Yes, Dan, I did. Tried both. No avail. Mac reboots after 3 secs. Brand new.

* Laptops with the T2 chip: Shut down. Press and hold the power button for 10 seconds, then release it. After a few seconds, press the power button to turn on your Mac.
* If this doesn't reset the SMC, shut down. On the laptop keyboard, press and hold Control-Option-Shift (your Mac might turn on). Hold these keys for 7 seconds, then press and hold the power button. If your Mac is on, it will turn off while you hold down the keys for another 7 seconds. Then release the keys, wait a few seconds and turn on the laptop.
@Vlad Hans - Thats what the Apple T/N stated ;-}
