The Compaq Presario™ 1200 Notebook computer with the
Mobile AMD Athlon™ 4 and AMD Duron™ processors features
AMD PowerNow! technology.
When running your Presario Notebook on battery power, AMD
PowerNow! technology maximises the operating time of your battery,
giving you up to 30 percent more computing time in many applications
without any perceptible performance difference.
AMD PowerNow! technology consists of three basic operating modes:
■
Automatic Mode—The processor speed changes dynamically based
on the requirements of the software that is running on the system.
This is the default mode for a Notebook operating on battery power.
This mode can also be selected when the Notebook is operating on
external AC power.
■
High Performance Mode—The processor always runs at its maximum
speed. This is the default mode for a Notebook operating on external
AC power. This mode can also be selected when the Notebook is
operating on battery power.
:
■
Battery Saver Mode—The processor always runs at its lowest power
consumption state to extend the life of the battery. This mode can only
be selected when the Notebook is operating on battery power.
To maximise your battery operating time when changing power
sources (for example, from external AC power to battery power), you
must install the AMD PowerNow! application to allow your Notebook’s
processor to switch speed settings automatically.
To install the AMD PowerNow! application, follow these steps:
1. Locate the AMD PowerNow Setup icon on the Microsoft Windows
desktop.
2. Double-click the icon with the left mouse button. The AMD
PowerNow! application will now automatically install.
3. Once installation is complete, your Notebook will either reboot
automatically or prompt you to click on the OK button in the dialogue
box to restart your Notebook.
Your Notebook will now automatically switch speed settings when you
change the power source, maximising operating time of your battery.
To customise the AMD PowerNow! settings, follow these steps:
1. From the Windows desktop, click Start, point to Settings, and click
Control Panel.
2. Locate the Power Options icon in the Control Panel.
3. Double-click the icon with the left mouse button. The Power Options
Properties dialogue box displays.
4. Click the AMD PowerNow! (tm) Technology tab.
5. Under the Plugged in heading, select the default operating mode for
the Notebook when using external AC power.
6. Under the Running on batteries heading, select the default operating
mode for the Notebook when using battery power.
7. Click the Apply button to accept the changes, then click OK to exit the
Power Options Properties dialogue box.
The AMD PowerNow! settings of your Notebook have now been
customised to suit your preferences.
