Get Dell Service Tag using PowerShell

by Bharat Suneja

A popular script on this blog uses the Win32_SystemEnclosure WMI class to get the Dell Service Tag from Dell computers [see Getting Dell Service Tag using WMI].

Powershell’s Get-WmiObject cmdlet makes it a one-liner. You can also use it to get the serial number from systems made by other manufacturers.:

Get-WmiObject win32_SystemEnclosure | select serialnumber

To list all properties exposed by the Win32_SystemEnclosure class:

Get-WmiObject win32_SystemEnclosure | fl *

Update 7/13/2022:

As @Ripstone commented, Get-WmiObject is superseded by the new Get-CimInstance cmdlet based on the Common Information Model (CIM). You can use it to get the same Win32_SystemEnclosure class and the Dell Service Tag or serial number.

Get-CimInstance win32_SystemEnclosure | select serialnumber

Seems like the following works too:

Get-WMIObject -Class Win32_Bios

Added advantage is it works on my IBM Blades too whereas the other does not…

Dell has been remarkably open to date in allowing users to publicly vent their spleen on its blog.

Hi,
Does this also works for HP Server ?

So how do you get the serial without all of the extra text. I have thus far:

gwmi win32_bios | select serialnumber

But that returns:

serialnumber
——————-
[The actual serial number]

How can I omit the first two lines being returned?

“How can I omit the first two lines being returned?”

You want to use the “-expand” flag for Select-Object. Try this:
gwmi win32_bios | select -expand serialnumber

How can you get the service tags for multiple servers at the same time?
Thanks,

WMI has been deprecated since PowerShell v3. This command should work going forward:

Get-CimInstance win32_SystemEnclosure | select serialnumber
