Well, searching and searching for a solution I missed the main place to search: kernel list. And this was reported on 2005.
http://bugzilla.kernel.org/show_bug.cgi?id=5289 Quoting from there: The issue is that ACPI first tries to read device power state from _PSC method, if this is unsuccessful, it evaluates device state from the power resources, defined for this device. In your DSDT the _PSC is defined with 0x00 value, and never being updated later, so the device state is always reported ON. With this patch the things should work as expected. I have it running right now with the dsdt patched, and working great so far. Temperature is a bit higher but stable, and the fan are reported, at least, correctly. I've attached the DSDT file that i'm actually running on. I'll confirm after a few days of work if this resolves the problem. Maybe it's a clue for some other people with other laptops having the same one. Just be sure to put it on /etc/initramfs.... folder in uppercase (DSDT.aml) , use the update-initramfs option and use the acpi_no_auto_ssdt on kernel load, as described in the method to use custom dsdt files from the wiki. ** Attachment added: "dsdt.dsl" http://launchpadlibrarian.net/13974384/dsdt.dsl -- laptop fans doesn't work sometimes https://bugs.launchpad.net/bugs/72775 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
