How to determine the serial number of an HP laptop

This article explains how to find the serial number of an HP laptop.

 

Where is your serial number located?

To find the serial number, the first place to look is on the bottom of the laptop. The serial number is usually printed on a label along with the product number, model number, and warranty period. If you don't see a label, it's probably inside the battery compartment.

How to Use Command Prompt to Find HP Laptop Serial Number

If the label is damaged or peeled off, another way to get the serial number is through the computer itself. As long as the laptop is still working, you can also get the serial number using Command Prompt .

Open Command Prompt by searching from the Start menu.

Type this command into Command Prompt, then press Enter to execute the command:

wmic bios get serialnumber

Your serial number will appear after the command. To copy the serial number, highlight the serial number with your mouse and then right-click anywhere in the Command Prompt.

 

Where else can you find the serial number?

The serial number is also located in the System Information window of your HP laptop. To open this window, type Fn + Esc .

A system information tool is another way to determine the serial number. These tools are useful if you need the serial number for specific components, such as a hard drive or RAM .

When do you need your HP laptop serial number?

The serial number identifies your specific HP product, taking the guesswork out of troubleshooting by determining when your laptop was manufactured and what hardware was used.

If you contact customer support to troubleshoot a problem, they will ask for the serial number. You can also use the serial number to check the warranty status of your laptop. Whether or not your device is still under warranty, you will need to provide the serial number if you send your laptop in for repair.

Check HP laptop age by serial number

Even after your laptop's warranty has expired, you can still use the serial number to see how old your laptop is.

You can determine the production date of your laptop by looking at the 4th, 5th, and 6th digits in the serial number. The 4th digit is the last day of the year and the next two digits indicate the week. The number 050 would indicate that the laptop was manufactured in the 50th week of 2020.

What is the serial number?

A serial number is a series of numbers and letters that identifies your specific HP device. A laptop series, like the HP Envy, will have a product or model number that matches other laptops manufactured at the same time, but the serial number is unique to each individual laptop.
