replace the battery or connect your computer to an electrical outlet.
After the first low-battery warning, if no input/output (I/O) activity occurs within 75 seconds, the computer
activates suspend-to-disk mode. Once suspend-to-disk mode is activated, no further power is consumed. If
the computer has no suspend-to-disk partition, the computer enters suspend mode. The computer can
preserve data for several hours in suspend mode.
NOTICE: Never turn off the computer while the drive access light is on. Doing so could
cause data loss. Instead, close all of your application programs before you turn off the
computer.
Second Low-Battery Warning
The second low-battery warning—a steady amber battery light—occurs when you have about 5 minutes of
battery life left under current conditions and the computer is not connected to an electrical outlet.
After the second low-battery warning, if no further I/O activity occurs within 15 seconds, the computer
activates suspend-to-disk mode. If there is no suspend-to-disk partition, the computer enters suspend mode.
The computer can preserve data for several hours in suspend mode.
If the computer is already in suspend mode when a final low-battery warning occurs, the computer activates
suspend-to-disk mode immediately. If suspend-to-disk mode has been disabled, the computer reenters
suspend mode.
NOTICE: To avoid losing data (and possibly corrupting data areas on your hard-disk
drive), save your work immediately after a second low-battery warning. Then connect
your computer to an electrical outlet, or place the computer in suspend mode. If the
battery runs completely out of power, the computer shuts off without properly closing
any open files.
Charging the Battery
Each time you connect the computer to an electrical outlet or install a battery in a computer that is connected
to an electrical outlet, the computer checks the battery's charge. The AC adapter charges the battery (if
needed) and then maintains the battery's charge.
NOTE: For maximum battery performance, charge the battery only at normal room temperature.
If two batteries are installed in the computer, the AC adapter first charges the battery in the battery bay, then
the battery in the modular bay.
When installed in a computer connected to an electrical outlet, the battery immediately starts charging. The
green power light remains steady while the AC adapter charges the battery. The power light starts blinking
when the Dell ExpressCharge™ cycle is complete. While the power light is blinking, the AC adapter provides
a trickle charge to bring the battery to full capacity. The power light continues to blink until you remove the
battery or disconnect the computer from its electrical outlet.
NOTICE: If the battery is hot from being used in your computer or being in a hot
environment, follow these precautions:
