Dell Latitude D510 - Manual (Page 88)

Ensuring Sufficient Power for Your Computer
Your computer is designed to use the Dell-branded 90-W or 65-W AC adapter.
Docking Power Considerations
Docking While the Computer Is Running
If a computer is connected to the 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/Port, the computer immediately goes into low-performance mode.
Undocking While the Computer Is Running
Your computer features Undock & Go™ technology that allows you to undock your computer without going into standby mode.
Printer Problems
Fill out the Diagnostics Checklist as you complete these checks.
Adjust the power properties — See " Power Management ."
Reseat the memory modules — If the computer power light turns on but the display remains blank, reinstall the memory modules.
NOTE: Ensure that your battery is charged before attempting to undock your computer.
NOTE: When you undock your computer from the docking device, a solid black screen may appear, depending on the type of video adapter that you are
using. This is expected behavior and does not indicate that a problem exists. See your docking device documentation for more information on undocking
your computer.
CAUTION: Because the computer may not automatically go into standby mode when it is undocked, be sure the settings in the Power Options
control panel do not prohibit the computer from going into standby mode. If you change the Power Options control panel to prohibit the computer
from going into standby mode, you greatly increase the chances of causing your battery to wear down quickly or causing your computer to
overheat.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTE: If you need technical assistance for your printer, contact the printer's manufacturer.
