Why is my CPU running over 100% and AHT gives 4SNS/1/40000000 TsOP--124?
My MBP ran without any issue until 2014 mid and then it started to make fan noise(running at 6200rpm), and fans were always running. Then it started to give charging issues. When I plugged my charger in it quickly blinks amber and then goes out and will not charge the battery. But some times it charged the battery. Now Machine is very slow and kernel task is always over 100%.
When I ran AHT it gave 4SNS/1/40000000 TsOP--124 error. And TG pro shows all the sensors in working condition, but PalmRest sensor is not showing in the list even.
I am helpless at this stage and here I don't have apple stores to repair this. Apple reseller in here telling me to replace the logic board without inspecting this issue deeply. I want to find whether a failed thermal sensor cause this problem and if it is, which one is the failed one(Palmrest/Optical drives/Power bus).
I de-assemble my MBP to check that upper case keyboard ribbon cable and found this. One of the Capacitor or Resister(I can not identify the item) is burnt, is it relevant to this issue. Please give a look and advice me.
Is this a good question?
