Getting service tag / bios info using powershell

Following on from my post “script to get service tag from dell device” I felt a bit “dirty” that I was using VB opposed to my new favourite thing in the world, powershell!

You can use a cmdlet “get-wmiobject” to pull all sorts of info from WMI, including the bios.

Therefore, this very simple one liner will return not only the service tag (or serial number for non dell devices), but bois version and a raft of other information.
Here is the command

Get-wmiobject win32_bios | fl *

The result will look something like this

If you have WinRM remoting configured, you can run this on a remote device by starting an interactive session, and then running the command

PS> enter-pssession servername
Server name: PS > get-wmiobject win32_bios | fl*

If you don’t have WinRM remoting enabled, run this command on the host to enable it.

PS > winrm quickconfig
