A malfunctioning laptop battery can be frustrating, especially when your device won't hold a charge or suddenly shuts down. Fortunately, before replacing it, you can try a simple laptop battery reset to fix power and charging issues. In this guide, we’ll show you how to reset your battery, troubleshoot common problems, and improve overall battery health.
What can you do to restore your battery?
The most obvious solution is to buy new ones. But it might be possible to reset the battery and fix the problem easily. While it may be difficult to repair a battery that refuses to charge completely, a battery that's only been used for a few years should work fine after inspection.
A reset allows the smart sensor to reconnect nicely to the laptop. This ensures more accurate power readings. In some systems, a proper reset allows the battery to be easily integrated with the battery. It will enhance proper compatibility and provide better system functionality.
Before starting the reset, it's important to determine why the battery is behaving abnormally. This will help you find the most appropriate treatment.
Why Your Laptop Battery Isn't Charging Properly
There are several reasons why a laptop battery loses its capacity over time. One of the biggest problems is the dramatic temperature change. This can adversely affect the normal operation of the battery, potentially degrading it over time and with heavy use.
You'll notice that your battery isn't storing as much energy as it used to. That's because of degeneration.
You can mitigate some of these issues with proper battery maintenance. Some problems may be due to fan dust, which requires direct methods like cleaning.
Why Do You Need to Reset Your Laptop Battery?
Over time, your laptop's "Smart Battery" sensor can lose its synchronization with the actual chemical charge of the battery cells. This is often caused by:
-
Frequent shallow discharges: Plugging the charger in and out constantly without letting the battery drain.
-
Temperature fluctuations: Heat can degrade the sensor's accuracy.
-
Aging: Natural degradation of battery cells.
When this happens, your OS might think the battery is empty when it actually has charge, causing the laptop to shut down prematurely. A reset (often called calibration) allows the smart sensor to "relearn" the true capacity of the battery, ensuring accurate power readings.
How to Reset a Laptop Battery
Method 1: How to Reset a Laptop with a Removable Battery
If you have an older laptop or a workstation model where the battery can be easily popped out, follow this "Hard Reset" method.
Step 1: Power Down. Shut down your laptop completely. Disconnect the AC adapter (power cord) and any external devices (USB drives, printers).
Step 2: Remove the Battery. Flip your laptop over. Slide the battery release latch and gently remove the battery from its compartment.
Step 3: Hold the Power Button. With the battery and power cord removed, press and hold the laptop's power button for 30 to 60 seconds.
Why? This drains the "residual power" stored in the capacitors on the motherboard, resetting the embedded controller that manages power.
Step 4: Reconnect and Restart. Insert the battery back into the compartment until it clicks. Connect the charger. Power on your laptop and check if the charging issue is resolved.
Method 2: How to Reset a Laptop with a Non-Removable Battery (Built-in)
Most modern laptops (like HP Envy, Dell XPS, or Lenovo Yoga) have sealed batteries. You cannot simply remove them. Instead, use the software reset method.
Step 1: Charge to 100% Plug your laptop in and let it charge until the battery indicator reaches 100%. Once full, leave it plugged in for an extra 2 hours to ensure the cells are cool and fully saturated.
Step 2: Discharge. Completely disconnect the charger. Use your laptop normally. To speed this up, you can increase the screen brightness and play a long video. Do not let it sleep/hibernate—you want it to drain until it shuts down automatically.
Step 3: The Wait Once the laptop shuts down, leave it off for at least 3–5 hours. This ensures any remaining residual charge is depleted.
Step 4: Charge Back to 100% Plug the charger back in and charge the laptop all the way to 100% without turning it on (if possible). Once fully charged, power it on. Your battery sensor should now be calibrated.

Troubleshooting: Drivers and Settings
If the physical reset didn't work, the problem might be a corrupted software driver.
Update or Reinstall Battery Drivers
The "Microsoft ACPI-Compliant Control Method Battery" driver communicates between your battery and Windows. If it’s corrupt, your battery won’t charge.
-
Right-click the Start button and select Device Manager.
-
Expand the Batteries section.
-
Right-click on Microsoft ACPI-Compliant Control Method Battery and select Uninstall device. (Don't worry, Windows will reinstall it automatically).
-
Restart your laptop. Windows will detect the battery and install a fresh driver.
Check Battery Charge Thresholds
Some laptops (Lenovo Vantage, Dell Power Manager, MyASUS) have a feature that stops charging at 60% or 80% to prolong lifespan.
-
Open your laptop manufacturer’s management app.
-
Look for "Conservation Mode" or "Battery Lifespan Mode."
-
Turn this feature OFF to see if the battery charges to 100%.
What to Do if Laptop Battery Still Not Charging
If your laptop battery is not charging, there are a few things you can do to fix it. Consider the following.
Troubleshooting the Hardware
One of the reasons your battery is not charging could be the hardware. Try fixing this. First, check if the power cable has issues. Drain the battery and then try charging it again.
If the battery is charging, the problem may be with the threshold. You can try another method, as we will discuss below. If it's not charging, your battery could be bad, or perhaps your AC has issues. Wherever possible, use a new adapter.
Turn the Battery Charge Threshold Off
For batteries that have threshold features, you can turn it off. The feature allows you to customize the charge threshold to stop charging once it reaches a certain point.
Do a laptop power reset?
A power reset could be all you need to fix your battery charging problems. Shut down the laptop and disconnect the adapter. Remove the battery and long-press the power button for 30 seconds. Restore the battery and turn it on. Your battery should start working properly.
Update your device's battery management device.
You could be missing an updated battery management system on your laptop. This can cause charging issues. Try to update this feature and see what happens.
Still Not Working? Replace the Battery
If none of the steps work, your battery may be damaged. We recommend replacing it with a high-quality, compatible model.
