HP Laptop Stripped down but still wont power up, no beeps or anything

I have a customers HP NC6000 and it was reported to be the display going off after sounding like it's booting but it powers for about 5 or 6 seconds and other on Ebay are being sold for the same reason. Is it giong to be the Main board or the Processor or the Internal Power?

I have removed the HDD, DVD RW, Battery, Modem, Keyboard, Memory and the Wireless (PCMCIA card) - the only things left is the daughter board the Modem plugs into and the Processor I think. I tried another Power Brick with the battery disconnected and the result is the same. What do you think? All things repairable with knowledge, time and money, (patience) but HP website say the Main board is MORE THAN £400 -

Ebay has boards but I want to spend on what is needed instead of buying to find it is wrong wasting time and money.
Thanks,

The instructions are great - especially with video. Is it possible the RTC battery could do this? The processor was replaced by an apparently tested working used 1.6Ghz (Dothan) -same model and it lit the charge button which usually stay on for a few seconds and power led came on green for a bit when switch pressed. It seemed intermittant but gone again.
Two possibilities i thought of - The 'new' processor burnt out as well or it has some time to build a charge in the RTC when it was dissassembled which has dissapated again.

Well thanks but the customer decided £120 to have it repaired was reason to get a new one (eventually/ near future). Had job of transferring >20G of photos etc. Any way after pulling it apart then re-assembling it every time, the system seemed to boot (with the new processor) but just the once for a few minutes to the Login screen and then went back to it's 5 or 6 second Charge light on but nothing else. So it doesn't even seem to charge when playing up-

If I did'nt try to boot when re-assembled the Charge LED would stay on for an hour maybe according to the battery status which says to me it worked fine if power not pressed, would have loved to know what the cause was - maybe Button board or LED board or Main board - who knows?

Isn't it Odd the charge LED comes on for even a few seconds when power button is pressed?

Will award points soon. (?)
Both of you were correct and helpful in you answers. Thanks - hope the points split was acceptable.
