Introduction
This chapter provides information about the major hardware and software features of
your computer, as well as available upgrades.
Hardware Features
Your Dell™ Inspiron™ computer has the following hardware features:
• An Intel
®
microprocessor incorporating the latest processor technology.
• An ATI video controller with an accelerated graphics port (AGP 2X), 4 or
8megabytes (MB) of video memory, 3D assist, Motion Pictures Experts Group
(MPEG)-2 assist, and a flicker-free TV-out S-video connector.
• An active-matrix extended graphics array (XGA) or super extended graphics array
(SXGA) color display.
• Extended battery power with a lithium-ion main battery in the MegaBay™ and an
optional second battery that you can use in the media bay to double battery life.
You can expect 2.0 to 3.5 hours of battery life with a single battery, or 4 to 7 hours
of battery life with two batteries.
NOTES: Battery performance features such as charge time, operating time, and
life span can vary according to the conditions under which the computer and
battery are used.
The battery is designed to work only with Dell Inspiron 7500 computers. Do not
attempt to use the battery with other computers.
CAUTION: 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).
• Cache memory that enhances the speed of many microprocessor operations by
storing the most recently accessed contents of system memory. Your computer
has 32 kilobytes (KB) of internal Level 1 (L1) cache on the microprocessor, and
