1.4.8 System Memory
Memory is upgradeable from 8 to 64 MB, employing 8-/16-/32-MB 64-bit soDIMMs (Small Outline Dual
Inline Memory Modules). After installing the memory modules, the system automatically detects and
reconfigures the total memory size during the POST routines. The following lists important memory
specifications.
• Memory bus width: 64-bit
• Expansion RAM module type:144-pin, 64-bit, small outline Dual Inline Memory Module (soDIMM)
• Expansion RAM module size/configuration:
• 8MB (1M*16 x4)
• 16MB (2M*8 x8)
• 32MB (4M*16 x4)
• Expansion RAM module speed/voltage/package: 60ns/3.3v/TSOP EDO
• EDO and fast-page mode DIMMs may be used together in a memory configuration.
The following table lists all possible memory configurations.

Video Chip substitutability Yes
During power-on, system supplies 5V to video chip and read its register to determine
whether the video chip is 5V or 3.3V/5V type. If 5V video chip is detected, system
maintains video voltage at 5V; if 3.3V/5V video chip is detected, system switches
video voltage to 3.3V.

1.4.15 PCMCIA
PCMCIA is an acronym for Personal Computer Memory Card International Association. The PCMCIA
committee set out to standardize a way to add credit-card size peripheral devices to a wide range of personal
computers with as little effort as possible.
There are two type II/I or one type III PC Card slots found on the left panel of the notebook. These slots
accept credit-card-sized cards that enhances the usability and expandability of the notebook.
ZV (Zoomed Video) port support allows your system to support hardware MPEG in the form of a ZV PC
card.

1.4.22 Charger
To charge the battery, place the battery pack inside the battery compartment and plug the AC adapter into
the notebook and an electrical outlet. The adapter has three charging modes:
• Rapid mode
The notebook uses rapid charging when power is turned off and a powered AC adapter is connected to
it. In rapid mode, a fully depleted battery gets fully charged in approximately two hours.
• Charge-in-use mode
When the notebook is in use with the AC adapter plugged in, the notebook also charges the battery
pack if installed. This mode will take longer to fully charge a battery than rapid mode. In charge-inuse mode, a fully depleted battery gets fully charged in approximately six to eight hours.
• Trickle mode
When the battery is fully charged, the adapter changes to trickle mode to maintain the battery charge
level. This prevents the battery from draining while the notebook is in use.
