[tesla-dev] [powertop bug]:Battery info not shown when running PowerTop through VirtualBox

[Darrin Johnson]

I ran  "kstat -m battery" on Solaris (on Vbox 1.6 on MacOS) and got the 
following output:

module: battery                         instance: 0
name:   battery warning                 class:    misc
	crtime                          47.413763103
	enabled                         0
	low capacity threshold          0
	snaptime                        2215.84236619
	warn capacity threshold         0

module: battery                         instance: 0
name:   power                           class:    misc
	crtime                          47.413758137
	snaptime                        2215.842849596
	supported_battery_count         0
	system power                    AC

Is that why "no ACPI power usage estimate available" shows up?
