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.

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-in-use mode, a fully depleted battery gets fully charged in approximately six to eight hours.
·
Trickle mode The adapter charges the battery pack for two hours using trickle current 17 ± 3mA, then shifts to 1/10 duty pulse trickle charge to keep the battery capacity at 100%.

System Introduction

MultiBoot The system can boot from the FDD, External FDD, HDD, or CD-ROM. The user can select the desired booting process to boot the system. If the CD-ROM is bootable, the BIOS will override the other process to boot the system directly. Power Management This computer has a built-in power management unit that monitors system activity. System activity refers to any activity involving one or more of the following devices: keyboard, mouse, floppy drive, hard disk, peripherals connected to the serial and parallel ports, and video memory. If no activity is detected for a period of time (called an inactivity time-out), the computer stops some or all of these devices in order to conserve energy. This computer employs an innovative power management technique called Heuristic Power Management or HPM. HPM allows the computer to provide maximum power conservation and maximum performance at the same time. Power management methods used by most computers are timer-based. You set inactivity time-out values for the display, hard disk, and other devices. The computer then "sleeps" when these timeouts elapse. The problem with this is that no two users are alike. Each of us has his or her own habits when using the computer, which makes timer-based power management ineffective. With HPM, your computer manages its power according to the way you use your computer. This means the computer delivers maximum power when you need it, and saves power when you don't need the maximum -- all without your intervention. There are no timers to set, because the HPM system figures out everything for you.

HIBERNATION MODE
In hibernation mode, all power shuts off (the computer does not consume any power). The computer saves all system information onto the hard disk before it enters hibernation mode. Once you turn on the power, the computer restores this information and resumes where you left off upon leaving hibernation mode.
If the computer beeps but does not enter hibernation mode after pressing the sleep hot key, it means the operating system will not allow the computer to enter the power saving mode.
Do not change any devices (such as add memory or swap hard disks when the computer is in hibernation mode.
If the computer detects a PC I/O card installed in the PC card slots, the computer enters light green mode to maintain your communications connection. It will not enter standby nor hibernation mode.

BATTERY LOW
When the battery capacity is low and no adapter is plugged in, the system will generate the following battery low warning:
· · ·

If the AC adapter does not plug in within 3 minutes and the "Standby/Hibernation upon Batterylow" in BIOS SETUP is enabled, the system will enter Standby/0-Volt Hibernation Mode. The battery low warning will stop as soon as the AC adapter is plugged into the system.
THE AUTODIM PROCESS OF THE LCD BRIGHTNESS
The notebook has a unique "automatic dim" power saving feature. When the notebook is using AC power and you disconnect the AC adapter from the notebook, the system "decides" whether or not to automatically dim the LCD backlight to save power. If the LCD backlight is too bright, the system automatically adjusts it to a manageable level; otherwise, the level stays the same. If you want a brighter picture, you can then adjust the brightness and contrast level using hotkeys (Fn-F2). If you reconnect AC power to the system, the system automatically adjusts the LCD backlight to its original level -- the brightness and contrast level before disconnecting the AC adapter. If you adjusted the brightness and contrast level after disconnecting AC power, the level stays the same after you reconnect the AC adapter. There are two reasons for the notebook to have the LCD AutoDim feature. The first is to save the power during the notebook is operating under the DC mode. The second is to save the "favorite" brightness parameter set by the user.
1-22
Service Guide
The following processes are the basic methods used to implement the LCD brightness AutoDim. 1. 2. 3. 4. 5. If the original brightness is over 75% and the AC power is on-line, the BIOS will change the brightness to 75% after the AC power is off-line. If the original brightness is below 75%, the brightness maintains the same level even if the AC power is off-line. If the brightness is already changed by the hotkey under DC power, it will not be changed after the AC power is plugged in. If the brightness is not changed by the hotkey under DC power, the brightness will be changed back to the old setting -- the previous brightness parameter under AC power. If the previous brightness parameter does not exist, the brightness will not be changed in process 4.
