Why Does My Laptop Say Plugged In, Not Charging?

"Plugged in, not charging" means your laptop is running on wall power but the battery is not taking a charge. Common reasons are a built in charge limit or conservation mode, a weak or wrong charger, heat pausing the charge, a stalled battery driver, or an aging battery. It is often a setting or driver rather than a dead battery.

Why this happens

• A charge limit, battery conservation, or smart charging feature is holding the charge, often around 80 percent, to extend battery life.
• The charger is underpowered, damaged, or plugged into a port that does not deliver enough power.
• The battery is warm, and the laptop pauses charging to protect it.
• The battery driver has stalled and needs a refresh.
• The battery is old, worn, or failing.

Is this normal?

Sometimes. If a charge limit is set or the battery is already full, seeing not charging is normal. A battery stuck at a low percentage that never charges is not normal.

Does it cause any problems?

If it is a setting or driver, there is no harm and the laptop runs fine on AC power. If the battery is failing, you get much shorter runtime on battery and eventually need a replacement.

How to fix or check it

1. Check for a charge limit, conservation mode, or smart charging option in your laptop maker's app or in the BIOS, and disable it to test.
2. Confirm the charger wattage matches your laptop and, for USB-C, use a port that supports charging.
3. Inspect the cable, plug, and port for damage, and try a different outlet.
4. Let the laptop cool down, since heat pauses charging.
5. On Windows, open Device Manager, expand Batteries, uninstall Microsoft ACPI Compliant Control Method Battery, then restart to reinstall the driver.
6. Update the BIOS and any battery firmware from the maker.
7. Run powercfg /batteryreport in Command Prompt to check the battery's health and wear.
8. On a MacBook, open System Settings, Battery, Battery Health. Optimized Battery Charging may show Not Charging on purpose. On Intel Macs you can reset the SMC if it stays stuck.

Frequently asked questions

Why does charging stop at 80 percent?

That is a charge limit feature meant to extend battery lifespan. Disable it in your laptop maker's app or the BIOS if you want it to reach 100 percent.

Is my battery dead?

Check the battery report or health screen. A high cycle count with low remaining capacity means the battery is worn and should be replaced.

Can I keep using it on AC power?

Yes. The laptop runs normally on the charger even if the battery is not charging, though you have no runtime away from an outlet.
