power cord to reset it.

battery until at least one indicator light is glowing continuously.

removing the battery, and holding down the power (®) button for at least 5 seconds.

that it is compatible with your computer. See whether removing it allows the computer
to start up (see “Installing Additional Memory” on page 82).
