A Quick Fix

A number of reasons can cause the system to lag but the most common culprit is heat! So, the best way for you to avoid it is to unplug your charger for a bit. Yes, it will drain your battery, but it is a temporary and quick fix that won’t cost you the game.

Why Is Laptop Lagging When Charging?

You might be wondering, why does my laptop lag when charging? Well, there could be a number of reasons causing the problem. Let us look at the most common ones which might be the culprit behind your system lags.

1- Turbo Boost

Most gaming laptops come with something called the ‘Turbo Boost’. It is an inbuilt feature that allows your system to run at maximum power when required. That is a plus point, but it also has a downside. When running on Turbo Boost, your system tends to slow down and lag to enhance performance.

Unfortunately, you can’t turn off Turbo Boost. But you can definitely limit your CPU consumption to avoid turning on Turbo Boost. Go to system settings and set your CPU to run at only 99% capacity. This will prevent your laptop from lagging when charging when running high-end energy-consuming games.

2- Thermal Throttling

As the name suggests, heat is the next major culprit. When your system is running at its full capacity it tends to overheat and that is when the fan kicks in. Since it is already overheated, the energy drawn from the battery plug adds additional heat to the system which causes it to slow down.

It is an in-built feature of high-end laptops. Their components are designed to slow down when overheated to prevent permanent damage. Accumulation of heat can force your system to slow down, hence removing the plug for a while can help cool it down.

3- Malfunctioned Charging Adapter

Sometimes your energy supply is the problem. Games lag when the laptop is plugged in using a faulty charger. You might have heard professionals say that you should only use supported and compatible adapters for your electronic devices. Many of us tend to ignore their advice, but they are right! Using incompatible chargers with your laptop can cause damage to the battery and the system’s processor, hence causing lag.

Improper voltage influx can not only hinder your performance but can also fry your hardware. So, it is best to avoid incompatible chargers with your system. Either stick with the one that came with the box or the universal chargers to avoid lag and damage.

4- Faulty Battery

If your system only lags when it is plugged in, then your battery might be the culprit. In order to check, simply remove the battery and run your system directly. If there is no lag, then you have found the problem. Simply replace it or run the system without it.

5- Outdated Drivers

Lastly, your system’s drivers might be outdated as well. When your software is not compatible with the hardware, it often prevents it from running at full capacity which can cause it to lag, especially when gaming.

The Laptop Is Lagging When Charging? [Solutions]

Now that you know the causes, it should be easier to figure out a solution. Here are a few solutions that have worked for us in the past. Give them a try and hopefully, your system won’t lag anymore during intense gaming sessions.

1- Limit Your CPU

Firstly, if your system has a Turbo Boost feature, you need to limit your CPU consumption. You should know that the Turbo Boost is only activated when your CPU is running at 100% capacity. Therefore, the best approach is to limit it to 99% and you should be good to go.

2- Ensure Proper Cooling

Heat is always going to be a problem. There are various ways in which you can prevent your system from overheating. We suggest you start by closing down all the unwanted applications that are running in the background. Then ensure your system is placed on a hard surface and the air vents are not clogged.

If all of these solutions don’t work, then getting a cooling pad is your best solution. It will provide additional support to the processor and the surrounding components and will prevent them from overheating when plugged in and running at maximum capacity.

3- Invest in a Suitable Charger

If your charger is the issue, make sure to invest in a compatible one. You can visit the nearest electronics store and ask them for a charger that is recommended by your manufacturer. If not, you can always invest in a universal charger.

4- Update OS and Drivers

Make sure your system and related gaming drivers are always up to date. Whether it is the CPU or the GPU, any of them running with outdated drivers can be the cause. So, keep checking for updates suggested by your manufacturer and OS provider. If it doesn’t work, then you can always reinstall the window.

5- Remove the battery

When the battery is at fault, removing it is the simplest option. But this solution might not work for everyone as some laptops do not come with detachable batteries. So, if you can detach your battery, then go for it as it will take off the stress and burden from your CPU and prevent it from lagging.

6- Restart your laptop

Sometimes the simplest solution is to restart your laptop. Sometimes there is just so much running in the background that prevents your system from giving its optimum performance. Give your system a break, and it will just get back to normal, running smoothly.

Frequently Asked Questions

1-     Is it better to use the laptop plugged in or on battery?

If you use your laptop for high-end, power-required purposes, then running it while it is plugged in is the best option. The reason is that it prevents the battery from draining and recharging over and over again, which can reduce battery cycles.

2-     Can games damage your laptop?

Not really! Anything that is used excessively tends to get damaged. The same is the case with gaming and laptops. If you are a regular gamer, then your device is likely to get damaged much faster than a laptop that is only used for school work. But it takes years for your laptop’s components to wear out, so you have nothing to worry about.

3-     Does gaming decrease the battery health of the laptop?

Not specifically. You need to understand that batteries come with specific charge cycles. When gaming, your system tends to draw a lot of power, which drains the battery and hence requires constant charging. This means your charging cycles will be used much faster as compared to a laptop that is used regularly. Therefore, it only affects your battery and not the laptop in any way.

4-     How do I get rid of lag on my laptop?

Games lag when the laptop is plugged in. The best way to avoid lag is to let your system cool down. You can either close unwanted applications or unplug your laptop from power. Other than that, you can also add a cooling pad as it prevents your system from overheating.

5-     Is it bad to keep the laptop plugged in when fully charged?

Yes, definitely! When your system is plugged in, it is exposed to excessive energy which causes overheating that can damage your battery and other hardware. In the short run, you might not see a difference. But after a year or two, your battery’s capacity will be significantly reduced.


Lastly, laptop lagging when charging is a common issue and can be caused by a number of reasons. It can be hardware-related or software related. There is no need to stress. Give the system and yourself a break, have a look at it again, and figure out the problem.  Once you have that figured out, finding a solution is easy. We have provided you with a list and hopefully, these solutions will help solve your lagging issue.
