My idiot of a friend tried to fix my non-responsive power button by sticking it in water. Although that worked to fix the power button, he unfortunately damaged the touchscreen. All physical buttons work, and the screen shows a display, but the it doesn't respond to touch. I found out hours later after leaving it on that I could VNC into it to activate SBSettings and shut the damn thing off. Afterwards, I stuck it in a bag of rice and it's been sitting in there for a while now. It has been off and in that bag since the incident last night. How long should I leave it there before attempting to even turn it on? It's a valuable tool for my schoolwork and I'll be needing it quite soon. Thanks.
