Slackware on a Sony Vaio V505: Acpi
Working after the kernel is patched. to patch the kernel make sure you have the kernel source installed (see kernel) and change directory to /usr/src/linux
#cd /usr/src/linuxif the patch is in .gz format type:
#gunzip -c path/to/your/patch/ acpi-patch.diff.gz | patch -p1 or type the following if in .diff format:
#patch -p1 < path/to/your/patch/acpi-patch.diff the kernel can now be recompiled with AC, Battery, Button, Fan, Thermal and Processor built in. acpi in kernel 2.6.13 and kde 3.4 is much more developed, enabling automatic shutdown/logoff/cpu throttling with a gui interface. if acpi just will not work for you then edit /etc/rc.d/rc.modules and remove the # from the apm section to enable advanced power management.
