I work with a company that repurposes laptops for companies, and we get orders of around 20-100 laptops per order. We install brand new images on them after we refurbish the laptop itself, but we are having problems with writing an automatic naming script. I was tasked with finding a script that can do the following:

  1. Read the serial number from the bios of the laptop
  2. Compare this serial number to a spreadsheet or CSV file, and find the serial number there
  3. Then, find the desired computer name in the column next to the serial number
  4. Finally, rename the computer using the new name found in the file

It is much easier to write one big spreadsheet file with names and serial numbers, than it is to type each new name in CMD prompt and restarting each computer individually.

So far I have the following script to use the serial number as a variable, if need be:

for /f "skip=1 delims=" %%J in ('wmic bios get serialnumber') do (set serial=%%J Goto :done) :done

After we have this script, typing %serial% inputs the serial number specific to that computer.

I also know that the following script will rename the computer, using a variable as the new name:

wmic computersystem where caption='%computername%' rename %variable%

Where %variable% is the variable we will hopefully find in the spreadsheet. I just don't know how to find that new variable (new computer name) that would be found in the spreadsheet. Any help would be greatly appreciated.

  • I would also be willing to write this scripting in PowerShell, but I've never used PowerShell before. The laptops that I am running this script on will need to be clean, and not have any downloaded material before we send them out as well, so please keep that in mind. – Umbrathe Jun 06 '16 at 18:48
  • Assuming your CSV is in the form of `SerialNumber, Hostname`, then you can use [FIND](http://ss64.com/nt/find.html) to get the line in the CSV. The [split the line](http://stackoverflow.com/questions/1707058/how-to-split-a-string-in-a-windows-batch-file) using `FOR` to get your computername. – Tim Jun 06 '16 at 21:09

The following is the code that I used for the problem that I was having.

for /f "tokens=2 delims==" %%J in ('wmic bios get serialnumber /value') do set serial=%%J
Find /I "%serial%" {Location of file} > {Location of confirmation file}
For /f "tokens=1,2* delims=," %%G in ({Location of confirmation file}) do set HN=%%H
wmic computersystem where caption='%computername%' rename %HN%`

Looks complicated, but by lines of text they do the following:

1) Finds the serial number from the bios

2) Finds the line in the CSV file and outputs the whole line into a text document

3) Sets the desired name from the text document as a variable

4) Renames the computer name to this desired variable name
