[ltp] Power Saving Modes (was Problem with Acpi)

[Jay Strauss]

Hi,

Being new to Linux on my thinkpad, I read the above thread, then read 
the web for a while.  I got the impression that you can suspend and/or 
hibernate.  One where stuff stays in RAM (but uses less power than 
normal??) and one where your active RAM get stored down to disk before 
you power off.

Are both of these types available on Linux?
What are the proper names for the different type of power saving modes?

Thanks
Jay
