To keep things exciting, it depends on the laptop. Generally, though, the problem here is that some laptops require ACPI to make the fan go, so if you turn on APM, no ACPI, and therefore no fan. Mine (a Sony Vaio U101) requires ACPI to make the fan work _properly_, but luckily it's "fail on" -- without ACPI, it runs at full blast all of the time, which is at least less dangerous that the alternative. -- Matthew Miller mattdm@xxxxxxxxxx <http://www.mattdm.org/> Boston University Linux ------> <http://linux.bu.edu/>
