Problem with power button on a Precision M70

Specs: Windows XP sp3, Fast / Lots
Is there a fix for the power button on an m70? I have to essentially mash down on it in a very specific way (with more pressure closer to the middle of the laptop, in other words the Left side of the button. I took off the cover that holds the button itself to see just how/why it doesn't work. There is a little plus sign in plastic underneath the button that is part of the plastic molded button that needs to make enough contact pressure to the real button (the button physically ON the board).

With the cover off, of course I can very gently push on the real power button on the exposed board of the machine and turn it on just fine. Oh, and turning it off for some reason is never an issue. So I was able to successfully recreate the issue the plastic button causes by VERY gently, as in just barely any pressure, pushing the button down, I can sometimes get it to power on enough for JUST the power light to light up, and something click inside, which I am assuming is the hard drive spinning up for, again, just a second, then the machine turns back off. Keep in mind, it is not "starting up" completely, but just for literally about one to two seconds.

I GREATLY appreciate any leads on how to best fix this problem. one solution I would like to try is to elevate the power button board enough to not have to press the plastic power button down as hard when the cover is on. Here is the unit I am talking about: I know it is cheaper elsewhere, but just to show you what I am talking about. I figure to try to put one or more washers under the screw on the right to lift it up and see if that helps. ANY OTHER IDEAS ARE VERY WELCOMED HERE. Please help with this, as I need to fix it up for a client who really needs ths machine asap.
Thanks a million again,

Replace the power button board may fix it but it could be the connector below that board.

Thanks Jefro, I'll take a look at that possibility tomorrow. Will post again any update.
