The solution to this problem is usually to use i8kutils. I think you would try this solution and post here the results. After that, if the problem remains, a bug report would ask for fixing i8k to support Dell Inspiron 5521.
i8kutils solved this same problem in my Dell Inspiron 15R SE-4670. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1172294 Title: Dell Inspiron 5521 overheating To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1172294/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
