Memory module 1, heatpipe input and output temperature 128 and ts0p

Hi i have an old mid 2012 a1278 md101,

I have high CPU usage and fans at full speed. Checked with hw monitor the memory module 1 and heatpipe incoming and outgoing air temperature is 128 degrees Celsius which is definitely incorrect. On running ASD EFI it shows ts0p sensor failed - SMC I/O failed.

I would like to know how to fix this, I can resolder if needed and have a donor board but how is palmrest/trackpad sensor related to the memory module and heat pipe sensors.

Also i have cleaned the entire board and could not see any signs of water damage. Post that cleaned the board with IPA and a brush.

installed a spare battery i had.

Your system is fighting its self! The high CPU and RAM temps are telling me a process is struggling to work properly. Often I find this condition on a system which had its HDD upgraded with a SSD. It can show up right away or a bit later. As the I/O data flow between the logic board and the drive is where the issue is! Either the cable is shorting out, is of the older SATA II generation or when it was fitted in the cable was damaged

Reference: Your Hard Drive Cable Is A Ticking Time Bomb

To start with I would replace the MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable. I would also apply a single strip of electricians tape of the upper case to prevent the cable from chaffing on the rough aluminum surface. When fitting the cable I would not crease it as that damages the thin foil wires within it.

You may also need a new Trackpad Flex Cable as the ts0p sensor is within it.

The cpu temp is fine its hardly 40-50 degrees the error is heatpipe incoming and outgoing air temp, same with memory i have tried different ram sticks and shows 128 for all of those. Tried a different trackpad and its the same slow system with incorrect temperature reading for the 3 above mentioned sensors. Also i have tried booting the mac off an external harddisk and the system was still massively slow and same temperature errors. So not sure if the sata flex cable is the culprit here.

@Anusheel Dew - Then you are struggling with SMC putting your system into CPU Safe mode. Lets get a better read of things here install this great app TG Pro it's by far the best way to see your sensors and fans. We only need the free version here. Take a snapshot the apps main window making sure to capture all of the sensors (you may need to alter the windows size to fit them in one snap of just take two sliding the slider from the top down to the bottom. and post the output here Agregar imágenes a una pregunta existente

So something weird happened, i opened my mac today to see if i could see any water spills or damage and pretty much closed it back without disconnecting any connectors at all and the temperature reading is normal for the three sensors now all of a sudden no idea how, but now the system sometimes does not start and gets stuck on a white screen with a partial bootchime and sometimes i can hear the fan ramp up but the display does not turn on, i’m pretty positive something is massively wrong with the logic board or could it be some stray metal piece in the casing shorting something out And on opening and looking around the macbook that stray metal moved someplace else?

@Anusheel Dew - Take the logic board fully out and using a small soft paint brush carefully wipe down the board and I would also do the fan blades and heat sink fins, and intercase areas while I'm at it. Then use a can of can'ed air carefully blow the junk away.

Make a full inspection of both sides looking for corrosion, solder specks, burnt or discolored components. If you see something post a picture or two so we can see it clearly Agregar imágenes a una pregunta existente

Hi

For now I would listen to @danj

But one of my Dads friends had this issue and It was a microscopic amount of corrosion on the SMC so maybe check that out just to rule it out

I would flush isopropyl alcohol under it just in case

But definitely listen to what @danj has to say as from what previous comments have said on this post he has seen this issue in more forms that I have

Thanks:-)
