Is this android? If so there should be a option there on the unlock screen somewhere to reset the lock pattern using your email login attached to that device.

If all else fails maybe a pc repair shop can help.

If there is water on the board dab it dry with a paper towel and leave the cover off for a while in front of a fan to let it dry out.
