Lenovo p16gen1. Dealing with warranty for 3 months, got replaced with p16gen2 that has same issues, but I'd like to use a computer, not having it at service all the time. Modern standby is just what it really sounds. Modern - completely broken.
I have the hope that Lenovo acquiring Phoenix will fix some of the awfulness.
There is a guide on Reddit, "How to enter advanced BIOS options on Gen 1 T15(g/p), P15(v), P17" which also applies to each generation of P16. It's possible a setting in there will finally cure your laptop's insomnia?
Back in the day the old thinkpads would just immediately shut down CPU and fan together and that was it.
Modern standby is completely crap.
