I continued to use the laptop (after resume and telling me those weird 0°C) and suddenly (after some bug with an app - I think unrelated) it shut down. No warn message or anything, looking in the kern.log I got this before the shutdown:
Jan 25 16:59:32 studio kernel: [18440.303726] CPU1: Temperature above threshold, cpu clock throttled (total events = 1) Jan 25 16:59:32 studio kernel: [18440.303731] Disabling lock debugging due to kernel taint Jan 25 16:59:32 studio kernel: [18440.304215] CPU1: Temperature/speed normal Jan 25 16:59:34 studio kernel: [18442.012510] Machine check events logged After that appears the bug of the subtitle editor and then the next kernel start (I included the kern.log of that moment). The last entry from kern.log is at [18446.595247]. I ran the acpi -t and sensors as soon as I turned on the laptop and got the following: ~$ acpi -t Thermal 0: ok, 0.0 degrees C Thermal 1: ok, 65.0 degrees C Thermal 2: ok, 57.0 degrees C ~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +44.0°C (crit = +100.0°C) temp2: +51.0°C (crit = +100.0°C) temp3: +0.0°C (crit = +100.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +43.0°C (high = +105.0°C, crit = +105.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +44.0°C (high = +105.0°C, crit = +105.0°C) That value drew my attention: Thermal 1: ok, 65.0 degrees C ; but I don't know if has something to do. ** Attachment added: "kern.log" http://launchpadlibrarian.net/38374861/kern.log -- Dell Studio 1555: cannot change display brightness after a while, other hotkeys and ACPI stuff begin to fail https://bugs.launchpad.net/bugs/392812 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
