Today I left my laptop idle by closing the lid for some time and it seems it went into deep sleep. I opened the lid and clicked mouse couple of time and even pressed the on-off button but it won't wake up. I had to do a hard reboot.
Here are my system specs.

And here is the journalctl log just before the boot and after boot.
