    Check SMC_LID is high. Also do not comment on a topic, use the reply option.

        Is SMC_ONOFF going low when you press the power button? Was this liquid?

                    When you do an SMC reset (left shift+alt+ctrl+pwrbtn) does the machine immediately turn off and magsafe turn green?
