I did not use my spare battery for months. I have problem in
recharging it.
If you happen to leave your battery pack to go through an
extended period of self-discharge, say more than three
months, the battery voltage level will become too low and
needs to be
Pre-Charged
(to bring the battery voltage level
high enough) before it automatically (for Li-Ion only) resumes
its normal
Fast
Charge
.
Pre-Charge
may take 30 minutes.
Fast
Charge
usually takes 2~3 hours.
2.4 Battery Maintenance
To maintain the battery pack's maximum capacity, you should
occasionally let the
Ultra Mobile PC
deplete its battery power
completely before recharging.
To carry out a complete depletion of the battery, disconnect the
AC adapter and let your
Ultra Mobile PC
consume the remaining
battery power. To speed up the depletion, use the HDD as much as
possible. When the battery is empty, wait for the
Ultra Mobile PC
to cool down (especially the battery). The temperature should be
within 15-25°C (59-77°F). Then insert the AC adapter to recharge
the battery.
2.5 Power Consumption
The
Windows™
operating system has incorporated the latest
state-of-the-art
ACPI (Advanced Configuration Power Interface)
power management methodology. In order to fully utilize the
power of your battery packs, it would be a good idea for you to
spend sometime to acquire a basic understanding of the power
management concept from your operating system.
In
Windows™
Operating
Systems
, you can go through
Power
Options
of the
Control
Panel
according to the version of
Windows™
Operating
System
the
Ultra Mobile PC
applies. We
shall not describe them in details.
2.6 Reducing Power Consumption
Although your
Ultra Mobile PC
(together with the operating
system) is capable of power conservation, there are measures you
can take to reduce the power consumption:
•
Use the AC power whenever possible.
•
Try to use the HDD drive to read and write files, instead of
using the external USB FDD.
•
Disable unused devices, such as Web Cam, WLAN, Bluetooth
®
,
and etc.
•
Decrease LCD panel brightness through Windows.
Note:
Whenever system is powered on or powered off, make sure
the battery pack is installed in the battery pack compartment.
