Nokia Nseries :: N97 Lights Light Up When Battery Is In?

Recently, my Nokia N97 had water leaked into the phone while it was on. I had it in a friend's bag, and it sat at the very bottom, when his drink bottle leaked, causing half of the phone to be submerged for around 10 minutes, before we realized what had happened.

His own phone was also submerged, but he managed to get it working fine. Mine however, turned off, or seemed to go black in the screen, and had water filled up in most of it. I immediately took the battery out, wiped down the phone and placed it into a bowl of rice. In three days, most of the water disappeared from the phone, except for a small blot, which left a white patch when it dried under the screen. Now, when I put the battery in, the phone lights up at its buttons on the screen such as the menu button, and the red light of the camera.
