Dell Latitude D810: Low-Battery Warning Charging the Battery Removing a Battery

Low-Battery Warning Charging the Battery Removing a Battery: Dell Latitude D810

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. You can also turn the computer off and install a

second battery in the module bay. If the battery runs completely out of power, hibernate mode begins

automatically.

A low-battery warning occurs when the battery charge is approximately 90 percent depleted. The

computer beeps once, indicating that minimal battery operating time remains. During that time,

the speaker beeps periodically. If two batteries are installed, the low-battery warning means that the

combined charge of both batteries is approximately 90 percent depleted. The computer enters

hibernate mode when the battery charge is at a critically low level.

Charging the Battery

NOTE: The AC adapter charges a completely discharged battery in approximately 2 hours with the

computer turned off. Charge time is longer with the computer turned on. You can leave the battery in the

computer 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 light flashes alternately green and orange.

Disconnect the computer from the electrical outlet and allow the computer and the battery to cool

to room temperature. Then connect the computer to an electrical outlet to continue charging the

battery.
