An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you. This bug has been automatically closed as part of a mass update. It had been in NEEDINFO state since July 2005. If this bug still exists in current errata kernels, please reopen this bug. There are a large number of inactive bugs in the database, and this is the only way to purge them. Thank you. |
Description of problem: After the laptop is on for 20 or 30 minutes, the cooling fan goes on and it stays on all the time. The laptop seems hotter than it does in Windows XP, but that's just a subjective feeling. (This is a new laptop, and I can't say how it would have been in FC2. On another Dell laptop with FC2, the fan did go on and off to drive the temp down) The ACPI online docs say there should be passive and active cooling modes, but I don't have them here. Does the fan thing happen because the cooling mode is set to critical and there is no way to change it? # cat /proc/acpi/thermal_zone/THM/* <setting not supported> cooling mode: critical <polling disabled> state: ok temperature: 46 C critical (S5): 90 C Version-Release number of selected component (if applicable): I don't find any laptop-mode info in FC4, so I think this is a kernel bug? # rpm -q kernel kernel-2.6.11-1.1369_FC4 I'm using the centrino based wireless ipw2200 version 1.04, not the one distributed with the kernel, as well as the NVIDIA GO 5200 video with 64Meg RAM. How reproducible: Steps to Reproduce: 1. Turn on laptop 2. The fan goes on, whether or not the system is plugged in 3. Actual results: fan stays on Expected results: fan should go on and off Additional info: In the mailing list archive for fedora-maintainers, I see some talk about RPMS for laptop-mode-tools and such, but I don't see any results! I notice they talk about the laptop power issues in the context of STR--Suspend To Ram. STR does work with the acpi script I'm pasting in below. If I suspend the PC, and then restart, the fan does not kick in right away. It waits a little while, then never goes off. #!/bin/sh # do not got to suspend mode if some command fails! set -e rmmodules () { mname=$1 if grep $mname /proc/modules ; then /sbin/rmmod $mname fi } # if network is up, shut it down! if [ -f /var/lock/subsys/network ] ; then /sbin/service network stop fi # remmod all problematic modules rmmodules tg3 rmmodules uhci_hcd rmmodules ehci_hcd rmmodules hci_usb rmmodules ipw2200 rmmodules ieee80211 rmmodules ieee80211_crypt #preventive: sync echo mem > /sys/power/state # after waking up, move to terminal 1, this give some time to graphic card to get into sane state chvt 1 sleep 0.5 # change into gui terminal, graphic card is ok at this point chvt 7 #load modules /sbin/modprobe uhci_hcd /sbin/modprobe ehci_hcd /sbin/modprobe tg3 /sbin/modprobe ipw2200 /sbin/service network start /sbin/ifup eth1
