Hello friend
This problem is characteristic of the north bridge chip BGA. Do reballing chipset, and probably solve the problem.

I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.
Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:- Verified that all critical voltages are present:
- 3.3V and 5V are always present if DC is plugged.
- 1.8V on the BIOS chip is present.
- Checked the power button functionality:
- When pressed, the voltage drops to 0V, indicating the button is functional.
- Inspected the flex cable connecting the USB, audio, and power button to JUB1:
- Confirmed connectivity is intact, ruling out issues
