MacBook Pro wont start, but the battery is fully charged?
First off, I want to mention that the battery in my macbook is old and runs out of its charge after about 1 hour of normal use, I need to get a new one but I don't think that will solve my current issue, which is that it just wont start.
Last night as I was going to turn my computer off, it told me about some updates that could be installed before shutdown, including the Mac OSX 10.6.7 update. So I let it install everything without plugging in the power cable because the battery was fully charged. After installing the updates the computer turned itself off.
Today, it started up as normal, but the meter that shows how much more charge is in the battery showed 20 hours, which is nonsense. I expected it to change and started using the computer as normal (surfing). The battery meter stayed at 20 hours, and then suddenly the computer went into sleep mode and the lights on the battery went from all on to just the one flashing. So I plugged in the cable and waited, and after about 20 minutes the lights on the battery were all on again so I tried to turn it on, but it wouldn't start.
I figured something had gone wrong so I pressed the power button for a few seconds and the computer turned off.
Now it wont start at all, even though the battery is fully charged. I tried restarting the SMC (power button for 5 seconds) but to no luck.
Edit: Just for clarification, NOTHING happens when I press the power button.
Update
I did not mean to sound rude, I was just stating the facts, sorry if I offended anyone.
Anyway: I went to the local mac dealer to let the tech there have a look, explained what was wrong and the tech tried pressing the power button and, of course, it booted normally. This didn't exactly help with my frustration but at least it works now, for whatever reason...
Ordered a new battery though, since I suspect the old one had something to do with it...
Es esta una buena pregunta?

Do you know the wattage of the AC adapter he was using? My guess is that you were using a 65 watt AC adapter and he was using an 85 watt AC adapter. The 85 watt allowed the MacBook Pro to boot, but the 65 watt did not. I have seen that happen more than a few times.

I don't know, but I have two adapters at home and I tried both with no success before the tech worked his magic. They both work fine now though... How do I find out the wattage on my adapter?

Just look on the side of the adapter and it should say something like "Apple xxW Portable Power Adapter".

The adapters i have are both 60W, but they work fine now. Could it be that the techs adapter was 85W and worked sort of like a defibrillator which managed to get my computer out of its dead state and make it work again? I'm no electrical engineer but that seems unlikely, albeit cool. :)

Yep, that's probably what happened. I have seen this quite a few times.
