4sns/1/c0000008 : taop -- 124

Hello!

Yesterday I've bought Macbook Pro 13 2012 without hard drive. When I installed it at my home, I faced with next trouble: system was too low and fans worked at maximum speed. And my macbook doesn't see battery.

I made AHT and got next information: 4SNS/1/C0000008 : TAOP -- 124.

Do you know what is it?

Update

I made full test in Apple Service Diagnostic and I've got next results:

zieevkamol, I believe your error code is referring to ambient temperature sensor (in your case most likely the HDD sensor). Check to make sure that sensor wasn't damaged somehow and/or that you plugged it back it.

Hello! Thanks for your answer!

But do you have an image of it? How can I find it?

And one more question: I removed HDD, but it doesn't change anything, problem is still existing. Does it mean something?

It should be the temperature sensor on your HDD not your HDD itself:-)

TA0P is for

Ambient Temperature Sensor

T = Temperature

A = Ambient Temperature

It is likely that your sensor is dead. OR, if you opened up the computer, you might have connected the connector in the wrong direction. I did not believe that it can be connected wrong way, but it did and I learned the hard way.

And, the names on the the board are not visible when the wire is connected, because it is written below the wire near the connector.

On Mid 2011, 27 inch this two wire connector (Ambient Temperature Sensor) is on the main board on the bottom left side near the fan.

Sorry. My English is not fluent.

I had the same problem: "system was too low and fans worked at maximum speed. And my macbook doesn't see battery".

My problem seems to be liquid damage. I have cleaned the main board with water and alcohol, and I have fixed the problem regarding speed and fan. But the MacBook doesn´t see the battery.
