Hi,
I have never seen my Notebook shutting down correctly,
e.a. I can see the line Powering system off using ACPI
and it stays there. Well, it's not critical, because I
can still press the power button. But I think it has
generally problems with ACPI.
This is what I get when booting current (dmesg):
acpi0: IBMTP-1Pon motherboard
acpi_ec0: embedded controller: ECDT, GPE 0x1c, GLK port 0x66,0x62 on
acpi0

acpi0: AcpiGetSleepTypeData failed - AE_NOT_FOUND
This is _after_ flashing with the latest BIOS. Before flashing,
I always got about 2 screens of these Method execution failed
messages. After flashing the BIOS the functionality hasn't changed
at all, but at least these ugly errors disappeared.
I can see the battery status correctly in Gnome2, for example,
but what does not work is the sleep and the power button. The
sleep button just gives me a message on the console.
Playing with acpiconf -s will make the notebook hang.
I want to give you information about this notebook and its
ACPI capabilities, but I have no idea what's the best way
(acpidump?).
I could not find any useful hints online and I don't know if
it's IBM's fault. Can someone explain what's going on?
