Schritt 1

Remove ten Phillips #0 screws that secure the plastic bottom cover to the chassis.
Six 9.6 mm screws
Four 4.6 mm screws
Throughout this guide, keep careful track of your screws so that each one goes back where it came from during reassembly. Installing a screw in the wrong place can cause permanent damage.

Schritt 2

Use a plastic pry tool to get in-between the bottom cover and the lower case assembly.
Be careful not separate the cover too violently or you will risk breaking the plastic clips that are on the bottom cover.

Schritt 3

Push metal bracket away from battery connector.
Use a spudger to push the battery connection straight up.
If you pry too hard, or attempt to disconnect the battery with the metal bracket still in place, you risk pulling the connector off of the motherboard.
Make sure the computer is powered off before removing the battery.

If you pull the without moving that metal bracket, you could damage the connections on the motherboard and likely rip a few solder pads. It almost happened to me when creating this guide.

Schritt 4

Remove the Phillips #0 screws that secure the battery to the lower case assembly
Three 4.7 mm screws.

Schritt 5

Tilt battery up from the side closest to the motherboard
Pull the battery out of the chassis away from the two plastic retainers near the front of the laptop.

Schritt 6

Disconnect the Wifi/Bluetooth RF cables from the wireless card.
Pull the RF cables by the metal connector, not by the rubber shielding. This avoids damaging the connector and the cable.

Schritt 7

Pull straight up to disconnect the SATA combo cable from the motherboard.

Two 2.3 mm screws
One 5.6 mm screw

Remove the SATA combo connector

Schritt 10

De-route the SATA and RF cables from the side of the drive bay.

Schritt 12

Pull straight up to disconnect the display cable

Schritt 13

Use a Spudger to push the left speaker cable out the connector.
Do not pull up on this connector. Only pull directly away from the connector.

Schritt 14

Use a spudger to flip up the retaining flap on the trackpad ribbon cable ZIP socket.
Be sure you are prying up on the hinged retaining flap, not the socket itself.
Use tweezers to pull the ribbon cable straight out of the ZIF socket.

Schritt 15

Use the tip of a spudger to flip cup the retaining flap on the keyboard ribbon cable ZIF socket.
Be sure you are prying up on the hinged retaining flap, not the socket itself.
Use tweezers to remove the ribbon cable from the socket.

Schritt 16

Use a spudger to flip up the retaining flap on the ribbon cable ZIP socket.
Be sure you are prying up on the hinged retaining flap, not the socket itself.
Use tweezers pull the ribbon cable out of the ZIF socket.

Can you identify what this connector runs to? I am looking for the connector for the backlight.

Three 5.6 mm screws
Take a plastic pry tool and open the hinge about 75º-85º
You may have to open the laptop over the edge of a table and open the display in order to open the hinge.

Schritt 22

Pull up on the corner of the motherboard and remove from the laptop.
Be sure to clear all of the plastic standoffs that go through the motherboard.

Where is the CMOS battery located? For the life of me I can’t find it.

Tom Higgins - 24/04/20

Ne meither and Asus didn’t know, either. IDK, my laptop wouldn’t hold BIOS settings or Time/Date. Asus told me it was a coin style CMOS battery on the back side of the motherboard. Called them back to report not finding it and then they refused to help because they accused me of intent to modify the unit, which they do not support. They suggested I send it to a service center on the east coast (I’m on the left coast) with an open limit on repair. All this for a laptop which has been out of warranty for 3 years. Eventually one tech suggested it might be built into the main battery but couldn’t say for sure.

Next time I will buy a Dell, Acer, HP or some other brand.

This laptop mother board does not have the usual CMOS/RTC coin cell battery. Apparently the settings (BIOS/UEFI) are maintained by the laptop battery itself. When I disconnected the laptop battery, the date/time reverts to the original factory date/time. HOWEVER .. there is a cable that contains the LCD connector, the SATA HDD connector based on that some indicate it is a “CMOS cable” which in all the years I’ve been working on computers, have never heard of. That is the same with all MacBook Pro laptops - no CMOS battery — it uses the laptop battery and NOT a CMOS coin cell battery.
