When the notebook warns you of its low battery condition, you will
have about three to five minutes to save your current work.
Do not expose battery packs to
temperatures below 0 degree Celsius (32 degree F) or above
60 degree C (140 degree F). This may adversely affect the
battery pack.
Charging the Battery and Charging Time
To charge the battery, plug the AC adapter into the notebook and
an electrical outlet.
For a totally discharged battery, it will take approximately two hours
to charge to 90% capacity, and approximately three hours to 100%
capacity while classmate PC is powered off. It will take about 5 hrs
to charge the battery to 100% capacity while classmate PC is
powered on.
When the battery is fully charged, the battery charge indicator
becomes green.
If system runs at heavy loads or in a high
temperature environment, the battery may not be fully
charged. You need to continue to charge it with the AC
adapter plugged in until the charging LED turns green.
System will not charge battery when
temperature exceeds 45
°C.
Checking the Battery Level
You can check the remaining battery power in Operating System
battery status indicator.
Prolonging the Battery’s Life and Usage Cycles
There are ways you can prolong the use of battery.
• Use the AC adapter wherever AC wall outlet is available. This
will ensure uninterrupted computing.
• Store the battery pack in room temperature. Higher
temperature tends to deplete the battery’s power faster.
• Make good use of the power management function. Save To
Disk (Hibernate) saves the most energy by storing current
system contents in a hard disk space reserved for this function.
