Lenovo devices report incorrect serial numbers, suggest using wmic to retrieve #3053

kevinh-csalabs commented 2 years ago

We've noticed that Lenovo devices (and possibly others) report incorrect serial number information.

I haven't looked into how this is retrieved, but the values returned via "wmic bios get serialnumber" is correct. Can that be used for querying with the current method as a fallback since the wmic data seems to be more reliable?

It currently already uses WMIC to retrieve the value. It gets it from WMIC BASEBOARD GET. It uses that, because when I triple-boot my mac, with MacOS, Windows, and linux, this value returned from this field matches the field returned from DMI in linux and IOPlatformSerialNumber in MacOS. I can do some more testing to see which values the one you specified matches with in macOS and Linux.

Ok, so I can confirm some models are returning motherboard information or other data instead of serialnumber, even though it is under a serial number column. Here is an example from an HP Pavilion - 15-cs0058od: image

I'm seeing this with Lenovo Think Pad T460s as well: image

(Serial number should start with "PC")

Unofficially Microsoft suggests using the wmic bios for this, though I have seen it come back blank before. https://support.microsoft.com/en-us/topic/how-to-find-computer-serial-number-7ceeffe0-1028-840e-dce9-d41634d54cff

Known issue from Lenovo (suggests patching bios, but not always feasible remotely: https://support.lenovo.com/us/en/solutions/ht503734-incorrect-serial-number-reported-when-running-wmic-command-lenovo-v510-14ikb15ikb

Ok, I have a few Lenovo Laptops, so I can check this out, and see if there's a way to determine at run time which field to use.

Thanks Bryan! We have a few Lenovos that are reporting correctly and most HP are correct, but some are wrong, so it seems to be a mixed bag.
