Hi everybody,
ASD shows: An issue with the battery (which is not reconizable), tried with various batteries, same issue - ERROR - 22 (Battery Error Condition Set)
An issue with Thermal Interface -Processor: Processor0: TIM Test Percent GB (test #4) - TIM Test 75 percent GB - Check that CPU heatsink is properly attached, using product spec theta dh + 75 percent guardband
ERROR - 255 (Unknown result-code 0xff) - TEST FAILED

The heatsink is obviously well attached.
Any ideas? Thank you

If the battery is not recognized it will run slow. This model requires an A1405 model battery. The thermal error should be ignored, your problem is in the battery or no communication with battery.

Let`s make some clarifications: The battery is not recognized on OS X (various batteries), ASD OS and EFI were ran with the said results.
​Thanks

An update: ISL6259 was replaced, the battery is now recognized on OS X but still not charging, the Mac is STILL slow as hell

What battery model are you using? Must be A1405. What is OSX saying about the battery, cycle count and status, etc. Also run EFI ASD and check for errors.

The battery model is A1405, OS X 10.11, OS X recgnizes the batterie and says "Replace Now", 530 cycles. Again - that was tested with various batteries, all from the same model A1405. ASD EFI and OS still show the same errors as above. Further help will be appreciated
