Using battery alarms

You can configure the computer to warn you when the battery is running low. There are two alarms available:

❖Low Battery alarm

The Low Battery alarm gives you an audible warning when the computer’s battery has about 10 percent of its charge remaining. You can set the volume (off - low - medium - high) for the low battery alarm.

❖Critical Battery alarm

The Critical Battery alarm notifies you when the computer’s battery has about five minutes remaining. You can choose whether the Critical Battery alarm gives you an audible and/or a visible warning.

To modify the default settings in the Power utility, click Start, point to Settings, and click Control Panel. Double-click the Power Saver icon, then click the Alarms tab.

Changing the main battery

When the battery runs out of power:

❖If AC power is available, run the computer from the AC source while the battery charges, or shut down the computer and allow the battery to recharge.

❖If you have charged a spare battery, change the battery.

CAUTION: Handle battery packs carefully to prevent damage to the casing. Avoid dropping the battery or mishandling it. Also, be careful not to short-circuit the battery terminals.
