Is there any way to STD in Debian?

Hello everyone,

Recently, I need to cut off power supply with all my running tasks saved.

But it seems that the hibernate mode provided in Debian only allows me to 

Suspend to Ram(STR, or S3 mode in ACPI).

Is there any way to Suspend to Disk (STD, or S4 Mode in ACPI) in Debian?

Thank you for your replies in advance.

Best Regards,

Richard
