It looks like there is an I2C operation region that the AML code uses to handle the battery specific things: Scope (_SB.I2C1) { Name (UMPC, ResourceTemplate () { I2cSerialBus (0x0048, ControllerInitiated, 0x000186A0, AddressingMode7Bit, "\\_SB.I2C1", 0x00, ResourceConsumer, , ) }) Name (AVBL, Zero) Method (_REG, 2, NotSerialized) // _REG: Region Availability { If (LEqual (Arg0, 0x09)) { Store (Arg1, AVBL) } } OperationRegion (DVUM, GenericSerialBus, Zero, 0x0100) ...

In the original email from Adam to linux-acpi@ both were attached but somehow I can't find that email from archives.

In the meantime, I found https://github.com/rjwysocki/linux-pm/commit/b2a51a6d0f96308251cfa41b793c43d0316e3b16 , which looks like it may be relevant to my hardware. I'm building a kernel with that patch added, and I'll see if it makes any difference. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net ^ permalink raw reply [flat|nested] 5+ messages in thread
