Hello Christopher, Good news first: Updating the BIOS to v1.45 actually *fixed the fan issue.* It still stops briefly during kernel load, but resumes rotation within a second. If I run stress, the temperature sensor acpitz- virtual-0 updates within a few seconds to whatever coretemp-0 says, rounded to 10 degrees and the fan adjusts its speed. Before and after sleep/wakeup.
A big THANK YOU for taking the time to help me on this. Now to the bad news: Updating the BIOS was no easy task at all and did not work as specified on the help page. (That's why my answer took so long) But maybe some of the things I discovered can be added to the BIOSupdate help page you linked, so other users dont't have to try and fail on the same things again. Note: This may be specific to the "InsydeFlash" system, but googling it seems to suggest it is in use for many different computers. * A windows 7 system repair disc created on one computer is not bound to its hardware (after installing a DVD Burner in my desktop computer, the generated disc booted on the laptop) * A windows 7 64bit system repair disc *does not* run 32-bit applications. (InsydeFlash is a 32bit application, you get an error about a required subsystem not being available). Note that you cannot choose whether to create 32bit or 64bit discs. A 64bit installation will always generate 64bit discs. * After acquiring a windows 7 32bit installation and generating a rescue disc from it, InsydeFlash still did not start. It was missing oledlg.dll (and probably others, I'm assuming it would tell me which one it tries to load next if I found out how to give oledlg it to it). * Copying oledlg.dll from the windows\system32 directory onto the same directory as the bios update file did *not work*, it still complains about not finding the dll. * Talking to a professional windows system administrator, I was told they often use the Boot-CD from www.hirensbootcd.org, which contains a minimal windows xp. Using this boot cd's XP, I was *finally* able to run the BIOS update file and the fan works now. So maybe you want to add this boot cd to the links on the BIOSupdate page, to help future users who are running into similar problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1471530 Title: Acer Aspire 5315: Fan turns off when loading linux, resulting in system overheat and emergency shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1471530/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
