What Do To When Your Battery Is Plugged In, Not Charging

When you hover the mouse cursor over the battery icon in the system tray, it shows you the current charge state of the battery. If your laptop is plugged in, a small tool tip will tell you how charged it is as a percentage. If your battery is fully charged, the tool tip will say just that. In the event that you’re not connected to a power source, the tool tip will tell you how much charge is left. It will tell you how many hours the battery will last, and what percentage of it is left. This is what happens when you have a healthy battery. If you start seeing the ‘Plugged in, not charging’ tool tip though, it’s a cause for concern.

The ‘Plugged in, not charging’ message is straight forward; your battery isn’t charging. It’s not the message that’s difficult to figure out. It’s the cause behind that’s the problem. In most cases this is a hardware problem though it can be driver related as well.

A Software Issue

Driver Limitations

You might have heard that batteries go through charge cycles. A single charge cycle is the battery fully charging and then discharging. The more charge cycles a battery goes through, the lower its life becomes. This is inevitable. Much like you can’t stop a person from aging, your battery will eventually age and die.

To slow down the process though, some drivers limit charging beyond a certain point. If you see the Plugged in, not charging message after your battery reaches 95% charge, then it might be a driver limitation. Check if the battery still charges if it’s at 50% charge. If it does, your battery is in good health.

BIOS Update

This is a somewhat obscure cause but an outdated BIOS might be what is causing the problem. Check if a new version of your BIOS is available and update it.

Microsoft ACPI-Compliant Control Method Battery

This is a driver that Windows installs on your laptop to manage your battery and power input. It works well for the most part but it can also cause problems. Try uninstalling this driver and check to see if your battery starts to charge. If not, you likely have a hardware problem on hand. Download the driver again and proceed to the next section.

A Hardware Issue

Faulty Power Supply

A faulty power supply, or an incompatible power supply will prevent your battery from charging. Check the following;

  1. The power supply is properly plugged in. The power socket or extension cable you’re using is not faulty. Try to change the socket you’re laptop is plugged into. Make sure you’re using a direct current and not a battery supplied one i.e., a UPS to power your laptop.
  2. The power supply should be the original one that came with your laptop. Some manufacturers prevent third-party power supplies from working with their hardware. Also, all power supplies are not created equal because all laptops don’t have the same power requirements. If you use the power supply of an HP laptop that’s low end with a high end HP laptop, you are likely going to encounter problems.
  3. Unplug everything, plug it in again, and see if the problem goes away.
  4. Try a different power supply. Make sure the power supply you’re using is compatible in terms of manufacturer and output and see if it will charge your battery.

Dead Or Dying Battery

Batteries die and that is the sad and final conclusion you have to come to if the plugged in, not charging message doesn’t go away. This shouldn’t be the case if you have a new laptop but if your laptop is over 5 years old then consider replacing the battery.

Laptop batteries last for shorter amounts of time as they age. The final stage is when they stop charging. If all else fails, it’s time to replace the battery. You might want to take your laptop in for a quick check and see if there’s a problem with the hardware but again, a 5 year old battery is at the end of its life.

Batteries aren’t expensive though. Your only problem is to find the correct one for your laptop.

It Charges Sometimes

The Plugged in, not charging message goes away one its own at times. This might be indicative of a battery that’s ┬ánearing the end of its life or a faulty power supply. If you’re intermittently seeing the plugged in, not charging message then it’s time to check your battery health. Try to change the power supply unit. Proactively tackle this problem because the battery might die suddenly and you could lose data if you aren’t connected to a power source.
