Troubleshooting power management issues - Value Line notebooks

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:

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

    Click here to view the latest BIOS files for all Value Line notebooks.

  2. Adjust the power management settings according to your preferences and environment.
  3. Verify the health of the system battery.

    Notes:

    • 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.
  1. Disable any screen savers in the operating system.
    1. Right-click on the desktop background of the Microsoft operating system and then click Properties. The Display Properties window will be displayed.
    2. Click the Screen Saver tab.
    3. Select None from the pull-down list and then click OK.
  2. Disable any terminate and stay resident (TSR) applications.
    Notes:
    • These TSR applications may prevent some power management functions because they are constantly monitoring the computer.
    • Select the icon for an application from the system tray and click exit or disable from the menu.
  3. Scan all the files on the system with AntiVirus software using the vendor's latest virus definitions.

  4. Scan the system for spyware using the anti-spyware software's latest definitions. Perform a Web search for spyware software for more information.

  5. Verify the driver and firmware versions are the latest for attached hardware. This can be verified at the manufacturer's Web site, if available.
  6. Remove any attached hardware and device drivers. For testing purposes, temporarily disconnect any devices one at a time. Ensure all attached hardware is Advanced Power Management (APM) or Advanced Configuration and Power Interface (ACPI) compliant. This can be verified in the hardware device User's Guide from the manufacturer.
  7. Load the original or an earlier configuration.
    Save current settings using System Restore, then load the original or an earlier configuration. If you do not have either of these applications on your system, then continue to the next step.
    To open Microsoft Windows XP System Restore, click Start, select All Programs, select Accessories, select System Tools, and then click System Restore.
  8. Load the original configuration in the BIOS.

  9. If these steps have not solved your problem refer to "Need more help?"
