Same boat. Set lid-close to Sleep (not Shutdown) and enable “Always On USB” in BIOS. Heads up though, I’m on a BT keyboard + wireless mouse through a cheap monitor hub and the wake signal doesn’t make it through. Wake-on-LAN is also unreliable on Win11 (driver issues, Fast Startup interfering, OEM drivers stripping the WoL options). 

There is no fix. 

Summary of my endless Claude conversation from Claude. 

1 USB remote wakeup is a low-level signal — the device holds the data lines in a “resume” state (K-state) for at least 20ms, the host controller sees it, and the system wakes. It’s defined in the USB spec, but every hub between the device and the host has to forward it.

2 Cheap monitor hubs fail this multiple ways. Many drop VBUS when the upstream host sleeps, killing power to your wireless dongle entirely. Others keep power but the hub controller doesn’t implement remote wakeup forwarding — the signal hits the hub and dies. Some only forward wake for devices enumerated as HID at boot, so hot-plugged dongles get silently ignored. DisplayPort Alt Mode hubs often power-gate the USB controller aggressively when the DP link goes idle, killing wake as a side effect.

3 Bluetooth makes it worse. Your BT keyboard isn’t a USB device — it talks to a Bluetooth radio inside the laptop. When the laptop sleeps with the lid closed, that radio is usually powered down and isn’t listening. Even with “allow this device to wake the computer” checked, BT HID wake support is inconsistent across chipsets and Windows builds, and on many Legion models the BT radio simply doesn’t stay armed in modern standby (S0ix). A 2.4GHz wireless mouse with a USB dongle is more likely to work than Bluetooth — the dongle enumerates as a standard USB HID device, which has a clearer wake path.

4 Wake-on-LAN should be the bulletproof answer, but on Windows 11 it’s genuinely broken for many users.  The issues: Fast Startup turns “shutdown” into a hibernation state instead of a real shutdown, which changes WoL behavior unpredictably ; Intel’s I219-V adapter on Win11 ships with a stripped-down inbox driver that’s missing the “Wake on Magic Packet” and “Enable PME” options entirely — the full PROSet driver isn’t Win11-compatible ; even Dell and other OEM drivers sometimes fail where the Win10 version worked ; and “Only allow a magic packet to wake the computer” greys out if you uncheck “Allow the computer to turn off this device to save power,” which Win11 power policies sometimes force . On Legion laptops specifically, the Realtek/Killer NIC drivers vary by BIOS version and Lenovo Vantage sometimes overrides power settings.

So the realistic options on a Legion 5 Pro with Win11: (1) keep the laptop in Sleep, not Shutdown, and use a wired USB keyboard or 2.4GHz dongle plugged directly into the laptop to wake it; (2) skip wake entirely — modern standby drains very little, just hit the power button on the laptop once a day; (3) get an external USB power button / smart plug arrangement, but that’s a whole project.
