My MBP went to sleep at work y'day as the battery went low. Today (with charger plugged in) i press the keys but no wake. I pressed the cap lock, this usually shows green, this time nothing. So i think the battery is completely dead. So I pull the battery pout, and plug int he power lead, try hitting the power up button, nothing. It makes a small whirl noise but thats it. No power up. I insert a OSX installation disc in the drive. Hot the power button with C held down. Nothing. Tried holding the power button down for 5 secs to hard shut. It makes a sound from the CD drive bay likes its trying to access it but nothing else, no start up. Even tried the Command + ctrl + on button to do a hard reset, nothing. Any ideas to get this going?
