How to Use the Toshiba PC Diagnostic Tool: Step-by-Step Guide

Download and Install the Toshiba PC Diagnostic Tool: Quick Guide

This quick guide shows how to download, install, and run the Toshiba PC Diagnostic Tool on a Windows PC (assumes Windows ⁄₁₁).

1) Before you start

• Back up any important data.
• Ensure your laptop is plugged in (battery tests may run).
• Windows account: you’ll need an administrator account to install.

2) Download the tool

1. Open your browser and go to the official support page for your Toshiba/Dynabook model (support.dynabook.com or the Toshiba support site).
2. On the model’s Downloads/Drivers page, look for “PC Diagnostic Tool” or “TOSHIBA PC Diagnostic Tool Utility.”
3. Download the installer that matches your OS (32-bit or 64-bit if offered). If the tool came preinstalled on your system, the support page will note that instead.

Note: If official model-specific download isn’t available, Dynabook’s support site hosts the TOSHIBA PC Diagnostic Tool utility documentation and installers.

3) Install the tool

1. Locate the downloaded file (usually in Downloads).
2. Right-click the installer and choose Run as administrator.
3. Follow the on-screen prompts:
   • Accept the license/EULA.
   • Install any required companion packages (some Toshiba utilities require a “Value Added Package” installed first — install it if prompted).
4. Restart the computer if the installer requests it.

4) Run diagnostics

1. Open Start and type Diagnostic (or open the TOSHIBA folder in the Start menu).
2. Launch PC Diagnostic Tool. The app shows basic system info on launch.
3. Go to the Diagnostic Tool tab.
4. Select the components you want to test (battery, memory, storage, sensors, connectivity, etc.).
5. Click Start Diagnostic.
6. Read results — tests typically report Pass or Fail. Use the tool’s Help for component-specific guidance.

5) Interpreting results & next steps

• Pass: component appears functional.
• Fail: note error details and model/serial number, then contact Dynabook/Toshiba support or a qualified technician. For failing storage or memory, back up data immediately.

6) Troubleshooting installation or running issues

• Install the latest Windows updates and restart.
• Run the installer as administrator.
• Temporarily disable third-party antivirus if it blocks installation (re-enable afterward).
• If the tool won’t run on your model/OS, use manufacturer support pages or contact support for the correct diagnostic package.

7) Additional diagnostic tools (if needed)

• Windows Memory Diagnostic (built into Windows).
• chkdsk and S.M.A.R.T. tools for drives.
• Manufacturer storage diagnostic tools (Toshiba Storage Diagnostic Tool for HDD/SSD).
