    What are the pros and cons of undervolting and is it generally recommended that you do it with your laptop?
    I find my laptop to be quite hot (or it may be my room... it's really stuffy in here sometimes)...
    Does anyone know how to undervolt the Z70v?
    Thanks

    There is a huge thread about it over at notebookforums.com

    Basically you use RMClock or Centrino Hardware Control to undervoltage it. Let say you have a 1.86 Ghz processor. By default, it will run let say at 1.386v. With this application you could lower it, by how much depends on each laptop. You have to do trial and error with each step. You will need to lower the voltage one stepping at a time and test it for stability. Continue until you hit an unstable point. At which point you will know the last voltage you use is good. You could set it there.

    Etc...

    Undervolting has made a big reduction in the heat generated by my W3A (maximum voltage down from 1.308V to 1.084V). As a result the maximum temperature dropped by over 10°C and there is less fan activity.

    There are no disadvantages provided you keep the normal operating voltage a couple of steps above the setting where the CPU starts to give errors. I have been running undervolted for the past two months. All you need to find is a few hours to make the initial tests.
