Introduction

Warning! If you have an older 3.0 Gb/s (SATA II) based system you need to make sure the drive you use is able to run at this slower speed. Review your drives spec sheet, make sure it clearly lists compatibility with 3.0 Gb/s (SATA II) systems. Most drives sold today are fixed speed 6.0 Gb/s (SATA III) which won’t work in 3.0 Gb/s (SATA II) systems properly.

What you need

Step 1

              Lower Case               
  • Remove the following ten screws securing the lower case to the upper case:
  • Three 13.5 mm Phillips screws.
  • Seven 3 mm Phillips screws.

  • Wedge your fingers between the lower case and the vent, and lift upward to release the two clips holding the lower case to the upper case.
  • During reassembly, carefully align the lower case and then press it firmly until both clips engage.
  • Remove the lower case.

Step 3

              Battery               
  • Whenever working near the logic board, it is always wise to first disconnect the battery to avoid short circuits.
  • If present, grab the plastic tab attached to the battery connector and pull it toward the front edge of the device. For Late-2011 models the battery connector will not have a tab and is simply a plug that inserts straight down into the motherboard–to remove pry the plug straight up.
  • If the plastic tab is missing, use a spudger to pry the connector up from its socket.
  • Pull the tab parallel to the face of the logic board.

Very easy, excepted for finding the right screw for Step 8. I replaced original HDD with a Samsung 840 EVO 500GB. Fine!

Exceptional instructions. If you’re struggling to restore from a backup… connect your backup drive via cable, start your macbook, choose disk utilities, choose the new hard drive from the list on the left, if first aide options (repair/verify) are not available, erase and name the new drive, and then you should be able to restore from backup. :)

Thank goodness you posted this. I thought I messed up installation because there was no new HD when I turned on the laptop. I couldn’t figure out how to restore. Then I saw this and tried it and it’s restoring now. Thank you!!

Very easy, Thank you for this tremendous guide. Works perfectly and I directly connected my old HDD to USB and restore all my information using the Migration Assistant app. Fine!
