Greetings,
A while back my 280R started powering itself off at random, usually a short
while after being powered on. Through the RSC, I found out that one of the two
CPU modules was reading improbably high temperatures that varied wildly, and
when it would hit an over-temperature condition, the machine would halt. I
removed the offending CPU and the machine is working now, but I can't figure
out how to repair this thermistor issue. Is there a discrete thermistor on the
CPU card or is the temperature measurement performed in the CPU die? I'm
hoping the processor can be salvaged.
Best regards,
