34 Operation
Start the System Apply power to the computer. The computer performs a Power On
Self Test (POST). The processor board, memory, keyboard, and
certain peripheral devices are tested.
Use a monitor if you want to view the progress of the POST and
initialization of accessory devices. The monitor displays the startup
dialogs for the operating system that is installed.
If your system does not start, or you notice other anomalies, refer to
the System Troubleshooting chapter.
Reset the System To reset the computer, press Ctrl+Alt+Delete on an attached keyboard
and follow the operating system instructions.
After resetting, the computer begins the Power On Self Test (POST).
During a reset, the computer:
• clears RAM.
• starts the POST.
• initializes peripheral devices, such as drives and printers.
• loads the operating system, if installed, or starts a Windows
session.
Universal Serial Bus (USB)
Ports The universal serial bus (USB) is an external bus standard that
supports data transfer rates of 12 Mbps (12 million bits per second).
The 200R computer supports USB 2.0 in the Windows operating
system with data transfer rates of 480 Mbps.
You can connect multiple peripheral devices to the USB ports such as
a mouse, modem, and keyboard. USB also supports Plug-and-Play
installation and hot plugging.
For information on installing or using USB, refer to the documentation
for your USB peripheral device.
TIP
Many USB devices only work with Windows XP or Windows
2000 operating systems because these operating systems have
native USB drivers. Make sure the selected USB peripheral has
software drivers available for your target operating system.
