Checking the Battery Gauge
Battery life is largely affected by the user’s usage habits. The battery may need up to twelve hours
to charge completely.
Checking Battery Gauge
[Start] > [Settings] > [Power] > [Battery]
Low Power Warning
If the remaining battery charge cannot support the running system any more, a low power warning
message window will appear on the screen. You will need to press the <Power> button to turn off
the power, and charge the battery as soon as possible.
Backup Battery
The backup battery can safely maintain the RAM data, even when the main battery is discharged
completely.
Disposal of Battery
If the battery becomes damaged or reaches its end-of-life, you need to purchase a new one.
Please dispose the used batteries in an approved location.
Caution:
If the main battery and the backup battery are both discharged, the RAM data will be
lost. Any unsaved data in the running programs will be lost. After charging and
rebooting, the system will not be restored to its previous state.
