Mac died overnight. No boot

Machine came in dead. Was working fine last night with the charger plugged in. Dead this morning.

I opened machine and logic board is visually fine. Changed charger known good one. Disconnected battery and charger, pressed the power on button for ten seconds reconnected battery and charger, with no results.

Hooked up USB C meter and getting no readings from right side ports. Am getting a reading of

20.4 v 0.04 to 0.06 a

33 mah on left side ports.

But the meter came with no instructions. Jokitech, the manufacturer apparently no longer makes the devise so I have no idea of what the reading mean except for the 20.4 volt input side.

It’s been plugged in for an hour and still no response when pressing the on tab.

Any ideas on where to go from here? @danj

Did you plug in the charger into the meter and then into the system?

@dan Yes, I did.

Here are some things you can try - 1) With the bottom plate removed and the battery disconnected, disconnect the trackpad flex cable from the main logic board, then connect a known good charger (preferably Apple branded) and press the power button. Watch the fans to see if you get fan spin up. 2) If disconnecting the trackpad doesn't help, try disconnecting the display from the logic board as well. 3) If that doesn't help you can continue disconnecting non-essential components until you isolate the effected parts.

I ended up sending this one to Rossman. They fixed it for $425.00 but would never tell me what they fixed.

Did you take a look to see if you can see any signs of work? Sadly you would need to lift the logic board out as the TI chip I'm suspecting is the issue is on the back side.

@dan no I didn't look as my customer was unhappy that it took so long to fix. Didn't make a dime either.

@mayer - Sorry guy ;-{

The newer Mac's are becoming more throw-away every release.

I guess its the drumbeat of progress as the other PC makers are following Apple's lead.

Do you remember the slide ruler and then the mechanical calculators of the 1950's and then when the Bowmar Brain LED calculator came out and then soon after HP units with programable units! Now the simple ones are throws at trade shows and the cost of even a desk unit is less than $20, the Bowmar cost $200 and when you add in inflation its around $1,500 today!

Many people don't remember the past and how things changed and how our lives are ruled by the waste we have created in the pathway to now.

@danj My slide rule still works fine and no battery to run down, but I must admit I have not used it in years. Maybe it's value as an antique will enhance.

@mayer - I've also stopped using mine too. It sits in my desk drawer just itching to show me its magic! And yes no fangled batteries or charger to worry about.
