I spilled something sticky on the bottom left side on the trackpad on my ASUS UX430U Notebook. The touch still works fine but it wont click in that area. Is this something i could clean by myself or should i contact a professional? And if I can clean it myself is there some guides to open it and not destroy anything?
Some 99%+ Isopropyl alcohol and a cuetip may be able to clean it up without opening it up, but it may be underneath the edge, at which point you may need to open it up to get it cleaned. Look around for a repair manual for your computer, or videos if you want to try opening it up. Without knowing your skills, I cannot say if you can/should do it yourself.
