Can’t start session after battery drain off

It seems the file system is damaged and therefore it can’t read the superblock. So the normal repair at boot did not work.

You will need boot a manjaro boot disk and repair it:

list all backup superblocks:

sudo dumpe2fs /dev/sda5 | grep -i superblock

and then

sudo fsck -b <superblock> /dev/sda5

like this:

sudo fsck -b 32768 -y /dev/sda5

You will need to test every superblock until it works.

If it worked, it is also useful to detect badblocks and tell ext4 to skip them:

sudo fsck -vcck /dev/sda5

Good luck
