Leopard ¿ACPI? Problem


2 posts in this topic

Recommended Posts



my problem began when i install Kalyway Leopard 10.5.2, when i had XxX 10.4.11 everything is ok.

The problem is that when i boot with the laptop unplugged (only battery), with option -v system hangs on the instruction: ACPI:System State [s0 S3 S4 S5] (S3)


I read that the problem maybe comes from a kext, AppleAcpiPlatfom, but i think that it must boot with the kext that incorporate kalyway version.


Can i install the kext from XxX 10.4.11 version? Or maybe the problem isn't this.


Please help me, and sorry for my english!


My laptop:


sony vaio vgn-n11s

intel core 2 duo

1 gb ram

intel gma 950


wifi 3945


y creo que ya está.
