Introduction

If you're having trouble with the Motherboard of your Asus laptop (model Q504UA-BHI5T13) this is the guide for you. The motherboard is used for distributing power throughout the computer, maintaining the memory and connecting to other CPU's. A faulty motherboard could cause problems to any of these computer functions. Before disassembling the computer ensure that you have the correct replacement motherboard (this can be found by consulting the laptop’s user manual or contacting the manufacturer directly). When finished with the replacement instructions take the previous motherboard to an e-recycling facility for the safest disposal method.

Be sure that there is no external power cord connected and that the laptop is fully powered off and shut down.

Step 4

Use the Phillips #0 screwdriver to remove the two 4mm screws that are under the rubber pads.

Step 5

Insert any of the plastic opening tools into the seam to separate the back cover (it is recommended to start at the corner of the hinges). If you did it right, then the cover should pop off.
Be careful as you may damage the tabs.

Another good place to start is at the USB port near the SD card slott. Work toward the hinge first, then back down the short side. There are 5 strong tabs on each short side, and several weaker tabs on the front and between the hinges. The tabs are attached to the bottom. Once one short side is nearly free and the front seam is not totally closed, then try pushing the bottom toward the free short side (at most 1/2 mm) which can make the other tabs easier to “pop”.

Once the back cover is removed, have the laptop facing upside down with the hinges facing toward you.

Step 12

Using the same screwdriver, remove the four 4mm black screws around the copper lining
First remove the screw in the red circle.
Then remove the screw in the orange circle.
Next remove the screw in the yellow circle.
Finally, remove the screw in the green circle.
For this step, it helps to remove the screws in this order to prevent damage to the heat sink.

Step 13

Use a pair of tweezers to pull and disconnect the cable located to the right of the heat sink fan.
Take caution when removing the cable. Damaging the cable will stop the part from working.

Notice the space and socket for M.2 SSD (42mm or 80mm) between the HDD and the battery! (Screw needed.)

Step 17

Use the Phillips #0 screwdriver to remove the eight 4mm screws around the hard drive casing (located next to the Right [R] speaker).
Start off with the four black outer screws so that the casing can be released from the laptop unit.
The next sequence of screws to remove are the four silver screws.

You should disconnect the data cable from the mb and pull the whole cage & drive assembly before you take out the silver screws or detach the cable from the drive to make it easier to insert or remove the drive.
