ÂIf you recently installed additional memory, make sure that it is correctly installed and that it is compatible with your computer. See whether removing it allows the computer to start up (see page 57).

If the display suddenly goes black or your system freezes

Try restarting your system.

1Unplug any devices that are connected to your PowerBook except the power adapter.

2Hold down the Command (x) and Control keys and press the Power button (®) to restart the system.

3Let the battery charge to at least 10 percent before plugging in any external devices and resuming your work.

To see how much the battery has recharged, look at the Battery status icon in the menu bar.
