Power off and unplug your laptop before you begin.
  • Power off and unplug your laptop before you begin.

  • Turn the laptop upside-down and remove the following screws using a Phillips #0 driver:

    • Two 9.5 mm screws in the middle of the back edge, and one 9.5 mm screw in the right edge

    • Two 4.3 mm screws in the back corners

    • One 17.5 mm screw at the left edge near the optical drive

    • Three 4.3 mm screws in the front edge

screw assignments are definitely wrong. I swapped the red and the green, as per comment above, and kept the blue as-is.

Thanks everyone. It does seem like someone got their screws mixed up when they wrote this guide. I’ve made some changes as you all suggested, so the screw placements should be more accurate now. If anyone with this laptop could verify the screw measurements with a digital caliper, that’d also be very helpful.

Don't remove the ribbons, just move the keyboard slightly forward to remove the old battery and insert the new one (just make sure they are all connected when you put it back)

Now that the ribbons have been detached from the bottom cover, carefully remove the keyboard plate cover. Once it has been removed, place it in a safe and moisture free area so it does not get damaged.

Is painting your nails crucial for step 5?

Now, that is a stupid question! Of course! As I am working on 551M, I naturally have to have nails painted orange, with blue accents!
