How to Repair Laptop Battery not Charging — A Comprehensive Guide

Laptop batteries last for specific hours according to their capacities and build. After that, you have to plug in the power cable to your laptop. It might be threatening if you notice that you can’t charge the laptop battery even though you have inserted the power plug. 

Isn’t your laptop’s battery capable of holding the charge, anymore? Well, that’s subject to more inspection and diagnosis. Apart from battery damage or exhausted cells, numerous reasons can cause your laptop battery not to charge. Poor connection from the charging cable, overheating laptop, adapter issues, and software glitches can be triggering.

Therefore, you should have a clear understanding of why your laptop battery has stopped charging. Primarily, you can apply a few in-general troubleshooting steps. Then, you should learn how to repair laptop battery not charging if none of the solutions work. Let’s get started.

Common Solutions on How to Repair Laptop Battery Not Charging

You need not panic if the battery doesn’t charge because your laptop will stay awake with the charger plugged into it. However, you might be thinking about whether you have to repair or replace the battery. To reach that conclusion, you should go through the following fixes. These will help you to determine if it’s the battery’s fault or a temporary glitch.

So, go through the following solutions:

Check Power Cable Connections and Hardware Seams

Have you connected the laptop charger correctly? Well, this might sound vague but a moment of carelessness or loose connection can create an illusion of faulty charging. Therefore, double-check the connections between your laptop and the charger. In addition, tightly secure all other connections to make sure that there’s no hardware fault.

However, this doesn’t guarantee laptop charging if there are issues with the power brick, transformer, and AC or DC cable. In case you find nothing suspicious you can do one thing, drain your laptop’s existing battery power and then try to charge it. 

As a quick rescue, you can try another laptop charger to check if that works. Vice versa, you can try the first charger to charge another laptop’s battery. This will tell you whether you should blame the laptop charger or the laptop’s battery.

Detach the Laptop Battery

This isn’t applicable to the integrated battery-laptop system. However, you can remove your laptop’s battery if the device allows you to do so. Chances are there that your laptop might be overheating and the battery might not charge properly. So, drain your laptop’s battery entirely.

Remove the battery carefully when the laptop is turned off. Next, keep the battery aside for a minute or so. It will be better if you clean the battery with a soft, lint-free microfiber cloth. Next, place the battery in the laptop’s designated compartment and it should snap to its space. Insert the power cable into the laptop and start charging it.

Turn on the laptop and test if it eradicates the laptop battery not charging issue.

Disable the Battery Charge Threshold

A few laptops come with a battery charge threshold feature to save power. Most Lenovo ThinkPad laptops offer this feature and here’s how you can deactivate it:

  • Navigate to the “Lenovo Vantage” followed by its “Power” section.
  • Go to the “Battery Charge Threshold” option and toggle it off.

Test if your laptop battery starts charging after this.

Update the Battery Driver

The lack of the latest driver version might disrupt the battery charging process. Hence, you should update the battery devices’ drivers to eliminate such chances. Here’s how you can update battery drivers on a Windows PC:

  • Search for “Device Manager” using the “Start” menu.
  • Open “Device Manager” and expand devices corresponding to batteries.
  • Mostly, there are two devices for laptop batteries.
  • Right-click on each device and select the “Update Driver” option from the pop-up menu.
  • Go for the automatic update and restart your laptop.

Attempt charging your laptop battery and check if the issue persists.

Reinstall the Battery Drivers

Perhaps, a battery driver reinstallation might eradicate the charging issue. Go to “Device Manager” on your Windows PC and locate the “Microsoft ACPI-Compliant Control Method Battery” device under “Batteries”. Right-click on it and opt for the “Uninstall Device” option. Confirm the prompt and turn off your laptop.

After that, remove the AC adapter along with the battery, if detachable. Long-press the power button of your laptop for around 30 seconds. Place your laptop’s battery back in its place. Try charging the laptop and turning on the device. This will automatically reinstall the latest version of the Microsoft ACPI-Compliant Control Method Battery device.

Recover a NiCD or NiMH Battery

Does your laptop own a Nickel-Cadmium or Nickel-Metal Hybrid battery? Then, you can try this hack to revive the battery. On a strong note, don’t go for this method if your laptop uses a Lithium-Ion battery. Additionally, this method is not for any Mac device as all of them come with Lithium-Ion batteries.

Go through the guidelines below to revive a NiCD or NiMH battery:

  • Turn off your laptop and stop charging it if you have plugged the power cable into it.
  • Detach the laptop’s battery and keep it in a zipped bag. Moreover, the bag should be soft and waterproof. Make sure that you should not use any ordinary plastic zip lock bag to contain the battery. Otherwise, moisture will dump the battery and damage it.
  • Next, place the bag with the battery in a freezer. You need to keep the battery like that for a minimum of 10 hours. Ensure that you bring out the bag from the freezer before it’s more than or equal to 12 hours.
  • Let the battery reach room temperature. Consider a dry cloth wrapped around the battery to prevent damage from moisture.
  • Now, you can place the battery back in your laptop once it reaches room temperature.

Test if the charging difficulties have disappeared or not.

How to Repair Laptop Battery Not Charging?

We assume that you are still stuck with a laptop battery that refuses to charge at any cost. Perhaps, the battery is dead but you can repair your laptop’s battery at an affordable cost. Let’s see how to repair laptop battery not charging.

Remove the Laptop Battery

Mostly, a laptop battery lasts a specific number of charging cycles. Roughly, a laptop battery should sustain for 2 years or slightly more than that. After that, cells inside the battery might go dead. For this handy repair, drain the laptop battery completely and then remove it from the device.

Open the Battery

Use a flathead screwdriver to carefully expand the seams of the laptop battery. Take your time and carefully open its casing. Mostly, they are glued using a powerful adhesive. Once you have opened the enclosure you should notice cells inside the laptop battery. 

Generally, the number of batteries can vary from 4 to 8. Write down their specifications, order, and circuit connection so that you can implement a successful cell replacement. Additionally, note down how the cells are forming the circuit: whether they are in series or parallel connection. Capture the original circuit configuration for better help.

Get Old Cells out of the Battery

Be careful while cutting the plastic coverings all over the old cells. Don’t worry as this won’t expose the cells. Remove the connecting wires to the cells from the charging tray. Keep new cells ready for replacement. You can purchase new cells from e-commerce websites.

Put New Cells in the Battery

Now, remove the plastic wraps of the new batteries and place them in their exact positions. Ensure that you match their specifications and check the voltage reading before installing them inside the laptop’s battery. Make a successful connection by placing them in a series or parallel formation. 

Next, restore the connection between the cells and the charging tray. You can either solder the connection or tape the connection with an industrial and reliable insulating tape.

Assemble the Laptop Battery

You can test the battery voltage using a multimeter. If everything looks justified, you can join those two battery halves with a powerful adhesive. Install the battery back into the laptop compartment. Remember to charge those new cells overnight before using them.

When Should You Replace the Laptop Battery?

Certain signs indicate the laptop requires an immediate battery replacement. If your laptop’s battery drains its charge too soon or it can’t hold 25% of the total anticipated power then you should consider a battery replacement. Additionally, you might notice overheating, frequent shutdowns, and swollen battery compartments. Consult with an expert to learn whether it’s time to repair or replace the laptop battery.
