3 MacBook Shows no Response to Power
My 2016 MBP completely died the other day. When plugged into power I get no response from the laptop (display, trackpad etc.) No matter what charger/cable I use the MacBook never shows response to power.
Everything I have seen online recommend resetting the SMC or putting it into DFU mode and using apple config. I however could not do this because the MacBook shows no sign of life.
If anyone has any ideas to fix my issue I would appreciate the help!

DFU mode looks like the computer has no signs of life. The only reliable way of knowing if a computer was in DFU mode would be to connect it to another Mac running Apple's configuration utility which detects such things.
If you have the appropriate tools (bit driver with P5 and T5 bits, a black spudger, and a suction cup) you can open the bottom, disconnect the battery, wait about 30 seconds, reconnect the battery, and see if that helps.

Edit: I tried removing the bottom case and disconnecting battery. All symptoms remain the same.

Can you give us some history on drops, liquid spills or repairs.

@danj none - it has been cased for most of its life and never has had a liquid sill. It just stopped working one day

Where do you live does humidity go above 90%? If nothing works (could test continuity and logic board) could be the logic board. SMC handles resetting hardware components. I had same issue but charging lit up when plugged in and resetting SMC reset humidity sensors and computer started in AC.
If motherboard doesn’t light up or get power, psu or batt problem
