If the machine gets hot but the fan stays at minimum, one possible cause is that the SMC has been switched to manual. If this was not done by hand, it could have to do with switching between OSX and Ubuntu via reboot. I have put this line in my /etc/rc.local to prevent any such possibilities:
## make sure to use automatic fan control by default echo 0 > /sys/devices/platform/applesmc.768/fan1_manual Here is a thread about it: http://ubuntuforums.org/showthread.php?t=969183 -- WARNING: Intrepid might burn down MacBook Pro https://bugs.launchpad.net/bugs/262550 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support. Status in Mactel Support: New Status in Ubuntu Release Notes: New Status in “linux” source package in Ubuntu: Triaged Bug description: Binary package hint: linux-image-2.6.27-1-generic Testing Ubuntu 8.10 Alpha 4 64-Bit on a MacBook Pro rev. 3. Installing today's updates, the MacBook gets extremely hot and automatically goes into standby. This looks like an emergency standby caused by the EFI or something because it got overheated. Unless you put a metal plate or something under it, the fan runs on highest level at full power, which is not the usual. Is there a tool you can see the CPU temperature with? _______________________________________________ Mailing list: https://launchpad.net/~mactel-support Post to : [email protected] Unsubscribe : https://launchpad.net/~mactel-support More help : https://help.launchpad.net/ListHelp
