Hardware FAQ for A440
1.1 Question:
What are the available processors supported by A440?
Answer:
Currently, the supported processors are list as below,
- Intel Mobile Pentium III at 650//700/750/800/850MHz
- Intel Celeron 500/533/566/600/633/667MHz
We recommend the mobile processors which are tuned for optimal performance versus
lowest power in the notebook computing environment. Take note that the A440 support socket
370 FC-PGA packaging only!
1.2. Question:
The Brightness ( Fn+F8, F9 ) and contrast ( Fn+F10, F11 ) keys do not work?
Answer:
Usually, the brightness adjustment is so trivial that human eyes cannot tell the difference. It is
easier to see the changing of brightness in Windows environment rather than DOS
environment. Please also note that the contrast control keys ( Fn+F10, F11 ) do not work with
TFT but DSTN/HPA notebooks. For a better sense of brightness adjustment, please change
the background to white color if possible.
1.3 Question:
How to erase the password if the password is forgotten?
Answer:
You could adjust DIP SWITCH 5 to clear CMOS ( RTC ) data. The DIP SW5 position under
Memory socket door. You can use small flat screw driver to adjust position#4 switch to ON
and waiting for 3 to 5 minutes, then, please switch back to OFF position in the DIP SW3.
Warning!! Before clear CMOS ( RTC ) data, you must remove the AC adapter and Battery
first.
1.4. Question:
The battery life becomes shorter, How can I rebuild it ?
Answer:
Battery life will vary from user to user depending on how the computer is being used. To help
increase your battery life, you can configure the power management features within the
Power Management properties of Windows 98 Second Edition.
To access Power Management properties click on the Start button, go to Settings and choose
Control Panel. Next, click on the Power Management Icon. You can customize these settings
as you choose. You should be aware that any power management features will be of benefit
only if there are periods of inactivity which allow the settings to engage. Please note that the
battery in the A440 takes about 2.5 hours to fully charge with the machine turned OFF.
1.5 Question:
Why does a brand-new system have an empty battery?
Answer:
Due to the reason that the Ni-MH battery has self-discharged during shipping and shelf period.
Since the battery capacity is very low, it may take a few hours to prompt the battery voltage to
its normal stage. Please note the AC adapter LED will remain green even the battery is fully
recharged.
Also, the problem might be caused by BAD battery or drained battery. The drained battery is
caused by excessively self-discharge of Ni-MH battery. It will happen after the battery has
been stocked or shelved more than 3 months.
1.6 Question:
How do I do the battery learning cycle progress?
Answer:
Cycling your battery every month or so will extend the life expectancy of your A440 battery.
Important! Before beginning this process make sure your AC adapter is plugged in. The best
way to do this is to turn the unit ON and press the F2 key when prompted to enter Setup. Go
to the Power Management Setup menu and press Enter. Arrow down to Battery Auto
Calibration, and change it to enabled. By pressing the Pg Dn key, you will get a message
stating. “Please make sure that the AC adapter & battery are present. Do you wish to do
battery auto-learning? (Y/N)” Press Y and then Enter. Once calibration is completed the
computer will prompt you to shutdown and restart.
1.7 Question:
What is the function of PHDISK.EXE program and how to use it?
Answer:
The PHDISK utility of the notebook allows you to create a Suspend-To-Disk (STD) partition or
file that is used to save the opened files when you activate STD mode and power off the
computer. If you want to make use of the STD feature, you need first to run the PHDISK
utility.
You could see a message appear in a red column during Power On Self Test before you
execute the PHDISK.EXE. The red column displays ?Save To Disk file not found. Save to
Disk feature is disabled. Run Phdisk for information.
File: creat new. Partition: consult manual. Hit any key to exit. ?The above message will
disappear after you have execute the Phdisk.exe.
The Phdisk program has support FAT 16 and FAT 32 format also. To know the more detail
information about PHDISK, you could execute Phdisk /? on the command from the directory
where the PHDISK command is located.
1.8 Question:
How to adjust the CPU jumper switch setting?
You could find the string on the CPU surface , ex 700/256/100/1.65V, the 700 means CPU
frequency, 256 means cache size, 100 means external frequency, and in the last, the 1.65V
means core voltage.
The A440 could detects the CPU frequency automatically. For the CPU, you just need to
adjust the external frequency only. for your reference. ( Remove the heat sink plate then you
could see the S4 jumper, in the upper side of CPU socket. )
The S4 Jumper setting PIN1 PIN2 PIN3 PIN4
For 66 External Frequency ON OFF OFF OFF
For 100 External Frequency ON ON ON OFF
For 133 External Frequency OFF OFF ON OFF

1.9 Question:
What is an S-Video output?
Answer:
Super Video is a cable connection that produces sharper video images than standard
composite video cables. It accomplishes this by sending the video signal over the cable in two
channels one for color the other for brightness, rather than one.
Connect your S-Video cable to the television and the S-Video port on the computer. Set your
TV to the proper video input (refer to your TV’s documentation for instructions). Click on the
Settings tab. Click on the Advanced button. Click on the ATI Displays tab. Put a check in the
box next to Television. Click in OK to close the menu.
1.10 Question:

Power Saving Function key can not work.
1.11 Question:
How come of my Power saving Function key cannot work with windows 2000 environment?
Answer:
In the ACPI environment, Power Saving Function was controlled by OS and the Windows
2000 was an ACPI OS. That's why the Power Saving Function key can not work.
