Precision 3460 WOL does not work but Precision 3450 does in the S5 Power State

We are going to be upgrading the remainder of our workstations from Precision 3450s (Small Form) to Precision 3460s (Small Form).  We are having issues getting Wake-On-Lan to work on our 3460s, however the 3450s have no issue.  We have checked the settings and configurations in both BIOS and within Windows and they are identical, however to no avail the 3460s will not WOL in the S5 power state but our 3450s will.  We do have 2.5 GBE PCIE NICs in these machines but that does not make a difference as the 3450s still WOL when plugged into the NIC.  We have tried plugging directly into the motherboard ethernet port as well and still are unable to get WOL to work.  WOL does work for the Precision 3460s in hibernate (S4) but not S5 state.
