Introduction

The Asus X551CA power button allows the laptop to turn on and off. If it is broken, the laptop will not receive the signal to boot up.

  1. 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.

  2. 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.

    • 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!

    • Locate the power button in the corner of the keyboard plate cover.

    • Disconnect the ribbon from the small green board by flipping up the small white flap and pulling parallel to the green board's surface.

I broke the middle ribbon! Do you know if that is replaceable? What part number would I order?
