Have you enabled ACPI? To do this you must add the line acpi=on to the boot line in grub. If you have tried and it does not work correctly, you may need to update your DSDT (see ACPI project on sourceforge: http://acpi.sourceforge.net/dsdt/index.php) If you are lucky someone may have already published one that works. > > The fan runs constantly and the suspend doesn't function properly > under kernel 2.4.x Mainly because when I run the suspend script, I > loose my USB mouse.

This will allow the cpu clock to be slowed down when the system is idle. This allows it to run cooler and save battery. See the section entitled "Kernel Notes" in the release notes (the default home page for Mozilla) This will get you started and point you to the docs in kernel source. Finally, you will need to edit /etc/acpi/events/sample.conf. This will allow you to execute commands when certain ACPI event occur. For example you can change the CPU policy from 'performance' to 'powersave' when the AC power is removed, etc. I am probably missing some things here, I am learning this in my copious spare time. > > note: I downloading and installed this supsend.sh script from another > source. There is no "suspend" command installed on my laptop be Fedora. > Suspend is not support in the 2.4 Kernel. There is a patch but I have not tried to apply it. I read a post by someone who did and it appears that the Fedora kernel changes make it difficult. This support is part of the 2.6 kernel. From what I understand, suspend to disk works but most device drivers have not been updated to support suspend to RAM yet. > WINDOWS XP > In Windows the fan on this HP never ran!

Once I got ACPI working and the cpu throttling installed, my laptop stopped running so hot. With the CPU in powersave, the fan hardly ever comes on unless I am doing something CPU intensive. > "The reason I like IBM is that little joystick or trackpoint. I hate > touchpads!"

Under Windows it keeps switching to some compatibility mode where the pointer jumps to the scroll bar when I use the scroll area. > Sorry, I haven't tried the builtin wireless device yet but according > to all my probing it was not detected. This area can be problematic. Mine originally came with a Wireless B card that worked fine. I later upgraded to an Atheros based B/G card and that works pretty good too. > The Lid > Closing the lid turns the screen off but that's about all it does. With ACPI enabled to can make the lid event do anything you want by capturing the event in your ACPI event script (referenced above) Of course you can't get it to suspend to RAM :( until you update to the 2.6 kernel and get a hold of device drivers that are updated to support it.
