Javier zoomed in. A note, scribbled in the digital margins by someone who signed as "K.C.," read: “Valve controls bidirectional memory bleed. Updated to v2.1 to patch exploit where user could overwrite host’s past. Patch failed. Do not energize.”
Shorted ceramic decoupling capacitors near the CPU buck converter or the discrete GPU power stages.
Always check these standby rails first. Look for shorted capacitors around the PWM IC.
