Hello everybody,

I own a ACER Travelmate 4001Lmi laptop and I don't manage to get battery
information with ACPI. It has an intel centrino 1,5Ghz processor and an
Intel 855GM chipset. I have compiled all necessary modules but in fact I
can only get information about the fan, the processor and thermal zone.
I can no more get the status of the adapter. I have tried different
kernel boot parameters (pci=noacpi, acpi=on, acpi=ht), but it's always
the same. With the latter, there is even no /proc/acpi directory. Here
belows is the kernel configuration concerning ACPI I have choosen:

CONFIG_ACPI=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
# CONFIG_ACPI_SLEEP is not set
CONFIG_ACPI_AC=m
CONFIG_ACPI_BATTERY=m
CONFIG_ACPI_BUTTON=m
CONFIG_ACPI_FAN=m
CONFIG_ACPI_PROCESSOR=m
CONFIG_ACPI_THERMAL=m
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_TOSHIBA is not set
# CONFIG_ACPI_CUSTOM_DSDT is not set
CONFIG_ACPI_BLACKLIST_YEAR=0
CONFIG_ACPI_DEBUG=y
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y
CONFIG_X86_ACPI_CPUFREQ=m
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set
# CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI is not set
CONFIG_HOTPLUG_PCI_ACPI=m
# CONFIG_HOTPLUG_PCI_ACPI_IBM is not set
CONFIG_SERIAL_8250_ACPI=y

In fact, in side the /proc/ac_adapter and /proc/acpi/battery, there is
nothing. So I guess there is something wrong with ac and battery
modules. Nevertheless, I am able to load these modules.

Thanks for your advices.
