My Dell Inspiron 1525 wont turn on

Ok so I left my laptop on the bed and there was a water bottle near it, when I went away the water bottle fell over and most of it went into the sheets but a decent amount went under the laptop I think, and so its been like 5 months and I gave up, then yesterday I plugged it in and it turned on! it worked for em to log on and I started to delete a picture and then it shut off and wont turn on again. I really hope it isnt done for, what do I do?
