bought as non-working on ebay for ~100 cad. turned out all internal flex cables were torn (???), the keyboard had several bad keys, plus an unrelated short in the touchpad caused it to intermittently think the power button was held down 😅

...at least the main board and screen were alright, and i stole cables and a keyboard (~90 screws, yay) from a second machine. the touchpad issue confused me for a while but resolved in the end just by cleaning corrosion!
