Power sources

Your computer can draw its operating power from two different sources. You choose which power source to use.

nMain battery: Your computer’s main power source is a nickel-metal-hydride battery. The battery provides power for up to 6 hours of work (depending on the battery conservation features you choose).

nAC power: You can run your computer from any standard electrical outlet by plugging in the power adapter.

Your computer also has backup batteries that maintain the contents of RAM while you replace the main battery. The backup batteries do not provide enough power to run the computer.

These power sources are described in more detail in the following sections.
