FastAccess Facial Recognition (Optional)
Your computer may have the FastAccess facial recognition feature. This feature helps keep your
Alienware computer secure by using the unique appearance of your face to verify your identity
and automatically supply login information that you would normally enter manually, such as
a user ID and password for a Windows account or a secure web site. For more information, click
Start
→ Programs→ FastAccess.
Battery Pack
Your laptop is equipped with a high‑energy rechargeable lithium ion prismatic (Li‑ion) battery
pack. Battery life will vary depending on your laptop configuration, model, applications
installed, power management settings, and features used. As with all batteries, the maximum
capacity of this battery will decrease with time and usage.
The battery meter lights on the battery pack indicate the charge level of the battery. When
you press the battery meter once, the charge level lights illuminate. Each of the five lights
represent approximately 20 percent of the total battery charge. For example, if four lights turn
on, there is approximately 60 to 80 percent of battery charge remaining and if no lights turn
on, there is no charge remaining in the battery.
