It can be incredibly frustrating when your FPS drops suddenly and inexplicably. You’re in the middle of an intense firefight or racing to the finish line, and then – bam! – your framerate takes a nosedive.

Or even worse, You might be sitting in a coffee shop, working on your laptop. The Wi-Fi is strong, but as you start to get into the flow of your work, you notice that your FPS starts to drop. Suddenly, it feels like you’re working on your laptop from 1997. 

What’s going on? Why does my FPS drop when I unplug my laptop? As it turns out, there are a few different reasons why your FPS might suffer when you unplug your computer. 

Thankfully, we’ve got the answer. In this article, we’ll explain what causes your FPS to drop when you unplug your laptop, and how to fix it. So read on and put an end to those pesky framerate issues!

So stay strapped because we are going for a ride!

Couple Of Reasons Why Why Does My Fps Drop When I Unplug My Laptop

There are a few different reasons why your FPS might drop when you unplug your laptop, lets’s take a look!

1. Lack Of Power 

First, it could be due to a lack of power. If your laptop is running low on juice, it won’t be able to perform at its best. 

This is especially true if you’re playing a graphically demanding game or working with resource-intensive applications. 

Possible Fix

To fix this issue, make sure you’re your battery reserves are replenished by connecting your laptop to a power source.

2. Power Profile Mode

One of the most common reasons why your FPS might drop when you unplug your laptop is because of power mode. 

Windows by default have multiple profiles for power options. For example, when your laptop is plugged in, it will automatically switch to a “performance” power mode. 

This power mode is designed to give you the best possible performance by maxing out your CPU and GPU. However, when you unplug your laptop, it will automatically switch to a “battery saver” power mode.

In battery saver mode, your CPU and GPU are throttled to save power. This can lead to lower performance, as the CPU and GPU will be working at reduced speeds. 

In some cases, you might even see a noticeable difference in graphics quality. So if you’re noticing that your FPS drops when you unplug your laptop, it’s probably because it’s running in battery-saving mode.

Fix For Power Profile Mode

Luckily, there’s an easy fix for this problem. All you need to do is change your power settings so that your laptop doesn’t automatically switch to the battery-saving mode when it’s unplugged.

Here is how you can do it,

  • To do this, open the Windows Control Panel and go to.  Hardware and Sound>Power Options. 
  • On the left-hand side, you’ll see a list of different power plans. Find the one that says “Balanced” and click on it. 
  • Scroll down to the “Battery” section and expand it. 
  • Under “Battery saver settings”, you’ll see a setting for “When plugged in, turn off.” Make sure that this setting is turned off. 
  • This will prevent your computer from automatically switching to battery saver mode when it’s unplugged. As a result, your FPS should no longer drop when you unplug your laptop.

For Dedicated Graphics Card (AMD & Nvidia)

Moreover, you can also change the power settings for your dedicated GPU. If you have a discrete GPU (such as an NVIDIA or AMDGPU), you can usually find the power settings in the driver control panel. 

Nvidia Graphics Cards

For NVIDIA GPUs, open the NVIDIA Control Panel and go to “3D Settings”. Then, find the setting for “Power Management Mode” and set it to “Prefer Maximum Performance”. This will disable any power-saving features on your GPU and should help to improve your FPS.

AMD Graphics Card 

For AMD GPUs, open the Catalyst Control Center and go to “PowerPlay”. Then, set the “Battery” option to “Performance”, and set the “AC Power” option to “Maximum Performance”. This will disable any power-saving features on your GPU and should help to improve your FPS.

3. Thermal Throttling

Thermal throttling can also lead to FPS drops when you unplug your laptop. If your computer starts to overheat, it will throttle the CPU and GPU to prevent damage. 

It’s worth checking to see if the CPU and GPU are being throttled. To do this, open the Task Manager and go to the “Performance” tab. Then, look at the “CPU” and “GPU” graphs. If you see that either of them is being throttled, that’s likely the cause of your problem. 

Fix For Thermal Throttling

There are a few different ways to fix this problem. First, you can try cleaning out the dust from your laptop’s cooling system. This will help to improve airflow and keep your components cool. 

Invest In A Cooling Pad

You can also try using a laptop cooling pad. These devices help to improve airflow around your laptop and can prevent it from overheating. 

Undervolt Your Hardware

Finally, you can try Undervolting your CPU. This will reduce the amount of power it uses, which can help to keep your laptop cool and prevent throttling. 

4. Wi-Fi Connection

Another possible reason for FPS drops when you unplug your laptop is a weak Wi-Fi connection.

If you’re trying to play a game or work on a project that requires a lot of data, a weak Wi-Fi connection can lead to FPS drops and other performance issues.

This is because your computer will need to constantly send data back and forth between your router and the server, leading to increased latency and potential data loss. 

Fix Regarding WIFI Relating Issues

There are a few different ways to improve your Wi-Fi connection. First, you can try moving your router closer to your laptop. This will reduce the distance the data has to travel and can help to improve performance. 

You can also try using a wired Ethernet connection. This will provide a much more stable and reliable connection than Wi-Fi, so it’s worth trying if you’re having performance issues. 

Finally, you can try changing the channel that your router is using. In some cases, overcrowding on a particular channel can lead to slower speeds and increased latency. 

So if you’re having trouble with your Wi-Fi connection, it’s worth trying a different channel to see if that helps.

5. Out-Of-Date Drivers

Out-of-date drivers can lead to all sorts of performance issues, so it’s always a good idea to make sure they’re up to date. 

To check for updates, open the Device Manager and look for any devices with a yellow exclamation mark next to them. This indicates that there’s an update available for the device. 

You can also try using a driver updater tool. These tools will scan your system for out-of-date drivers and then install the latest versions automatically.

6. Performance Capped Due To BIOS Mode

When you start your computer, the BIOS (Basic Input/Output System) initializes all of your hardware and starts up your operating system. 

If your BIOS is set to “performance” mode, it will prioritize performance over power saving. However, if it’s set to “power saving” mode, it will prioritize power saving over performance. 

This can lead to lower framerates and overall performance issues. 

Fix For BIOS Performance Limiter

To fix this, you’ll need to change the setting in your BIOS. To do that, you’ll need to restart your computer and press a key during startup (usually F2 or DEL) to enter the BIOS menu. 

Once you’re in the BIOS menu, navigate to the “boot” or “startup” tab and look for an option that says “power-saving mode.” Change this setting to “disabled” and then save your changes. 

This will ensure that your computer is always running in performance mode, which should help to boost your FPS.
