NO CPU temperature reading on and off, logic board faulty?
I noticed my MBP had been really slow lately sometimes, the problem got worse and worse overtime. Kernal_Task has been using up the CPU even without any loads. I thought my MBP was dirty, so I opened it up and found the battery expanded very badly, although it only had 20 cycles over 3 years of usage. Trackpad was very stubborn and I had been wondering why, the battery crooked the frame.
I went ahead and bought a replacement battery and had it replaced. The problem is still there.
I noticed when this happens, CPU Temp from Core 1 - 4 are disappeared, as well as CPU PECI and Intel GPU.
As soon as the temp readings come back, kernal_task goes back to normal.
Did the expanded battery cause damage to the logic board ?
Is a repair even worth looking into?
I've tried resetting the SMC several times, still the same result.
I just took it apart, will re-apply thermal grease tomorrow and see what happens.
with the new 2016 MBP refresh coming around the corner, i just want this MBP last a little longer.
Here are the screenshots of the temperature readings.
Is this a good question?
