NOTE: You, the customer, are solely responsible for data security. WinBook strongly recommends that you perform a backup of all personal data contained on your system prior to performing this procedure. Warning: WinBook will NOT be held responsible for any data loss incurred during this process.

Your WinBook notebook comes equipped with a durable, lightweight, rechargeable Lithium-Ion (Li-Ion) battery that can power your system for extended periods when fully charged. The actual duration of a charge will vary with how you use the computer and with how much you take advantage of the power management features of the system. In addition, you can obtain an additional battery that can be swapped into the battery bay of your WinBook notebook to provide even greater battery capacity.

The battery charges whenever the AC Adapter is connected to your system. The battery will charge whether the system is off, in the Hibernate mode, or operating. The fastest recharge occurs when the system is off or in hibernate mode. If the system temperature exceeds a safe level while the battery is charging, the system will stop the charging process in order to protect the battery. Once the battery temperature falls back within the safe range, the battery charging process will resume.

Each time you charge and partially discharge the battery, it stores slightly less power. After a while, it might only store about 80% of its potential charge. Similarly, if you do not use the battery for a few days, it will slowly self-discharge, and when it is recharged, it will hold less than 100% of the potential charge. To correct battery charge problems, you should allow the battery to fully discharge and then fully charge to help keep the battery in good condition. This operation carried out every few weeks will maintain the battery efficiency.

Over time, as the battery is charged and discharged, it gradually stores less energy. Li-Ion cells generally last for a few hundred or more cycles before they begin to deteriorate. You should replace your battery when you notice that it begins to store significantly less charge. If you replace the battery with a new one, you should first fully charge the battery so that the battery gauge in your WinBook notebook will be able to accurately measure the battery charge level.

Removing or Replacing the Battery

1. Make sure the notebook is turned off.

2. Unlock the battery using the Lock/Unlock button on the bottom of the notebook.

3. Locate the Battery Release button on the bottom of the notebook.

4. Gently move the Battery Release Button in the direction of arrow shown below the button.

5. While holding the Battery Release Button, slide the battery pack out of the battery compartment
