Hi all,

I am trying to check an information about the thinkpad x121e model with
an AMD Fusion E-450.

I am considering to acquire one for linux kernel development purpose but
I have to check it has a specific feature for what I need to do.

Please, could someone confirm there are several C-states supported in
Linux for this laptop ?

In order to check:

for i in $(find /sys/devices/system/cpu/ -name "state*"); do
	echo "=================="
	echo $i
	cat $i/usage
	cat $i/name
	cat $i/desc

And also, I am looking for dynamic C-state, that is, when the laptop is
plugged, there are less c-state and when it switches to battery mode, a
new c-state appears.

So roughly, giving the output for this command when the laptop is
plugged and on battery, would suffice.

Would someone with this hardware be kind enough to confirm this
information ? :)

Thanks in advance
