This cola soaked laptop does have issues because of the cola which is sticky but the cola can corrode the wiring so the best thing you can do is first disconnect the power and battery. Get some Isopropyl Alcohol of 90% or higher and clean out the Cola mess using Cotton Swabs Swab Q-tips 6" Extra Long Wood Wooden Handle Cleaning Applicators. Make sure to use an antistatic mat with wrist strap so you do not do anymore damage. Do you best on cleaning up any mess that you can discover when taking it apart. Be sure to have so thermal paste and keep record of taking it apart so you can put it back together. If you have to clean the Mother board then be sure to let the Isopropyl Alcohol dry before putting it back together. Also if you have to clean the CPU chip or any chip with thermal paste be sure to replace the thermal paste. The cleaning task could be rather extensive due to the cola. And it still probably will not work even after the work. Trust me I know. Had the same happen to my Gateway laptop, even after cleaning it never worked as before had to toss it. Kept the HDD though that still worked.
