Low Battery Warnings
A battery’s indicator light
will begin blinking orange
to alert you to a “Battery
Low” status. Typically, this
is when the battery has
reached a charge level of
10% or less.
When there is only one
minute of battery charge remaining, the computer will suspend
its current state to the hard drive and power off. Plug in the AC
adapter and turn the computer back on to resume your work.
About Battery Usage
Over time, even with proper care, battery performance (the time
the battery can operate the computer before needing to be
recharged) will decrease. Depending on how often the battery
is used, how many times it has been charged and the conditions
under which it is used, you likely will need to purchase replace-
ment batteries during the life of your Tablet PC.
IMPORTANT: To avoid damage, only use TabletKiosk replacement
batteries. To prevent loss of data, do not remove both battery packs
at the same time while the system is powered on unless attached to
an external power source. Also, be sure to check the status of each
battery before removing it. If you remove a battery and the remaining
battery in the system does not retain a sufficient charge, the tablet
could power off unexpectedly.
NOTE: Do not dispose of batteries with household waste. When a
battery can no longer hold a sufficient charge, call your local waste
disposal or environmental protection agency for advice on how or
where to dispose a lithium-ion battery.
Real Time Clock Battery
In order to maintain certain system information while the power
is off, the motherboard contains a small built-in battery pack that
constantly supplies power to the system.
