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. :) > Rockefeller, Harry wrote: > > > > > > > My notebook, Uniwill N351S1, is - supposedly - both APM and ACPI 2.0 > > supported.
