Macbook Air M2 Lid Angle Sensor Issue.

[Instafixx]

When we close the LID, the device goes off to sleep. But when we open the lid the machine restarts and turns back on.
I got the LAS changed from Apple. Still the issue persists.
Board is clean.

Even if we dont close the LID. if the device goes to sleep the same thing happens.
Even with LAS disconnected this happens

Did you try DFU restore?

 

[Instafixx]

No. Let me ry

Did DFU restore . Still the same.
Once DFU restore is done the sensor doesnt work. Put the machine to sleep manually. It reboots. Port Reboot now the LAS sensor works but the issue persists - not everytime - but happens 2nd or 3rd Time. i Have attached the kernel panic as well.

Tried another macOS version?
Change security settings accordingly and boot another macOS version from USB.

 

[Instafixx]

The machine went to sleep and rebooted during the OS installation process as well.

 

[2informaticos]

Disconnect internal LCD and test with external monitor.

 

[Instafixx]

With Internal Screen Disconnected. I am putting the machine to sleep manually and it wakes up just fine.
LID open close wont work now. But manual sleep and wake is fine. Tried 2-3 times.

Test with known good LCD assembly.
