Why won't my Mac laptop power up?
In some cases, a Mac laptop won't power up when you press the power button. Typically, this means either the Power Manager is corrupt, or the battery is depleted and the computer is not properly connected to an AC power source. For information about fixing this problem, refer to Apple's article on Troubleshooting: My computer won't turn on.
Apple's knowledge base also has information on effectively using your portable computer's battery; see Lithium-ion Batteries.
