Power failure for HP Pavilion A6600F

\015 Machine refuses to boot, when power button is depressed there is no response. LED on power supply indicates PC is receiving power and all other electrical items, EG: monitor, work fine. Running XP home, SP3 I have seen similar problems with other machines. My friend has this pre-built system designed by HP (model Pavilion a6600f) I presume all components are origional and/or specific for that model. Power box indicates its getting proper power and there are no problems with my room's electrical outlets. Somehow, my friend manage to spill a significant amount of water on his computer just before he dropped it off at my house. The casing of the computer has large ventulation holes on the side - an ounce or so of water had gotten on the motherboard and respective components. I left the computer off for about eight hours - hoping that would be enough time to dry off the system. (I had a computer that was internally covered with condensation buildup of ice vapor - which melted into water when I brought it into my house, I let that computer dry for about the same time and had no problems.) I've checked all the wiring and found no error. I've reduced the amount of components the power box was supplying - down to the motherboard. I've removed all external connections, reset the bios, reset the bios password manually. I've checked to see if the system would run without the ram - no effect. I've manually tried starting the system using a metal screw-driver to no effect. If it comes down to it - I might have to test an alternative power supply to rule out the existing power supply. There's no obvious detail of a previous power conflict resulting in burnt capacitors or significant other. (I've had that happen to one of my computers several years ago.) If I was more curious I'd take the board out of the computer and have a thorough examination for possible burns. There's no obvious debres or foreign objects left on the motherboard or in the computer - nor floating wires to complicate the physical process' of the computer. The dust collection is at a minimum - not enough to cause cpu or systematical overheat. The motherboard is fully integrated in terms of video graphics, sound, and ethernet. It's designer is Foxconn - the design appears efficient and lower-end. When taking a computer from one power source to another (from one house to another) complications can arise. Power failure can happen - I've seen it happen before. I hope it's not the water that killed the system.\015

\015\012That should be your next step. Just connect the "temporary" power-supply to the motherboard and the fan on top of the CPU.
\015\012Don't connect to the floppy-drive, the CD-drive, the disk-drive.

\015\012If you remove all the RAM, and start it, does it "beep" (to complain about the lack of RAM) ???? If not, then the motherboard (or the power-supply) is the problem.

My HP Pavilion dv9700 was over heating and would shut off. Then it wasn't over heating and would shut off. Now it won't turn on at all. The power cord is working and the lights go on for a second while I am pushing the button to turn it on, but the computer won't turn on. HP told me the problem was the motherboard. Do you think that's really the problem or could it be something else?

Also the yellow light that shows whether its loading is not lighting up.
