Central Processor Unit (CPU) Compartment
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 au-
tomatically detects the amount of memory in the system and configures accordingly. 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 ex-
pansion modules from authorized retailers of this Notebook PC to ensure maximum compatibility and reliability.
