"[...]especially knowing it can run on batteries for 10 hours (allegedly), without having a UPS."

In my experience of trying the same, this is a swollen Li-Ion battery waiting to happen.

Given that the monitor is a big part of power draw, it will probably last longer than that with the lid closed. Of course if you lose power, you probably lose the wifi router it's connected to anyway.

I bought a few cheapo UPS units one time. They're only 2-prong (no ground) and the capacity is low. But they were like $20 each with "refurbished" batteries from the vendor.

All of my routers are 2-prong so I have one unit for every router/switch/AP in my house. Actually really helpful and if I was running a Chromebook for a server like this, I could keep my services accessible remotely even if a short power outage happened!

There are kernel modules to float charge at 80% (or any %) and not stress the battery.

Is there a generic way to do it now, or is it still hardware-specific? (Last time I looked I was on a thinkpad and using tp_smapi)

So unplug it ever few days for an hour?

Or use a timer, 0.5 h every night?

I don't know if it works on chromebook hardware, but some laptops let you manually control whether/when the battery is charging, ex. https://unix.stackexchange.com/questions/48534/how-to-adjust...

Yep, it is fire hazard.

Everything with a lithium ion battery is a potential fire hazard.
