Since early 2008 my MBA21 has had a CPU idle temperature of 62-67 degC, with any kind of load getting it dangerously hot (>80 degC). On a handful of occasions thermal cut-out (not sure if this is in the CPU itself or the SMC) has kicked in and halted the CPU. My SMC is at 1.14. The heat issues are apparent under Ubuntu, Debian, and Cesium, 32 and 64 bit with various kernels. Booting to Mac OS gets the fans running significantly more, although not bringing temperatures down much. I did not have any temperature issues under any OS before updating from Tiger to Leopard (which included an SMC update). Rather than the CPU, the majority of heat appears to come from the power supply area, leading me to believe that the CPU is possibly being overheated by an external heat source. Having the fans running all the time is of course detrimental to battery life, but I'm not sure that's the only reason my system constantly draws 8-13 Watts.

Status in Mactel Support: Fix Released Status in Ubuntu Release Notes: Fix Released Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Intrepid: New 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
