In the first part of this guide I will take apart the laptop case and in the second part I explain how to open up the display assembly.
Part 1. How to disassemble laptop case.
Remove one screw securing the memory cover. The screw is hidden under the plastic sticker which can be removed using a needle. Remove the cover.
Asus X555 series laptop has only one removable memory module.
You can install up to 8GB DDR3-12800 SODIMM RAM module into this slot.
When you remove the RAM stick, you can see the memory chips integrated into the motherboard.
Remove all screws from the bottom.
Warning! These screws have different length. Make notes or draw a diagram of where each screw is located. If you install a wrong screw into a wrong hole, you can damage the case.
Using a plastic opener pry the top case palmrest assembly up and separate it from the bottom case.
Lift up the top case to access the cables. You will find the keyboard cable and the touchpad cable connected to the logic board.
Befor you pull the cable out, it’s necessary to unlock the connector.
Lift up the locking tab so it opens up at a 90 degree angle (red arrow).
Now, when the cable is released, you can pull it out.
On the other side of the top case you can access the touchpad. The keyboard is riveted to the top case and cannot be easily removed.
Remove three screws securing the battery.
Lift up and remove the battery. Replacement battery model: C21N1347.
Remove one screw securing the CD/DVD drive. Slide the drive to the right to disconnect it from the motherboard and remove from the case.
Disconnect the cable from the hard drive board.
Remove one screw securing the I/O (USB / Audio Jack / Media Card reader board).
Remove the I/O board with the cable.
Remove two screws securing the hard drive caddy.
Slide the hard drive assembly to the right to disconnect it from the board and remove it from the case.
Installing a 2.5″ SATA solid state drive instead of this regular hard drive will improve laptop performance significantly.
Remove one screw securing the hard drive board. Disconnect the speaker cable.
Lift up the hard drive board to disconnect it from the motherboard.
Unplug the wireless card antenna cable.
Remove five screws securing the motherboard. Disconnect the video cable.
The connection is secured by clear sticky tape. Peel off the tape and unplug the video cable from the motherboard.
Remove the motherboard from the bottom case.
On the other side of the board you can access the cooling module (heatsink and fan) and the wireless card.
The DC power jack is soldered to the motherboard.
Part 2. Display assembly and screen removal.
In Asus X555 series laptops the display assembly cannot be taken apart until it’s removed from the bottom case.
You can use this part of the disassembly guide for accessing and replacing the LCD screen, display hinges, video cable and webcam.
Remove all screws securing the display hinges and separated it from the bottom case.
Slide the hinge cover to the shown direction.
It can be done only when the display is out of the case.
Remove the hinge cover.
The screen bezel has two screws on the bottom. They are hidden under plastic covers. Remove both screws.
Now you start separating the screen bezel from the back cover. A plastic case opener tool will be helpful.
Remove the bezel.
Remove four screws securing the LCD screen to the display back cover.
Remove the screen from the cover and place it the front side down on the desk. Now you can access the video cable.
Peel off clear tape securing the connection and unplug the video cable from the screen.
You can search for a replacement screen using the model number which is printed on the back. In my case the screen model is N156BGE-E42.
