ROG STRIX Z790-F GAMING WIFI II - Ethernet and USB working after PC OFF

Level 7


Few days ago I bought this Mobo with i7 14700k and 2x samsung 990 pro. After assembling computer components and installed fresh Win11 all works fine. But... But after shutdown PC, USB and ethernet ports still working - when i press any key on the keybord, the LEDs turn on (PC not start) and the LAN port LED on the router does not turn off, it stays on all the time. It's like the Mobo is soft turned off instead hard off. I didn't find anything in the BIOS. This setting makes me concerned about the security of my computer (when PC is OFF), While the PC is turned off, I turn on the laptop and check the network monitoring program on it, which shows the PC as a working device - strange, this is the first time this has happened out of all the mobo's i'va had. Is there any setting in BIOS that will turn off these ports after shutdown the PC? This worried me becouse i have never had such of situation on any motherboard before (i7 1st gen, i7 3770k, i7 6700k -on Asus mobo, i7 8700k on MSI mobo, all on Win Vista, 7, 8, or 10), i mean on those mobo's after turn off PC the USB and ethernet ports dont work.

I installed a fresh Winn 11 for the first time and could it be a problem, I mean maybe Win11 changed someting?

My bios version is 0404 and settings: ErP Ready - disabled, Power on by pci-e - disabled. I changed ErP Ready on S5 but nothing happened.

Can you help me with this becouse i dont want the USB and ethernet ports to work all the time after i turn off the PC.

Thank you very much for all your help.

Hello, @Zawisha 

Due to the ongoing local holidays in our area, my response time may experience delays.
I apologize for any inconvenience the delayed replies may have caused.

Based on your description, considering your current BIOS version is relatively outdated, please contemplate updating to the latest version 0904 released on February 16, 2024, and recheck the situation.
Additionally, apart from adjusting the [Erp Ready] setting in the BIOS, please navigate to [Control Panel] > [Hardware and Sound] > [Power Options] > [Choose what the power buttons do] > [Change settings that are currently unavailable] in Windows. Uncheck [Turn on fast startup(recommended)] in the shutdown setting menu, and click [Save Changes].

Thank you.
