Troubleshooting power management issues - ThinkPad

Some of these steps may not apply to your computer. Test the system under normal operating conditions to verify the power management settings after performing each step:

Battery drains more quickly than expected

  1. Verify that the latest BIOS and Embedded Controller when available for the ThinkPad system have been installed.
    Note: Not all ThinkPad systems require a separate Embedded Controller utility.

  2. Adjust the power management settings according to your preferences and environment.
    • Windows XP  Click Start -> Programs ->  ThinkVantage -> ThinkVantage Power Manager
    • Windows 7  Same as XP or go to Control Panel -> Lenovo-Power Controls
    1. Verify the health of the system battery.
      1. Click the Battery Gauge Icon Battery MaxiMiser Guage icon on the taskbar and then click Launch Power Manager.... The Power Scheme window will appear.
        Note: The screenshots and steps outlined may be different depending on the version you are running of Battery Maximiser or Power Manager.

      Notes:

      • Status of the battery:
        • Green means good condition
        • Red means the battery needs to be replaced. ThinkPad system batteries typically have a maximum warranty of one year.
          Note: If your battery needs to be replaced, then see the Need more help? section below to contact the Support Center or buy a replacement.
      • Remaining time is calculated based on the current remaining capacity divided by the average current battery consumption (wattage). Depending on the current battery wattage consumption, remaining time calculated can change. For example, with the system running at the Maximum Performance setting for the processor, the system consumes more battery power, so the remaining time is shorter. A good analogy would be driving a car. When you drive faster, you use more gasoline; slower uses less. If you speed up and slow down frequently, it is more difficult to estimate how much driving time you have left.
      • The Power scheme settings can also be adjusted to improve battery life and performance.
