Battery operating time (the time the battery can hold a charge) decreases
over time. Depending on how often the battery is used and the conditions under
which it is used, you may need to purchase a new battery during the life of your
computer.
C HECK THE BATTERY STATUS LIGHT — If the battery status light flashes amber
or is a steady amber, the battery charge is low or depleted. Connect the

charge. Shut down the computer, disconnect the computer from the electrical
outlet, and then let the battery and computer cool to room temperature.
If the battery status light rapidly flashes amber, the battery may be defective.
