Help: Logitech Keyboard Won't wake Win10 from sleep and doesn't work after waking.

Because the receiver is unrecognized after wake on every port but works after reboot, this looks like a USB resume-state failure rather than a pairing problem.

After failure, check Event Viewer, System for Kernel-PnP or USB errors at the wake time and record any status code. In Device Manager, uninstall only the Logitech receiver USB composite device, then perform a full shutdown and power-on. Install the PC manufacturer’s BIOS, chipset, and USB-controller drivers and the receiver manufacturer’s current software. Check powercfg /lastwake and powercfg /devicequery wake_armed to separate “cannot wake” from “fails after wake.”

Test the receiver on another computer after sleep, and test another USB keyboard on this PC. If only this receiver fails, replace or re-pair it; if several USB devices fail after sleep, escalate the controller or firmware. Windows 10 support has ended, so include migration to a supported release in the long-term plan.
