For what it is worth, I have managed to repair two of these so far, both the with the problem of only booting while pushing on or around the processor socket. I found that when not pushed on, the board lost the core voltage (1.4 V to the processor). This is controlled by a Maxim chip on the bottom of the board by the power input jack. Looking at the leads of this chip under a binocular scope, I could see several connections with hairline fractures at the chip. The Maxim chip is a core voltage control chip, and is unusually high off the boardwith very soft solder connections. The repair consisted of very carefully (under the scope with a very sharp tip iron) reflowing the solder connections that looked cracked. Both boards have been working perfectly since.

May I ask you to make a short guide on the fixing process with pictures? I mean I'd like to repair it myself if it is possible, but as a totally newbie as of circuits I will need every point of information. Even if you may write a little bit more detailed reply could help. :S
Please!

There is actually a very good discussion of this problem towards the end of the LONG thread at the HP user forum in the attached link. Several people have posted pictures of this. The link is below:
