I think it important to mention that you should not reproduce this disassembly as it may damage your unit and will void your warranty.
[TL : DR] Here are some key points if you don’t want to read the entire post:
- Replacing the screen isn’t all ‘that’ difficult and...
- replacing most components isn’t particularly difficult either, with the notable exception of...
- ... the keyboard, which is rather hard to remove from the chassis.
The first thing I took apart was the screen (stupid of me - I should have removed it from the body first...oh well). The screen is held in place by plastic hooks which run all around the bezel of the screen. There are also four metal pegs holding it in place which located under the squishy pads / standoffs on each corner of the bezel. The plastic hooks release easily when a pry-tool is inserted but the metal pegs require considerably more force to come undone. If you do it super gently few marks will remain on the plastic. I can confirm that the construction is the same is true on the 11” production model.
Inside, the LCD is held in place by four screws - 2 at the bottom and 2 on top. Other than that we also find the webcam, which is connected to the same cable as the LCD panel, and two magnets for the hall switch. That’s pretty much all there is - not that you would expect anything else.  It appears that on the 11” production unit the wifi antenna is also routed inside the the screen, so one should be careful not to tear it by accident when separating the bezel from the back of the lid.
To remove the screen from the body of the laptop - which I should have done in the first place - you will need to take of the bottom cover. The bottom cover is only held in place by 10 philips screws so it comes off very easily; lift it from the front and gently pull up.
To separate the screen from the body, all that is needed is to undo the hinges on both sides and the screen connector located on the main board. The hinges are held in place with philips screws and come right out. After removing the screws, the hinges need to be carefully bent back to a 90* angle (as if the Pinebook would be normally used) and to separate the screen all one needs to do is push it away (back) from the body. If the hinges are ‘flat’ it is very difficult to separate remove the screen/ lid.
Onto further disassembly. The first thing that needs to go is the battery. The battery connector on the main board pops up and out when gently lifted from the bottom. The battery itself is held in place by a couple of screws - there is no adhesive, so removing it is very easy.
Next up the daughterboard on the left side of the body (when viewed upside-down from atop). It’s held in place by two large screws and some adhesive tape. There is only one connector for a ffc cable held down by a hinge that needs to be lifted. You will need to gently pull up and away from the plastic case to remove it, because the USB socket sits inside the plastic.
Onto the main board. Here you will have to separate the 5 more cables (from left to right as viewed from atop): the microphone, cable running under the battery to the daughterboard, the microphone, the large flex cable is for the keyboard, trackpad and lastly speakers (LCD + camera and battery have already been removed). For the daughterboard, keyboard and trackpad cables, simply lift up the hinge and slide the cable out. For the microphone and speaker cables, wiggle the connectors out from their sockets (don’t pull by the cables - they look fragile). The mainboard is held in place by 4 more of those same screws as found on the daughterboard. To remove it from the chassis, lift it up on the far end of the board and pull away from the plastic where the Micro SD, USB and headphone sockets sit.
With most of the stuff out already the harder part begins, namely trackpad and keyboard removal. First things first - unclip the cable that connects the trackpad to the mainboard by lifting the hinge and sliding out the cable. I will return to the trackpad in a bit…
Onto the keyboard. The keyboard is located under the metal cover which held in place by a couple of philips screws and plastic ‘tabs’. After removing the screws comes the hardest part of the disassembly as you will have to remove, one by one, all the plastic tabs protruding through the metal. I chose to cut of the tips of the plastic using a precision knife and it took me a long time. It’s clear that this part of the assembly was never meant to be removed by the end user (do note, I have since reassembled the keyboard and removing the plastic tabs has significantly affected the rigidity not only of the keyboard but also entire bottom section). Once all tabs are cut, you can lift it up and push it towards the back and the keyboard will slide right out as it is not held in place by glue or adhesive tape. About the keyboard; the keycaps come right off and snap back with ease. The keys have a butterfly-like assembly under which there is a dome.
Back to the trackpad. To remove the trackpad I first lifted the a bottom lip using a pry-tool. It’s held in place with a lot of adhesive and quite hard to remove. Once the lip was out I pushed firmly in the place that the lip was protecting, towards the outside of the case. The trackpad is held in place with a lot of adhesive tape, so I ended up using a bit of hot air to make it come out.
Lastly, there are the speakers. They are held down with adhesive but can easily be popped out by placing a pry tool in the cable-routing hole and gently pushing up.
And so the teardown is complete. I also managed to reassemble everything without relative ease. I don't know if anything was broken in the process (other than the sturdiness of the keyboard) since the unit was already broken in the first place. If I were iFixit I'd probably rate this device a solid 10/10 because the unit is, for the most part, put together using regular screws and clamps which make things easy to remove and refit. Also, very little adhesive and glue was used on this particular pinebook which is a big plus for repairability.
