Power
AC Adapter
  • AC adapter: This ac-to-dc converter supplies the necessary power to the computer. The ac adapter also charges the battery pack when it is installed in the computer.
  • Battery (Click here for more information)
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- or 9-cell Li-Ion battery pack is shipped with the system.
  • Supports optional Slice battery as second battery at bottom.
  • Battery life: 3-cell:
    • MobileMark® 2007: Windows 7: up to 9.0 hr
    • MobileMark 2012: Windows 7: up to 5.9 hr, Windows 8: up to 6.4 hr

Notes:

  • 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
  • Security chip
  • 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.

Software
Operating system
  • Windows® 7 Professional (64-bit)
  • Windows® 8 Pro (64-bit)
