Low Battery Indication
When your notebook senses that the battery only has enough charge to continue
for a few minutes, it will alert you to a low battery condition by blinking red the
battery indicator and sounding a battery low warning beep. The remaining operating
time depends on the power you are consuming: if you are using the audio system,
PCMCIA slot or hard and floppy disk drives, your notebook might run out of charge
very quickly. You should always respond to the battery low indication by
connecting to AC power or turning off your notebook, or suspending your notebook
to disk. If you do not do so, the notebook will automatically suspend to disk
2
(regardless of the setting of the Suspend Mode option in the Setup Utility) and turn
off. The contents of the memory will be stored in the suspend-to-disk partition. You
will be unable to restart the notebook until you have connected to AC or installed a
fresh, charged battery.
If the notebook is in the Suspend to RAM mode when the battery is
critically low, the notebook will attempt to Suspend to Disk (if enabled
in the Setup Utility), and then turn off.
Maintaining the Battery Pack
You should discharge the battery pack if you do not use the notebook for a long time
and should recharge it fully before use. If the battery is fully charged and left unused
for a long time.
The battery will discharge itself slowly, and
The life of the battery will be shortened.
Lithium-ion batteries do not have so-called "memory effect,"and you do
not have to deep discharge the battery pack before charging it.
Disposing of Battery Packs
The capacity of a battery pack is gr
adually decreasing while used repeatedly. Although the deterioration rate depends
on the operating temperature and environments, the pack can sufficiently be used for
500 times, after which you should consider purchasing a replacement battery pack
that is identical to the battery pack.
Your local area may have rules which you should follow regarding battery disposal.
In addition to the main lithium-ion battery, you should remember the small backup
battery located under the keyboard. Bring your notebook to a local dealer for
replacement of this backup battery if your notebook begins to lose its time and date
setting.
Backup batteries
The notebook has two backup batteries. The rechargeable NiMH battery prevents
loss of data during replacement of the lithium-ion battery while in the suspend mode.
However, this will not work if the battery level of the NiMH battery is low. Therefore,
power-off or suspend to disk is recommended when replacing the lithium-ion battery.
The other backup battery is a non-rechargeable coin type Lithium battery for RTC.
