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 spring loaded latch (lock 1) automatically locks the battery pack when inserted but must be rein-
forced with a manually operated latch (lock 2). Usage details are described in the battery section later in
this manual.
Battery Pack
The battery pack is actually combined with the Notebook PC’s surface in order to reduce thickness.
When the battery is released, the surface and battery pack will be seen as a single unit. The battery pack
cannot be further disassembled and must be replaced as a single unit.
Memory (RAM) Compartment
The memory compartment contains one or two (depending on model) expansion slots 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 accord-
ingly 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 au-
thorized retailers of this Notebook PC to ensure maximum compatibility and reliability.
Mini-PCI Compartment
Optional expansion cards can be installed in the mini-PCI compartment. An optional wireless LAN
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.
Audio Speakers
The built-in speaker allows you to hear audio without additional attachments. The multimedia sound
system features an integrated digital audio controller that produces rich, vibrant sound (results im-
proved with external stereo headphones or speakers). All audio features are software controlled.
Central Processor (CPU)
Some Notebook PC models feature a socketed-processor design to allow upgrading to faster processors
in the future. Some models feature a ULV design for compactness and may not be upgraded. Visit an
authorized service center or retailer for information on upgrades.
WARNING! End-user removal of the CPU or hard disk drive will void the warranty.
