Kernel_task causing immense slowdown when bottom case is on
I’ll try and make this short but this is a LONG journey with a ton of information. During a tune up (cleaning dust and installing new RAM and solid state) in my 2010 macbook pro, i forgot to unplug the battery before i began work. This ultimately fried the backlight fuse and an inductor and capacitor on the WLAN circuit.
After repairing both i power on my mac and it is INCREDIBLY SLOW-like unbearable, the fans are also at maximum speed. I check activity monitor and well
kernel_task is using litterally %600 of my cpu. Kernel_task is a process that takes away from other processes to reduce cpu temperature to prevent overheating , its part of macOS. My issue is the computer is litterally almost idle besides entrcheck.
i know my hard drive (technically actually a solid state) isn’t failing because its brand new. The Ram is also a known good component.
The twist: this all happens when the bottom case is on, if i remove the bottom cover and start the computer, it boots and runs like a dream. Im so confused and frustrated ive been at this for days now.
what ive done
reset SMC, PRAM, Swapped Ram and Hard Drive, spent hours on this doing research, please help, ive spent so long trying to get this thing up and running again. Id hate to just give up, but i dont know what else to do.
after running the same diagnostics (TG PRO and Entrecheck) here are my results WITHOUT the back cover on
UPDATE UPDATE 10/26/2021
upon putting the back cover on, and taking it off and noticing the difference. I see the the palm rest temp sensor (located inside the trackpad flex cable) does not respond with the case on. This part has been ordered, will update after replacement.
Questa è una buona domanda?
