      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.
      • Universal AC adapter (72 W):
        • Input is 100/240V AC, 1.5/0.9A, 50/60Hz
        • Output is 16 V dc, 4.5A
      • 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, which displays the percent charge remaining.
      • A six cell Li-Ion battery pack is shipped with the system.
      • Approximate operation and charging hours are:
        • Power off/suspend charging:
          • 6-cell Li-Ion battery: 3.6 hours
        • Charging during operation:
          • 6-cell Li-Ion battery: 4.0 hours
        • Approximate hours of battery operation:
          • 6-cell Li-Ion battery: From 3.5 hours to 4.7 hours


      • (*1) Recharge time also varies.
      • (*2) These model numbers achieved eTesting Labs, Inc.'s BatteryMark 4.0.1 or the Ziff Davis Media Inc.'s Business Winstone 2002 BatteryMark Version 1.0 Battery Rundown Time of at least the times shown above. This test was performed without independent verification by VeriTest testing division of Lionbridge Technologies, Inc. ("VeriTest") nor Ziff Davis Media Inc.; neither Ziff Davis Media Inc. nor VeriTest makes any representations or warranties as to these test results. A description of the environment under which the test was performed is available at: www.ibm.com/pc/ww/thinkpad/batterylife.html. Battery life (and recharge times) will vary based on many factors including screen brightness, applications, features, power management, battery conditioning and other customer preferences.



      Locking device in the security slot provides physical security.

      • 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

      Operating system
      The following operating systems are supported on the ThinkPad R50e systems:
      • Microsoft Windows XP Professional
      • Microsoft Windows XP Home Edition

      Note: Previous versions of these operating systems are not supported.
