Troubleshooting 123
CHECK THE BATTERY TEMPERATURE — If the battery temperature is below 0° C
(32° F), the computer will not start up.
TEST THE ELECTRICAL OUTLET — Ensure that the electrical outlet is working by
testing it with another device, such as a lamp.
CHECK THE AC ADAPTER — Check the AC adapter cable connections. If the AC
adapter has a light, ensure that the light is on.
CONNECT THE COMPUTER DIRECTLY TO AN ELECTRICAL OUTLET — Bypass power
protection devices, power strips, and the extension cable to verify that the
computer turns on.
ELIMINATE POSSIBLE INTERFERENCE — Turn off nearby fans, fluorescent lights,
halogen lamps, or other appliances.
ADJUST THE POWER PROPERTIES — See "Configuring Power Management
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.
