I'm using a Lenovo Notebook that randomly freezes. When I mean random, it's REALLY random, the machine has been on for a week without freezing, freezing when no apps are opened, freezing when opening three tabs in Chrome, freezing when opening terminal, you get the idea.

I want to know which logs or where can I look to try do debug this. I've already run the Lenovo diagnostics for memory and such and no problems were found.

I had the same problem and at least for me there were 2 problems:

The first one was a problem with my video card, so I had to go to bios settings and uncheck the Switchable graphics option.

And the second one, was related to Chrome using a lot of memory and I had to disable chrome hardware acceleration, take a look a this to see if it helps.

I hope this will work for you. I've faced the same problem that Ubuntu 18.04 freezes from time to time. Ubuntu 18.04 completely froze while I was coding, then sometime later the same happened when I watched a movie it was a problem that was not related with the GPU and had random occurrence. I've found this solution after hours of searching. Just run this command and restart your computer. 

sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

After restarting, verify that the 5.0.0.x generic was installed:

uname -a

That'll work fine.
