Macbook M1 820-02016 Keyboard -Trackpad stop working after a while

That's another error.

Yeah figured. Took pcb out measured again with sensor in and keyboard in and it's 1.8v

Still does not work.

But in my case it does not work permanently.

last pic are these diode readings?

have 0.5v where you have 1.8v drop

That's another error.

yay it works, but when I connected to pin 2 on RC870 trackpad click doesn't work. so I check the schematic the click function also requires IPD_PWR_EN. so I decide to connecting pin (1) CC240 to pin (1) RC870 and now it works keyboard trackpad and also trackpad click.

so my question is, is it safe bro hoang sonw ?

Safe and error-free

Same problem. When computer goes to sleep via closing the lid usually, trackpad and keyboard dont work.
Either in the OS or recovery environment, suggesting it was not software related.
Reflowed the area that controls IPD_SPI_EN_CONN and just in case the lid sensor controller (same area)

Now 4 days and no more problem

After the waiting time, the IPD_PWR_EN rail is lost, causing the error TRACKPAD AND KEYBOARD to stop working.
Fix by borrowing the voltage of pin (1) CC240 connected to pin (2) RC870

A completely similar problem with the Mac, the keyboard and touchpad did not work when waking up from sleep.
I soldered the motherboard and it works. Thank you

Check if it is overheating. Contact Apple for advice and post your updates here.

Hi friends.
This model has a very weird fault.
Macbook Air M1 A2337 - 820-02016
it works for a while and after a few minutes the TRACKPAD AND KEYBOARD stops working
I already formatted, I already changed flex and trackpad. The error continues, I tried with another keyboard and the same error happens.
works for a while and then stops working trackpad and keyboard
(i rebooted and it works again, after a few minutes the failure returns)
THE BOARD LOOKS VERY CLEAN and IMPECCABLE

Thanks
