Hi Dhariya,
I am Sumit, an Independent Advisor here to assist you.
He did something that is very generic - he just forced all the processors to be on every time, rather than Windows managing the same on demand.
It would not make a performance boost though, however you can use high performance plan, that is not a problem, but it would constitue more power.
Processor speeds are locked usually for laptop, and cannot be increased.
Hope that helps.
