My computer will not wake from suspend. Anytime I try to wake it from suspend (whether the system was manually or automatically put into suspend), it doesn't display anything. The only signs of life from my computer are the fans are spinning and my keyboard lights turn on. I have to hit the reset switch on my computer in order to see anything.

I'm not sure what else to do, I tried switching drivers from Nvidia drivers to Nouveau drivers and I still have the same issue.

I would love if anyone can help me with this issue, and I'd be happy to provide system logs if requested (I don't know where to find them).

I also would like to continue using suspend, rather than just disabling automatic suspend.

I think I found it. Ubuntu 18.04 alternating between successful boot and failed boot tells you to:

  • open /etc/default/grub
  • on row GRUB_CMDLINE_LINUX_DEFAULT add dis_ucode_ldr
  • run update-grub
  • reboot

There seems to be a faulty microcode patch in package intel-microcode which gets loaded by grub on each boot, unless you tell grub not to load it. This is a temporary fix, until the faulty code gets removed,
