Hi,
Was looking how to get battery discharge rate on this laptop.
This is part of DSDT:
Name (PBST, Package (0x04)
{
0x00,
0xFFFFFFFF,
0xFFFFFFFF,
0x2710
})
...
Method (_BST, 0, NotSerialized)
{
If (ECON)
{
If (\_SB.PCI0.LPCB.EC0.MBTS)
{
UPBS ()
}
Else
{
IVBS ()
}
}
Else
{
IVBS ()
}
Return (PBST)
}
...
Method (UPBS, 0, NotSerialized)
{
Store (\_SB.PCI0.LPCB.EC0.MBRM, Local5)
If (LNot (And (Local5, 0x8000)))
{
ShiftRight (Local5, 0x05, Local5)
ShiftLeft (Local5, 0x05, Local5)
If (LNotEqual (Local5, DerefOf (Index (PBST, 0x02))))
{
Store (Local5, Index (PBST, 0x02))
}
}
Store (\_SB.PCI0.LPCB.EC0.MBCV, Index (PBST, 0x03))
Store (\_SB.PCI0.LPCB.EC0.MBST, Index (PBST, 0x00))
Store (\_SB.PCI0.LPCB.EC0.BA1C, BCAP)
}
and method IVBS just stores default values into PBST.
So, I'm not familiar with iasl and rest, but if I understand right, UPBS
method is used in case when battery connected and known to system.
In UPBS method I don't see any code that updates PBST at 0x01
(discharge_rate). HP support says that sensor is present in system.
Any ideas where this sensor located and how can I get discharge rate
visible in ACPI (kernel 2.6.18.2)?

Thank You..

I guess your DSDT does not support 'present rate'.
Look in /proc/acpi/BAT*/state file. The 'present rate' field is the PBST
at 0x01. I expect the 'unknown' (0xFFFFFFFF) value of 'present rate'. Is
it?

It's likely under the embedded controller. If you give me the whole
OperationRegion() and the Field() for that one it might be possible
I could have a hint to get it.
It should be something like that:
Device (EC0)
{
...
...
OperationRegion(XXXX, EmbeddedControl, 0x00, 0xFF)
Field(XXXX, ByteAcc, ..., ...)
{
...
...
}
...
}
I'll need all the Field with the same name (here XXXX).
Or alternatively send to me the whole ASL.
Cheers,
