How to Fix Laptop Lag When Plugged in Windows 11

So, if you’re annoyed with lag or slow down due to incorrect power management settings of Windows 10/11, continue reading the guide. Below, we have shared some simple methods to fix Laptop lag or slowdown when charging it on Windows. Let’s get started.

1. Ensure your device is not overheating

Excessive heat is a prominent reason for laptop lag or slowing down while charging issue. When a laptop is charging, a part of the energy is converted to heat, which needs to be dissipated.

When the heat doesn’t get its way to release, it builds up and increases the temperature of other hardware components. This is what leads to sluggish performance.

So, you must ensure your laptop is not heating up while charging. If it’s overheating, you can use a laptop cooling pad. Also, make sure the heat sink of your laptop is not clogged up with dirt, and the fans are working properly.

2. Make sure your Power Adapter is in good condition

The faulty power adapter is another prominent reason for laptop overheating or charging problems.

You won’t face any problems if you are using the original power adapter that came with the laptop box. However, if you are using a third-party power adapter that’s too old, you can expect overheating or charging problems.

Using an incompatible power adapter to charge your laptop will lead to excessive heating and damage to the other hardware components.

So, to lengthen the battery life and to fix issues like Windows Laptop lag while charging, make sure to use the original power adapter.

3. Change the Power Settings

As noted above, incorrect power plan settings can lead to laptop lag or slowdown while charging. This is because the Battery Saver mode of Windows eliminates certain processes to retain the battery juice.

So, if your laptop is in battery saver mode, you can try turning it off to fix laptop lag while charging. Or else, you can change the Power Mode settings to fix the problem. Here’s what you need to do.

1. Click on the Windows Start button and select Settings.

2. When the Settings app opens, switch to the System tab on the left.

3. On the right side, click on the Power & Battery.

On Windows 10/11, you don’t need to use any third-party security tool to scan your PC for security threats. The built-in Windows Security is powerful enough to handle all security threats.

A laptop slowing down out of a sudden can also be a sign of a virus/malware infection. Hence, it makes sense to run a full antivirus scan with the Windows Security app to fix the root cause. Here’s how to perform a full virus scan on Windows.
