Jupiter is just an quick energy handler, where you can switch your needs. First of all, you have to check what you are using from the laptop services - eg. RF devices are also big consumers. You have to also check that you have the latest bios in your laptop or not, if not - mostly brings fixed ACPI too, that linux can use out. Otherwise - powertop helps to find elements that are can be controlled, but doesn't sets anything. If you start it in commandline - you get a long list about your controllable resources. Then you have to set the acpi commands that disables or limits the hw parts when the OS loads in. This is fine grain control, but first you have to make an bios upgrade, and bios setup where you can also turn off hw parts.
