The new Macbook Pro 16" has problems with external displays connected to it, sometimes even just external hdd's or other thunderbolt devices. Do you have external displays connected?

It’s the polar opposite of the MacBook One / iPad Pro design. This is almost certainly the design since Apple controls the thermal and power envelopes strictly when on and off charger. I would avoid the delay of ...
