Hello,
Even if SEPM retreive a lot of hardware information, like processor model, processor number, Processor type clock stepping, ram intalled, mac addresses, Bios Version, the computer serial number is not a part of these information. You can get these information by make an export of the result og log query in the control Menu, then choose your computer or group, do not select any filter, then on the result, click on export and open the .csv fil witch Excel.
A free application can be used to get these information and have a full management system for team support : OCS inventory from SourceForge.
