If you have a Dell Inspiron 15 3000 Series Laptop and you want to upgrade it to Windows 11, you might be wondering how to make it run faster and smoother.

Windows 11 is a new operating system that has higher system requirements than Windows 10, so you might need to tweak some settings or upgrade some components to get the best performance out of your laptop.

In this article, we will show you some tips and tricks on how to speed up your Dell Inspiron 15 3000 Series Laptop for Windows 11, based on information from this YouTube video:

Tip #1: Check if your laptop meets the minimum requirements for Windows 11

Before you upgrade your laptop to Windows 11, you should check if it meets the minimum requirements for the new operating system. According to Microsoft, these are the minimum requirements for Windows 11:

  • Processor: 1 GHz or faster with two or more cores on a compatible 64-bit processor or system on a chip (SoC)
  • Memory: 4 GB of RAM
  • Storage: 64 GB or larger storage device
  • System firmware: UEFI, Secure Boot capable
  • TPM: Trusted Platform Module (TPM) version 2.0
  • Graphics card: Compatible with DirectX 12 or later with WDDM 2.0 driver
  • Display: High definition (720p) display that is greater than 9” diagonally, 8 bits per color channel
  • Internet connection: Microsoft account and internet connectivity are required for setup for Windows 11 Home

To check if your laptop meets these requirements, you can use the PC Health Check app from Microsoft, which will scan your device and tell you if it's compatible with Windows 11. You can download the app from here:

If your laptop does not meet the minimum requirements, you might not be able to upgrade to Windows 11, or you might experience poor performance and stability issues. In that case, you might want to consider upgrading some of the components of your laptop, such as the processor, memory, storage, or graphics card. However, keep in mind that not all components are easily replaceable or upgradable on laptops, especially on budget models like the Dell Inspiron 15 3000 Series. You might need to consult a professional technician or contact Dell support for more information on how to upgrade your laptop.

Tip #2: Upgrade your storage device to an SSD

One of the most effective ways to speed up your laptop is to upgrade your storage device from a hard disk drive (HDD) to a solid state drive (SSD). An SSD is much faster than an HDD in terms of reading and writing data, which means it can load applications and files much quicker and improve the overall responsiveness of your laptop. An SSD also consumes less power and generates less heat and noise than an HDD, which can extend the battery life and reduce the fan noise of your laptop.

The Dell Inspiron 15 3000 Series Laptop comes with either an HDD or an SSD, depending on the configuration you choose. If you have an HDD, you might want to replace it with an SSD to boost the performance of your laptop. To do this, you will need to open up your laptop and remove the HDD and install the SSD in its place. You will also need to clone your existing data from the HDD to the SSD using cloning software or backup and restore software. Alternatively, you can reinstall Windows 11 on the SSD from scratch using a bootable USB drive.

Tip #3: Increase your RAM

Another way to speed up your laptop is to increase your RAM (random access memory), which is the temporary storage space that your laptop uses to run multiple applications and tasks at the same time. The more RAM you have, the more programs you can run simultaneously without slowing down your laptop. RAM also affects how fast your laptop can switch between different applications and tabs, which can improve your multitasking efficiency.

The Dell Inspiron 15 3000 Series Laptop comes with either 4 GB or 8 GB of RAM, depending on the configuration you choose. If you have only 4 GB of RAM, you might want to upgrade it to at least 8 GB or more to meet the recommended requirements for Windows 11 and run more applications smoothly. To do this, you will need to open up your laptop and remove the existing RAM module and install a new one with a higher capacity in its place. You will also need to make sure that the new RAM module is compatible with your laptop's motherboard and processor.

Tip #4: Adjust your power settings

Another simple way to speed up your laptop is to adjust your power settings, which affect how much power your laptop consumes and how fast it runs. By default, Windows 11 has three power modes: Battery saver, Recommended, and Performance. You can switch between these modes by clicking on the battery icon in the taskbar and moving the slider.

Battery saver mode reduces the brightness of your screen and limits the background activity of your laptop to conserve battery life. This mode is suitable for when you are away from a power outlet and need to extend the battery life of your laptop as much as possible. However, this mode also reduces the performance of your laptop and makes it run slower.

Recommended mode balances the performance and battery life of your laptop according to your usage patterns and preferences. This mode is suitable for most situations when you are using your laptop normally.

Performance mode boosts the performance of your laptop by increasing the CPU speed and allowing more background activity. This mode is suitable for when you need maximum performance from your laptop for demanding tasks like gaming or video editing. However, this mode also consumes more power and drains the battery faster.

To speed up your laptop, you might want to switch to Performance mode when you are plugged into a power outlet and need more speed from your laptop. However, keep in mind that this mode will also generate more heat and noise from your laptop's fan, so make sure that your laptop has adequate ventilation and cooling.

Tip #5: Disable unnecessary startup programs

Another easy way to speed up your laptop is to disable unnecessary startup programs, which are applications that run automatically when you turn on your laptop. Some of these programs are essential for the proper functioning of your laptop, such as antivirus software or drivers. However, some of these programs are optional or unwanted, such as third-party software or bloatware that came preinstalled on your laptop. These programs can slow down your laptop's boot time and consume valuable resources in the background.

To disable unnecessary startup programs on Windows 11, follow these steps:

  • Right-click on the Start button and select Task Manager.
  • Click on More details if necessary.
  • Click on the Startup tab.
  • You will see a list of programs that run at startup along with their status (enabled or disabled) and their impact (high, medium, low) on startup time.
  • To disable a program from running at startup, right-click on it and select Disable.
  • Repeat this process for any program that you don't need or want at startup.
  • Close Task Manager and restart your laptop.

By disabling unnecessary startup programs, you can speed up your laptop's boot time and free up some resources for other tasks.


These are some of the tips and tricks on how to speed up a Dell Inspiron 15 3000 Series Laptop for Windows 11. By following these steps, you can improve the performance and responsiveness of your laptop and enjoy a smoother experience with Windows 11. However, keep in mind that these tips are not guaranteed to work for every situation or configuration of laptops. You might need to experiment with different settings or components to find what works best for you.
