Spilled tea on my laptop, before I switch off it turned off by its own, I tried to take it apart but could not do that fully. dried it for a day and switch on, fan and green light go on the screen doesnot for 10 sec, and turn off by its own again. next day took all apart and noticed liquid dried marks only on the corner of the motherboard. I cleaned with isoprobyl 91% and left for a day to dry, but same thing happens. for about one week now every time I switch on same thing happen, any advice?!
