I have a Dell Inspiron 6400 that had water spilled on the keyboard and would not boot after this. I removed the motherboard and after inspecting it I saw a chip that was fried. I ordered a new motherboard (from e-bay)and replaced it. I still have the same problem … it powers on for 2 seconds … the hard drive nor fan comes on and then it shuts down. I get no display response from the power on. Any suggestions?
