If you’re searching for how to fix a laptop that won’t charge, you’re likely dealing with a laptop that either shows “Plugged in, not charging” or doesn’t respond at all when connected to power. This issue is more common than you might think—and the good news is, most charging problems are fixable without replacing your device. This guide offers 10 proven fixes to help you get your laptop charging again.
Signs Your Laptop Isn’t Charging Properly
- Battery percentage never increases
- “Plugged in, not charging” message appears
- No charging indicator light when plugged in
- Laptop only works when charger is connected
Step 1: Check the Power Source
Make sure the wall outlet is working by plugging in another device. Avoid using power strips or extension cords during initial troubleshooting. Plug the charger directly into the wall to rule out power delivery issues.
Step 2: Inspect the Power Cable and Adapter
Look for visible damage, frayed wires, burnt smells, or bent connectors. If available, test with another compatible charger. Using third-party or incorrect voltage chargers may prevent proper charging or damage your battery.
Step 3: Check the Charging Port
Inspect the laptop’s charging port for dust, debris, or physical damage. Use compressed air to clean the port gently. If the port feels loose or unstable, internal repair may be required.
Step 4: Reboot and Perform a Hard Reset
Shut down the laptop, unplug the charger, and remove the battery (if removable). Hold the power button for 30 seconds. Then, reconnect everything and try powering up and charging again. This can reset power management components.
Step 5: Update or Reinstall Battery Drivers
Go to Device Manager > Batteries > Microsoft ACPI-Compliant Control Method Battery. Right-click and uninstall the driver, then restart your laptop. Windows will reinstall it automatically. Also, check for BIOS and chipset driver updates from the manufacturer’s website.
Step 6: Run the Battery Troubleshooter (Windows)
Navigate to Settings > System > Troubleshoot > Other troubleshooters > Power. Run the built-in diagnostic tool to detect and fix battery-related configuration issues automatically.
Step 7: Check for Overheating or Battery Swelling
Overheated batteries or internal swelling may cause charging to stop for safety reasons. Check if the laptop gets abnormally hot or if the touchpad/bottom bulges. If so, turn off the device immediately and seek professional help.
Step 8: Test with the Battery Removed
If your laptop has a removable battery, take it out and try powering the laptop using just the AC adapter. If it powers on, the battery may be dead or damaged and need replacement.
Step 9: Reset BIOS/UEFI Power Settings
Enter the BIOS/UEFI setup during startup (usually by pressing F2, Del, or Esc). Load “Optimized Defaults” or “Reset Settings” and save changes. Misconfigured BIOS settings can block charging recognition in rare cases.
Step 10: Consider Battery Replacement or Repair
Laptop batteries degrade over time, typically after 300–500 cycles. If your battery is more than 2–3 years old or fails all other checks, it’s likely time for a replacement. Always use official batteries from your laptop brand for safety and compatibility.
Still Wondering How to Fix a Laptop That Won’t Charge?
Charging issues can often be solved with basic steps like checking the adapter or updating drivers. However, if you’ve exhausted these solutions, consult a certified technician to avoid damaging your device further. Regular battery maintenance and quality accessories can prevent future problems.
