Jeremy's Temperature CSM shows the internal temperature of your PowerBook, as returned by the power circuitry inside. It can also show the battery temperature, which is returned by the teeny microprocessor located in the battery. This module has little useful purpose, but it's fun watching how toasty your PowerBook gets inside.
Compatibility
This module is known to work on the PowerBook Duo, 190 series, 500 series, 1400 series and 5300 series. It will hopefully work on any future PowerBooks as well, but it uses an undocumented feature that can change at Apple's discretion.
Installing the Temperature CSM
To install the Temperature CSM, it must be placed in the Control Strip folder inside your system folder. Unfortunately, the Apple system software isn't smart enough to automatically realize that it should go there, so you must drag it to this folder manually.
1) Open your System folder.
2) Copy the Jeremy's Temperature CSM file to the Control Strip Folder in your System folder.
3) Restart your computer.
Configuring the Temperature CSM
When the Control Strip first appears after restarting, the Temperature module should be displayed, as shown below:
ﾂ
The internal PowerBook temperature and the internal battery temperature are displayed. The appearance of the module is controlled by the module's popup menu. To make the menu appear, click anywhere on the Temperature module, and the following menu will appear:
ﾂ
Display as Celsius (Fahrenheit and Kelvin)
You can change which temperature scale is used, between Centigrade, Fahrenheit and Kelvin.
Display temperature scale
While it takes up a little more space, you can have a letter showing the current temperature scale displayed. A "C" is shown for centigrade, a "F" for fahrenheit, and a "k" is shown for Kelvin.
Display internal temperature
When this option is selected, the internal temperature only is displayed.
Display battery temperature
When this option is selected, the battery temperature only is displayed.
Display both horizontally
