Before you do, it might be worth adding these to /etc/sysctl.conf: hw.acpi.verbose=1 hw.acpi.cpu.cx_lowest=Cmax The former may provide deeper boot logging of problems (not necessarily called 'error') and the latter, if applicable to your CPU, might actually run cooler at idle.

On my 12.3 system I see no acpi_dell.ko in /boot/kernel, so maybe no extra support? cheers, Ianhelp
