Is it a software-related issue? If a replaced battery does not solve your problem, the next laptop battery troubleshooting tip is to explore the possibility that the software is malfunctioning. If the battery status is not being displayed correctly, the software could be causing the problem rather than the battery.

Is there a “hiccup” in the system? To power reset the system, or ensure that the motherboard is denied all power, unplug the machine and remove the battery. Hold down the power button for a full minute. Next, reattach the battery and AC adapter and attempt to restart the computer again.

Does the laptop need to be recalibrated? When a new battery is installed, it may fail to charge to a full 100% anymore. If your battery stops charging itself at about 97%, you need this laptop battery troubleshooting tip. Begin the recalibration process by preventing the computer from going to sleep when the battery is low. If your operating system is XP, go to the Control Panel > Performance and Maintenance > Power Options and set the power scheme to “Always On.”

  • Where it says “Alarms,” uncheck the boxes by “Critical battery alarm” and “Low battery alarm.”
  • Where it says “Hibernate,” uncheck the box by “Enable hibernation.”
  • When finished, click “Apply.”

Now the computer can fully drain the battery and when you charge it again, it should reach 100%. It may take two or three times to completely reach 100%.
