I had Windows 10 Pro on this Dell Latitude 7390 which worked fine. I then booted 18.04.6 from live USB and had Ubuntu running good and well, have done an OS backup of Windows 10 and then went ahead and installed Ubuntu 18.04.6 on it, wiping everything off. Ubuntu 18.04.6 runs well on this laptop now UNTIL IT GOES INTO SUSPEND / HIBERNATE. After which won't wake up as expected. Instead, I have to do a hard reset and boot the system again. My hardware knowledge isn't that great, however, I believe this it not a hardware fault? Win 10 would have issues too? And Ubuntu would have issues too, prior to going into suspend / hibernate? Moreover, the "processor fault" could result in some command it gets when trying to the system into suspend? Moreover, why would Ubuntu 18.04.6 boot from a live USB stick and 22.04 or 22.10 wouldn't or if it does, will freeze shortly after showing the graphical desktop? I can restore Windows 10 and keep it as such, I just like Linux, esp. Ubuntu.

The system is non-recoverable after it goes into sleep. Or after the screen is locked by the user and after it fades to complete black. System becomes unresponsive, no mouse or keypress will get the system back on to work. If the systemctl suspend is issued, the system will not wake up again. Hard reset is needed. If Ubuntu 18.04.6 is booted from live USB, the same is happening. Sometimes, when the system is rendered unresponsive as a result of any of the above, the power led is sending the message of "processor failure" (2 x amber blinks followed by 1 x white blink). Any help is greatly appreciated! I will keep the system as is, without applying any updates for now.
