Introduction
This detects the internal temperature of your machine for heat management.
What you need
-
-
Use your fingers to push both battery release tabs away from the battery, and lift the battery out of the computer.

-
Remove the three identical 2mm Phillips screws from the memory door.

Lift the memory door up enough to grip it and slide it toward you, pulling it away from the casing.
-
-
-
Remove the two 2.8 mm Phillips screws in the battery compartment near the latch.
-
-
-
Lift up at the rear of the case and work your fingers along the sides, freeing the case as you go. Once you have freed the sides, you may need to rock the case up and down to free the front of the upper case.
-
There are four plastic clips above the DVD slot, and another above and to the left of the IR sensor. These clips can be very difficult to disengage without prying. They can also be difficult to re-engage during reassembly.

Do you happen to know if MacBook Pro thermal sensors are normally open (NO) or normally closed (NC)? I have a dead A1261 logic board, and one of the thermal sensor connectors came loose from its two wires when I was trying to carefully pry the connector out of its slot in preparation for sending out the logic board for repair or replacement. The connector is so tiny, you literally need a magnifying glass to see what you're doing and it's a challenge to pry it out without accidentally causing damage. Since I already have the dead logic board out of the case, I will replace the thermal sensor before putting a new or repaired logic board back in. I was just curious if a MacBook Pro will boot and run without the sensor connected to the logic board? Presumably this would cause the associated fan to either stay permanently off, or permanently on, depending on whether the sensor is NO or NC, right? Thank you.
