LattePanda Alpha2 i5 8210y Not Powering On Issue

Hello everyone,

My LattePanda Alpha, which has been working flawlessly until now, suddenly stopped booting. I suspect it might be related to a static discharge issue. Currently, neither the Red nor the Blue LEDs are lighting up; only the fan starts spinning as soon as power is applied.

Steps I have already taken:

BIOS Re-flashing: I re-programmed the BIOS, but there was no change in behavior.

Voltage Rails: I measured various voltage points (5V, 3V, 9V, etc.) on the bottom of the board, and they appeared to be within normal ranges.

EC Component: As a last resort, I suspected a faulty IT8110E chip and was preparing to replace it.

New Finding: Today, after removing the fan and the CPU heatsink, I measured the voltage values around the IT8110E. I observed a reading of 1.18V on the component marked in the attached photo.

Is this voltage level normal for this specific part of the circuit? I am looking forward to your technical guidance.

During my investigation, I have identified the root cause of the issue, although the exact source of the failure remains unclear. I have confirmed that there are no hardware or firmware issues with the IT8110E chip itself.

The problem is specifically related to the 3.3V power rail:

The VCC (Pin 16) and VSTBY (Pins 4, 7, etc.) of the IT8110E are tied together on the PCB as expected.

According to the datasheet, these lines should be at 3.3V; however, I am only measuring 1.18V at these pins.

The 3.3V rail is active and stable at other connectors on the board, but it is not reaching the IT8110E correctly.

Validation via Bypass: To test this, I manually jumped the 3.3V power from a stable connector on the board directly to the VCC pin of the IT8110E. With this bypass, the LattePanda booted successfully, and Windows loaded without any errors. You can see the details of this bypass connection in the attached photos.

Request for Assistance: It appears the 3.3V power is failing to reach the IT8110E. Could you please provide guidance on:

The specific path and components the 3.3V main rail follows to reach the IT8110E?

Which specific components (e.g., LDOs, resistors, or load switches) along this path should I inspect for failure?

Are there any specific test points or common failure spots you recommend measuring?

I am looking forward to your urgent support to finalize a permanent repair.
