  1. Ports on the side:
    • Ports on the side:

      • Headphone Jack

      • SD/SDHC/SDXC card slot

    • Ports on the Back:

      • USB 3.0

      • USB 2.0

      • HDMI

      • 40W DC in charging port

  2. Time to grab the tools and open the case.  Nothing fancy needed here, just a simple phillips screwdriver, a knife and a spudger.
    • Time to grab the tools and open the case. Nothing fancy needed here, just a simple phillips screwdriver, a knife and a spudger.

    • Remove the 5 visible Phillips #0 screws.

    • Remove the 4 hidden screws under the rubber feet (one under each rubber foot). If you only partially pry up each foot enough to get to the screws, you can reuse the feet without having to re-glue them.

    • Disassemble this back piece, since it will ease a lot the prying of the bottom part

    • By doing this, you will avoid ending with couple of "clicks" broken, specially during the tear up

    • If you have the 3G model, be sure to remove the SIM card from this slot before going any further.

    • Time for some spudger love

    • Start with all the clicks in the back part, the rest will come out almost without force

    • With the under case set aside, we now have an open case and a preview of the components to come

    • Remove the 6 battery screws then carefully pry the battery connector straight up to remove it.

    • Battery removed, it's now time to remove the screen and pull the main board

    • Disconnect the 2 antennae lines from the main board

    • Disconnect the screen cable

    • Remove the 5 screws holding the main board

    • Probably a good idea to disconnect the remaining 4 cables as well

      • Keyboard and trackpad ribbon cables

      • Audio cable

      • CMOS Battery Cable

    • We now have a main board with the heatsink attached

    • Remove the 3 screws and tape

    • Done!

    • Top of the main board

      • Samsung Exynos 5250 AEON main proc

      • SanDisk SDIN7DU2-16G NAND Flash

      • 4 x ELPIDA J2108EDBG-GN-F (4 more on the rear)

      • MAX 77686 EWE 1237

      • TPS65090 TI 291

      • "Servo" dev/debug interface.

      • Connector for 3G daughterboard.

    • The Embedded Controller, according to Google's documentation is STM32F100R8, although it is marked as "32F100B6"

    • Trusted Platform Module, Infineon SLB9635

    • Not much more on the rear but the rest of RAM

    • Not teardown relevant per se, but these are beautiful traces

    • By removing this flexible metal ring sticker, you disable the Write Protect of the bootloader's flash.

    • This risks making the device unbootable, therefore bricking the device beyond repair. Of course, there are basically no other modifications that can be made to the interior of a Samsung Chromeboook 3 anyways.

When re-assembling the chromebook, I have noticed that the factory assembly is done in a different order (and thus the disassembly should be done in a different order as well). Let me explain: there is a small plastic piece, long and low, in the back part of the laptop (where the connectors are). For me, it is 100% clear that this is the latest part in the assembly process at the factory, because of the position of the plastic clicks.

So for disassembly it should be the first part to be removed. It helps a lot removing this part first, in order to avoid any click to be broken.

But prior to modifying the teardown I would like to know if you agree in that this is the correct process (or your opinion).

(BTW I know that Google has posted some disassembly instructions on their chromiumos page, but for me those instructions are not correct as well. Note that the manufacturer is Samsung and not Google, and that's why I'm afraid the instructions are not precise).

Both of my Samsung Chromebooks are on loan to friends, so I will have a hard time verifying your question for a couple of weeks. Please update the teardown as you see fit.

I can always come back and update the photos (or take new ones) if you like, but it will be delayed.

If the part you are referring to covering the screen to body hinge? That part actually doesn't need to be removed at all if you are just digging for internals. The screen can stay connected.

Josh, I've just added the instructions along with some photos. Feel free to delete or modify the steps inserted if you consider so, as the teardown is your property.

All the best!

Awesome! It' not my teardown, it's for the community so any addition is a good one :)


Josh Thomas -

Very nice guide. Thanks for creating! Would like to see it as a PDF since I couldn't get it to print out very well.
