Battery and power

How long should I charge the battery for the first time?
The length of the charging time may vary. When the blue light
of the battery indicator is on, it means that the battery is fully
charged.
Alternatively, check the battery icon in the notification area
located in the lower right corner of the desktop to see if the
battery is fully charged.
My Joybook Lite won't start up with the battery inserted. What
should I do?
• Make sure the battery is properly inserted.
• Make sure the battery is fully charged. If this does not work,
consult your BenQ dealer.
What should I do with the battery if I will not use my Joybook
Lite for a long time?
Recharge the battery or discharge it to about 40% full, and then
store it in a dry place at about 15°C to 25°C. Extremely high or
low temperature will shorten the battery life.
The battery icon in the notification area on my Joybook Lite
suggests that the battery is fully charged. However, when I check
it from the Power Manager in Windows, the battery level is only
about 95%-99%. Why?
It is the result of the battery protection design of your Joybook
Lite. When the battery indicator on your Joybook Lite lights up
in blue, it means that the battery has reached a saturated
voltage: 95%~99%. At this moment, the voltage difference
detected by your Joybook Lite is very small, so it will reduce the
charging current to prevent overcharging the battery with excess
current or voltage, which will damage the battery. Moreover, in
order to protect the battery from exposing to high voltage and
current for a long time during charging, the battery has been
equipped with a protection circuit that will charge the battery at
low current in the final phase.
