Public bug reported: I suspend the laptop either by closing the lid or by GUI clicking on Suspend option (Pohotovostný režim in Slovak). I resume from suspend either by opening the lid or by pressing the power button. In either case the PC resumes for about a second then power goes off (I hear the hard disk going off) and the system restarts. Then it is OK. I think that the problem started after updating the kernel to version Linux 4.15.0-115-generic (i686). Now I use the version 4.15.0-117-generic (i686). I have never faced this problem before and I run Lubuntu on this PC for more than year. I cannot provide information required by Ubuntu Wiki in section DebuggingKernelSuspend as I have not installed the nondaily mainline kernel. Issuing the command "sudo cat /sys/kernel/debug/suspend_stats" I obtained the following output:
