If your Toshiba laptop starts to act up: it starts to run slow, hang up more often, or crash randomly, etc; You'd better watch out. Because the situation may get worse if you leave it alone. Plus, a slow computer may affect your health according to new research.

It doesn't matter whether you are using an old Toshiba Satellite or a brand new one, the machine will run slower over time. Similar to a car, without proper maintenance, its life will end much earlier.

In this guide, we're going to share with you solutions to tackle different types of computer performance issues. Hopefully you'll figure out the reasons why your Toshiba laptop is running slow or freezing, and more importantly get them fixed.

Note: this guide is made to tune up Toshiba laptops (Satellite, Portege, T-series, C-series, A-series, etc) that run with  Microsoft Windows (7, 8, 10) operating system that can boot up normally. If it won't start up, call Toshiba support immediately and take your computer for further technical 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. Now 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, and sometimes it shuts down unexpectedly.

Possible causes:

  • Your 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, etc) at once, using lots of system resources.
  • You are playing games with external console connected, and your Toshiba laptop's hardware is not advanced enough.


  • Clean the heatsink. See the video tutorial (below).
  • Buy a laptop cooling mat or pad.
  • If your laptop is quite old, avoid running several programs at once. Using it for gaming is not recommended either.

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:

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

How to optimize:

Issue 4: Toshiba Laptop Slow While Browsing 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. In this case, web page loading performance has nothing to do with your laptop system.
  • The webpages you are browsing contains Adware — lots of flash ads, consuming lots of system resources like CPU, memory.
  • Your open too many tabs or windows at the same time.
  • Your web browser is loaded with plugins, extensions.
  • You are using a lower-version or slow web browser. Beware that some web browsers use more resources than others.

How to speed up:

  • Check the internet access speed with your internet provider (you can use, it's free). If you are connected via Wi-Fi, move to a spot closer to the router.
  • Run Plumbytes Anti-Malware to check and get rid of Adware plugins or services.
  • Optimize your web browsing habit: close those pages you no longer need to view.
  • Remove or disable plugins you don't use. You can get this done easily with CleanMyPC (via the "Extensions Manager" feature).
  • Use a modern browser such as Google Chrome, 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 from time to time; 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 issue, especially those applications tend to require more resources (RAM, CPU) to run smoothly.
  • Device driver issues. Drivers are the bridges for hardware to communicate with operating system, if they get corrupted or dated, the computer system can freeze.
  • Cluttered system registry errors.
  • Your Toshiba laptop's specifications are lower than optimal for running with current Windows operating system.
  • Computer viruses.


  • Refer back to "Issue 2" for how to solve overheating problems.
  • Make sure all your third-party programs are up to date. Also try to avoid multitasking — opening several programs at once.
  • Use Driver Navigator to update all hardware device drivers to most current version, and uninstall problematic drivers.
  • Run CleanMyPC (the "Registry Maintenance" feature) to detect and fix all windows registry errors.
  • Downgrade to a lower Windows OS. Here is a tutorial on how to go back to Windows 7 or 8 from latest Windows 10.
  • Once again, run spyware check on a regular basis.

Issue 6: Toshiba Laptop Runs Slow In General

Symptoms: your laptop is still slow and glitchy, and 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 hard drive. You can either do this manually or use CleanMyPC to save time. Either way, you should start with those folders where large, duplicated items exist, transfer or remove them. Also, don't forget to uninstall programs you don't usually use.
  • Upgrade hardware. If you prefer a cheaper way, add more RAM; If you can afford an SSD, go ahead and order one from Amazon or, the investment will boost your Toshiba laptop and take the performance to a new level. However, a decent SSD can cost you a couple of hundred bucks.

Final Words

It can be very frustrating to see a normal laptop starts to run slow or suffer other issues. Due to the nature of technology — everything's got a lifespan, it's sometimes inevitable to see such programs keep occurring. However, if you take good care of your Toshiba laptop — have good using habits, spend some time or money on maintenance, it can still run strong and does its job to serve your computing needs.
