Hi once again,
I've looked around a little in the ACPI kernel code, increased the
debug_level to maximum, but everything seems ok... there is no notable
difference in the operation of getting the thermal zone status (which
works) and getting the battery status (which doesn't). The only strange
thing I have is this (during bootup):
[ACPI Debug] String: [0x2E] "-------------------BAT1_STA, slot is connected"
[ACPI Debug] String: [0x29] "-------------------------------- BAT1_BIF"
[ACPI Debug] String: [0x32] "--------------------------------Set P4.0 : OS-BAT1"
[ACPI Debug] String: [0x35] "--------------------------------BAT1 is still present"
[ACPI Debug] String: [0x2B] "--------------------------------ACCESS UPBI"
[ACPI Debug] String: [0x2B] "--------------------------------ACCESS UPBS"
[ACPI Debug] String: [0x28] "------local0.0 = BAT1 PBIF modified-----"
[ACPI Debug] Integer: 0x00000003
[ACPI Debug] String: [0x28] "------local0.1 = BAT1 PBST modified-----"
ACPI: Battery Slot [BAT1] (battery present)
[ACPI Debug] String: [0x2A] "-------------------BAT2_STA, slot is empty"
ACPI: Battery Slot [BAT2] (battery absent)
I'm a little bit curious about the "modified" message - even more as
I wasn't able to locate that string in the C ACPI code, so I guess it
comes from the depths lying below C...
Anyway, when the bootup process is completed, it happily queries (but
to no effect)...
Jan 10 09:59:05 localhost kernel: [ACPI Debug] String: [0x2A] "-------------------------------- BAT1 _BST"
Jan 10 09:59:05 localhost kernel: [ACPI Debug] String: [0x40] "-------------------------------------------------- _TZ.THRM._TMP"
Jan 10 09:59:10 localhost kernel: [ACPI Debug] String: [0x2A] "-------------------------------- BAT1 _BST"
Jan 10 09:59:10 localhost kernel: [ACPI Debug] String: [0x40] "-------------------------------------------------- _TZ.THRM._TMP"
Jan 10 09:59:15 localhost kernel: [ACPI Debug] String: [0x2A] "-------------------------------- BAT1 _BST"
Jan 10 09:59:15 localhost kernel: [ACPI Debug] String: [0x40] "-------------------------------------------------- _TZ.THRM._TMP"
Jan 10 09:59:20 localhost kernel: [ACPI Debug] String: [0x2A] "-------------------------------- BAT1 _BST"
Jan 10 09:59:20 localhost kernel: [ACPI Debug] String: [0x40] "-------------------------------------------------- _TZ.THRM._TMP"
Oh, and a last side note: The Evil OS[tm] can read the battery state
just fine - at least old 98SE can, I've got nothing more recent to
test that.
Thanks for reading all this... anyone got a clue?
Jan
PS: Oh, and to H.S.: Logging in and out of X has no effect here -
but I don't use gnome, just plain xdm + blackbox.
