“Plugged in, not charging” shows up under the battery icon in Windows 11 even though the charger is connected and the laptop is on. That’s confusing, but most of the time the battery itself is fine. The real problem is usually a loose connection, a stale driver, or a battery-health feature capping the charge on purpose.
Quick Diagnosis
Before trying any fix, open Settings > System > Power & battery. Check the exact status text next to the battery icon. “Plugged in, not charging” means Windows sees the AC adapter but the battery won’t accept a charge. A frozen percentage like 60% or 80% is different; that’s usually a manufacturer charge-limit feature, not a fault. Note which one you see. It decides whether you start with the physical checks below or jump straight to your brand’s battery utility.
Fix #1: Check the Physical Connection
A loose cable or weak outlet causes more “not charging” reports than any driver bug. Start here before you touch Device Manager.
- Unplug the charger from both the laptop and the wall, then reconnect each end firmly.
- Inspect the cable and connector for frayed wiring, bent pins, or a wobbly USB-C tip.
- Try a different wall outlet. If you’re plugged into a power strip or a UPS (uninterruptible power supply), plug directly into the wall instead to rule out a dead outlet.
- If you charge through a docking station or USB-C hub, unplug it and connect the AC adapter directly to the laptop’s charging port.
- Confirm you’re using the correct adapter wattage. A 45W charger won’t fully charge a laptop that needs 65W or 90W. It may show “connected” but never raise the battery level. That’s common on USB-C laptops that negotiate power delivery.
- Try a different port if your laptop has more than one USB-C charging port.
If the laptop charges normally after any of these swaps, the problem was hardware-adjacent, not Windows. Replace the damaged cable or underpowered adapter and you’re done.
Fix #2: Reinstall the Battery Driver
Windows manages battery charging through a generic driver. That driver occasionally gets corrupted after sleep, a Windows update, or a BIOS change.
- Right-click the Start button and select Device Manager.
- Expand the Batteries category.
- Right-click Microsoft ACPI-Compliant Control Method Battery and select Uninstall device.
- Confirm the uninstall if prompted. Don’t uninstall Microsoft AC Adapter yet; do it one driver at a time.
- Unplug the AC adapter, wait 10 seconds, then plug it back in.
- Restart the laptop. Windows automatically reinstalls the battery driver on boot.
- If the issue persists, repeat the same steps for Microsoft AC Adapter, listed under the same Batteries category or under Batteries and System devices depending on your model.
Check Settings > System > Power & battery again after the restart to confirm the status text now says “Charging.”
Fix #3: Run the Windows Power Troubleshooter
Windows 11 ships with an automated tool that scans for common power-management problems. That includes corrupted power schemes that block charging reports.
- Open Settings > System > Troubleshoot > Other troubleshooters.
- Scroll to find Power and click Run.
- Follow any prompts the troubleshooter gives you and apply the recommended fixes.
- Restart the laptop once it finishes, even if it reports no issues found.
This fix resolves cases where Windows misreports charging status even though the hardware works fine.
Fix #4: Check the BIOS Battery Charge Threshold
Dell, ASUS, and some Lenovo models let you set a maximum charge limit directly in BIOS/UEFI firmware, separate from any Windows app. If this threshold is set low, “not charging” simply means the battery already reached its limit.
- Restart the laptop and press the BIOS entry key repeatedly during boot, commonly
F2on Dell and ASUS, orF1/EnterthenF1on Lenovo, andEscthenF10on HP. - Look for a section named Power, Battery, or Charging Configuration.
- Check for a setting like Custom Charge, Primary Battery Charge Configuration, or Battery Health Charging and note the current threshold.
- Set it to Standard, Adaptive, or Full Capacity temporarily to test whether the battery starts charging past the limit.
- Save changes and exit, usually
F10.
If raising the threshold fixes it, the laptop was working exactly as configured. You can leave it on a lower threshold like 80% for long-term battery health, or set it back to full capacity if you need maximum runtime.
Fix #5: Adjust Battery Settings in Dell Power Manager
Dell laptops manage charge limits through Dell Power Manager rather than relying solely on BIOS.
- Open Dell Power Manager from the Start menu, or download it from Dell’s support site if it’s not installed.
- Go to the Battery Information or Battery Settings tab.
- Check whether Primary Battery Charge Configuration is set to Adaptive, Express Charge, Standard, or Custom.
- If it’s set to Custom with a low stop percentage, switch it to Adaptive or raise the custom limit.
- Apply the change and unplug/replug the charger to trigger a fresh charge cycle.
Fix #6: Run HP Support Assistant Battery Diagnostics
HP laptops use Battery Health Manager, controlled through the HP Support Assistant or HP App, to cap charging for long-term battery preservation.
- Open HP Support Assistant (or the HP App on newer machines) from the Start menu.
- Go to Diagnose & Fix or the My Devices section.
- Run the built-in Battery Check or Hardware Diagnostics scan.
- If the scan reports a healthy battery but limited charging, check Power Settings or Battery Health Manager for a charge mode set to Best for Battery Health. This typically caps charging around 80%.
- Switch it to Balanced or Best for Battery Performance if you need a full charge, then test again.
Fix #7: Check Lenovo Vantage Conservation Mode / Smart Charging
If a Lenovo battery seems stuck around 55–60%, Conservation Mode is almost always the reason. It’s easy to mistake for a hardware fault the first time you see it.
- Open Lenovo Vantage from the Start menu.
- Go to Device > Power (or Hardware Settings on older versions).
- Check whether Conservation Mode is toggled on. If so, turn it off to allow charging to 100%.
- Alternatively, check Smart Charging, which adjusts charge speed and limits based on usage patterns rather than a hard cap.
- Close Lenovo Vantage and confirm charging resumes in Settings > System > Power & battery.
Fix #8: Check ASUS Battery Health Charging in MyASUS
ASUS laptops use Battery Health Charging modes inside the MyASUS app to balance battery longevity against runtime.
- Open MyASUS from the Start menu.
- Go to Customization > Battery Health Charging.
- Check whether the mode is set to Balanced (80% cap) or Maximum Lifespan (60% cap).
- Switch to Full Capacity to test whether the battery charges past the previous limit.
- While you’re in MyASUS, run System Diagnosis > Diagnostic Tool > Battery problems Checkup to rule out a hardware fault at the same time.
Fix #9: Check Battery Health With powercfg
If none of the above explain the behavior, the battery itself may have degraded. Windows can generate a report comparing original capacity to current capacity, which is the closest thing to an X-ray you’ll get without opening the case.
- Open the Start menu, type
cmd, and open Command Prompt (or Windows Terminal). - Run the following command:
powercfg /batteryreport- Note the file path printed in the output; it’s usually your user folder.
- Open the generated
battery-report.htmlfile in your browser. - Compare Design Capacity to Full Charge Capacity in the report.
A Full Charge Capacity that’s 20–30% lower than Design Capacity is normal wear after a few years. A larger gap points to a battery that needs replacing, not a software fix. So does a capacity that keeps dropping each time you run the report.

Signs It’s a Hardware Failure
Stop troubleshooting software and contact the manufacturer if you notice any of the following:
- The battery is visibly swollen, or the trackpad/keyboard bulges outward.
- The laptop only turns on while plugged in and shuts off instantly when unplugged, even at “100%.”
- No charging LED lights up on any outlet, cable, or adapter combination, including a known-working spare adapter.
powercfg /batteryreportshows Full Charge Capacity dropping noticeably between reports taken weeks apart.- The battery isn’t detected in Windows or BIOS at all, even after a full 24-hour trickle charge with the laptop powered off.
A swollen battery is a safety hazard. Stop using it immediately, and don’t try to charge or puncture it. Contact Dell, HP, Lenovo, or ASUS support, or an authorized repair center, for a replacement instead of fixing it yourself.
Getting Help
If you’re still stuck after working through these fixes:
- Check Event Viewer > Windows Logs > System for Kernel-Power or battery-related errors around the time charging fails.
- Dell, HP, Lenovo, and ASUS all offer free chat and phone support for battery diagnostics, especially useful if the laptop is still under warranty.
- Third-party tools like BatteryInfoView can supplement
powercfg /batteryreportwith live cycle-count data if you want a second opinion before requesting a replacement.
Prevention Tips
- Use the original or a certified adapter: A mismatched wattage USB-C charger is one of the most common causes of intermittent “not charging” errors.
- Keep OEM battery software updated: Dell Power Manager, HP Support Assistant, Lenovo Vantage, and MyASUS all push firmware and driver fixes that affect charging behavior.
- Set a sensible charge limit, not none at all: An 80% cap through your brand’s utility extends battery lifespan far more than charging to 100% every day.
- Keep vents clear: Overheating triggers safety cutoffs that look identical to a charging fault.
Frequently Asked Questions
Why does my laptop say “plugged in, not charging” in Windows 11?
Usually it’s a corrupted battery driver, a loose cable/port connection, or an underpowered charger. Reinstalling the battery driver (Fix #2) resolves most cases that aren’t physical connection problems.
Why is my battery stuck at 60% or 80% and not charging further?
Your brand’s battery-health feature is capping the charge on purpose to slow long-term wear. That includes Lenovo Conservation Mode, HP Battery Health Manager, and ASUS Battery Health Charging. Check the relevant brand utility (Fixes #6–#8) to confirm and adjust it.
How do I reinstall my battery driver in Windows 11?
Open Device Manager, expand Batteries, right-click Microsoft ACPI-Compliant Control Method Battery, and choose Uninstall device. Restart, and Windows reinstalls it automatically. See Fix #2 for the full steps.
How do I check BIOS battery charge settings on my Dell/HP/Lenovo/ASUS laptop?
Restart and enter BIOS with the model-specific key: F2 on Dell/ASUS, Esc then F10 on HP, or F1/Enter then F1 on Lenovo. Look for a Power or Battery section with a charge threshold or custom charge option, as covered in Fix #4.
How can I check if my battery is degraded or needs replacing?
Run powercfg /batteryreport from Command Prompt and compare Design Capacity to Full Charge Capacity in the generated HTML report. A gap larger than 30% suggests real wear.
Wrapping Up
Fix #2 (reinstalling the battery driver) clears up “plugged in, not charging” in most cases. Fix #1 catches the rest. A bad cable or underpowered charger is more common than people expect. If your battery seems stuck at a specific percentage instead, it’s almost never broken. Check your brand’s battery-health app first before assuming the worst.
