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 articles on troubleshooting a MacBook, MacBook Air, or MacBook Pro that won't turn on, or troubleshooting a PowerBook G4, iBook, or iBook G4 that won't turn on or start up.
Apple's knowledge base also has information on effectively using your portable computer's battery; see Lithium-ion Batteries.
