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):
Steps to Reproduce:
1.Install latest kernel
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.
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.
