From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4 Description of problem: There is no support for Dell Inspiron 5150 APM in kernel. Running 'apm' just reports 'No APM Support in Kernel'. Using ACPI does work (echo -n mem >/sys/power/state) will put it into suspend mode. So I'm using that and it's good enough for me. Just installed 2.6.12 - no change. Version-Release number of selected component (if applicable): kernel-2.6.12 How reproducible: Always Steps to Reproduce: 1.Install latest kernel 2.Run 'apm' 3.Get 'No APM Support in Kernel' Actual Results: No APM Support in kernel Expected Results: apm puts laptop into sleep/standby/suspend/etc modes. Additional info:
You can't have ACPI and APM active at the same time. If you want to use apm, you need to boot with acpi=off.
