In this guide I show how to disassemble Asus Q553 Q553U Q553UB Notebook PC.
In the first part of the guide I will tear apart the laptop case and in the second part I will take apart the display assembly. As you noticed, in my laptop the screen digitizer glass is cracked and it stopped working. We’ll take a look if it’s easy to replace the digitizer or not.
Taking apart the laptop case.
Remove all screws from the bottom case.
Separate the bottom case from the top case and remove it.
Remove four screws attaching the battery to the top case.
The speaker cable attached to the right side of the battery. While removing the battery you will have to un-route the cable from the guided path.
Lift up the battery connector and unplug it from the motherboard.
Remove four screws securing the hard drive bracket. Slide the hard drive assembly to the left to disconnect it from the motherboard. Remove the hard drive.
Remove one screw securing the optical CD DVD drive. Slide the optical drive to the left and remove it from the laptop case.
Asus Q553 Q553U Q553UB motherboard has only one removable memory module. The memory module located under the metal cover which can be easily removed.
You can leave the memory module connected to the board unless you are replacing it with another one.
The second memory module integrated into the logic board and I will show where it’s located later, after I remove the motherboard from the case.
Remove there screws from the cooling fan and four screws from the heatsink.
Disconnect the fan cable from the motherboard.
Lift up and remove the cooling module assembly.
The cooling fan is permanently attached to the heatsink.
Remove one screw from the USB SD card reader board.
Disconnect the I/O cable from the board.
Here’s how to disconnect the cable.
- Unlock the connector by lifting up the locking tab (red arrow).
- Pull the cable out of the connector (yellow arrow).
Remove the USB SD card reader board.
Remove the hard drive board with the cable.
You will have to lift up the board in order to unplug it from the connector on the motherboard.
The CMOS battery is hidden right under the hard drive board.
Disconnect both antenna cables from the WLAN card. It’s a dual band wireless-AC card.
When you remove one screw securing the WLAN card, it will pop up at a 30 degree angle.
Pull the WLAN card out of the slot.
Remove one screw from the power button and volume control board.
Disconnect the cable.
Remove the power button and volume control board.
In order to remove the motherboard, it’s necessary to open up the left hinge.
Remove four screws from the left hinge.
Lift up the left side of the hinge so it opens up at a 60 degree angle.
Remove three motherboard screws. Two of them located on the LAN port cover.
Disconnect the following cables:
- Keyboard data cable (red rectangular).
- Touchpad cable (orange square).
- Speaker cable (green square).
- Keyboard backlight cable (yellow square). Attention!!! It’s easy to overlook this cable because the connector is small and located in the middle of the motherboard.
- Display video cable (purple rectangular).
Both wireless antenna cables are taped to the motherboard in the fan area. It’s necessary to remove the tape and separate antennas from the motherboard.
The keyboard connector unlocked the same way as other flat cable connectors.
In order to disconnect the display cable simply lift up the connector using the black belt on the top.
Separate the motherboard from the top case and remove it.
Here’s the other side of the Asus Q553 Q553U Q553UB motherbaord.
The integrated RAM located under the silver shield. It’s permanently attached to the board and cannot be removed or replaced.
The touchpad attached to the top case by three screws. I’m not removing the touchpad in this guide but it shouldn’t be difficult.
The keyboard is permanently riveted to the top case and cannot be easily removed. If your keyboard failed, I would suggest replacing the entire top case.
Removing the display and taking it apart.
Remove four screws from the right hinge.
Open up the right hinge the same way as the left hinge earlier in the step 17.
With both hinges opened up, you can easily separate the display panel from the top case.
Now let’s take apart the display panel.
There are two screws located in the lower left and right corner of the display assembly. They are hidden under the plastic covers.
Remove both covers and both scews.
Insert a think plastic case opener between the LCD screen/digitizer assembly and display back cover.
Pry up and unsnap the LCD screen/digitizer assembly from the cover.
Move along the side of the display separating one part from the other.
Continue separating them on the top, sides and bottom of the display assembly.
Remove the LCD screen/digitizer assembly from the back cover.
Here’s the display back cover where you can access and remove both hinges if necessary.
Here’s the LCD screen/digitizer assembly.
The LCD screen is glued to the back side of the front bezel frame and can be removed relatively easy.
The digitizer, on the other hand, is glued to the front side of the bezel and removing it can be a real pain, very similar to replacing cracked glass on MacBook Pro.
I searched on eBay and found a few digitizers available but no-one was selling it with the bezel.
After some consideration, I decided to replace the entire LCD/digitizer assembly as it shown on the following picture.
