Void sticker triggered?

[iamedelmann]

hey I have a touch pro and its starting to act pretty weird, for instance, when i press the power button to put it in stand by the phone shuts off but the screen stays lite at a dark black screen and theres no way to get it off. also sometimes the keyboard doesnt work or the keyboard light doesnt come on when i slide it out. I took the bat cover off and i see 2 stickers, the on above the top right section of the battery and its white with red lines going through it, and the other one is in the circular hole on the very top left and it says "void" does either of these mean its gotten wet? I want to know before I go to my insurance

thanks a bunch guys, your always so helpful
