MBP 13 2010 run slowly

[MDY]

Passed Asd and shows mpc error like attached file.
Need mpc replacement?

Continue on error to check for more failing sensors.

 

[MDY]

No Title

Yes, one more error. I tried another hdd and usb hdd. Same problem.

 

[dukefawks]

Check R5235/36 and R5260/61. If those are ok then it is most likely the MCP or SMC.

 

[MDY]

Battery appears like x. But if I removed it, it is still on.
You suspect ancient for first or second error?

 

[dukefawks]

Bad SMC I think. If PPBUS is 12.3V then replace SMC.

 

[MDY]

Yes, it is12.26V

But TN1D is SMC error or MCP error? Or could be both?

 

[jason_microsoldering]

Probably SMC in this case.

 

[larossmann]

SMC I/O means it can't communicate with the SMC on that line. Most likely SMC. Given the evidence that PPBUS_G3H is 12.23v, bad SMC.
