Hi all: T30 laptop here; I know there's quite a few IBM-toting folks here, so I'm tossing this message here. ACPI causes some wierd interaction with possibly a capacitor near the CPU fan which makes it vibrate at a frequency that the human ear can detect. Course, if your AC is on, you're in the office, outside, etc. you're not going to hear it or care. But, when you'd like to retreat to a quiet setting to hack on some stuff it gets trÃs annoying with this thing whining at you. (Like, you already get enough of that from others during the day...) Anyhow, found a piece here that it happens on DELL: http://seclists.org/lists/linux-kernel/2003/Dec/1037.html I notice that we config in thermal.ko statically: CONFIG_ACPI_THERMAL=y So, guess I'll have to rebuild to do some experimenting. But, anyway, if you have suggestions, comments, off-topic redirects, let me know. thanks, -- -jeff
