Description Matthew Mosesohn 2011-05-27 14:11:39 UTC
Description of problem:
Red Hat IT uses the asset tags to track our laptops for auditing purposes.  It's important to be able to read these values from the system, rather than inspecting externally.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install RHEL 6.1 on a Lenovo ThinkPad T410 with a value set in the Asset Tag field in the BIOS
2. run dmidecode -s chassis-asset-tag
Actual results:
# dmidecode -s chassis-asset-tag
No Asset Information

Expected results:
# dmidecode -s chassis-asset-tag

Additional info:
This is not a problem on Lenovo T510, X201, T520, or T420 model laptops.  We are not concerned about older models than that, and we don't have access to the new X220 model yet.

Comment 2 Matthew Mosesohn 2011-05-27 15:35:23 UTC
Correction:  The asset tag displays properly on the other Lenovo ThinkPad models: T510, X201, T520, T420

Matthew, could you try a newer dmidecode:

and attach binary dump to the bugzilla, dmidecode's --dump-bin option.

Comment 5 Anton Arapov 2011-06-28 06:31:08 UTC
  there are no relevant info in the dump, so the dmidecode has no source to expose the asset tag. This can be a BIOS issue as well. Try to update the BIOS to the latest one and reproduce. I will look for T410 on my side as well.... 


Comment 6 Matthew Mosesohn 2011-06-28 13:21:03 UTC

I've got a system with an updated bios.  I'll get a report of it in a few hours using the new dmidecode.

Comment 7 Matthew Mosesohn 2011-07-20 12:10:24 UTC
This bug is invalid.  The systems don't have a physically coded asset tag.  There's no problems with dmidecode.  The problem lies with the vendor

Cool, thanks for taking a look.
