Charge Gauge

Before you insert a battery, 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 mode begins automatically.
A pop-up window warns you when the battery charge is approximately 90 percent depleted. For more information about low-battery alarms, see

Charging the Battery
The AC adapter charges a completely discharged battery to 80% in about 1 hour and to 100% in approximately 2 hours when the computer is turned off.
NOTE: With Dell™ ExpressCharge™, when the computer is turned off, the AC adapter charges a completely discharged battery to 80% in about 1 hour
and to 100% in approximately 2 hours. Charge time is longer with the computer turned on. You can leave the battery in the computer for as long as you
like. The battery's internal circuitry prevents the battery from overcharging.
When you connect the computer to an electrical outlet or install a battery while the computer is connected to an electrical outlet, the computer checks the
battery charge and temperature. If necessary, the AC adapter then charges the battery and maintains the battery charge.
If the battery is hot from being used in your computer or being in a hot environment, the battery may not charge when you connect the computer to an
electrical outlet.
The battery is too hot to start charging if the
computer and the battery to cool to room temperature. Then connect the computer to an electrical outlet to continue charging the battery.
