Why Is My Lenovo Laptop So Slow? (SOLVED)

Why Is My Lenovo Laptop So Slow

Are you wondering why is my Lenovo laptop so slow? I have experienced many slow laptops and PCs and found the best ways to optimize them for fast performance.

Why Is My Lenovo Laptop So Slow?

Your Lenovo laptop is slow because of a few possible reasons:

  • Your laptop or the components are old
  • You have not optimized Windows for a long time
  • Your laptop has a lot of dust build up inside the case
  • You are running too many programs at once
  • You are trying to run programs that are too intensive for your hardware

How To Fix A Slow Lenovo Laptop

Here are the best ways I have found that can improve your Lenovo laptop speed.

Restart your PC if required at the end of the process.

Release Disk Space

Freeing up disk space is a great way to improve your system’s performance.

The best way to do this is to go to control panel > uninstall a program.

Then uninstall all the uneeded apps you have. If this is too much for you then you can download a system cleanup program which will automatically scan and clean up all the files that need it.

Delete Temporary Files

Your Lenovo laptop will store a lot of temporary files over time which can cause your laptop to slow down. These files have no real use and can be deleted to give you a speed boost.

To delete any temporary files do the following:

  • Press Windows key + R to bring up the run menu
  • Type in %temp% then press ok
  • Press Ctrl + A to select all and then right click and delete.
  • Press Windows key + R again to bring up the run menu
  • This time just type temp and press enter.
  • Press continue to the prompt
  • Press Ctrl + A to select all and then right click and delete.

Now to delete the prefetch temp files:

  • Press Windows key + R to bring up the run menu
  • type prefetch and press ok
  • Press continue to the prompt
  • Press Ctrl + A to select all and then right click and delete.

Fix Power Options

Power options can significantly affect your laptop’s performance. Having it set to the wrong setting can slow down your Lenovo laptop without you even knowing. Here are the best settings for power options to have fast speed:

  • Go to windows search and type power. Click on Power & sleep settings
  • Click on additional power settings
  • Now select high performance.

You may need to check a box that allows you to switch to the high performance setting on this page.

Disable unecessary services

Disabling unecessary services is another great way to improve your laptop’s performance. This is very easy all you need to do is:

  • Press Windows key + R to bring up the run menu
  • type services.msc and press ok
  • In the window that pops up click on the services tab.
  • Then check hide all Microsoft services.
  • Then click disable all or select the ones you don’t want and press apply.
  • Restart your PC.

Tune System Performance

Did you know there are settings in Windows that can adjust your laptop for the best performance? These settings will make small visual changes on your laptop which will increase your performance.

You can find these settings by:

  • Searching System in windows search
  • Clicking on system and then clicking advanced system settings.
  • Check the Adjust for best performance option.
  • Then check “Show shadows under the mouse pointer” and “Show shadows under windows.”
  • Click OK then OK again.

Another thing you can do is inside regedit. The method includes changing some values which will make your Windows performance better.

To do this:

  • Type in Regedit into windows search
  • Click on registry editor.
  • Expand HKEY_CURRENT_USER and expand control panel
  • Click on mouse and then double click on MouseHoverTime
  • Change the value to 10 and press OK.
  • Click on the desktop folder and double click on MenuShowDelay
  • Change the value to 10 and press OK.

Scan for Malware

Malware can really slow down your laptop, especially if you have a virus which is using your laptop’s components like a bitcoin miner.

Viruses can slow down your PC entirely and the best way to get rid of them is to use malwarebytes which is a free software you can download to remove malware from your laptop.

Make sure to scan your laptop once a month and do a deep scan because basic scans might not pick up the viruses.

Restore Your Lenovo Laptop

If nothing is working for you and you want a fresh install of windows you can always restore your Lenovo laptop. This will definitely give you a huge performance boost and is necessary if your laptop is very old.

You can restore your laptop while keeping your files but I suggest that you backup your files anyway.

If you want to know how to factory reset your Lenovo laptop then you can read my article about it.

Disconnect All External Devices and Restart

External devices can slow down your laptop often times because they are using your laptop as a charging station.

It’s best if you disconnect anything that is connected to your laptop and see if the issue has resolved itself or not.

Optimize Windows 10 Startup

If you have a lot of programs on Windows, chances are you also have a lot of startup programs which are constantly running in the background and slowing down your Lenovo laptop.

If you want the best performance then you should disable as many startup programs as you can. To do this simply:

  • Right click on the Windows start menu and click on task manager. Or press CTRL + ALT + DELETE and select task manager.
  • Then click on the startup tab.
  • Then click on unimportant startup programs and press disable.

Clean up the Hard Drive

Disk cleanups are a great way to improve your laptop performance and are quite easy to do. It’s recommended that you do a disk cleanup every once in a while to keep your hard drive fresh.

You can do a disk cleanup by:

  • Typing disk cleanup into windows search and choosing disk cleanup from the list.
  • Then you can slect all the unecessary files and folders you want deleted and press clean up system files.

Defragment the Hard Drive

Hard drives can really slow down your laptop, especially if they are over a year old. The hard drive is what stores and runs all your files. Having old hard drives that are nearly full of files can really slow down your operating system.

It’s a good idea to defragment your hard drive after a while because every time you delete files they get overwritten with new files and this can cause all sorts of performance problems if you never defragment.

To defragment your hard drive and improve the performance do the following:

  • Click on windows start and search defragment.
  • Click on defragment and optimize
  • Click on C drive and click optimize
  • Click close.

Upgrade the RAM

A second RAM stick can be added to some Lenovo laptops. There are some laptops that don’t have a free ram stick slot or removable ram, but if you have one, you should make use of it.

If you only have 4GB of RAM, you should think about adding another stick or upgrading both of the existing ones since your laptop needs at least 8GB of RAM.

If you don’t exactly match the model of RAM stick you already have, it won’t work. To find out what model you have, check online or in your laptop manual. Additionally, make sure the capacity and hz of the RAM sticks you purchase match.

Here is how you can upgrade or change ram on your Lenovo laptop:

  • Power off your laptop and open the case.
  • Look for access to the ram sticks.
  • Unscrew any panels to access the ram sticks and press any levers to dislodge them.
  • Insert new ram into the slots
  • Replace any panels and screw on the back panel of your laptop.
  • Turn on your laptop.

Health Check Your Lenovo Laptop

There are several programs that you can download which will health check your laptop and show any issues. Programs like bitdefender are great at this.

They also have virus scanning and system optimisation functionality. I also recommend using CCleaner to cleaunp all your system files and give your laptop a big boost in performance.

Disable Hardware Acceleration

A setting for hardware acceleration may be found in various applications, most notably Discord and Spotify. This option may occasionally be set to default. Hardware acceleration seems fantastic, but if you have such apps operating in the background, it really reduces your speed.

When hardware acceleration is enabled, the software will run more quickly and put greater strain on your CPU.

Here are where you can find the settings:

Discord: settings -> APP -> Appearance
Spotify: settings -> Advanced

Update Graphics Card Drivers

Checking for any recently installed graphics upgrades that you might have overlooked is one of the finest things you can do if your PC starts acting unexpectedly underwhelming. Make careful to stay current because NVIDIA routinely pushes GPU upgrades.

Increasing FPS in games and avoiding black screens or crashes may both be accomplished by updating graphics and drivers.

Disable Core Parking

Disabling core parking is another detail to get better performance from your CPU.

To do this simply:

Open start menu, search regedit
Press edit -> find. Then paste this key in: 0cc5b647-c1df-4637-891a-dec35c318583
Select keys and press find.
Now you wil lsee a new screen. Find ValueMax, edit it and set it to 0 hexadecimal. It should be on 64 by default.
Now you will have disabled parking of your cores and should have more performance.

Clean Your PC

This is unimportant if you use a laptop, but you should clean your desktop computer if you do.

Your PC case will fill up with a lot of dust over time, which can block all of your fans. Additionally, it will cause your PC to retain a lot of heat, which lowers performance.

PC cleaning is simple. Then, either use bottled air to blow away the dust or just clean the fans with your fingers after turning off and unplugging your computer and unscrewing the casing. Be cautious not to harm the motherboard by touching any of its components.

Symptoms Of A Slow Laptop

The symptoms of a slow laptop are the following:

  • Your laptop takes an unsually long time to boot up.
  • You see the spinning blue wheel a lot.
  • Programs take a very long time to load
  • You get low FPS in video games
  • It takes a long time to close programs
  • Programs become unresponsive a lot


Lenovo laptops are no different from other slow laptops in this regard.

You will need to use a few of the useful suggestions I have offered in this article to optimise your laptop for the best performance in order to achieve this.
