T620 serial number 00000 and description "HP Thin Client"

[leo07663]

This is more of me sharing the solution I found to this problem. Found a couple of entries asking but not listing a solution.

My issue consists on thin clients not reporting the proper serial number and only showing zeroes in the console. Also the description shows a generic "HP Thin Client" as opposed to the actual model number.

This is a problem because I cannot get a report on patches currently installed in the client. I also have issues when I try to reimage one since the console cannot properly tell if the model matches the image.

Current setup I am running is console and client 4.7 SP 6.

I found that the WMI is corrupted. I ran a command on them: wmic BIOS get serialnumber and it gives me an error. I took a separate unit and put a fresh image in it. I then backed up the MWI, moved it to a broken unit and restored that backup on the broken unit. It fixes the issue and now the broken unit reports fine and allows reimaging without a problem.

Commands I ran:

on a newly imaged unit:   winmgmt /backup c:\backup

Copy that backup file to a broken unit (Ex. c:\Temp\)

On a broken unit:

winmgmt /restore c:\Temp\backup 1

Reboot.

Thin client should report serial and type of unit just fine now.

Hi Leo,

Thanks for sharing information!

I have some little bit different situatuon where in one of the windows thin-client model t620 in the column of Device serial Number nothing visbale completly blank without any number.

i already tried your command below, firstly copied backup file from the working same model client then copied and restored after restart nothing effect.

while RDP to client and trying to run following command :

WMIC BIOS GET SERIALNUMBER

Output command isn't showing SerialNumber of client.

Even tried to re-imaged the client but still same problem, device Agent version also updated but i really dont know why its not showing serial number even from the OS prospective it looks good.

Thanks in advance.
