Haptic feedback from the track-pad only, not power cycling, no fans or display at all. I have tried multiple chargers and cables. Tried disconnecting the battery as well. Also tried disconnecting track-pad, speakers, and touch bar. When I get haptic feedback I can hold the power button and it will turn off, and when I hit the trackpad again it does the same thing. I do have a USB-C tester thing and a multimeter. Can anyone help me with this?

Any history available?
Be aware, if battery is empty, or not connected, this board requires 96/140W charger to turn on.

USBC meter is very useful; it shows if charger switches to 20V and the current consumption of the board.
Discard 87W charger, is not good for this board.
The charger cable is also important, as for 100W (or more) the cable must be electronically marked.
You can test with a working MacBook, if the charger is recognized as being 140W; if not, find another cable (Amazon, Aliexpress).

How do I see if it is recognized as 140W? This thing has no instruction manual. Ok I found an online manual. Still stumped. But I don't think its a charger issue. It behaves the same with and without battery. https://manuals.plus/ae/1005009240609543

It is listed on System Report.
You should get a battery holding some charge, for proper test.
Trackpad haptic is not a signal of booted board.

It says
Wattage (W): 94
Name: 140W USB-C Power adapter
Charging: Yes
And it shows a serial number. Should it be showing 140W? I did order some 240W USB-C cables that should be here within a couple hours.
I know that haptic does not mean its booting, but it does the haptic with and without the battery connected. And it has been running on battery overnight. So the battery is not necessarily low.

Charger looks like properly detected.
Do you get voltage on any big coil?
What is PPBUS_G3H voltage w/ and w/o battery connected (charger present)?
