How to Fix Toshiba Laptop Running Slow or Freezing

If your Toshiba laptop starts to act up: runs slow on Windows 10/11, hangs up more often, or keeps freezing and not responding, etc; You’d better watch out. Because the situation could get worse.

It doesn’t matter whether you use an old Toshiba Satellite or a brand-new one, your PC will run slower over time. Similar to a car, without proper maintenance, its lifespan can be discounted quickly.

In this article, we are going to share some common performance issues and relevant fixes for a slow Toshiba laptop. Hopefully, you’ll be able to turn it up.

Note: the guide is made to tune up Toshiba laptops (Satellite, Portege, T-series, C-series, A-series, etc) with Microsoft Windows 7, 8, 10, 11 operating system that can boot up normally. If it won’t start up, call Toshiba support immediately and let them take your computer for further diagnosis.

Issue 1: Toshiba Laptop Mouse Frozen

Symptoms: the laptop touchpad or external USB mouse cursor randomly freezes, and the cursor doesn’t respond when you try to move it around.

How to unfreeze:

  • Step 1: test if the touchpad is enabled. Press “Fn” + “F9” keys at the same time (for some Toshiba models, try “F5” alone instead). This keyboard shortcut is designed to enable or disable the touchpad software. See if it works.
  • Step 2: if step 1 doesn’t work out. Now shut down your computer, remove the power cord, flip over your laptop and remove the battery, then put the battery back and plug in the power cable, turn on your Toshiba. This should make it work.

Issue 2: Toshiba Laptop Overheating

Symptoms: your laptop heats up very quickly with loud fan noise, sometimes it shuts down unexpectedly.

Possible causes:

  • The heatsink’s radiator is dusty and is unable to properly cool down the CPU.
  • Your laptop is exposed to an environment with high temperature.
  • You are running multiple heavy programs (Adobe Photoshop, video editing tools, etc) at once, using lots of system resources.
  • You are playing video games with external consoles connected.


  • Clean the heatsink. See the video tutorial (below).
  • Buy a laptop cooling mat or pad.
  • Avoid running several programs at once.
  • Using your laptop for gaming is not recommended.

Issue 3: Toshiba Laptop Slow On Startup

Symptoms: your laptop takes much longer to fully start up or launch to the first screen. Even worse, it freezes on startup and you have to give it a hard reboot.

Possible causes:

  • There are too many auto startup items.
  • Windows is installing new updates.
  • Your computer is infected with malware.

How to optimize:

  • Disable programs and services automatically run on startup.
  • Change Windows Update settings to avoid auto-update, see how to do it here.
  • Run a malware scan and get rid of any malicious Adware and spyware it might find.

Issue 4: Toshiba Laptop Slow on the Internet

Symptoms: your web browser (IE, Chrome, Firefox, etc) is super slow to load web pages. Sometimes it just hangs and becomes unresponsive. In rare situations, the browser crashes.

Possible causes:

  • Your Internet connection is slow or weak. Web page loading performance has nothing to do with your laptop system.
  • The web pages you browse contain Adware — lots of flash ads, consuming lots of system resources.
  • You’ve opened too many tabs or windows at once.
  • Your web browser is loaded with plugins, and extensions.
  • You are using a lower-version or slow web browser. Beware that some web browsers use more resources than others.

How to speed it up:

  • Check the internet access speed with your internet provider (you can use, it’s free). If you are connected via Wi-Fi, move your laptop to a spot closer to the router.
  • Run an antivirus program to check and get rid of Adware plugins or services.
  • Have a better web browsing habit: close those pages you no longer need to view.
  • Remove or disable plugins you don’t use.
  • Use a modern browser such as Google Chrome, or Firefox, and make sure it’s up to date.

Issue 5: Toshiba Laptop Keeps Freezing

Symptoms: your laptop freezes every 5 or 10 minutes, or it freezes randomly; When that happens, it either comes with a page delay or becomes totally unresponsive — and you have to force quit the browser or restart your computer.

Possible causes:

  • Overheating, as introduced in the “Issue 2” section.
  • Third-party software issues, especially those applications that demand more resources to run.
  • Device driver issues. Drivers are the bridges for hardware to communicate with the OS, if they get corrupted or dated, the computer system can freeze.
  • Cluttered system registry errors.
  • Your laptop’s specifications are lower than optimal for running the latest Windows 10.
  • Computer viruses.


  • See “Issue 2” above for how to solve overheating problems.
  • Make sure all your programs are up to date. Also, try to avoid opening several applications at once.
  • Downgrade to a lower Windows OS.

Issue 6: Toshiba Laptop Runs Slow in General

Symptoms: your laptop is still slow and glitchy, even if you’ve applied some of the solutions above.

Possible causes:

  • Too many external devices (e.g., printer, USB, camera card, etc) are connected.
  • Your hard drive is almost full.
  • Lack of memory (RAM).
  • Aging, failing hard disk drive (HDD).

How to fix:

  • Unburden your Toshiba by unplugging those peripheral devices.
  • Clean up the hard drive. You can also do this manually, e.g. start with those folders where large, duplicated items exist, transfer or remove them. Also, uninstall unused programs.
  • Upgrade hardware. Adding extra RAM is you often use your Toshiba laptop for photo/video editing; If you can afford an SSD, do that and the investment will boost your Toshiba laptop and take the performance to a new level.

Final Words

It can be very frustrating to see a normal Toshiba laptop start to run slow or suffer other issues. Due to the nature of technology — every tech (old and new) has a lifespan, it’s sometimes inevitable to encounter performance issues.

However, if you take good care of your Toshiba laptop — have good user habits, and spend some time or money on maintenance, it can still run strong and does its job to serve your computing needs.
