what kinda drugs are the chromebook people on. who thinks this is a reasonable flashing procedure. (it doesn't work with the device i have and i've spent a hour so far figuring out why)

Q4 is a transistor in WLCSP, because you must suffer not only while flashing it (exactly once, you can enter DFU mode via software later on) but -also- while assembling it.
this design is like a crash course in making the least accessible OSHW you can possibly imagine

spent almost two hours figuring out exactly where the galaxy brain scheme went wrong. in the end the workaround was to cut the trace anyway, sigh

this is kind of cute but it would be a lot more cute if not for the preceding frustration
ah well. i went with an OSHW device that had some serious flaws because i knew we could fix them, and we'll just get onto that now

having used the software for 15 minutes, i must say this is an absolutely phenomenal level of jank for something that google has literal total top-down control over

the way the interface for the Chromebook PD sniffer (chromium.org/chromium-os/tw) works is that it busy loops sending the devices console commands over USB serial. which mostly returns ZLPs. this pegs a core even if you have no PD traffic at all

Replying to
power management on AC still matters for two reasons:
- it determines how quickly the laptop charges
- it affects how hot the goddamn thing gets
(in my laptop, the hottest chip without active cooling dissipates to the palmrest, exactly where my palm goes. brilliant move)

Meticulously designed to use a human as a water cooling system. As far as I can tell, that's what ultrabook means.
humans are also capable of total-loss two-phase cooling and i have had a laptop which exercised that feature in myself
