------- Comment #18 from [email protected] 2009-02-24 17:05 ------- (In reply to comment #14) > How does /proc/acpi/ac_adapter.../state get > the correct state? > because an ACPI method (_PSR) is always reflecting the actual ac status. when you read it, ACPI ac driver invokes this ACPI method, and get the correct AC status. But un/plugging AC adapter is another story, when you un/plug the AC adapter, OS doesn't receive a notification, which is usually an ACPI interrupt. So the HAL doesn't know this change, and it won't invoke the _PSR to get the new AC status. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
