[ltp] ACPI R40

[d.lj]

hy, speaking of all this, i just switched to acpi on the R40 and
surprisingly i have a couple of question ... ;)


* swsusp (echo 4 >/proc/acpi/sleep) works fine except it doesnt shutdown
completely but i have to press the powerbutton for a few seconds (the
force method) to really power off.

* echo 3 doesnt, i.e. the laptop goes into the moon-mode (status light)
very quickly but i m not able to wake it up again, also i cant shut it
off with the power button but have to unplug ac, remove the battery.

* how do you map fn+F4 resp. fn+F12 keys to echo 3, 4?

i ve tried on 2.6.0-test9 and 2.6.0-test9-mm4, both show same behaviour.

as usual any hintz are appreciated.

 |Absolutely.  That being said, though, I haven't seen the point of
 |suspend to disk, versus suspend-to-memory.  It doesn't take *that*
 |much power to keep the memory refresh circuits going, especially when
 |you have to compare it with the amount of juice to write a heck of a
 |lot of data to disk.  Suspend to disk also takes a lot longer than a
 |suspend-to-memory.
 |
 |Fortunately, while hibernation (suspend-to-disk) doesn't seem to work
 |for me with my T40, suspend-to-memory works fine, as long as I'm using
 |APM and not ACPI.  It's annoying that I can't get the exact discharge
 |rate of the batteries like I could with ACPI, but suspend-to-memory is
 |infinitely more important.
