How Will Eist And Cool'n'quiet Impact Hp Customers - HP dc7608 - Convertible Minitower PC Frequently Asked Questions Manual

System Properties - Cool'n'Quiet
The System Properties window displays current processor speed on computers installed with a
Cool'n'Quiet-capable processor and Windows XP Service Pack 2 that are using an adaptive power
scheme. The following images illustrate a drop in processor speed for an AMD Athlon 64 3800+ system
(2.4-GHz) under throttled conditions with Cool'n'Quiet enabled and disabled.

How will EIST and Cool'n'Quiet impact HP Customers?

HP tests its images and deliverables for EIST and Cool'n'Quiet compatibility. These tests include:
•
Applications bundled with HP bPC computers
•
Operating system images bundled with HP bPC computers
•
Peripheral drivers bundled with HP bPC computers
•
Samples of popular applications and games
By default, the Home/Office Desk power scheme that is shipped with the HP image is non-adaptive.
This means that under normal circumstances, a system will not see any power saving benefits with an EIST
or Cool'n'Quiet capable processor. HP resolves this issue by making the Home/Office Desk power
scheme adaptive using the Microsoft supplied powercfg.exe utility. During unbundling, if the system con-
tains an EIST or Cool'n'Quiet- capable processor, the Home/Office Desk power scheme is modified.
