Battery full, will not start up? Suggestions?

Question

Greetings,
  I have my trusty ol' 15' MBPro..which, all of a sudden will not boot. Battery meter is all lit up. The last few days, it has tried to start, even make it to main page once...then goes blank (no power). I have had install disc in once..trying to run utility..same thing..powers down. Now, it won't even try. Nothing happens when I push start button. I'm in remote southern Mexico, so...there are no technicians here. I've replaced the battery a couple of times in it's lifetime, but..as I said..it shows as fully charged. Any ideas or solutions would be appreciated. Thanks.

Making good sense, Dave...since the charger is showing a green light and the battery meter shows full charge, but the unit won't start up to the login page, and won't start on the install disk, it sounds like a fault in the startup manager.  When you say won't power up, am I understanding correctly that you mean it starts to power up and then stops, since you describe not getting past the initial startup page?  If that is the case, have you tried starting up holding the Option key to take control of the startup manager?
If you are not getting any startup at all, that is, no response at all, it sounds more like a failure in the logic board, or charging circuitry.  The unit should be able to start on line power even with a dead battery, as long as the battery is in place...there are enough users on here with dead battery issues to indicate that it should startup as long as it gets power from somewhere.
The question of the line power should not be an issue since the chargers are rated 110-240 volts at 50-60 Hz, and as long as you are in that range you should still be seeing 12 volts DC out of the charger.
