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)?
PS: Please, reply to e-mail directly because I'm not subscribed to this

Thank You..
