My MBP retina 13" is suddenly dying when I remove the adaptor

Hi guys,

I had an accident and I spelled yogurt on my brand new Macbook pro retina 13" !! After that it suddenly stopped working and I tried to dry it and it worked fine the next day on the battery until it got drained. Then when I tried to charge it it didnt respond so I opened the Macbook and cleaned what ever I can see and later on it started charging and the macbook worked fine again .. Now the problem is that when ever I remove the adaptor the macbook suddenly dies even the battery is fully charged and its status in the system information is normal ..

Can u please help with my problem as my macbook is still completely new and im messing with already !!

Thank you ..
