1 The battery status indicator (BATT) warns you when the battery is low. These durations are based
on the battery supplying the only power to the processor—power to the chassis is off—once the
status indicator first lights.
Follow these precautions to prevent the battery from
exploding. An exploding battery exposes toxic,
corrosive and flammable chemicals and causes burns.
• do not incinerate or expose the battery to high
temperatures
• do not solder the battery or leads
• do not open, puncture or crush the battery
• do not charge the battery
• do not short positive or negative terminals together
