annoying high pitched continuous sound

[mercdv]

I've had Fedora Core 4 running on my IBM T43 for a few months now. I decided to go ahead and setup the power management. I setup my cpuspeed.conf, a lid closed event, and edited my grub.conf. After doing this, my machine emits a faint, high-pitched beeping sound that's gets even louder while on battery. It also gets louder if I turn up the cpu frequency. Anyone got any ideas? I tried searching and couldn't find anything with the terms I was using.

My cpuspeed.conf looks like this:

VMAJOR=1
VMINOR=1

# uncomment this and set to the name of your CPUFreq module
DRIVER="speedstep-centrino"

# Let background (nice) processes speed up the cpu
OPTS="$OPTS -n"

# Add your favorite options here
#OPTS="$OPTS -s 0 -i 10 -r"

# uncomment and modify this to check the state of the AC adapter
OPTS="$OPTS -a /proc/acpi/ac_adapter/*/state"

# uncomment and modify this to check the system temperature
OPTS="$OPTS -t /proc/acpi/thermal_zone/*/temperature 75"

Ok, it might not be coming from the speakers. It's hard to tell since the speakers are right beside a vent port. It could even be coming from the vent port underneath the touchpad which means it could be the wireless card. Any ideas?

use alsamixer to turn down all the volumes. See if the sound continues.
A friend had similar problem, he had a nasty buzzing sound, but only when the CPU was working more than 1%. Fixed by kernel + system update .
Don't know in your case.
