Invalid Serial Number Hp Bios

Active5 months ago

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..

The message shows that the serial number is not entered, or entered incorrectly, after replacing the system board or other component information manually, the problem solves.

  1. Yes, I can do that in the BIOS and it saves it fine. For some reason any other utility for online checks (HP Support Advisor and HP Auto Identify) still report the invalid Serial number.
  2. Fix Missing Serial/Product Numbers for HP Laptops. Well i have the problem invalid serial number on probook 4515s and i cant boot because i take only blanc screen.

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).

Troubleshooting

Tried:

Get-WmiObject Win32_ComputerSystem Select-Object OEMStringArray

Result:

{ABS 70/71 79 7A 7B 7C, CMS v01.4A, HP_Mute_LED_0, www.hp.com}

.. But expecting to find XT908UT#ABA

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).

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.
