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

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

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

no the same problem with a functional battery. What is the Thermal error? Regards

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...

Sure, of course.

The board turns on with it connected and after 10 seconds turns off

Any idea where to start? power lines are all fine.

It's not, we have tested it with different all working batteries

Thanks for replying. The board has experienced water damage, was ultrasonic cleaned and shows no visible signs of oxidation. Battery is recognized in OS X and shows no faulty alert. Measured voltage on PPBUS_G3H with the charger connected and battery disconnected is 6.7-7.3 V

Doesn't turn on without charger. After turning on with a charger connected, when disconnected from the charger works perfectly on battery. Any ideas? Thanks guys.

Hi fellas, No response WHATSOEVER when trying to turn on - no sign of life. First 2 red diagnostics indicators (CPUA + CPUB) are always on (with / without the CPU board) BUT when the front panel board is disconnected - those 2 indicators turn off. When DIAG LED button is pressed only 5V STBY...

We will make enough noise online that it will bring them enough negative PR that they would drop this bullshit, we are in this together.

no the laptops work with new batteries. It is a specific problem with this specific mid 2015 battery.

i'm talking about the battery, the laptops themselves are all fully functional

Yes please check if it switches to optical(look into the port, if the red optical lamp is on). sometimes that is it.

The OS doesn't even see them, doesn't even recognize nothing. really weird for me, tomorrow a customer is bringing me YET another mid-2015 with battery that is not being recognized

Have you checked the headphone jack?

It seems like every single 020-00079 that i get to touch stops to work all of a sudden. they all have similar symptoms, full charge(12v) on direct battery pins, but after the battery controller board it is down to ZERO. Do these batteries have a kill-switch that kills the controller as soon as...

Yes it does turn off as soon as you unplug, Weirdly Q7155 has a lower voltage on the other side of diode than it receives, on the working board i have 8.35v on pin 5 and exact same 8.35 on pins 1, 2 and 3. on the broken board its 7.9v on 1,2,3, instead of 8.35. also on pin 4 i get 1v on the...
