    • In this step you will disconnect the battery to help avoid shorting out any components during service.

    • Use the flat end of a spudger to pry both short sides of the battery connector upward to disconnect it from its socket on the logic board.

    • Bend the battery cable slightly away from the logic board so the connector will not accidentally contact its socket.

    • Use a spudger to help lift the free end of the SSD just enough to grab it with your other hand.

    • Do not lift the end of the SSD excessively.

    • Pull the drive straight out of its socket and remove it from the logic board.

    • When reinstalling the SSD, be sure it is properly seated before reinstalling its retaining screw.

I think my fan makes some noises when my laptop is cold in the morning... Cold means 18°C... Is it dangerous?

After a few minutes or even seconds, the sound stops.

I’m a 21 y/o college student whose laptop fan was being too loud to use in class and I decided to take matters into my own hands so I took the risk of completing these replacement instructions and I’m so glad I did! My laptop fan no longer makes noise and I didn’t have to take it to Apple and have them overcharge me for something simple enough for me to do at home. Thank you!!
