Einleitung

The Asus X551CA CMOS battery provides power to the motherboard while the laptop is turned off so that information such as the date, time, and system settings are not erased.

    • 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.

    jason is right

    correct, swap the green and red

    Jason is correct

    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.

  3. TIVAeYCtcuG2BfKi

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

    • 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?

    wiedzmin -

    Yes and you have to put lotion on

    joemidjette -

    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!

    • Once the screws have been removed, place your fingers on the left corners and push the hard drive towards the right edge of the laptop (relative to the picture).

    • Once it is free, remove the hard drive from its internal cavity.

  9. DLy1jh5O6IZtMStv

    • 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.

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

    • Use the Phillips #0 Screwdriver to unscrew the 3.2 mm Phillips #0 screw which attaches the WiFi card to the motherboard.

  12. JRDblQQARmxL5wsQ

    • Disconnect the Wifi card from the motherboard by gently sliding it towards the right edge of the laptop.

  13. hHG4lYMUTlXTrfSN

    • 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.

    Could i replace It for a wifi ac card? Wich could be compatible?

    This computer uses a Mini PCIe slot card, as you can see in the photo's. You can órder almost any card, from either FENVI brand (Intel) or Artheros (Qualcomm), just make certain you order a card that specifically says it is a HALF HEIGHT Mini PCI-e card. Intel stop producing cards like this after the 7265HMW card but other brands make compatible cards. In the Intel design, any card that ends in 'HMW' is a card that is a mini PCIe card. If you see any other combination of letters then it is not likely to be compatible.

    If you have any questions, ask the vendor if the card is compatible with your computer.

    • 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 -

    Top two screws, next to the display hinge, are slightly larger screws.

    • 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.

What is the correct battery to use? Where can I purchase it?

Mark Thompson -

the battery is a cr2032. Its one of the most common battery sizes available just about anywhere from a grocery store to amazon.

Josh -

does replacing this battery improve battery life?

proa_michael -

Hello, my Asus x550za suddenly shut off and will not boot. No power, no lights. I've verified 19 volts coming through the AC adapter, power jack and power jack port. I noticed that one side of the CMOS battery holder came unsoldered from the motherboard and is hanging. Could this have caused the laptop to suddenly turn off and to not be able to boot?

Thanks.
