The touch pad controls cursor movement and is one of the most used parts of the laptop. It is exposed to frequent wear and tear and may need replacement.

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.

correct, swap the green and red

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.

Use the plastic opening tool to separate the keyboard plate cover from the bottom cover. In order to do this, insert the plastic opening tool in between the keyboard plate cover and the bottom cover, then slide along edges to pry open.

  • Locate the three ribbons connecting the keyboard plate cover to the bottom cover.

Добавить комментарий

  • Invert the laptop in order to gain access to the ribbons.

  • Remove each ribbon by flipping the small white plastic flap up and gently pulling on the ribbon.

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?

Yes and you have to put lotion on

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!

  • Using the Phillips #0 Screwdriver, unscrew the 5.5 mm Phillips #0 screw that holds the spacer in place.

this spacer may be a cd rom drive or potentially a second storage device like an ssd or hard drive. Either way the process is the same, remove the single screw, and slide to the right.

Josh - Ответить

  • Remove the spacer from the laptop by gently sliding it towards the right edge of the laptop.

  • Remove each of the two small antenna connections by disconnecting one wire at a time. Each wire should easily unsnap from the Wifi card.

mine only had the black cable and the small wifi card was slightly different. the card itself has two available connections and is labeled as to where the black cable (main) and white cable if it were present (aux) cables connect.

  • With the Phillips #0 Screwdriver, remove the nine 5.5 mm Phillips #0 screws which hold the motherboard in place.

there is one more screw that must be removed at the bottom right corner of the motherboard, just out of view.

Josh - Ответить

  • Now, locate the two wires connected to the motherboard.

Добавить комментарий

  • Remove the wires by easily pulling them parallel to the motherboard's surface.

  • The wires are very fragile. Be sure to pull carefully so that they do not break!

  • Remove the LCD display connection by gently pulling on the attached wire.

    • Gently lift any tape that may be holding the connection.

If the tape is removed when disconnecting, be SUPER sure that the connector is the right way before reconnecting. I managed to brake this connector by putting it in the wrong way! Both sides look very similar.

Eric Serra - Ответить

I agree with Mr Serra - you wouldn't need to touch the Motherboard/hard drive.

Jane Armstrong - Ответить
