I have been unable to ACPI working correctly in fc1. I am running running 2.4.22-1.2115 and also .2129 with the following errors coming up during boot. ACPI: AC Adapter [ACAD] (on-line) ACPI: Battery Slot [BAT1] (battery absent) ACPI: Battery Slot [BAT2] (battery absent) ACPI: Power Button (FF) [PWRF] ACPI: Sleep Button (CM) [SLPB] ACPI: Lid Switch [LID] ACPI: Processor [CPU0] (supports C1 C2, 2 performance states) ACPI-1120: *** Error: Method execution failed [\_SB_.BAT1.SEBI] (Node c1334a80), AE_AML_UNINITIALIZED_LOCAL ACPI-1120: *** Error: Method execution failed [\_TZ_.THRM._TMP] (Node c1332580), AE_AML_UNINITIALIZED_LOCAL It isn't seeing the battery that is installed. It does show when charging. I think it did work a few times because it showed % of battery remaining. Now it just shows 0% battery and gives me warnings about battery running low. I am unable to dual boot anymore, but it was working fine in windows. Any thoughts? Steve
