My roommate spilled a coffee on my keyboard.i tried to dried it as fast as i could and first i didn't see any problems but now when i tried to type 5 i saw that is not working...5,t,g and b are working only when i hold the key next to them...some times even when i am holding and trying to press the key it makes for example when i press "t" it writes "qwert"....also the mute button is not working too...does anybody know what can i do? i want to bring it to an official mac store to see if they can fix it or change it but in Dubai there is no official store... i would appreciate any help
