Enable WoL on MSI B760M Mortar | Generated by AI
Question: In this computer with the MSI MAG B760M Mortar WiFi motherboard, how to boot into BIOS/UEFI and enable “Wake-on-LAN” or “PCIe/PCI Wake” under power management settings?
Answer:
For your PC with the MSI MAG B760M Mortar WiFi motherboard (MSI B760 series), follow these exact steps to enter the BIOS and enable Wake-on-LAN (WoL). The process is standard for recent MSI gaming motherboards like yours.
Step 1: Enter the BIOS/UEFI
- Completely power off the computer (full shutdown, not sleep or hibernate).
- Press the power button to start the system.
- Immediately and repeatedly tap the Delete (Del) key right after pressing the power button (start tapping even before the screen lights up).
- Keep tapping Del quickly until the BIOS setup utility appears (MSI logo or black screen with options).
- This is the correct key for your motherboard (confirmed across MSI B760 models and official guides).
- If Del doesn’t work after several attempts (rare), also try F2 repeatedly during the same early boot phase.
- Tips:
- Use a wired USB keyboard connected to a rear USB port (avoid wireless or front-panel ports for initial entry).
- If Windows Fast Startup is enabled, it can make the boot too fast to catch the key — use the Windows alternative method below first if needed.
Alternative method from inside Windows (if you can boot to the OS):
- Open Settings → System → Recovery.
- Under Advanced startup, click Restart now.
- After reboot: Troubleshoot → Advanced options → UEFI Firmware Settings → Restart.
- This boots directly into BIOS.
Step 2: Enable Wake-on-LAN in BIOS
Once inside the BIOS (it may start in EZ Mode — press F7 to switch to Advanced Mode if needed):
- Use the mouse or arrow keys to select SETTINGS (usually on the top/left menu).
- Go to Advanced → Power Management Setup (or sometimes directly under Advanced).
- Find ErP Ready (or EuP 2013 / ERP Ready) and set it to Disabled.
- This is important — ErP enabled cuts power to PCIe devices (including the network controller) during shutdown, which prevents WoL from working.
- Go back (or navigate) to SETTINGS → Advanced → Wake Up Event Setup (sometimes called Wake Event Setup or similar).
- Locate Resume By PCI-E Device, Resume By PCI-E/Networking Device, Resume By PCIe Device, or Power On By PCI-E Device.
- Set it to Enabled.
- This is the main Wake-on-LAN / PCIe wake setting (your board uses a PCIe-connected 2.5Gbps Realtek LAN controller, so this covers it).
- (Optional but recommended) Look for related options like Wake Up Event By and set to BIOS (instead of OS) for more reliable behavior in some cases.
- Press F10 to Save Changes and Exit, then confirm Yes.
- The system will restart into Windows.
Additional Important Steps (After BIOS)
For WoL to fully work after shutdown:
- In Windows: Open Device Manager → Network adapters → right-click your Ethernet controller (likely Realtek Gaming 2.5GbE Family Controller) → Properties → Power Management tab:
- Check Allow this device to wake the computer.
- Check Only allow a magic packet to wake the computer (optional, but more secure).
- Also disable Fast Startup in Windows (Control Panel → Power Options → Choose what the power buttons do → Change settings that are currently unavailable → uncheck Turn on fast startup).
- Ensure your Ethernet cable is plugged in (WoL typically requires wired LAN, not Wi-Fi on this board).
This configuration matches official MSI WoL guides and user reports for B760-series Mortar boards. Test by shutting down the PC completely and sending a magic packet from another device (using tools like WakeMeOnLan or apps).
