    Hello James. Thank you for your work, it is really well illustrated, simple and easy to understand. I would like to ask you: My computer (exactly this model: Lenovo Thinkpad S1 Yoga) has sadly received a cup of tea (computer on). I instantly turned it back to avoid the water to go inside and turn it off. I had it drying during the first day and in that period the computer started normally by itself twice, I turned it off to be sure that is dry before using it again. After a day when I tried to start it again it seemed to not to have energy and the charger did not work. So I took off the battery (it was wet). Now the battery is dry and accepting charge. The computer now turns on the power light (the only red light in the right side) but nothing else happens. The starting processes are not running at all. Do you have any idea, any suggestion about what I could try to do? Thank you very much. Best regards, Emiliano.

      remove all parts including the keyboard. make sure u remove all the connections. then use some kind of alcohol solution on a qtip and apply to ALL (every single connection) connections on the board, the connectors, like everything. once u are done, let ur parts dry out for a day or so. put everything back togethor. then start up ur pc. this time, whatever parts fail to start up, remove them and re-apply the alcohol and let them dry. put everything back and start ur pc. if anything fails to start up, it means u have to replace those parts. also look on all the boards and see if the curcuitry has rusted or if it looks weird. water/ other drinks can damage the curcuitry on a board (pcb) on the ram chips, motherboard etc. make sure all the connections, contacts and curcuits on every board is shiny clean (use alcohol on qtip to do so)
