Using Command Prompt to Find the Product Number
The command prompt is a powerful tool built into Windows that allows you to interact with your operating system through text-based commands. Luckily, we can leverage the command prompt to retrieve the product number directly from the system’s BIOS (Basic Input/Output System). The BIOS stores essential information about your laptop’s hardware, including the product number.
Step-by-Step Guide to Accessing Product Number via Command Prompt
The process involves opening the command prompt and executing a simple command. Here’s a detailed breakdown:
-
Open Command Prompt as Administrator: This is crucial because you need administrative privileges to access the necessary system information.
- Type “cmd” or “command prompt” in the Windows search bar.
- Right-click on “Command Prompt” in the search results.
- Select “Run as administrator.”
- A User Account Control (UAC) prompt might appear. Click “Yes” to proceed.
-
Execute the WMIC Command: The Windows Management Instrumentation Command-line (WMIC) is a command-line interface for WMI (Windows Management Instrumentation). WMI provides information about the system’s hardware and software. We can use WMIC to query the BIOS and retrieve the product number.
- In the command prompt window, type the following command exactly:
wmic bios get serialnumber- Press Enter.
-
Interpret the Output: The command prompt will display the output, which includes a label “SerialNumber” followed by your HP laptop’s product number.
- The displayed number is your product number. Copy it and store it in a safe place.
-
Alternative WMIC Command (If the First Fails): In some cases, the first WMIC command might not return the product number. This could be due to BIOS settings or system configurations. Try this alternative command:
wmic csproduct get identifyingnumber-
Press Enter.
-
This command retrieves the “IdentifyingNumber” of the computer system product, which is often the same as the product number.
-
-
Dealing with “Access Denied” Error: If you encounter an “Access Denied” error while running the command, it means you didn’t run the command prompt as an administrator. Close the command prompt window and repeat step 1, ensuring you select “Run as administrator.”
Understanding the Command and Its Components
Let’s break down the command wmic bios get serialnumber to understand what it does:
wmic: This is the command-line interface for Windows Management Instrumentation. It allows you to manage and retrieve information about your system.bios: This specifies that we want to access information from the BIOS (Basic Input/Output System). The BIOS is a firmware embedded on a chip on the motherboard that initializes hardware during the boot process.get: This instructs WMIC to retrieve a specific property from the BIOS.serialnumber: This is the specific property we want to retrieve, which represents the product number of the HP laptop. Note that HP saves the product number as SerialNumber.
Similarly, for the command wmic csproduct get identifyingnumber:
csproduct: This refers to the computer system product class in WMI.identifyingnumber: This is the property that stores the product’s identifying number, which is often the same as the product number.
Troubleshooting Command Prompt Issues
While using the command prompt is generally straightforward, you might encounter some issues. Here’s how to troubleshoot common problems:
