FAQ and troubleshooting
The chapter describes situations that you may encounter during
use of the Joybook Lite, along with basic troubleshooting steps.
If 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. When the amber light
of the battery indicator goes off, 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 goes off,
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.
