Anyone else fried a System76 Launch keyboard?

It’s getting cold out there. Walking static build-up. Discharged. The Launch Heavy is lit! The keys forever glow, but the message never comes through.

Anyone fry one of these?

no, but the PCB is open source so grab a multimeter and do some failure analysis.
