The device got frozen and unresponsive under heavy load. It was forced off, and now won’t boot.
Things I have tried:
connected monitor and keyboard
hold the power botton to shut off, and press+hold ESC to power it on
unplug everything, let it set for hours, try again
So far no luck, nothing shows up on display, with only the fan running when powered on.
Has it become a good looking brick?

The fan turning on indicates power and BIOs functional. Please attempt system recovery steps here: System Recovery — DGX Spark User Guide
I tried that, but cannot enter UEFI.
If your DGX Spark is powered off, boot the device into UEFI settings by holding down the Esc or Del key immediately after powering on the device
