what about: nvidia, sealert and hald? is there any way to make them use less power? for example: powertop suggests to do hal-disable-polling /dev/scd0 is this a safe thing to do? (i've noticed there's no hal-enable-polling ....) <div>2007/8/13, Ronald Warsow <<a href="mailto:rwarsow@online.de">rwarsow@online.de</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Justin W wrote: > Bill Nottingham wrote: >> ... >> >> 4) Report the results.

I'm curious as to know why I from <a href="http://ww.linuxpowertop.org/faq.php">http://ww.linuxpowertop.org/faq.php</a> (middle of the page) Q. I see only C0, C1, and C2. Why don't the other C-states show? A. It's mostly a BIOS thing. Some BIOS hide C3/C4 when on AC power, and others show only C3 which is really a C4 underneath when on battery. Note that the 'max_cstate:C8' value in /proc/acpi/processor/*/power tells the maximum number of C-states the Linux kernel can handle, not the number of C-states implemented in your hardware. -- Ronald -- fedora-test-list mailing list <a href="mailto:fedora-test-list@redhat.com"> fedora-test-list@redhat.com</a> To unsubscribe: <a href="https://www.redhat.com/mailman/listinfo/fedora-test-list">https://www.redhat.com/mailman/listinfo/fedora-test-list</a> </blockquote></div>
