Power

AC Adapter
Battery
  • The battery pack is an internal power source to the computer when the AC adapter is not available. The battery pack is rechargeable and is charged using the AC adapter with the system.
  • You can determine how much battery power remains by using the Fuel-Gauge ThinkPad utility program. This displays the percent charge remaining, whether one or two batteries are in the system.
  • A 6-cell Li-Ion battery pack is shipped with the system.
  • Supports optional Slice battery as second battery at bottom.
  • Battery life:
    • 6-cell (48Whr): up to 6.0 hr
    • 6-cell (48Whr): up to 6.3 hr

  • Battery life (and recharge times) will vary based on many factors including screen brightness, applications, features, power management, battery conditioning and other customer preferences.

Security

System
  • Power-on password
  • Hard disk password
  • Supervisor password
  • Security keyhole
  • Fingerprint reader on selected models, offers users a convenient solution, authenticate at system startup and log on to Windows with a swipe of your finger.
Password
  • A Power-on password (POP) protects the system from unauthorized use. If a POP is set, the password prompt appears:
    • Each time the system is turned on
  • When the system is returned to normal operation from suspend mode
  • A Supervisor Password provides a higher level of security than the POP. The Supervisor Password protects the system functions from being used by unauthorized users,and protects the hardware configuration from unauthorized modification. The Supervisor Password prompt appears:
    • When the BIOS setup screen is accessed.
  • A Hard Drive Password (HDP) protects hard drive data from unauthorized users. Once HDP is set, data on the hard drive cannot be accessed without the correct HDP. Because the HDP is stored in the hard drive, the data remains protected even if the hard drive is removed to another system. The HDP password prompt appears:
    • Each time the system is turned on.

Repeated and frequent removal, for purposes other than to upgrade for greater capacity, can cause damage to the system. The Ultrabay Slim hard drive adapter is designed to provide this flexibility with a second hard drive in the Ultrabay Slim.
  • The Hard Drive Active Protection system protects your hard drive when the shock sensor inside your ThinkPad computer detects a situation that could potentially damage the hard drive.
