Hard Disk Drive Compartment
The hard disk drive is secured in a compartment. Hard disk drive upgrades are to be done by authorized
service centers or dealers only.
Battery Lock
The battery lock is used to keep the battery pack secured. Usage details are described in the battery
section later in this manual.
Battery Pack
The battery pack is automatically charged when connected to an AC power source and maintains power to
the Notebook PC when AC power is not connected. This allows use when moving temporarily between
locations. Battery time varies by usage and by the specifications for this Notebook PC. The battery pack
cannot be disassembled and must be replaced as a single unit through an authorized vendor.
Stereo Speakers
The built-in stereo speaker system allows you to hear audio without additional attachments. The multi-
media sound system features an integrated digital audio controller that produces rich, vibrant sound
(results improved with external stereo headphones or speakers). Audio features are software controlled.
Mini-PCI Slot
An optional expansion card can be installed in the mini-PCI compartment. An optional wireless LAN
mini-PCI module enables you to stay connected to your LAN while “roaming” to meeting, conference
rooms, or other office locations. Full-time, real-time access to email, Internet, and network resources
means not only an expanded office space, but also greater productivity.
Memory (RAM) Compartment
The memory compartment provides expansion capabilities for additional memory. Additional memory
will increase application performance by decreasing hard disk access. The BIOS automatically detects
the amount of memory in the system and configures CMOS accordingly during the POST (Power-On-
Self-Test) process. There is no hardware or software (including BIOS) setup required after the memory
is installed. Visit an authorized service center or retailer for information on memory upgrades for your
Notebook PC. Only purchase expansion modules from authorized retailers of this Notebook PC to
ensure maximum compatibility and reliability.
Emergency Shutdown Button
In case your operating system cannot properly turn OFF or restart, the shutdown button can be pressed
with a straightened paper clip to shutdown the Notebook PC.
Name Card Holder
The Notebook PC has a name card holder glued to the bottom of the Notebook PC to hold identification
information on the user in case the Notebook PC is found by others.
