4-2 Dell Dimension 900 System Reference and Troubleshooting Guide
The Power Schemes tab allows you to select the power scheme (Always On,
Home/Office Desktop, or Portable/Laptop) and power mode settings for your com-
puter. For Windows 2000 and Windows Me, the following options are available for
each power scheme setting:
• Turn off monitor — Turns off the monitor so that the system uses less power.
You can press any key to turn on the monitor. The Windows desktop is restored
exactly as it appeared before the monitor was turned off.
• Turn off hard disk — Turns off the hard-disk drive so that the system uses less
power. You can press any key to turn on the hard-disk drive. The Windows desk-
top is restored exactly as it appeared before the hard-disk drive was turned off.
• System standby — Turns off the monitor, stops the hard-disk drive, and turns off
other internal devices so that the computer uses less power. When the system
resumes from standby mode, the Windows desktop is restored exactly as it
appeared prior to entering standby mode.
NOTE: The system may take several seconds to resume operation from the power
scheme settings.
The Advanced tab allows you to display the Power Management icon on the
Windows 98 taskbar and the Power Options icon on the Windows 2000 and Win-
dows Me taskbar. You may also select the option to have a password prompt appear
when the system resumes from standby mode. For Windows 2000 and Windows
Me, you may set the system to power off or to enter standby mode when you press
the power button.
For Windows 2000 and Windows Me, the following additional tabs are included in the
Power Options Properties window:
• The Hibernate tab allows you to enable hibernate mode support and displays
available disk space for hibernation.
• The UPS tab displays the status of the uninterruptible power supply (UPS), if
installed.
Reinstalling Drivers
All of your system’s drivers for Dell-installed devices are operative when you receive
the system—no further installation or configuration is needed. However, if you ever
need to reinstall any of these drivers, the driver files are provided on the Dell
Dimension ResourceCD.
Device problems can often be corrected by reinstalling the appropriate drivers. Also,
hardware manufacturers frequently provide updated drivers that support feature
enhancements or that correct problems. Obtain updated drivers for products
purchased from Dell at the support section of the Dell World Wide Web site
(http://support.dell.com).
NOTICE: Drivers available on the Dell Web site have been validated for
correct operation on Dell systems. Installing drivers obtained from other
sources may cause errors or performance degradation.
