Hello! I am having the same problem and have the exact same hardware as the original poster. This computer has two fans: 1 directly under the CPU, and another one in the rear which is more powerful and draws from a large copper heat sink, which I assume conducts heat from other hotspots.
The CPU fan will run fine and throttles correctly with temperature fluctuation. However, it seems as if the rear fan is not being recognized AT ALL. This is a very crippling problem, as anything that uses more than minimal processor power over an extended period will overheat the CPU and force shutdown. ** Changed in: ubuntu Status: Invalid => New -- laptop becomes too hot and shuts down https://bugs.launchpad.net/bugs/112088 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
