Solve the problem of slowing down when charging an Acer, HP or Dell laptop

Your Acer, HP, or Dell laptop runs slowly while charging, but works well when powered by battery? don’t worry! This article will introduce several effective solutions to help you solve the problem of "slower charging when your laptop is charging".

Laptop slows down when charging

It is usually recommended that users plug the laptop in to use for optimal performance. However, many users find that their laptops are slower when charging. Typically, problems with device latency or slow speed are related to laptop overheating, incorrect power management settings, virus attacks, or hardware failures.

Next, we'll learn how to fix the problem of slow running while charging your laptop.

Method 1: Prevent the computer from overheating

Overheating of laptops is an important reason for computer performance degradation and slowdown. You can check the temperature of your laptop using the CPU temperature monitor. If your laptop temperature is above 70 degrees Celsius, you may want to consider the following:

• Place the computer on a flat, hard surface to make sure the vents are not clogged.
• Clean the laptop fan with a dry small brush or glasses cloth dipped in a small amount of alcohol and make sure the cooling fan is working properly.
• Close applications that use a large number of system resources.

Method 2: Check whether the power adapter is faulty

Charging the device with a failed power adapter can also cause the computer to run slowly while charging. To rule out this, make sure you are using the original adapter from your laptop. If that doesn't work, use another power adapter that is compatible with your laptop.

Method 3: Change the power plan

A power plan is a set of hardware and system settings (such as display, sleep, etc.) that manages how the computer uses power. To resolve the issue of "slower charging when laptops are charging", you can follow these steps to change the power plan:
