Making Suspend Work On Lenovo Z510
Suspend never worked with Linux on my Lenovo Z510. Recently I came across this issue while looking for a fix (I use NVIDIA Prime, not Bumbleebee). Suspend now works on my laptop by doing:
sudo vim /etc/default/grub
Replace GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=\"!Windows 2013\" acpi_osi=Linux"
sudo update-grub
Reboot.
