Hi!

Actually, I don't think that's good idea, at least on PC.
The way to wake up from S3 is power button. The way to wake up from
"echo freeze > state" is going to be different, right?
If I disable S3 in the BIOS and get different result from "echo mem >
state", that will be confusing.
Similar (but less severe) problem is there with S1, as it will
probably power down USB ports, etc.
So for example if I have system with S1, learn to do "echo mem >
state" and that it still charges my phone, then ACPI updates come and
"echo mem > state" now puts it in S3 and not charging my phone -- that
would be confusing.
Pavel
