Customer brings in this embedded PC DE67-N1-7200 made by Giada (Giadatech). It's completely dead. Just a little over 2 years old and just out of the extended warranty he purchased.
Was only drawing 20ma, no response to power button or the CMOS reset button either on the front panel. Quick check around the coils showed PL9 was shorted to ground. As I didn't have a schematic, the location of the PL8/PL9 seemed to indicate these were for +3.3V/5.5V. Perform voltage injection and thermal camera. Was hoping it was a cap, but alas, it was another Intel CPU with shorted PCH. Guessing at this point PL9 was for +3.3V.
Manufacturer subsequently provided the schematic (maybe because this product is EOL). Motherboard part number is JHS61E-10. Also confirmed that PL9 was +3.3V. Attached is the schematic and some pics if needed for anyone in the future.
Got to say though, they were pretty co-operative in giving out a schematic. Hats off to them.
