or soda.. for u.s. people. anyway i had a liquid spill on keyboard near power button and hinge. soaked up what i could, dryed er up, used electronic spray cleaner and she worked ok, on and off with display issues going from double horizontal imaging fading in and out to then now just vertical lines on start up. took cover off and looked for residue and cleaned few spots. still the same. ?should i take out keyboard and soak and drain it with isoprpyl 99? ?do i need to take off that black plastic cover beneath keyboard unit?
