Having Ubuntu 22.10 and 22.04 booted from a live USB will freeze before or little after the graphical interface is displayed. Hence, I tried an older version, namely 18.04.6.

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.
