Power Schemes

[gary]

I’m not understanding the workings of the power scheme settings. I have a HP
Pavilion dv8000 laptop and they tell me that the processor can adjust to a
lower speed if you have the setting at Max Battery. How does it know that you
have selected Max Battery? You can type in any name of your choosing here,
what triggers the processor into operating at a slower speed?

Furthermore I don’t understand the default settings if you take a look at

And scroll down to say the Portable/Laptop settings when on AC current. You
have the hard disks turning off after 30 minutes. This is impossible because
the system standby has already shutdown the hard disks 10 minutes earlier
(after 20minutes).
Again when in the Max Battery power scheme, this time using battery power.
You have the hard disks turning of after 3 minutes, but they are already off
when system standby kicked in after 2 minutes. Am I not understanding
something here?

Gary, the hard drives do not turn off in system standby. I don't have a
laptop but I know there's software that will do that to a desktop CPU.

Ofcourse it does, it will shut down the drive and the monitor and put the
system in a low power state. Take a look at

below is an excerpt of that discussion:

Putting Your Computer on Standby or Hibernate
There are two basic options for putting your laptop to sleep when you're not
actively using it, but don't want to completely shut it down—Standby or
Hibernate. Standby is energy conserving, because your entire computer
switches to a low-power state. Devices, such as the monitor and hard disks,
turn off and your computer uses less power.

Gary, you are entirely correct. I just choose never to shutdown my
drives. So for me they never shut down.
