1-2 Dell Inspiron 3800 Reference and Troubleshooting Guide
•
Connectors for connecting external speakers, headphones, or an external
microphone to the computer.
•
A TV-out S-video connector and composite TV-out adapter cable that allows you
to connect a television to your computer. You can obtain the latest video drivers
on Dell's World Wide Web site at http://www.dell.com/filelib.
•
Ultra direct memory access (DMA)/33 data transfer protocol for Advanced
Technology Attachment (ATA)/integrated drive electronics (IDE) hard-disk drive
interface. Ultra DMA/33 allows data transfer rates of up to 33 MB/sec.
•
An integrated keyboard that includes two special keys that support the Windows
operating systems.
•
A Personal System/2 (PS/2)-compatible touch pad that provides full mouse
functionality. A set of left and right buttons, located below the touch pad, operate
like the left and right buttons on a mouse. You can also perform many pointing
functions by tapping the touch pad, which is positioned for both left- and right-
handed users. Click-and-drag buttonless functions are also supported.
An optional Dell™ DualPoint™ integrated pointing device is available, which pro-
vides a track stick in addition to the PS/2-compatible touch pad. The DualPoint
option also includes a second set of left and right buttons, located above the
touch pad. The track stick controls the cursor on the display screen and is posi-
tioned in the keyboard to allow you to move the cursor while keeping your fingers
in a typing position. You can also perform many pointing functions by tapping the
track stick. Click-and-drag buttonless functions are also supported.
•
Universal serial bus (USB) capability, which simplifies connecting peripheral
devices such as mice, printers, and computer speakers. The USB connector on
your computer's back panel provides a single connection point for multiple
USB-compliant devices such as keyboards, mice, printers, and computer
speakers. Also, you can connect and disconnect USB-compliant devices while
the computer is running.
NOTES: Windows NT does not support USB functions.
If you attach a USB device that was not included in your original system
configuration, you may need to install a specific driver for that device to obtain its
full functionality. Contact the manufacturer of the USB device for more
information.
•
A lithium-ion or nickel-metal hydride battery in the battery bay, with support for a
second battery in the media bay. The Dell ExpressCharge™ technology charges a
single lithium-ion battery in approximately 1 hour (when the computer is off or in
save-to-disk suspend mode).
NOTICE: Do not puncture or incinerate the battery. When your battery
no longer holds a charge, call your local waste disposal agency or
environmental agency for advice on disposing of the computer's
lithium-ion battery. The lithium-ion technology used in the battery is
significantly less hazardous to the environment than the lithium metal
technology used in some other batteries (such as watch batteries).
