> How’s ACPI and real suspend

On a current ThinkPad? Essentially perfect. Zero problems suspending and resuming, no matter what's going on, including weird cases like suspending while docked and resuming while undocked or vice versa.

It's a toss up. Works great on my 2017 X1 Extreme. Doesn't work on old 4th Gen i3/i5 E550 thinkpads I refurbish, etc.
