There was an issue with hibernate memory mapping that broke hibernate on my work Thinkpad for the first year or two that I had it.
Then at some point they fixed the issue, which if I remember correctly came down to "stop trying to be fancy and just do the straight-forward thing, which is correct". And since then I've had no issues.
I'm unclear why I had an issue with the Thinkpad but never had issues with any of the 5 or so Dell Inspirons I've had over the years.
As a counter point, I've had repeated issues with my several different laptops in the last few years with them not going to sleep (2015~2018?). I have a new laptop now that I primarily run windows on now...
