We recommend that you replace your battery when you notice a significant decrease of battery capacity. To change the battery pack, follow the steps below: 1. Close the lid and flip the computer over. Continue to hold it until the battery is removed. Make sure the replacement battery is properly oriented before inserting it into the battery compartment. Note: The battery can not be charged to 100% when remaining battery is no less than 95%. It is based on the supplier's advice, and to extend charging frequency and battery life. The AC adapter converts AC power to DC power and reduces the voltage supplied to the computer. It can automatically adjust to any voltage from 100 to 240 volts and outputs power at 12V, (12V, 3. 0A for X53SD), allowing you to use your Booktop X53SD computer in almost any region globally. CAUTION: Use only the AC adapter and the power cord we recommend. 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. 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. 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 Booktop X53SD and have the AC adapter connected whenever possible.
