Avoid the following finger conditions for enrollment or recognition as they might result in fingerprint enrollment errors or a drop in the fingerprint recognition success rate Soaked or swollen finger, for example as might occur after taking a bath. Injured finger Wet finger Soiled or oily finger Extremely dry skin condition on finger Observe the following to improve the fingerprint recognition success rate. Enroll two or more fingers. Enroll additional fingers if a recognition failure often occurs when using already enrolled fingers. Check the condition of your finger. Any conditions which have changed since enrollment, such as injury, rough skin, and extremely dry, wet, soiled, dirty, oily, soaked or swollen fingers, might lower the recognition success rate. Also if the fingerprint is worn down or the finger becomes thinner or fatter, the recognition success rate might be lowered. As the fingerprint for each finger is different and unique you should ensure that only the registered or enrolled fingerprint or fingerprints are used for identification. The fingerprint sensor compares and analyzes the unique characteristics in a fingerprint. However, there might be instances where certain users are unable to register their fingerprints due to insufficient unique characteristics in their fingerprints. The recognition success rate might differ from user to user. Battery This section explains battery types, use, recharging methods and handling. Battery types The computer has different types of batteries. Battery pack When the AC adaptor is not connected, the main power source of the computer is a removable lithium ion battery pack, also referred to in this manual as the main battery. You can purchase additional battery packs for extended use of the computer away from an AC power source although you should not change the battery pack while the AC adaptor is connected. Before you remove the battery pack, save your data and shut down the computer, or place the computer into Hibernation Mode. Be aware that, when placing the computer into Hibernation Mode, the contents of memory are saved to the internal storage drive, although for safety sake, it is best to also save your data manually.
