    • When handling the battery, avoid squeezing or touching the four exposed lithium polymer cells.

    • Lift the battery from its edge nearest the logic board and remove it from the upper case.

    • When installing the new battery, if there is a thin plastic film on your replacement battery, do not attempt to remove it. It is glued on and protects the battery pack while it is inside the MacBook.

    • If you're installing a new battery, you should calibrate it after installation:

    • Charge it to 100%, and then keep charging it for at least 2 more hours. Then, unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.

    • If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook's SMC.

i have problems with reassembly. how do i manage it to get the keyboard connector in the socket again? i can't make enough pressure to get it in

Hey guys,

just repaired my "old" 2012 Air's touchpad and thanks to your great instruction it took me exactly 30 Mins and was super easy...

Thanks for your great work!

@peter: yes, it needs a bit fiddling with the cables - just keep an eye on the flaps (they are closed on the new TP). Then it helped me to press the cable slightly in place with one hand and carefully pushing it in (moving it slightly left and right) with the other.

step 10 is not needed, in my second repair of this model I didn't remove it, this screw is only for calibration

Miguel Cartagenova - 返信

Right. Step 10 is not only not needed but should definitely not be done! This is a pure adjustment screw for the clickpoint. Only readjust there, in case clicking does not feel okay after a change of the trackpad. Usually no adjusment is necessary.
