Re: Entropy

another attack of entropy... I just got back from the market with two packages of day old uncooked chicken (marked down), and decided to throw it right into my slow cooker to not temp fate. Chicken can be nasty with bacteria.
Of course the only reason I am writing about this is that my slow cooker's internal microprocessor refused to boot up (again). The power company swapped out my meter for a smart meter this morning. The brief power interruption was not well received by the processor that apparently runs 24x7. When I cycle the power off and on again I get a brief flash of back light then nothing.
I tried several different secret handshakes (Like I would design in). If I hold down the on/off button and the up arrow button while cycling the power it boots up in some non standard state. Cycling power while holding down only one button does not work. Pressing any other button from the on, but not operating state wakes it up and it starts working as expected again.
This is already on my long to-do (someday) list, but hard to trouble shoot, when it is working, and with a cooker full of raw chicken is not an ideal opportunity to take it apart.
The likely culprit is a power on reset cap that most microprocessor circuits use. A faulty cap or bad solder joint could be the issue.

PS: Parts arrived to replace my car's 20 YO radiator hoses. I also bought new temperature sending units that I am suspicious of, maybe this weekend but probably not.
PPS: received my first phone call on my (porcelain) throne phone, mission successful.
