After installing Ubuntu 17.04 a week ago on my /dev/sda1 partition, all was working properly.
Closing the lid put my computer into suspend mode.
Opening it up, touching a keyboard touch turned it on, as expected.
I installed a set of packages and used it normally.
Then yesterday my chromium / computer freezed completely so I hard-rebooted it.
Ever since, right after the startup screen displaying the word "Ubuntu" upon purple background, there is a quick (1sec) white-on-black text screen message :
On Day one :
/dev/sda1: recovering journal
/dev/sda1: clean 202498/1525920 files, 1470005/6103515 blocks
On Day 2 (few reboots, no real usage nor pkg installations)
/dev/sda1: recovering journal
/dev/sda1: Clearing orphaned inode 130826 (uid=112, gid=118, node=0100644, size=2547)
/dev/sda1: Clearing orphaned inode 130837 (uid=112, gid=118, node=0100644, size=2547)
/dev/sda1: Clearing orphaned inode 130825 (uid=112, gid=118, node=0100644, size=2547)
/dev/sda1: Clearing orphaned inode 130834 (uid=112, gid=118, node=0100644, size=2547)
/dev/sda1: clean, 202523/1525920 files, 1478967/6103515 blocks
And, when I close the lid, opening it back turns the PC on (without pushing the button). I lose all running apps, my browser tabs, etc.
Test | Way to suspend | Status | Way to open | Result
#1 | close the lid | Suspended (lightbulb icon light=flashes) | Open the lid > press a touch | Reboots fully
#2 | (menu) > Suspend | Suspended (idem) | Press a touch | Reboots fully
#3 | time goes | Suspended (idem) | Press a touch | Wake up with previous apps
Any idea how I can solve this and get proper suspension via lid closing and Menu>Suspend ?

Lets first check your file system for errors.
To check the file system on your Ubuntu partition...
sudo fsck -f /reboot
