2.1 Battery Pack
Your M1028 CafeBook 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 M1028 CafeBook supports both on-line and off-line recharge. Follow the procedure below to
recharge battery:
*Make sure the battery pack is installed in the M1028 CafeBook.
*Connect the AC adapter to the M1028 CafeBook and to an electrical outlet.
When a battery pack is being recharged, its battery LED (located at the upper left corner of LCD
display) would be lit. For details on the LEDs, please refer to Chapter 1.3. When the M1028
CafeBook is OFF, a depleted Li-Ion battery will take three hours to recharge.
2.3 Questions And Answers
Q: I can feel a mild heat next to the battery pack. Is it normal?
A :The battery will generate heat during recharging and discharging. There is a protection circuit
inside the M1028 CafeBook to prevent overheating. User needs not to worry.
Q:My battery operation time is not as long as it should be. Why?
A: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.
Q: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?
A:The batteries will self-discharge when they are not being recharged. To make sure a battery pack
is fully charged, recharge before use. Always keep the battery inside the M1028 CafeBook and
have the AC adapter connected whenever possible.
Q:I did not use my spare battery for months. I have problem in recharging it.
A: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.
