1. About this document

When I first started the switch from APM to ACPI I didn't realize the kernel needed to be patched. My

problem (insanely loud fan) was fixed just by upgrading to 2.4.20 (Debian packaged kernel with an earlier

patch from acpi.sourceforge.net) . Unfortunately after the first upgrade I wasn't able to halt my computer

without using the power switch to power−down my computer. It wasn't until later that I realized I had an old,

ineffectual ACPI patch. This HOWTO was written to summarize the install process for myself, and hopefully

help others who are also having a hard time finding information about ACPI. Please note: the main article

outlines The Debian Way of doing things. There is also generic information in the Appendix B for those of

you who prefer ... the generic way.
