At least once a month, disconnect the tablet from a power source and
operate it on battery power until the battery pack fully discharges.
Before doing so, follow the steps as detailed below.
1. Turn off the tablet's power.
2. Disconnect the AC adaptor and turn on the tablet's power - if it does
not turn on then go to Step 4.
3. Operate the tablet on battery power for five minutes. If you find that
the battery pack has at least five minutes of operating time, continue
operating until the battery pack is fully discharged, however, if the
Battery indicator flashes or there is some other warning to indicate a
low battery condition, go to Step 4.
4. Connect the AC adaptor to the DC IN 19V jack of the tablet, and to
a wall outlet that is supplying power. The DC IN indicator should glow
green, and the Battery indicator should glow amber to indicate that the
battery pack is being charged, however, in the event that DC IN
indicator does not glow this indicates that power is not being supplied -
check the connections for the AC adaptor and the power cord.
5. Charge the battery pack until the Battery indicator glows green.
Power-up modes
The tablet has three different power-up modes as follows:
Shut Down Mode: The tablet will shut down without saving data - in
view of this you must always save your work before you turn the tablet
off.
Hibernation Mode: Data in memory will be saved to the Solid State
Drive.
Sleep Mode: Data will be maintained in the tablet's memory.
Please refer to the sections Turning on the power and Turning off the
power in Chapter 1, Getting Started for further information.
