Computer Rename using Win32_Baseboard Serial number

[Mark]

Hey All,

I am new to powershell and I am trying to rename my Windows 7 laptop using
powershell. I have the following script and it's not working. Does anyone
know where I am going wrong? I wish to rename the computer using the
SerialNumber from W32_Baseboard.

Function Rename-ComputerName ([string]$NewComputerName){

$ComputerName = Get-WmiObject -Class Win32_BaseBoard | select SerialNumber
$ComputerInfo = Get-WmiObject -Class Win32_computersystem
$ComputerInfo.rename("$ComputerName")

}
Restart-Computer

Thanks in advance.

Regards,

Mark

Hi Mark,

don't have a change to try it, however can you try following?

Function Rename-ComputerName ([string]$NewComputerName){

[String]$ComputerName = Get-WmiObject -Class Win32_BaseBoard | select

SerialNumber
$ComputerInfo = Get-WmiObject -Class Win32_computersystem
$ComputerInfo.rename("$ComputerName")

}
Restart-Computer

One thing to check is that the serial number is actually returned on your
machine. On my laptop it isn't returned

PS> Get-WmiObject -Class Win32_BaseBoard

Manufacturer : Wistron
Model :
Name : Base Board
SerialNumber :
SKU :
Product : 303C

Mark,

Try going after - Win32_BIOS | Select SerialNumber

Thanks. It doesnt work. If I try the Rename-ComputerName alone the term isn't
recognized. Any ideas?

[Mark]

It certainly does. One of those Lenovo models that has the serial number in
the baseboard not the bios.

I'm not seeing where

1) parameter $NewComputerName is used anywhere inside function
Rename-ComputerName
2) a call to function Rename-ComputerName with a specific value for parameter
$NewComputerName is made before the Restart-Computer command is executed
