Charging and power modes

It takes up to 4 hours to charge the T100 tablet computer batteries from an empty state. It may take longer if you are using your device for power-intensive activities, for example using GNSS or processing a lot of data while you are charging it.

  1. Connect the appropriate international plug adapter for your region to the AC adapter.

  2. Connect the power cord to the charging port on the device.

  3. Plug the power supply into an electrical outlet.

You can check the battery level:

  • on the Lock screen. When you wake the device, the battery status appears in the lower-right corner of the Lock screen.

  • on the Desktop taskbar. The battery status appears on the right side of the taskbar. Tap the battery icon for information about the charging and battery status, including the charge percent remaining.

Two LEDs on the front of the tablet show the charging status:

Left LED

  • Green solid = device is booting, before the splash screen displays

  • Green flashing = device is in Sleep state

Right LED

  • Charger connected charging behavior

    • Amber solid = charging

    • Green solid = fully charged

  • Discharging behavior, based on the average capacity of both internal batteries

    • Off = battery above 10% State-of-charge, or <10% with system off

    • Red flashing = device is active (short flash) or in Sleep state (long flash). Battery charge < 10%

To check the current state of the battery charge when the device is off and no charger is connected, press the F1 key. The right LED will be lit for 4 seconds as follows:

  • Green if average capacity is > 80%

  • Amber if average capacity is between 20% and 80%

  • Red if average capacity is <= 20%

Solid red indicates that a battery has failed internally.

To turn on the device, push and quickly release the Power button.

Do not press the Power button repeatedly; do not hold the Power button for four seconds or longer.
