an issue Ill get it repaired. Right now It seems to be working. Also, I would the magnet come loose if the machine is not moved much and always in clamshell mode?
