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.
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.
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.
Battery Lock - Spring
The spring battery lock is used to keep the battery pack secured. When the battery pack is inserted, it will
automatically lock. To remove the battery pack, this spring lock must be held in the unlocked position.
Battery Lock - Manual
The manual battery lock is used to keep the battery pack secured. Move the manual lock to the unlocked
position to insert or remove the battery pack. Move the manual lock to the locked position after inserting
the battery pack.
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.
