pack, and it takes approximately 4 hours to charge it to full from the power adaptor (for
the first time charging the main battery, please charge it for at least 8 to 12 hours).
However, the charging time may vary by your working condition.

suspension when the main battery is depleted. The backup battery is a 3.7V, 90mAh
rechargeable Li-Polymer battery, and can retain data in the DRAM for 5 minutes when it is
fully charged (as long as wireless modules on the mobile computer are inactive).
It also keeps Wi-Fi and Bluetooth connections for about 30 seconds in suspend mode after
the main battery is removed. The Wi-Fi and Bluetooth connections will resume right after
the main battery is installed within the time period the connection is retained.
The backup battery can be charged by the main battery or the power adapter, and takes
