Why My Laptop Won’t Charge Past 50%? – (Causes & Fixes)

Although I have a MacBook Pro M1 (2020), I prefer my Windows laptop for daily office work.

Windows 10 is my favorite OS because it supports full customization, high-performance gaming, and supports wide-range of third-party software.

But Windows 10 is not free from bugs. I’m saying this because last week, I had to leave for another city for office work, and I noticed my laptop was not charging beyond 50%.

It was a panic situation because 50% battery could not last the whole day, and some important work was still pending.

Thankfully all my important documents were stored on Google Cloud, and I took the help of my MacBook.

After returning from office work, I did some online research to understand why my laptop won’t charge past 50%.

I noticed thousands of Windows users from different laptop brands were facing similar issues. I diagnosed my machine and found that third-party software was the main culprit.

However, there could be several more reasons why your laptop battery won’t charge fully. I’ll discuss all the reasons in this tutorial and guide you step-by-step process to fix the issue.

These are some common reasons why your laptop battery is not charging 100 percent.

1. Defective Battery

The first and the most common reason why your laptop battery is not charging fully could be a defective battery.

A damaged or faulty battery won’t hold the charge, and your laptop will run out of power quickly.

If you’re using an older laptop, then it’s quite likely that the battery has reached the end of its lifespan. In such a case, you need to replace the battery with a new one.

2. Power Management Issues

If your laptop is not charging beyond 50%, then it could be due to power management issues.

Windows 10 has a feature called “Battery Saver” to prolong the battery life of laptops.

When this feature is enabled, it limits the background activities and reduces the screen brightness to save power.

However, sometimes this feature causes problems, and the laptop doesn’t charge beyond 50%.

3. Third-Party Software

Another reason for your laptop not charging fully could be third-party software.

These days, most laptops come with pre-installed bloatware that hogs system resources and battery power.

So, if you’re using a lot of third-party software, then it can cause power management issues and prevent your laptop from charging beyond 50%.

4. Outdated Drivers

Update Battery Driver

If you’re using an older laptop, then it’s quite likely that the drivers are outdated.

Outdated or corrupt drivers can cause all sorts of problems, including power management issues.

So, if your laptop is not charging beyond 50%, it could be due to outdated drivers.

You can update the drivers manually or use a reliable driver updater tool to do it automatically.

5. Hardware Issues

If you’ve ruled out all the software-related issues, then it’s quite likely that there’s a hardware problem.

It could be a faulty power adapter, a damaged charging port, or a defective battery.

In such cases, you need to take your laptop to a certified technician to get it fixed.

What To Do If Laptop Battery Won’t Charge Fully?

Now that you know all the possible reasons for your laptop not charging beyond 50%, it’s time to learn how to fix the issue.

Here are a few troubleshooting tips that can help you fix the problem:

1. Check the Battery Health

The first thing you need to do is check the battery’s health. If the battery is damaged or faulty, it won’t charge 100%.

Many laptop brands provide software to check battery health. You can install the battery health checker tool and run a diagnosis.

I’m an Asus user, and it has a built-in MyAsus App to check battery health.

Here’s how to do it:

3. Update the Drivers

If your laptop is not charging beyond 50%, it could be due to outdated drivers. You need to update the drivers to fix the issue.

5. Take It to Service Center
