Introduction

This guide will cover the replacement of the motherboard in the MSI MS-1782 laptop. This part of the laptop is responsible for connecting all the processes of the MSI MS-1782. Check out the troubleshooting page if your laptop is having charging related issues.

When working on the laptop make sure to disconnect the battery first. Also be sure to disconnect all the ribbon cables before removing the motherboard. There are separate daughterboards for various I/O and those have to be disconnected for removal as well. Lastly the display cable is the most fragile so be extra careful with that one.

Tools

Step 1

Remove five 6.6 mm screws from the edges of the bottom cover using a JIS #1 screwdriver.
Remove one 5.6 mm screw from the center of the bottom cover using a JIS #1 screwdriver.

Step 2

Use an iFixit opening pick to unclip the bottom cover.
It is ok to run the picks along the edges since there is nothing connected to the bottom cover. It is easier to start from the sides and then work your way forward.
After unclipping the bottom case, pull from the back of the laptop upwards using the lip of the bottom case as a handle.

Step 3

Use the flat end of a spudger to detach the two antenna cables from the Wi-Fi card.

Step 4

Remove the 5 mm screw holding the Wi-Fi card in place with a JIS #1 screwdriver.

Step 5

Remove the Wi-Fi card at its angle.

Step 6

Loosen the captive screw on the left side of the left fan using a JIS #2 screwdriver.
Remove the 5.1 mm screw on the right side of the left fan using a JIS #2 screwdriver.

Step 7

Gently detach the fan connector.
Remove the fan by lifting it out of its housing.
Be sure to handle the wire delicately; if not it will break.

Step 8

Loosen the captive screw on the top of the right fan using a JIS #2 screwdriver.
Remove the 3.6 mm screw on the bottom of the right fan using a JIS #2 screwdriver.

Step 9

Gently detach the fan connector.
Remove the fan by lifting it out of its housing.
Be sure to handle the wire delicately; if not it will break.

Step 10

Loosen the eight captive screws holding the heat sink in place using a JIS #2 screwdriver.
Be sure to follow the numbers that are next to the screws on the heatsink. This evenly removes pressure on the components when removing the heatsink.

Step 11

Gently lift the heat sink and then pull forwards towards you.

Step 12

Remove the four 5.5 mm screws holding the battery frame in place using a JIS #1 screwdriver.
Gently disconnect the cable connecting the M.2 caddy to the motherboard.

Step 13

Remove the 3.6 mm screw holding the M.2 caddy in place using a JIS #1 screwdriver.

Step 14

Gently disconnect the two blue ribbons.

Step 15

Remove the 5.1 mm screw holding in the disk reader using a JIS #1 screwdriver.
Use an iFixit opening tool to push the back of the disk reader to push it out of the laptop's chassis.

Step 16

Gently pull the disc reader out of the laptop.
Lift the plastic cover and disconnect the cable connected next to the speaker.

Step 17

Remove the five 5 mm screws holding the frame in place using a JIS #1 screwdriver.

Step 18

Pry up on the battery frame with an opening tool and unclip from the main chassis, working your way around the laptop.
To remove the battery, pry up on it to unstick the adhesive.
A little Isopropyl alcohol under the battery can help unstick it from the frame.

Step 19

Remove the five 5.6 mm screws holding the motherboard in place using a JIS #1 screwdriver.
Disconnect the display, keyboard, trackpad, and USB daughterboard ribbon connectors from the motherboard.
Before disconnecting the ribbon cables, lift the black tab before pulling the blue tabs on the cables.
Do not pull the cables out of the connector before lifting the black tab. Damage can occur to connector if not done so.

Step 20

Remove the two screws holding the sound daughterboard in place.
Disconnect the cable attached to the board.
The daughterboard is still connected to the laptop so just place it to the right.

Step 21

Lift the daughterboard and turn it to the back.
Lift the clear tape and pull the connector straight back to disconnect the daughterboard.

Step 22

Disconnect the USB daughterboard from the motherboard.
The orange ribbon cable is attached to the underside of the motherboard so it will stay attached when removing the motherboard.
