In this guide I explain how to diassemble an Asus K53U.

I’ll go though the following major laptop disassembly steps:

ШАГ 1-4: Accessing and removing the memory modules, hard drive, DVD drive and wireless card.
ШАГ 5-11: Disconnecting and removing the keyboard.
ШАГ 12-16: Removing the palmrest assembly. Accessing the CMOS battery.
ШАГ 17-21: Disconnecting and removing the motherboard.
ШАГ 22-24: Accessing and removing the cooling fan and DC power jack harness.

By the way, in the second guide I’ll explain how to remove and replace Asus K53U screen.

OK. Let’s take it apart. Make sure the computer is turned off before you start.



ШАГ 1.

Unlock and remove the battery.

ШАГ 2.

Remove two screws securing the hard drive and memory covers on the bottom.

Under those covers you can get access to the hard drive, wireless card and two memory slots.

In my Asus K53U I found only one memory module installed.

I’ll leave the wireless card and memory module connected to the motherboard.

ШАГ 3.

Slide the hard drive to the left to disconnect it from the motherboard.

Lift up and remove the hard drive.

Asus K53U has a regular 2.5? SATA hard drive installed.

ШАГ 4.

Remove one screw securing the optical DVD drive.

Slide DVD drive to the left and remove it.

ШАГ 5.

Remove two screws securing the keyboard on the bottom.

ШАГ 6.

There are three spring loaded latches securing the keyboard on the top.

Push on the latch with a small screwdriver.

When the latch pushed in, the keyboard will lift up a little bit and the latch will not move back into the locked position.

Unlock all three latches.

ШАГ 7.

Now you should be able to lift up the upper side of the keyboard and turn it upside down on the palmrest.

STEP  8.

The keyboard connector has to be unlocked in order to release the cable.

In the following two steps I show how to unlock the connector and remove the cable.

ШАГ 9.

Carefully lift up the left side of the connector retainer with your fingernail.

The retainer will open up at a 90 degree angle.

ШАГ 10.

Now you can pull the cable from the connector.

ШАГ 11.

Remove the keyboard.

ШАГ 12.

Remove all marked screws from the bottom.

ШАГ 13.

Remove three screws securing the palmrest assembly.

Disconnect the power button board cable (upper arrow) and touchpad cable (lower arrow) from the motherboard.

You’ll have to unlock the touchpad cable connector same way you unlocked the keyboard connector in steps 9-10.

Here’s how to unlock the power board cable connector and remove the cable.

Carefully slide the white cable retainer to the right about 1-2mm. Do not apply to much force! The retainer must remain attached to the connector base.

On the following picture the connector shown in the UNLOCKED position. As you see, the retainer still attached to the connector.

Now you can pull the cable from the connector.

ШАГ 14.

Start separating the palmrest assembly from the bottom cover.

ШАГ 15.

Remove the palmrest assembly.

On the bottom part of the palmrest assembly you can access the power button board and touchpad.

NOTE: the left and right buttons are not part of the touchpad. In Asus K53U both touchpad buttons soldered to the motherboard (you can see them on the next picture).

ШАГ 16.

When the palmrest assembly removed you can access the CMOS battery.

It’s a regular coin battery which can be easily removed and replaced.

 

DISCONNECTING AND REMOVING THE MOTHERBOARD.

In order to remove the motherboard it’s necessary to disconnect the power jack cable and wireless antenna cables first.

ШАГ 17.

Unplug the power jack cable. This connector located on the bottom close to the memory module.

ШАГ 18.

Disconnect both antenna cables from the wireless card.

ШАГ 19.

Remove one screw securing the motherboard.

Disconnect the video cable, speaker cable and USB board cable from the motherboard.

The speaker cable has a regular male-female connector. Unplug the speaker cable from the motherboard.

Unplug the USB board cable from the motherboard.

Lift up the video cable connector by the black belt on the top and disconnect it from the motherboard.

ШАГ 20.

Start removing the motherboard from the bottom cover as it shown on the following picture.

ШАГ 21.

Remove the motherboard.



ШАГ 22.

The cooling fan is mounted on the bottom part of the motherboard.

Yes, it’s necessary to remove the whole motherboard in order to access and replace or clean up the cooling fan.

Disconnect three screws securing the fan to the motherboard.

Unplug the fan cable.

ШАГ 23.

Lift up and remove the cooling fan.

ШАГ 24.

The DC power jack harness mounted in the upper left corner of the base assembly.

After the motherboard removed, the DC jack harness can be easily accessed and removed.

Всё! Ноутбук разобран. Сборка происходит в обратном порядке, если у вас возникнут сложности вы всегда можете обратиться к специалистам.
