Hello there! The feedback is appreciated. (I may sound like an Ubuntu 
tech representative, which I'm not). When you say things like " when I 
tried to run "update-grub2" it just hangs ", it's weirdness land to me. 
Shouldn't definitely be happening.

Few things I hold certain in this life, one of them is between major 
releases such as this, you start from scratch. I mean, I create a new " 
GPT " disk table (can't remember is you're dual-booting here). Worth 
every second of time for long-term new installs.

Now, have you looked entering the " BIOS " hardware settings on anything 
" ACPI " related (can't remember from your previous posts if you did)? 
You would look for " ACPI " and power management settings and tweak with 
them with little reason. Or, again, just try to start from scratch with 
" LOAD DEFAULTS " and " SAVE " on " BIOS " settings.

From own experience, if you disable (for example) processor power 
management on " BIOS " (when available), helps! Let the installed 
(latest) software do its thing, instead.

I therefore would focus on " BIOS " settings now (of course, assuming 
your hardware is okay).

Thank you. Fernando.
