Hardware Setup

Inserting the Main Battery

Press the Power key after the battery is inserted into the MX7.
Note:
The MX7 Battery Compartment is located at the bottom of the back of the computer. The battery
case serves as the back cover for the battery well for the MX7.
Place the battery in the battery well, making sure the tab on the bottom of the battery pack fits into
the slot at the bottom end of the battery well. Push the battery down into the battery well until the
tab clicks into place and the battery pack is secure in the battery well.
The backup battery is trickle-charged by the main battery. Whenever possible, use the AC power
adapter with the MX7 to conserve the main battery and charge the backup battery.
The Status LED indicates battery condition. It is steady red when the main battery is Low. When
the battery has sufficient energy the Status LED is unlit. The Battery control panel displays main
and backup battery charging and power status (Start | Settings | Control Panel | Battery).

About Lithium-Ion Batteries

Li-Ion batteries (like all batteries) gradually lose their capacity over time (in a linear fashion) and
never just stop working. This is important to remember – the MX7 is always 'on' even when in
the Suspend state and draws power from the batteries at all times. Tap the
Panel | Power tab to check the battery status and power reading.
The following chart is an approximation. Actual battery capacity varies based on usage, ambient
temperature and peripherals drawing power from the MX7:
Deciding when to put a fully charged main battery pack in the MX7 is difficult to quantify
because it is very application specific. 1800 mAh may be the cutoff for one customer who uses the
mobile device frequently, while 1000 mAh may be perfectly fine for a customer who occasionally
uses the mobile device. You need to determine the point at which battery life becomes
unacceptable for your business practices and replace the main battery pack before that point.
Note:

On first use the MX7 batteries should be charged with an external power source (i.e. AC
Adapter) – 3.5 hours for the main battery and 7 hours for the backup battery. New main
battery packs alone must be charged prior to first use – this process takes up to four
hours in an LXE Multi-Charger.

The battery should not be replaced in a dirty, harsh or hazardous environment. When the
battery is out of the MX7, any dust or moisture that enters the battery compartment can
get into the main unit, potentially causing damage.
