Not sure if my E495 would qualify as a "proper thinkpad", although I've read about the same issues on T series laptops, I've almost never managed to make my laptop sleep in the 3 years I've owned this laptop starting from kernel version 5.4.x to the present 5.19.x. Whenever I try to 'systemctl suspend', one of the following things happens

- the laptop sleeps for a few seconds and wakes up

- the laptop sleeps for a few seconds and wakes up completely frozen and I have to perform a hard reboot

- the laptop doesn't sleep and freezes and I have to perform a hard reboot

- the laptop sleeps successfully but when I wake it up, the screen is messed up with green colors all over the place, hard reboot needed

My laptop also kept freezing randomly from 5.4.x to 5.14.x.

The T- and X-series is what people usually refer to as the "real" Thinkpads, which existed before this Lenovo nonsense. Lenovo labels widely varying hardware under the Thinkpad brand, but that's not what you want as a Linux user.

I don't know about the E-series specifically, sorry.

As I wrote before, I have observed similar issues reported by many T series owners when I was desperately scouring the Internet for a fix for months. Of course, I haven't used a T series ThinkPad so I can't say if these issues got resolved or not. I gave up long ago and now keep my laptop on 24x7 when I'm not traveling.

Conversely, I have a ThinkPad X1 running Fedora 36 (and, previously, 35), and it has never given me a problem ... well, other than because I messed with one too many things. The only thing I did was to disable the so-called "modern suspend" in BIOS and it has run like an absolute dream.

Not trying to contradict you. Just noting how even within one manufacturer's footprint (and "linux" however we define that for the purposes of this conversation) YMMV.
