92 Troubleshooting
RESEAT THE MEMORY MODULES —If the computer power light turns on but the display remains blank,
reinstall the memory modules (see "Memory Problems" on page88).

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.
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, the computer
immediately goes into low-performance mode.
