Understanding the Problem:

The "Lenovo battery not detected" error usually manifests as:

• Battery icon missing or showing "0% charged".
• Laptop running solely on AC power, unable to operate on battery.
• System messages indicating "Battery not detected" or "Battery not installed".

Troubleshooting Steps:

1. Check the Basics:

• Verify the Battery is Installed: This may seem obvious, but double-check that the battery is properly inserted and secured in its compartment.
• Ensure Power Connection: Make sure the AC adapter is securely connected to the laptop and the power outlet.

2. Update or Reinstall Battery Drivers:

• GitHub Insights: A common thread on GitHub revolves around outdated or corrupted battery drivers being the culprit.
• Solution: Go to Lenovo's support website and download the latest drivers for your specific laptop model. Uninstall the existing drivers and install the new ones.

3. Run Battery Calibration:

• GitHub Insights: Users on GitHub have reported success with calibrating the battery to reset its charge cycle and improve its performance.
• Solution: Locate the "Battery Calibration" tool in your Lenovo settings or search for it online. This tool will typically discharge and fully charge the battery, allowing the system to accurately measure its capacity.

4. Check BIOS Settings:

• GitHub Insights: Some users have found that disabling the "Fast Startup" feature in the BIOS resolved the issue.
