Lithium-Ion Battery
Your Intel classmate PC - Convertible uses a Lithium-Ion battery pack that provides power when you don’t
have access to an AC outlet.
You must charge the battery pack for at least six hours before using it for the first
time. In the Standby Suspend mode, a fully charged battery loses its power in roughly 1/2 day or less. When not
being used, the battery
’s power will deplete in one to two months. The battery pack in this system is
replaceable by the end user.
Battery Low-Power Warning
1. Low Battery Warning
Low battery condition occurs when battery power is reduced to 10 percent. The red battery status LED
indicator blinks and the system beeps 3x in 1.2sec (each beeping last 200ms and 200ms off interval before the
next beep).
2. Very Low Battery Warning
Very Low battery condition occurs at 5 percent power remaining. The red battery status LED indicator blinks
and the system beeps 3x in 1.2sec (each beeping last 200ms and 200ms off interval before the next beep).
When the Intel classmate PC - Convertible 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 Intel classmate PC - Convertible 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 Intel classmate PC - Convertible is powered off.
It will take about 5 hours to charge the battery to 100% capacity while Intel classmate PC - Convertible is
powered on. When the battery is fully charged, the battery charge indicator becomes blue.
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 blue.
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 at room temperature. Higher temperature depletes 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.

The life expectancy of the battery is approximately 300 recharges.

See the notices section in the beginning of the user manual on how to care for the battery pack.

Use FF7 key to decrease the brightness of the screen.
