Laptop Battery Not Charging

First separate charger power from a charging-status problem

Stop before testing if the battery is swollen, overheating, leaking, or physically damaged. Shut down, disconnect the charger if safe, and discontinue use. Do not keep running on AC power, press a raised case flat, open the battery pack, or try to puncture it. Arrange manufacturer or qualified repair support.

This page starts with a laptop that gains no charge or does not reliably recognize its power source. If Windows consistently recognizes AC power but the percentage stays at a limit, follow plugged in but not charging for the charging-policy checks.

1. Save your work and inspect without bending the connector. Try a working wall outlet and reconnect an undamaged adapter firmly. Intermittent charging when the plug moves suggests a cable or port fault; stop wiggling it as a workaround.
2. Match the entire power path. Use the laptop manufacturer's supported adapter specification. With USB-C, the port must accept charging and the cable and adapter must support the required power delivery. Bypass a dock and disconnect other devices from a shared charger for the test.
3. Compare idle and powered-off charging. With a cool, undamaged laptop, note the percentage, shut down normally, and leave the supported charger connected for 20–30 minutes. A rise only while off suggests incoming power cannot keep up with use, rather than proving battery failure.
4. Change one component at a time. A known-good compatible charger working where the original fails isolates the adapter/cable path. Failure with both needs model-specific diagnostics; it does not prove the battery alone is bad.

If Windows says no battery is present, use battery detection checks. Do not attempt a BIOS update while charging or power is unstable; firmware work requires the manufacturer's prerequisites and reliable power.

That message often appears when the laptop detects power but chooses not to charge normally. Some models pause charging because of battery protection limits, some react to weak or incorrect chargers, and others show it because Windows or the battery controller needs to refresh.

It can also happen when the battery is badly worn and no longer responds normally to charging.

1. Restart the laptop. This clears temporary charging logic or driver glitches.
2. Check the battery percentage carefully. Some laptops stop charging on purpose around 80% to reduce wear.
3. Shut down and reconnect power. Fully power off the laptop, unplug the charger, reconnect it, and start again.
4. Watch for flickering charging status. If the icon changes repeatedly, the cable, adapter, or port may be loose.

• Make sure you are using the correct charger wattage for the laptop
• Check the charging cable for fraying, kinks, or a loose connector
• Try another wall outlet
• If possible, test with a known-good charger
• If the USB-C charging cable feels weak or generic, try a higher-quality supported one

If charging works again with another adapter, the battery may be fine and the charger was the real problem.

1. Open Device Manager.
2. Expand Batteries.
3. Right-click Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery.
4. With stable AC power, uninstall only the identified battery entries. Keep any option to remove the driver package unchecked. Follow your model's support instructions; restart so Windows can redetect them.
5. Restart the laptop.

This is a common Windows-side fix when the charging status is wrong but the hardware is still fine.

Check whether your laptop maker has battery health or conservation mode enabled. Some systems intentionally stop charging at 60% or 80% to reduce wear, which can look like a fault if you do not know the setting is turned on.

If the laptop also has short runtime, use the Battery Health Check Laptop tool and the battery report guide to see whether the battery itself is already worn out.

Some charging problems come from firmware behavior rather than Windows alone. If your laptop maker has a BIOS or power management update specifically related to charging or battery behavior, it may be worth reviewing after basic checks.

This is more important when the problem started right after an update, a battery replacement, or a long period of not using the laptop.

• The charging port feels loose or only works at certain angles
• The adapter is known good, but the laptop still will not charge
• The battery report shows very poor health or severe wear
• The battery is swollen or the case looks warped
• The laptop runs very hot while trying to charge

If heat is involved too, check the Laptop Overheating Fix guide. If the main goal is reducing wear after you solve charging, the Improve Laptop Battery Life guide is the right next step.

If Windows stops seeing the battery completely instead of just failing to charge it, the next page to read is Battery Not Detected on Laptop.
