I have been told, that I might get help here. I have a Sony VAIO C1Vx.
(In my case x=E.) My problem is the power management, i.e. standby and
suspend. I was not able to get it working (properly). Is here someone
who got it working or knows, that it will not work?

My tries so far:

2.4.2 with APM:

- Fn+Fxx does nothing.
- standby makes the display black, but switches not the backlights off.
  The only way to go back to normal is by switching to a text console
  and then back to X.
- suspend is done properly, but to only way to get back to normal is
  by switching the computer off and then boot again.

2.2.16 with APM:

- Same as above.

2.4.2 with ACPI:

- I have compiled 2.4.2 with ACPI and without APM. acpid is started.
- Fn-Fxx does hang the display and probably computer until a few seconds
  after pressing a key or mouse button.
- Don't know no other way of going into suspend or standby with ACPI.

2.4.2-ac3 with ACPI:

- Same as above, but Fn-Fxx does nothing.

So do I wasting here my time or is it possible to get standby/suspend
working with the C1Vx? Has somebody got it working with APM or ACPI?
Some pointers or even a detailed description?

Thanks all
