Laptop not turning on

[Fakhrimf54]

I've juts spilled some water on my laptop and it went off directly . I quickly unplugged the charger and tried to force stop the laptop but it wouldn't work. However the green power button stayed on (although dim) for a good couple minute. Tried to dry as much of the liquid that was on the surface and turned the laptop upside down to dry a little more as some seeped out of the keyboard.

I've left it to dry for a couple hours and now whenever I tried to turn the laptop on the power LED on the side turns on for 5 seconds with a pause of 3 seconds.

- What does the blink mean? 

- Is there anyway I personally could fix it? 

- Unfortunately my warranty has expired, so if I can't fix it myself and have to get it repaired, how much would it cost? Or is it done and would be better to get a new one.

Thanks a lot in advance
