How to make cpu0 offline?

Question

I want to make cpu0 offline. I have dual core laptop. I can make cpu1 offline ( using offline file ) but can't make cpu0 offline. How to do this ?

Are you trying to take cpu0 offline after taking cpu1 offline, or are you trying to do this separately?
No. I want to make cpu0 offline only. ( while keeping cpu1 online )

and to disable
