534. Using the Notebook PC

System Memory Expansion

Under some circumstances, you may find additional memory is required. This is particularly true as

applications become more complex. Expanding system memory is one method of increasing system

performance by decreasing hard disk access. The Notebook PC comes with 64MB 64-bit high speed

SDRAM built-in. One standard 144-pin SO-DIMM (Small Outline Dual Inline Memory Module) socket

is available for system memory expansion using common 3.3 Volt 100MHz SDRAM SO-DIMM

modules. Currently, SO-DIMM memory sizes are available in 16MB, 32MB, 64MB, or 128MB for

each module. The maximum memory size you can expand the Notebook PC to is 192MB using a

128MB SO-DIMM. The BIOS will automatically detect the amount of memory in the system and

configure 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. Only purchase expansion mod-

ules from your authorized retailer to ensure compatibility and reliability. The memory module must be

installed by a certified Notebook PC technician.

IMPORTANT: Be aware that stores may also carry EDO DRAM. EDO DRAM is not sup-

ported on this Notebook PC.

Processor Upgrades

Please visit your authorized service center or retailer for upgrades. The Notebook PC uses an Intel

microPGA2 socket in order to support future processor upgrades. Current processors are Pentium

III

(with 256KB level 2 cache built-in) from 450-700MHz+ and Celeron (with 128KB level 2 cache built-

in) from 450MHz-600MHz+. Faster processors are just around the corner.

Thermal Power Control

There are three power control methods for controlling the Notebook PC’s thermal state. These power

control cannot be configured by the user and should be known in case the Notebook PC should enter

these states. The following temperatures represent the chassis temperature (not CPU).

• The fan will turn ON for active cooling when temperature exceeds 70˚C (158˚F) when AC power is

used and 80˚C (176˚F) when only using battery power.

• The processor will throttle (decrease CPU speed) for passive cooling when temperature exceeds

70˚C (158˚F).

• The system will shutdown for critical cooling when temperature exceeds 90˚C (194˚F).
