Troubleshooting
Symptom
Possible Fault
Action
Indicator does not
switch on, or switches
off during the boot
process, or battery is
not charging.
Battery deep
discharged
If the red stable LED turns on when the power adaptor is plugged in, then leave
it on charge for 30 minutes to see if the battery will recover and allow the
indicator to turn on. If the red stable LED does not turn on when the power
adaptor is plugged in, or if the battery does not recover after 30 minutes of
charging, then check the battery voltage and if less than 2.5 V, replace the
battery (see page 27).

Do not short-circuit the battery as it can deliver a peak current in
excess of 100 A and possibly overheat.
