Some of my contact solution reacted unexpectedly overnight on a little bookshelf which is in place over where my macbook is stored. A little bit of this solution dripped onto the keyboard, and now a few buttons do not work (delete and a few function buttons). It is still under warranty, because i bought it in November. My question is would it work to tell them that the buttons just stopped working, since there was very little liquid and it would not easily be detectable? If they say it had to be an accident how much would they charge me to replace the key board? or am i better of just buying a replacement keyboard and doing it myself?
