To determine if your computer is using Hyper-Threading technology:

2Click Hardware and click Device Manager.

3In the Device Manager window, click the plus (+) sign next to the processor type. If Hyper-Threading is enabled, the processor is listed twice.

You can enable or disable Hyper-Threading through the system setup program. For more information on accessing the system setup program, see page 78. For more information on Hyper-Threading, search the Knowledge Base on the Dell Support website at support.dell.com.

Booting to a USB Device

NOTE: To boot to a USB device, the device must be bootable. To make sure your device is bootable, check the device documentation.

To restart your computer to a USB device such as a memory key or CD-RW drive:

1Connect the USB device to a USB connector (see page 54).

2Shut down (see page 21) and restart the computer.

3Turn on the computer. When the DELL™ logo appears, press <F12> immediately.

If you wait too long and the Microsoft® Windows® logo appears, continue to wait until you see the Windows desktop. Then shut down your computer through the Start menu and try again.

NOTE: This changes the boot sequence for one time only. On the next start-up, the computer boots according to the devices specified in the system setup program.

4When the boot device list appears, highlight USB Flash Device and press <Enter>. The computer restarts to the connected USB device.

Turning Off Your Computer

NOTICE: To avoid losing data, turn off your computer by performing a Microsoft® Windows® operating system shutdown, as described next, rather than by pressing the power button.

NOTE: As an alternative to turning off your computer, you can set your computer to enter standby or hibernate mode. For information on power conservation modes, see the Tell Me How help file, or search for the keyword standby or hibernate in the Windows XP Help and Support Center. To access help files, see page 25.

1Save and close any open files, exit any open programs, click the Start button, and then click

Turn Off Computer.

2In the Turn off computer window, click Turn off.

The computer turns off after the shutdown process finishes.
