great way to improve battery life when using doing non intensive work
i thought that disableing core would reduce power,however upon testing my battery life went from 2:10 to 1:40
i apologize
i just wanted to contrubute to the ubuntu community because they have been so helpful to me and this command took me a really long time to find
i just wanted to make it easier for people to find so that they could use it for what ever reason.
thank you all for addressing your concerns and correcting me on my false information about improving battery life
once again i will state that by going from 4 cores to 1 core i noticed a significant decrease in my battery life
the command works nevertheless
