I would not mind using the solder iron to tweak inside, if you give me some clues, (of course it will void the guarantee) but these units are really sturdy.
BTW it is impossible in the environment I use the fit pc, to use a mini UPS.
One great feature in the first Slim Fit pc was the auto restart on power loss.
Is there a workaround in power failure so that the fit pc2 restarts without hitting the power switch on the front panel?
