If your business requires you to be on the move frequently, chances are you rely heavily on your HP laptop. Over time and with plenty of wear and tear, your model might require adjustment or repair. To expedite your repair work and locate the replacement parts required, the manufacturer may request your model number. Depending on which model you own, your model number can be found using several different methods.

On the Underside of the Laptop

On most HP models, the sticker on the underside of the laptop contains your model number, along with other important information. Turn your laptop upside down and place it on a soft, clean surface such as a chair or couch cushion. Locate the white or silver sticker on the underside of the laptop, toward the middle of the casing. Read the sticker and look for the prefix 'P/N.' The number following this prefix is your computer's model number.

On the Inside of the Battery Compartment

If the sticker on the underside of the laptop has been scratched off or purposefully removed, another place to check is inside the battery compartment. Turn the laptop upside down and locate the battery compartment near the screen hinge. Depress the lever to unlock the battery and lift it gently upward to remove it. Look for a white or silver rectangular sticker, either on the battery or in the compartment. Locate the 'P/N' prefix and record the number that follows it.

Beneath the Laptop's Bottom Casing

If you can't locate the model number on the battery or on the bottom of the computer, you may need to remove the casing on the underside of the laptop to find it. Ensure that the laptop is powered off and the battery is removed. With a small Phillips-head screwdriver, remove all of the perimeter screws from the casing. Place the screws in a secure location and gently lift up the casing. Near the left corner of the laptop, you'll see a square of information and specifications. Locate the 'P/N' prefix and record the number that follows. Replace the casing and re-install the screws.

Using System Information

Another way to locate the model of your HP laptop is by using the System Information screen. Press 'FN-Esc' to open the HP System Information window. A lot of information will be displayed within this window, but all you'll need to look for is the 'Product Number' heading. The number will contain the '#' symbol and is slightly different from a model number, but it will still provide all of the necessary information to the manufacturer or repair service.

Using HP Support Assistant

If you have the HP Support Assistant software installed, you can use it to quickly find your computer's model number. Click the Windows 'Start' button and type 'HP' in the Search field. Choose 'HP Support Assistant' from the displayed results. Your model number and other information will be displayed along the bottom edge of the Support Assistant window.

I have put together a robust HP Warrant Lookup PowerShell script. However, I cannot figure out how to get a HP system's product number in an automated process. So...

How can I get HP product number (not the serial number) via PowerShell? Although I would like to do with only built-in out-of-the-box Windows and PowerShell commands, I am open to other ideas. In the end, the ultimate goal is retrieve the product number in the most reliable and least invasive way possible (i.e. installing 3rd software).

Tried:

Get-WmiObject Win32_ComputerSystem Select-Object OEMStringArray

... But expecting to find XT908UT#ABA

Here are some methods that work for various computer models.

Method 1 : Registry

The HP product number is in the registry so can be retrieved in PowerShellHKEY_LOCAL_MACHINEHARDWAREDESCRIPTIONSystemBIOSitem SystemSKU.

More information and script can be found in the article :
How to: Find the HP Product Number of all your HP server using powershell.

Method 2 : rootwmi – MS_SystemInformation

Class MS_SystemInformation contains the product number in its member SystemSKU.
(Presumably it gets it from the registry as in the first method.)

For more info see Richard Siddaway's Blog.

Method 3 : Class Win32_BIOS

The following fragment finds the product number for some computer makes. Tested on Dell.

The Microsoft reference information is found in the article Win32_BIOS class.

This is tested on a HP Laptop. I think HP 'Product number' is called SystemSKUNumber in win32_computersystem WMI. Tested on my HP laptop.

Will result in:

If anyone else comes across this question, be advised, the entirety of win32_computersystem doesn't appear to contain the product number for servers, specifically. I was unable to actually find the information via WMI, but it turns out I was actually given the product number AND serial numbers for a number of servers (the spreadsheet was horribly formatted, so the two fields just looked like one big string until my afternoon coffee kicked in).

Works on Windows 7 & Windows 10From another user that posted. @harrymc

or try

$Server can be directly replaced by a ComputerName. example...

Keep in mind if you are on a domain you may need to provide credentials by either using an invoke-command or -credential parameter.

or

if WinRm is not configured on client, you may experience issues.
