Just sat down with a fresh cup and knocked it into my keyboard. Turned it off and started pulling keycaps off, then soaked it up best I could to no avail.
Wouldn’t turn back on after so I dug out every screw, pulled the back off, soaked up as much coffee as I could on the pcb, and ran some isopropyl alcohol under the other side of the PCB where I couldn’t reach.
To my surprise this was enough to get it to turn back on. Keys were registering their neighbors too so I had to scrub it with a toothbrush, but afterwards it’s fully functional and saved me $250 for a replacement
If you ever get electronics wet, do as you did and then put it in the oven to dry. 50-60°C should be enough for about an hour. It will dry off any moisture that could cause electrical shorts.
Never tried one in the oven before. If I start having issues again I’ll run some more isopropyl alcohol through it and cook it medium rare
