Why is my Laptop Battery not charging even though it’s plugged in, displaying ‘plugged in, not charging’?

Instant fixes can sometimes assist as well. Try changing the power plan:

1. Open the Control Panel.
2. Select Power Options.
3. Change to a different power plan and then switch back to your preferred plan.

This minor adjustment can sometimes reset your laptop’s power management system and resolve the charging problem.

One common reason for this issue is a faulty power adapter. Check if the adapter is functioning correctly by testing it with another device or using a different adapter with your laptop. Sometimes, adapters can fail or the cords can become frayed, leading to inconsistent power delivery.

It’s also worthwhile to inspect the power port on your laptop. Dust, debris, or damage can prevent the laptop from charging properly:

1. Power off the laptop and unplug the charger.
2. Use a can of compressed air to gently blow into the power port and clear out any dust.
3. Visually inspect the port for any damage. If the port is loose or damaged, it may need professional repair.

Another angle to consider is firmware or software issues. Manufacturers occasionally release updates that can fix charging problems. Visit your laptop manufacturer’s website and search for firmware updates or specific patches addressing battery issues.

In addition to these steps, some users have found success by performing a power reset:

1. Shut down the laptop.
2. Unplug the power adapter and remove the battery (if possible).
3. Press and hold the power button for about 30 seconds to discharge any residual power.
4. Reinsert the battery and plug in the charger.

This method can resolve minor software bugs interfering with the battery charging process.

Occasionally, the problem might stem from outdated or corrupt battery drivers. Here’s what you can do:

1. Open Device Manager on your laptop.
2. Expand the Batteries category.
3. Right-click on ‘Microsoft ACPI-Compliant Control Method Battery’ and select ‘Uninstall device.’
4. Reboot your laptop. It should automatically reinstall the driver.

If the issue persists, check your power settings. Some power plans limit the battery charging to extend battery life. Go to your Control Panel, select Power Options, and ensure your settings are appropriate for full battery charging.

Another possible culprit is the battery itself. Over time, laptop batteries degrade and may no longer hold a charge effectively. Performing a battery health check can help you determine if it’s time to replace the battery. Most laptops come with built-in diagnostic tools accessible from the BIOS or through the manufacturer’s software. For instance:

1. Restart your laptop and enter the BIOS setup (usually by pressing a key like F2 or Del during startup).
2. Navigate to the battery health section and run a diagnostic test.

If you discover the battery health is poor, it may be necessary to purchase a replacement battery. Make sure to get one that’s compatible with your specific laptop model.

A less common, but possible issue could be related to the internal charging circuitry of the laptop. If none of the above solutions work, there may be a problem with the motherboard or specific charging circuits:

1. If you’re comfortable, you can open the laptop to inspect for any visual signs of damage.
2. Alternatively, take your laptop to a certified technician for a thorough inspection. They can conduct detailed diagnostics and potentially repair or replace faulty components.

Proper maintenance and periodic inspection of the laptop’s hardware can prevent future issues related to power and battery charging.
