Laptop's battery

One of the worst encounters for a laptop owner is getting ready to take it off the cord, only to discover the laptop hasn't changed. There could be a variety of reasons why your laptop battery is not charging. We'll start with investigating its health.

How Do I Check the Health of My Laptop Battery?

Laptops without their batteries may as well be stationary computers. The battery inside a laptop makes up the core features of the device - mobility and accessibility. That's why it's imperative to check the health of your battery. We want to prolong its life as long as possible. Not get caught with a battery failing on the go!

If you run Windows, you can investigate your laptop battery health by:

  1. Right-clicking the start button
  2. Select 'Windows PowerShell' from the menu
  3. Copy 'powercfg /battery report /output C:\battery-report.html' into the command line
  4. Press enter
  5. A battery health report will be generated into the 'Devices and Drives 'folder

You will then see a report that analyzes battery usage and its health, so you can make decisions about when and how to charge it. However, there are instances where the battery does not appear to be demanding. We'll explain that scenario below.

Why Is My Laptop Not Charging When Plugged In?

If your laptop has ceased to charge, there are usually 3-reasons behind the issue. We'll list the most common causes below.

  1. The charging cord is faulty.

Many will find that this is the primary issue behind laptops not charging. The quality of the accompanying cords to power the batteries is surprisingly low. You can check if this is the case by:

• Seeing that the plug on the wall and the line inside the charging port are securely positioned
• Moving the cable around to check for a broken connection
• Trying the cord in another person's laptop and see if it works

  1. Windows has a power issue.

It's not uncommon to see that the Windows operating system itself has an issue with receiving power. Luckily, this can be checked and remedied relatively easily with the process below:

• Open the 'Device Control Manager'
• Select 'Batteries'
• Select Microsoft ACPI-Compliant Control Method Battery driver
• Right-click and uninstall
• Now scan for hardware changes at the top of the 'Device Control Manager' and let it reinstall

  1. The battery itself has failed.

If both the above aren't working, it may be you have a faulty battery. Most laptops have the option for a diagnostics test as soon as you start up the computer (before you reach the Windows login screen). Should you be prompted, try checking the battery here. If there is a known problem or you just can't get it fixed, it will need repair or replacing.

How to Repair a Laptop Battery That's Not Charging
While taking your laptop battery to a specialist is recommended, there are some home methods you can try to revive it. Those include:

• Freeze the battery in a Ziploc bag for 12-hours, and then try charging it again.
• Cool your entire laptop down with a cooling pad
• Let your battery drain down to zero, remove it for 2 hours, and place it back

If none of these methods work, you may need to completely replace your laptop battery.
