SECTION 1
Low Battery State
Here is the explanation on the indication when the battery of this PC enters in low battery
status and the countermeasure against it.
Low Battery Status Indication
The remaining battery power indicator blinks in the status indicator LCD.
Counter measure against Low Battery Status
1 Connect the AC adapter.
The battery is charged with the connection of the AC adapter.
Critical Point
Alarm sounds when the unit with Windows NT becomes low battery state. However, this
alarm may not be audible if sound volume level is set low.
Alarm sound is not audible if speaker is turned off.
Speaker is turned On/Off by pushing the [F3] key while pressing down the [Fn] key. A sound
like whistle means that the speaker is turned on and silence means that it is turned off.
Critical Point
If you continue operating the PC under the low battery status, data might be lost during your
operation while creating or saving it in the worst case. Connect the AC adapter immediately.
And if the AC adapter is not available, save the working data, close the applications in use
and turn off the power of the PC.
The read and write function to the hard disk consumes a lot of power. Use the AC adapter to
save data to the hard disk under low battery status.
If you leave the PC unit under low battery status, it enters suspended status automatically.
However, the unit will not be suspended before the completion of the data read and write
function to hard disk.
Windows XP is preset to enter standby mode automatically when the remaining battery level
becomes low. Do not change the settings in the following items under Power Options Properties.
Low battery alarm:
• Activate low battery alarm when power level reaches 10% is default setting. Under Alarm
Action you can set the setting of low battery alarm actions.
Critical battery alarm:
• Activate critical battery alarm when power level reaches 3% is default setting. Under Alarm
Action you can set the setting of critical battery alarm actions.
If you use your computer with these items unchecked ( ), the power will be immediately shut
down when the battery becomes dead and unsaved data will be lost. It could also lead to a
system failure.
Windows 2000 and Windows 98 / Windows Me automatically suspend the PC when the
remaining battery power lowers to 3%. Do not change the following settings in the Alarm tab
in the Power Option Properties dialog box:
• “Activate critical battery alarm when power level reaches”
• The following items in “ Low battery alarm “ dialog box that appears with the click on “Alarm
action”.
• “When the alarm goes off, the computer will” in “Stand by”
• “Force standby or shutdown even if a program stops responding”
If those items are checked by clicking, the power is on until the battery is completely ex-
hausted and the working data will not be saved. And this might result in the machine failure of
the PC unit.
