I accidentally spilled water on my pixelbook. Several keys stopped working and the computer would repeatedly reset itself while the usb cable was plugged in. Also it made a hissing noise when the usb cable was plugged in, regardless of which side. First I put it on a rack in my clothes dryer at the lowest setting for 30 minutes at a time. After a few cycles, I recovered use of some keys but others were not working and the usb hissing continued. Encouraged by my success with the dryer, I opened the back of the pixelbook (as if replacing the battery), disconnected the battery, and let it dry out for two days. Now all the keys are working again and the battery charges when the usb cable is plugged in.
