a few months ago i knocked a drink into my laptop. i powered it off as soon as possible following the accident, but there was some lasting damage, in that it doesn't charge anymore or operate without being plugged in. the battery is still detected, and is slowly discharging over time- it's currently reporting 54% available (plugged in)- but as long as it's undisturbed it works just fine. the weird thing is that if it's unplugged for any length of time it won't power on again, at least until i plug a fast charger into the usb c port. i only need to do this for a second or two, which makes me think there's a bad capacitor somewhere? i've been hunting online for schematics for the surface laptop 3 with no luck, any suggestions of where to start would be greatly appreciated.
