Seriously. It *is* a hardware issue. Why else would it not work right before a fan replacement, but work fine right after the replacement. I guess that it might simply be a bad thermal paste connection between the cpu die and the heatsink; but I don't know the reason as I was lucky enough to have on site support, and got the replacement without any hassle.
So seriously, if you still have warranty, phone the support *right away*. If you don't you might also try, it seems like a design issue of the model to me. If that doesn't work, I would suggest trying to clean the fan and replace the thermal paste (note that you need to remove the mainboard to get there in the T4x0s models). As a software solution, you could try to set the "power management model" in the bios (not sure if it is called exactly that). It could help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1009731 Title: Since 12.04, CPU is overheating and powering off spontaneously under high computation load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thinkfan/+bug/1009731/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
