Hello,
There are multiple models of HP Pavilion dv6 …
A small arch wiki exists for dv6018 here:
https://wiki.archlinux.org/index.php/HP_Pavilion_dv6018
That doesn’t add the resume to the /etc/mkinitcpio.conf on the HOOKS line, nor does add the resume=UUID to /etc/default/grub on the GRUB_CMDLINE_LINUX_DEFAULT line …
Do you have all of those?
