FAQ and troubleshooting

The chapter describes situations that you may encounter during

you are not able to resolve the issue, contact a nearest BenQ
service center for assistance immediately.

Battery and power

How long should I charge the battery for the first time?
The length of the charging time may vary. 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 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
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
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.
When the battery icon in the notification area on your Joybook
shows the battery is fully charged, it means that the battery has
reached a saturated voltage: 95%~99%. At this moment, the
voltage difference detected by your Joybook 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.
How come my notebook is not fully charged even after a full
night charge?
Make sure the Joybook is receiving power. Is the power cord
plugged in correctly? If the battery is installed in the Joybook
and it is properly connected to an AC outlet, check if the battery
meter icon is showing a charge sign. If this does not fix the
problem, then the battery, the power source in your Joybook, or
the AC power cord may be defective. Consult your BenQ dealer
for help and maintenance.
