Battery Pack Charge Gauge
Before you install the high-capacity battery pack, press the status button on
the battery charge gauge to illuminate the charge-level lights. Each light
represents approximately 20 percent of the total battery charge. For
example, if the battery has 80 percent of its charge remaining, four of the
lights are on. If no lights appear, the battery has no charge.
Low-Battery Warning
NOTICE: To avoid losing or corrupting data, save your work immediately
after a low-battery warning. Then connect the computer to an electrical outlet.
If the battery runs completely out of power, hibernate (suspend-to-disk) mode
begins automatically.
A pop-up window warns you when the battery charge is approximately 90
percent depleted. For more information on low-battery alarms, see "Power
Management" in your online User's Guide.
