But in this case you get only one ac_adapter device and not the information if 
the AC Adapter is present. With libhal_manager_find_device_string_match() you 
need only one call to get the information.

Same as above. You must now check also for the key ac_adapter.present to know 
if the machine runs on battery. Btw. I could enhance hal-find-by-property to 
get more than strings e.g.:

hal-find-by-property --key <key> --bool <value>
