Adding s3_bios to kernel parameters didn't work for me. The suspend just does not work anymore. Laptop wont suspend anymore.
My hardware: Asus -K55N Radeon HD7250G
You can also try: acpi_sleep=s3_mode or acpi_sleep=s3_bios,s3_mode
A little info here:https://www.kernel.org/doc/Documentation/power/video.txt
Neither of that work. Also I am booted in UEFI mode, if that helps?
