Wrong charger wattage — Using a charger with lower wattage than your laptop requires can result in the laptop not charging properly.
Charge threshold settings — Some brands (Lenovo, ASUS, Dell) include software that stops charging at a set percentage to preserve battery health.
Outdated BIOS — Old BIOS firmware can cause charging miscommunication between the motherboard and the battery.

How to Fix Laptop Battery Not Charging (12 Step-by-Step Methods)

Here are 12 proven methods to fix a laptop battery not charging. Start from Fix 1 and work your way down. The simplest solutions come first.

Fix 1: Check Your Charger and Cable

Why this works: A damaged charger is the number one reason behind a laptop battery not charging. Physical damage is easy to miss.

Steps:

Unplug the charger from the laptop and the wall outlet.
Inspect the entire cable for cuts, bends, or fraying.
Check the charging tip for bent or blackened pins.
Feel the adapter brick — if it’s extremely hot or smells burnt, it has likely failed.
Test with a different compatible charger if available.

Fix 2: Try a Different Power Outlet

Why this works: A tripped breaker, loose outlet, or faulty surge protector can silently cut power, making it look like your laptop won’t charge.

Unplug the charger from the current outlet.
Plug it directly into a different wall outlet — skip power strips and extension cords.
Wait 30 seconds and check if charging begins.

Fix 3: Perform a Hard Power Reset

Why this works: A hard reset clears residual electrical charge from the motherboard that can block battery charging. This is the single most effective fix for the “plugged in, not charging” problem.

Steps:

Shut down the laptop completely (don’t just close the lid).
Unplug the charger.
Remove the battery if it’s removable.
Hold the power button for 30 seconds.
Reinsert the battery.
Plug the charger back in.
Turn the laptop on.

This fix resolves the laptop battery not charging issue on Dell, HP, Lenovo, and most Windows laptops.

Fix 4: Remove and Reseat the Battery

Why this works: A loose battery connection interrupts charging signals, making your laptop battery not charge even when plugged in.

Power off the laptop.
Flip it over and locate the battery latch(es).
Slide the latch and carefully remove the battery.
Wait 60 seconds.
Reinsert the battery firmly until you hear a click.
Turn on the laptop and plug in the charger.

Note: If your laptop has a built-in non-removable battery, skip to Fix 6.

Fix 5: Check for Overheating

Why this works: Laptops have thermal protection circuits that automatically pause charging when temperatures are too high. Overheating is a hidden cause of laptop battery not charging.

Feel the bottom of your laptop. Is it unusually hot?
If yes, shut down the laptop and let it cool for 15–20 minutes.
Make sure vents are not blocked by blankets, pillows, or dust.
Place the laptop on a hard, flat surface.
Try charging again once the laptop cools down.

Fix 6: Update or Reinstall Battery Drivers (Windows)

Why this works: The battery driver tells Windows how to manage charging. A corrupted driver is a top reason for the laptop plugged in not charging error.

Steps:

Right-click the Start button and select Device Manager.
Expand the Batteries section.
Right-click Microsoft ACPI-Compliant Control Method Battery.
Click Uninstall device.
Click OK to confirm.
Restart your laptop.

Windows automatically reinstalls the driver on reboot, often fixing the laptop battery not charging problem instantly.

Fix 7: Run the Windows Power Troubleshooter

Why this works: Windows includes a built-in tool that automatically detects and fixes common power and battery not charging problems.

Open Settings (press Windows + I).
Go to System > Troubleshoot > Other troubleshooters.
Find Power and click Run.
Follow the on-screen instructions.
Restart your laptop after completion.

(On Windows 10: Settings > Update & Security > Troubleshoot > Additional troubleshooters > Power.)

Fix 8: Adjust Battery Charge Threshold Settings

Why this works: Some manufacturers include software that limits charging to 60% or 80% to prolong battery life. If enabled, your laptop battery won’t charge to 100% — and it’s working as intended, not broken.

Where to check:

Lenovo: Open Lenovo Vantage > Battery Settings > Conservation Mode → Turn OFF.
ASUS: Open MyASUS > Battery Health Charging → Switch to Full Capacity Mode.
Dell: Open Dell Power Manager > Battery Information → Check charge settings.
HP: Open HP Battery Health Manager in BIOS.

Fix 9: Check and Update BIOS Settings

Why this works: The BIOS controls low-level hardware functions including battery charging. An outdated BIOS is a known cause of laptop battery not charging on many models.

Restart your laptop.
Immediately press F2, F10, DEL, or ESC to enter BIOS (varies by brand).
Navigate to the Power or Advanced tab.
Ensure battery charging options are set to Standard or Enabled.
Check your manufacturer’s website for a BIOS update and install if available.
Save and exit.

Warning: Only change BIOS settings you understand. Incorrect changes can cause boot issues.

Fix 10: Reset the SMC (MacBook Users)

Why this works: The System Management Controller (SMC) manages all power and battery functions on MacBooks. Resetting it clears charging errors that cause a MacBook battery not charging issue.

For Apple Silicon MacBooks (M1/M2/M3/M4):

Shut down the MacBook completely.
Wait 30 seconds.
Turn it back on. (SMC resets automatically.)

For Intel-based MacBooks:

Shut down the MacBook.
Press and hold Shift + Control + Option + Power button for 10 seconds.
Release all keys.
Turn on the MacBook.

Fix 11: Calibrate Your Laptop Battery

Why this works: Over time, the battery sensor loses accuracy and displays incorrect charge levels, sometimes making it appear that your laptop battery is not charging when it actually is.

Charge the laptop to 100%.
Keep it plugged in for 2 additional hours.
Unplug and use the laptop until it completely dies.
Leave it powered off for 5 hours.
Charge it back to 100% without interruption.

Repeat this calibration every 2–3 months to maintain accurate battery readings.

Fix 12: Replace the Battery or Charger

Why this works: If none of the fixes above resolve your laptop battery not charging issue, the hardware itself has reached the end of its lifespan.

How to check battery health:

Windows: Open Command Prompt as Admin and type powercfg /batteryreport. Open the generated HTML file to see current capacity vs. original design capacity.
MacBook: Click Apple Menu > System Settings > Battery and check the battery condition.

When to replace:

Battery health is below 40–50%
Battery is visibly swollen or bulging
Laptop only works when plugged in
Battery charges to less than 20% and dies quickly

Always buy OEM or manufacturer-certified batteries and chargers.
