SDB:Suspend to RAM
Suspend to RAM is working on many systems. It saves the system-state to RAM and puts system components in energy-saving states. The RAM will still be powered on. After waking up the system resumes operation.
There are machines that will not resume when using a framebuffer console. Some Dell and HP models for example fall into this category.
You can disable the framebuffer in your bootloader configuration by passing "vga=0" to the kernel. The configuration for grub is often found in /etc/default/grub.
If your machine only works without framebuffer, please tell us about this in your report.
