PLEASE HELP my Dell laptop E6410 will not turn on

I got my laptop a bit wet today from the rain and when I brought it home nothing turned on. No fan, no hard drive, nothing at all. I tried the "take out battery and adapter and hold the power button for 30 secs" but that only made the power LED light come on and still nothing else. The battery light flashes orange sometimes then goes away when the battery is in and the power light stays on. When I first put the battery in the light was kinda white, then light purple and then it went to solid orange to flashing orange. Thank you all so much for the help.

P.S. When I put everything in and the power light does come on, the power button is useless and will not turn off the laptop
