If anyone at Lenovo reads this thread, test and fix your EC firmware---both earlier and to a higher standard. The support forums constantly reveal EC-realm issues: suspend broken, lid switch screwy behavior, odd interrupts causing battery drain, holding power 10 seconds does not work during some hangs, keyboard stops working (even in the BIOS tests in some cases), long startup, keyboard beep setting is ignored, changing settings via /proc/whatever does not always persist, and the list goes on. Every BIOS update has half a dozen EC-related "fixes", so it's clear that problem discovery and reporting is left to the customer. So many Linux desktops run 6.6, 6.7, 6.8 totally fine, which to me suggests a problem involving addition of a battery, low-power states, and the controller tying all that together. I will never buy another modern ThinkPad. It has cost too much of my productivity figuring out problems that should crop up in internal testing and never, ever reach the customer. I was able to find (and document) ten showstopper bugs in the first week of owning the damn thing!
