Got it. Last time I missed the two rear screws that were hidden by the bottom cover.
Any hints on getting the strain relief off the charging cables?
[edit]
Channel locks solved the strain relief problem. After all that I wasn't able to get any numbers of that diode to see if its the temp sensor. There was another similar looking diode on the output side of the fan. The raised diode was on the input side.
I was hoping for some kind of adjustment on the board, but I didn't see any trim pots.
I'll have to wait and see what tech support says before doing anything more drastic.
