How To Fix Laptop Lagging While Charging?

Check if your charging cables are damaged

Sometimes the laptops start lagging when you connect them to a faulty charging cable. You can find out if the issue is with the cable by seeing how long it is taking to charge your device, or if there is any visible damage to the cable. Sometimes a faulty cable even tends to destroy the battery of the laptop, causing you more damage. 

Thus, try changing and using a different charging cable. If the issue is the cable in the first place, the laptop will start working smoothly again. Cables that are damaged can cause internal short circuits and might not provide enough power that the device needs causing it to lag slowly.

Check if the system is overloaded

In case you’re opening too many tabs or applications, your system might be overloaded and hence lagging a lot. Thus, if your laptop is lagging when plugged into a charger, maybe the issue is not the charger but the configurations of your system. 

To check if there are other running applications or tabs, press CTRL + ALT + DEL. If there are any running processes, then close them by clicking on ‘End Task’. This will free up some of your device’s resources so that it stops getting slower with time and reduces lag while charging.

Also, check the configuration of your device and find out if it is enough for the work that you are doing on your device. Like, if you are gaming on a minimum configuration laptop while it is put on charge, it will not definitely start lagging in no time. Thus, having suitable configurations and using the device without overloading can help you use your laptop more smoothly without any delays. 

Use a decent cooling system

Use a decent cooling system

The rise in temperature of the laptop while it is charging is very common. No matter if you have decent configurations on your device, or if there is no problem with your charger, if your laptop’s temperature is rising, the device will slow down. 

This might happen if you have placed your laptop on a less breathable surface or if you are overloading your device. Like, while gaming, programming, and even editing, the laptop is processing a lot, and because of being under constant load, it can heat up. 

The simple solution for this issue is to use a decent cooling system on your laptop, you can set up fans or heatsinks to keep your device cool. You can also use external laptop cooling pads to maintain the temperature of the device, and this might solve your issue. 

Run your laptop on an AC power supply

This is another solution that you can try if you can’t figure out why your laptop is lagging when plugged into a charger. While charging, the battery often overheats, and if it is the battery that is causing the speed of the system, a reliable option is to take it out. 

You can run your laptop on an AC power supply without having a battery. This way your laptop will not have to deal with an overheated battery and will run smoothly while maintaining a reliable temperature. 

Check if your BIOS needs updating

Check if your BIOS needs updating

Computers may lag while charging if your BIOS needs updating. If you’re using Windows, go to Control Panel > System and Security > Device Manager. You will see a listing for Laptop or Tablet. Under it, you should see a sub-listing for the Central Processing Unit followed by the BIOS Version. Right-click on it and select Update Driver Software. 

Search online to find out if there is an updated version of your CPU’s BIOS. Then install it on your computer. Updating outdated drivers is always a good idea if they aren’t already up-to-date. Doing so could resolve other problems with your PC as well. 

Check the power adapter

It might seem odd that a broken power adapter would cause your laptop to slow down while charging. But that’s exactly what can happen. A damaged power adapter can cause fluctuations in voltage, which affect how quickly your laptop charges and how efficiently it uses electricity. 

It can also create electromagnetic interference, which interferes with data transfer between components inside of your PC. To test whether or not it’s time for a new power adapter, try plugging it into another wall outlet to rule out any issues with outlets near where you normally charge your device.

Clean out all clutter on the computer

As a general rule, it’s never a good idea to have extra programs on your computer, especially so when it’s charging. It’s easy for clutter to build up, and it slows down computers. Especially laptops, which tend to be more susceptible than desktops. 

Before you do anything else, make sure you go through all of your downloads and get rid of anything that doesn’t work or isn’t necessary. Then look for other unnecessary programs and delete those as well. You might even consider uninstalling Facebook and other apps that use excessive amounts of memory since they can slow down your computer while it charges.

Try changing the power settings

Using your device on the right power plan setting is very important for a reliable experience. Most people tend to go for the high-performance mode so that they can work on heavy tasks smoothly. But what they ignore is that it might slow your device down by overloading it. Thus, keeping the power plan setting as Balance is the most reliable route you can take. 

To change the power plan settings, go to the start menu and open the settings tab. On there, click on the power and battery option, and from the dropdown menu, choose the better performance. Then open the control panel, go to the power options and change the power plan setting from high-performance mode to balance mode. 

Use your laptop for a while. After that while, the charge is still connected to the device to see if the laptop is still lagging or not. If not, you are finally rid of the issue that has been causing you slow speed. 

Reinstall windows

This might not be the most recommended option, but it can sometimes work. If nothing seems to work to get your laptop to start working smoothly while charging, try reinstalling your windows. And maybe that will improve the overall speed of your device. 

Use your laptop without a charger

This is not a solution but more of a suggestion. If your laptop comes with an impressive battery life, which is somewhere around 10 hours, or above, try using your device without the charger. You might need to take some charging breaks in between if you are working on some larger projects. But it will prevent your system from compromising its speed. Thus, it is always an option to avoid using the charger while working on your system.
