I recently, 5 days ago now, spilled water all over my keyboard on my Macbook air and now it won’t turn on. When I connect my charger, it lights up green but I am pretty the keyboard doesn’t work because i’ve tried holding the power button, resetting the SMC by pressing the keys and it won’t respond to anything when I use the keyboard. Does the charger lighting up mean that there’s still hope? Would an external keyboard be able to connect even if the computer is shut down? Thank you
