This manual page was written for the &debian; distribution because the original program does not have a manual page. The intended purpose of &dhpackage; is to find out which power management modes are supported by the system. hald(8) will call it to do just that. --suspend Is suspend supported? Suspend is a state where most devices are shutdown, except for RAM. This state still draws power. --hibernate Is hibernate supported? During hibernate the state of the system is saved to disk, the system is fully powered off. --suspend-hybrid Is hybrid-suspend supported? Hybrid-suspend is the process where first the state of the system is saved to disk -- just like with hibernate -- but instead of poweroff, the system goes in suspend state, which means it can wakeup quicker than for normal hibernation. The advantage over suspend is that you can resume even if you run out of power. s2both is a hybrid-suspend implementation. The result of the test for a certain powermanagement state is defined by the following exit codes. Code Diagnostic 0 State available. 1 State NOT available. hald 8 , pm-suspend 8 , s2both 8
