Repurpose broken laptop (broken mobo)

Heya guys,

I had a Google Chromebook Pixel LS (2015) break on me in early 2020.. It just lost power at one point and would not power back on again (took it apart, disconnected the battery etc)... I'm fairly certain something has gone wrong with the motherboard that would need a level of electronic hardware debugging I just don't have (and access to schematics that I don't think anyone outside of Google has).

Anyway, the machined metal chassis is pristene, the screen is great - and touch screen - the keyboard is fine, the LED lights on the back of the device were cool, it has "workable" speakers and a battery bank that would probably operate with 75%+ capacity (or I could get another bank).

Repurposing to use this again would be pretty cool instead of throwing all these great parts away - it's fairly hard to try get replacement mobo's, and it would be better IMO just to get newer products and maybe even a "build it myself" aproach.
But I cannot find anything more useful then a dodgy "turn your old laptop screen into an external monitor" type guide where the driver cards are large and accepting HDMI input, and they expect the monitor to be puler from the case because it's a plastic dell / lenovo laptop screen being repurposed.

Does anyone have any advice or links to places to help me stick parts together to get stuff working?
I assume I would want some sort of GPIO interface for the LED lights on the back, a USB-C battery charging + power board, something to accept all the ribbon cables that are in there.
I am happy with various powertools, soldering, modifying, testing continuity etc...

Thanks for any help that can be given.

So, you want to build your own MoBo? 🤔

If so, Raspberry Pi is great starting point. However, without knowing the pinout of all the (ribbon) cables, it would be nigh impossible to build custom MoBo for it.
Still, Raspberry Pi community may have the required info/data.

it's fairly hard to try get replacement mobo's

While replacement MoBo itself would be hard to get, how about donor device? Those include MoBo and if lucky, working MoBo as well.
