My 2013 thinkpad on Ubuntu 20 with newest drivers doesn't wake up 1 in 5 tries.

It's frustrating, but at least now that I don't have to leave my house anymore, it doesn't matter too much!

I have this issue with my T470. I'd love to use some Linux distribution, but not waking up brought me back to Windows. A temporary solution was just keeping it on, which used up about 13% of the battery per night, but that's not a long term solution.

my T440, T470 and T495s all do the same thing. Nightmare. I use a mac mini most of the time now though.

I use a Lenovo X1 Gen 3 with Fedora 33, and have always had issues with lid close sleep/wake/hibernate. I needed to use this UPower workaround (https://www.ctrl.blog/entry/linux-laptop-low-battery-suspend...) to get it to work halfway decently, and it is still problematic.

My Thinkpad is the only computer I've ever had hibernate issues with.

At some point three or four years ago there was an article I saw where someone realized the way Linux handled memory layout during hibernate was way over complicated and they redid it much more simply. Ever since then I haven't had any issues with hibernate, either on my Thinkpad or my multiple Dell machines.

I did have a fun regression recently where my ~10 year old desktop machine started randomly hanging and it seems to be a regression of some sort in the nouveau drivers since reverting to a previous kernel version fixed the issue.

The first wakeup issue I had was on a T495... but a software upgrade fixed it thankfully.

Now another software upgrade broke my desktop's waking up which has been working fine for 4 years...
