    power button to turn on the computer.
    CHARGE THE BATTERY—The battery charge may be depleted.
    1Reinstall the battery.
    2Use the AC adapter to connect the computer to an electrical outlet.
    3Turn on the computer.
     NOTE: 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 orange 
    or is a steady orange the battery charge is low or depleted. Connect the 
    computer to an electrical outlet.
    If the battery status light flashes green and orange, the battery is too hot to 
    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 orange, the battery may be defective. 
    Contact Dell (see Obtaining Assistance on page 193). 
    						
    							Troubleshooting123
    CHECK THE BATTERY TEMPERATURE—If the battery temperature is below 0° C 
    (32° F), the computer will not start up.

    Settings on page 46.
    RESEAT THE MEMORY MODULES—If the computer power light turns on but the 
    display remains blank, reinstall the memory modules (see Memory Problems 
    on page 119).
    Ensuring Sufficient Power for Your Computer
    Your computer is designed to use a 65-W or higher AC adapter.
    Using AC adapters that are less-powerful than 65 W will cause you to receive a 
    WARNING message.
    Docking Power Considerations
    Due to the extra power consumption when a computer is docked to the Dell 
    D/Dock, normal computer operation is not possible on battery power alone. 
    Ensure that the AC adapter is connected to your computer when the computer 
    is docked to the Dell D/Dock.
    Docking While the Computer Is Running
    If a computer is connected to the Dell D/Dock or Dell D/Port while the 
    computer is running, presence of the docking device is ignored until the AC 
    adapter is connected to the computer. 
    						
    							124Troubleshooting
    AC Power Loss While the Computer Is Docked
    If a computer loses AC power while docked to the Dell D/Dock or Dell D/Port,
