[ACPI-sppt] ACPI Battery Problems

[ACPI-sppt] ACPI Battery Problems

[Ian Chilton]

Hello,

I have a new Dell Inspiron 5100 notebook and I am using 2.4.21 with the
ACPI patch from http://acpi.sourceforge.net.

I can't get it to show the battery status - all I get is this:

[root@delta:~]# acpi -V
     Thermal 1: ok, 40.0 degrees C
  AC Adapter 1: off-line

Also, I have had a few times running on power or battey where I have
been working away and the machine has either powered off or hard reset.


I have the folowing options in my kernel:

[root@delta:~]# grep ACPI /usr/src/linux/.config
# CONFIG_HOTPLUG_PCI_ACPI is not set
# ACPI Support                  
CONFIG_ACPI=y                   
# CONFIG_ACPI_HT_ONLY is not set
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_BUS=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SYSTEM=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y

CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_TOSHIBA is not set
# CONFIG_ACPI_DEBUG is not set


I get the following at boot:

[root@delta:~]# dmesg |grep -i acpi

yeah, your DSDT is just as broken as every other Dell DSDT I've heard of.  I
never have managed to properly fix mine (Inspiron 2500).  And as long as your
battery method is broken it's always going to shut down precipitously when the
battery runs out...

FWIW, 2.5.73+ booted w/ acpi_os_name='Microsoft Windows NT' does show
accurate battery and ac info on an i8100 w/ a14 bios.  (they are up
to a15 for the 8100.)

My next test is .74+ with acpi_os_name='Windows 2001'.

(The two acpi_os_names come from the dsdt; the latter is what the
dsts expects for xp.)

I'm not sure whether the patches that went in to 2.5 since 2.5.70
fixed it, or whether the dsdt just works better if it gets to store
0x10 or 0x40 into MIS3....  But I suspect the patch is more important.

(Incidently, not specifying an acpi_os_name for that dsdt is the
same as specifying win98 aka acpi_os_name='Microsoft Windows'.
The 4th choice is win me.)

Thanks.  I recall Bruno mentioning this for other machines, and have 
always meant to try it...

Most of ASL I saw will more likely use the _OSI() method for Windows XP.
I'm also wondering if that will be OK to implement it (but with
a configure option or perhaps better a boot option).

Yes, I did miss that.  Dell does this:

Method (OSID, 0, NotSerialized)
    {
        If (LEqual (MIS3, 0x00))
        {
            Store (0x04, MIS3)
            If (CondRefOf (\_OSI, Local0))
            {
                If (\_OSI (WXP))
                {
                    Store (0x40, MIS3)
                }
            }
            Else
            {
                If (STRE (\_OS, W98S))
                {
                    Store (0x08, MIS3)
                }

                If (STRE (\_OS, NT5S))
                {
                    Store (0x10, MIS3)
                }

                If (STRE (\_OS, WINM))
                {
                    Store (0x20, MIS3)
                }
            }
        }

        Return (MIS3)
    }

So I was even wrong about the default.  0x4 is used for anything not
98, nt5, me or xp.

In any case, booting w/ acpi_os_name='Windows 2001' still allows the
battery etc stuff to work, so it is obviously indeed the recent
patches that fixed handling less-than-ideal dsdts.
