Runtime Power Management, v 1.0

Q: Does the integration of this functionality imply that the processor speeds available are really too great
for standard needs?
A: No. This functionality simply provides more flexibility when you use applications that require less
processor performance. Today’s world constantly offers more applications that require greater
processor performance. And while you may use these resource-intensive applications, you will likely
also use applications, such as email, that do not require full processor capability.
Q: If I have a system that supports this – can I turn it off in the BIOS without disrupting the system
configuration or the software image?
A: Yes, you can turn off EIST/Cool’n’Quiet support in the BIOS at any time with no software impact.
Doing so simply means you will not conserve power.
Q: If after the feature is turned on and runs for a while, if the system performance worsens, should I turn
the feature off before calling support?
A: Turning off the feature can be a good debug step before calling support. However, if performance
worsens after a significant amount of time, the chances of a relation to EIST is low. Testing has
indicated no noticeable performance degradation.
