Re: Battery alarm -> was General Questions:

I'm not trying to hijack or anything, but since I posted "part" of whats
being pinged, I thought I might try and jump in on the good offers!

I have two _BPT, one per battery. This is the Method:

Method (_BTP, 1, NotSerialized) {
  SX10 ()
  SX30 (0x03)
  SX30 (0x01)
  SX32 (Arg0)
  SX11 ()
  SX12 ()
  Sleep (0xFA)
}

I have the spec PDF, I just haven't had time to really read through it.
Can anyone tell offhand what is wrong w/ mine that would cause it to not
generate noise when the battery is low? :)

I'm sure I'll get around to eventually, though. I plan on printing the
spec PDF this weekend, 4 pages per page, double sided. :)
