My daughter has a Dell Inspirion 1520 Laptop. She knocked over a glass of water on it. It would not power on. I took the back doors off and took the keyboad out. I dried it out the best I could with a hair dryer (on cool). Put it back together and it booted up and opended windows. Everyone was happy. It ran for 5 minutes and then shut itself off. It is now totally dead. Any suggestions? Thanks--Mark
