Compaq Presario V5000 = no boot but will charge battery.

Hey Gang,

I have a Compaq Presario V5000 that will not power up. Fans and drives don't spin up. The odd thing is it will charge the battery when hooked up to the power supply. The orange lightning bolt is solid until it is fully charged then it blinks. I have a second power supply and I get the same result.
The laptop does nothing when I remove the battery and try to run in directly on the power supply. I have re-seated the memory, hard drive, DVD drive, WiFi, keyboard, touchpad, monitor, audio board and replaced the power button board.
I also checked the power level going all the way to the processor and all is well.
I am at a loss!

I guess the only thing left to do is replace the motherboard or processor.
Any tips or suggestions?

I tried the tips above with no success. I replaced the motherboard wi the same model and it now functions correctly. Issue resolved. Thanks for the tips though!
