    • You do not necessarily have to follow steps 3-6 to remove the battery in order to replace the hard drive. However it is recommended to remove all power sources from electronics before working on them.

    • Pull the battery cable connector away from the center of the logic board.

    • 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. Next, 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.

Excellent walkthrough! This was my first ifixit repair and I was able to successfully replace my damaged magsafe board. The 64-Bit driver kit was the perfect companion to this project and the many more that will come in the future.

Thanks for your help! I think something on the mainboard is toast and the computer is a total loss, but it was worth it to take a chance and see if the cheap mag board would fix it. Good guide!

Good guide - gave me the confidence to have a go - thanks - I would say to others be very gentle with the cable connectors - mine weren’t exactly the same type as shown in the guide - be patient and you’ll work it out.

I did the same procedure yesterday replacing a malfunction on magsafe board, just before signing up for Fixit and viewing this document. The walkthrough depicted here is really detailed and very well done. Excellent.
