Question: Suspend VS hibernate in Linux, what is the difference?

Answer:
Suspend stops operation of all applications and system state is saved in RAM, the machine go into a low-power mode, in this state, the system still requires power . Various triggers can resume the machine, among them pressing a key or quickly pressing and releasing the power button.

Command to suspend Computer/Laptop

sudo pm-suspend

Hibernate Moves the contents of memory into swap, tells the bootloader to boot directly into the appropriate kernel, and shuts the machine down, in this state, the system does not require power. You turn on the machine by powering up, which causes the kernel to reload the contents of memory from swap.

Command to Hibernate computer/ Laptop

sudo pm-hibernate

that`s all.
