2.1 Battery Pack
Your Ultra Mobile PC is equipped with a high-energy rechargeable
Lithium Ion (Li-Ion) battery pack. Battery life will vary depending
on the product configuration, product model, applications loaded
on the product, power management settings of the product, and
the product features used by the customer. As with all batteries,
the maximum capacity of this battery will decrease with time and
usage.
2.2 Recharging The Battery Pack
Your Ultra Mobile PC supports both on-line and off-line recharge.
Follow the procedure below to recharge battery:
• Make sure the battery pack is installed in the Ultra Mobile PC.
• Connect the AC adapter to the Ultra Mobile PC and to an
electrical outlet.
When a battery pack is being recharged, its battery LED (located
at the bottom of LCD display) would be lit. For details on the LEDs,
please refer to Chapter 1.3. When the Ultra Mobile PC is OFF, a
depleted Li-Ion battery will take three hours to recharge.
2.3 Questions And Answers
I can feel a mild heat next to the battery pack. Is it normal?
The battery will generate heat during recharging and
discharging. There is a protection circuit inside the Ultra
Mobile PC to prevent overheating. User needs not to worry.
My battery operation time is not as long as it should be.
Why?
The battery is heat sensitive and can only be charged to its
maximum if the battery and its environmental temperature
remain within 15-25°C (59-77°F). The more the temperature
deviates from this range during recharging, the less chance
there is for the battery to be fully charged. In order to
recharge the pack to its full capacity, users are requested
to cool down the unit by unplugging the AC Adapter. Wait
until it is cooled down. Then plug in the AC Adapter to start
recharging again.
I did not use my spare battery for a few days. Even though
it was fully recharged, there wasn't as much power left as a
newly charged one. Why?
The batteries will self-discharge (1% per day for Li-Ion)
when they are not being recharged. To make sure a battery
pack is fully charged, recharge before use. Always keep the
battery inside the Ultra Mobile PC and have the AC adapter
connected whenever possible.
