Laptop is plugged in but not charging

“Plugged in, not charging” can mean insufficient charger power, the wrong USB-C port, a battery-protection limit, or a hardware problem.

Windows laptops • AC and USB-C chargingUpdated

Before you start

Save work and locate the charger supplied with the laptop. Check the manufacturer label for the required wattage.

Try these steps in order

Test after each step. If the problem is resolved, you can stop.

  1. Check the outlet and connection

    Connect directly to a known-working wall outlet. Reseat every detachable cable without forcing the connector.

  2. Use the correct charging port

    Some USB-C ports transfer data but do not charge. Look for the charging symbol or check the laptop manual.

  3. Compare the charger rating

    Use the original or manufacturer-approved charger with enough wattage. A phone charger may connect but still be too weak.

  4. Shut down and test

    Turn the laptop off and leave it connected for 20–30 minutes. Then start it and check whether the percentage increased.

  5. Check battery-protection settings

    A heart icon or charge limit near 50% or 80% may be intentional smart charging. Use the laptop maker’s app or documentation before changing it.

What your result may mean

The charger may be underpowered or the laptop may be using power faster than it receives it.
A different approved charger works
Stop using the original charger and ask the manufacturer about replacement.
