Important Information about Trackpad Climate Control 
For Your Macintosh PowerBook Computer


What Is Trackpad Climate Control?

Trackpad Climate Control is a system extension that will reduce or eliminate unexpected movements of the pointer caused by moisture on the trackpad or humidity.  The extension is designed for the  Macintosh PowerBook 190,  Macintosh PowerBook 1400, and Macintosh PowerBook Duo 2300.


Who Should Use Trackpad Climate Control?

You should use Trackpad Climate Control if you notice the pointer moving abruptly when you initially touch the trackpad or "jumping" to its previous position when you lift your finger after moving the pointer or tapping the trackpad.  

Do not use Trackpad Climate Control if you have not had pointer-movement problems on your computer.  (The extension could make the pointer less responsive when you use the trackpad.)

The extension works only with the PowerBook 190, PowerBook1400, and PowerBook Duo 2300.  


Installing Trackpad Climate Control
 
Follow these steps to install the extension.

1.  Drag the Trackpad Climate Control icon to the icon of the System Folder on your computer's hard disk.  
2.  When a message appears, click OK to place the file in the Extensions folder.
3.  Restart your computer.


Pointer Movement with Trackpad Climate Control Installed
 
The Trackpad Climate Control extension monitors pointer movements and attempts to eliminate the undesired jumps that can result from moisture on or around the trackpad.  Because the extension affects pointer movement, you may notice that the pointer is somewhat less responsive when you use the trackpad.  

Once you've installed the Trackpad Climate Control, you can turn it off with the Extensions Manager control panel (by removing the checkmark beside its name in the control panel and restarting the computer).
