Knowing the Parts 1 2 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-OnSelf-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. 2 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. 3 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. 4 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 purchased as a single unit. 5 Central Processor Unit (CPU) Some Notebook PC models feature a socketed-processor design to allow upgrading to faster processors in the future.

End-user removal of the CPU or hard disk drive will void the warranty. 6 Cooling Fan The cooling fan turns ON or OFF depending on temperature threshold settings. 15
