Moving to inventory.
Do you model any of your data with Data Analytics?
Can you run an output inventory scan on one of the devices and attach that?
This document will help with that if you have never done one.
If you are not conformable attaching a scan please open a support ticket.
i know its a little bit late, but we found this issue some days ago in our infrastucture.
we did a bios update from dell and after that the model and bios was repaired and show the normal data.
by the way it was no landesk issue. also msinfo32 or a wmi script read the wrong data.
so far we get out we had the issue on E6430 and E6530 in the BIOS version A12. with A16 or A17 it will work.
We had the same problem I think.
For some PCs the service tag was being populated in the model field.
Just now, after a bit of diagnosing, I discovered that this was only occurring to PCs who have not reported inventory before 2 June 2016 04:22:00.
It did not affect any PCs after that date/time.
I know those will drop out before we run the same query next month, but I'm still wondering if the data analytics issue you briefly mentioned would have caused the problem.
Thx in advance
If you didn't configure any Data Analytics rules, it is very unlikely that those could cause the problem. More likely there are some mistakes in the BIOS as the other user reported.
