Latitude 7280 - Wake-on-LAN bug?
I’ve discovered a problem with the Latitude 7280 (and possibly the 7380 / 7480) that I'm wondering if anyone else can reproduce.
When the 7280 is Shutdown properly from within Windows 10, the NIC does not remain active and WOL with magic packet or Intel vPro commands will not function. However, if the laptop is switched off at the Dell logo before the OS loads, then the NIC remains active and WOL functions normally.
I have also noticed if I remove the power adapter, then reconnect it, the NIC will become active.
I have tested this with 6 different 7280 laptops.
Steps to reproduce:
Latitude 7280
BIOS version 1-6-4, set to factory defaults
Wake on LAN enabled in BIOS
Power adapter connected
Boot into Windows 10 1703 and then perform a normal shutdown. NIC should no longer be active.
Boot computer to the Dell logo then switch off. NIC should be active and WOL should work.
Could this be an issue where the laptop detects no power adapter connected after shutdown via Windows?

Hi Robert,
Thanks for the suggestion, but unfortunately those articles do not offer a resolution to this problem.

Perhaps calling Dell Tech Support (if you are an individual) or your Technical Account Manager (if you are a company) for troubleshooting would be in order.
