Power failure for HP Pavilion A6600F

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.

    Thanks for the solution. I checked with an alternative power supply and have had no headway. It might be about time to discover options in terms of warranty...or whole motherboard replacement....thanks again - David

>> I might have to test an alternative power supply to rule out the existing power supply.

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

If 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.

Shut down and unplug your computer.

Unscrew the two screws on the back of the case and open the side panel of the case.

Remove your RAM memory stick(s) from their holders.

Replace them into their respective holders again.

Ensure they are seated properly and clipped in.

Plug your power cord back in and see if your computer will boot. You can leave the side panel off just don't stick your fingers in there when it's plugged in.

If the problem persists, then you may have one or more bad RAM memory sticks.
If you have more than one stick installed, try removing one and reboot.

Always unplug your PC before removing RAM sticks and try not to touch the copper contacts on the RAM stick to avoid static damage, they can be delicate.

Good luck and please post back about how you make out.
