3.) In step 4, I was also confused about how to actually pull out the WiFi card. It’s completely impossible to grasp it with fingers—there just isn’t enough room. I don’t understand the part in the guide about slightly lifting it either. Anyway, the solution is to simply pull on the kapton tape (after the screw is removed, of course) rather than trying to grab the card itself. That piece of tape makes it so easy!

4.) Also, reconnecting those “tiny wires” on the WiFi card is actually pretty simple: they just snap into the connector.

5.) I mention 4.) because for me it was impossible to thread the WiFi card through the hole by the GPU fans, as instructed in step 6. Maybe the layout of the wiring varies, but on my laptop, the wires for one of the GPU fan was blocking me from sliding the WiFi card through, and then those “tiny wires” came off the card as I was trying to do it. I say don’t bother and just disconnect them. I found out later that it was easy to reconnect.

2.) One of the ZIF connectors is oriented opposite to the others. That stumped me for a while. Most of them have the tab that you need to flip on the same side as where the cable is inserted, but one of them had the tab on the opposite side.

However, I have a few extra comments or details for anyone else doing this.

1.) I think it’s better to leave the battery connector until you flip the motherboard. On my system it was actually impossible to pull it out without at least lifting the motherboard. There’s some extra rubber pad on my laptop that is glued onto the laptop’s base and it blocks the battery connector from being pulled out. This piece is completely missing in the photo in this guide so there’s some variation between my system and the one used here. Even after lifting the motherboard so the piece was not in the way, I felt uncomfortable tugging on the electric cords rather than the plastic, because that connector is *very* tight, and it was impossible to grasp the plastic of the connector. Only after flipping the motherboard over, was I able to get a grip on the white plastic of the connector and managed to pull it out.

This was amazingly helpful—thank you!

Could someone please explain what the heck those smaller components below the GPU chip are, that are visible in Step 8 and are outlined by 2 rectangles, and why do they also need cooling from thermal paste and heat sink?
