(Synaptics)
Synaptics TouchPad Enhancements driver for laptops touchpads. The Synaptics drivers are used by a majority of laptop manufacturers. There are many problems associated with the Synaptics drivers : excessive amounts of CPU used by the drivers, inability to install specific software packages (mostly packages which use the Wise installer), and outright freezes of the laptop where often the only solution is to remove the battery as it is impossible to turn OFF the frozen laptop. Not all laptops exhibit these problems.
Recommendation :
If you experience any of the above, go to our drivers page and download and install the latest Synaptics drivers for your laptop (if you are not sure which one you should download, consult with us). This solves the problem in a rather low 30% of cases. If you still have the problem after having updated your Synaptics drivers, and you need to install software, do a Ctrl+Alt+Del and do an "End Task" on both SYNTPENH and SYNTPLPR prior to attempting to load the software you are trying to load (note, this will disable the TouchPad, so make sure you plug in an external PS/2 mouse before starting your PC and killing these two processes) alternatively disable both SYNTPENH and SYNTPLPR in Startup Manager. If your problem is freezes, and updating the drivers does not correct the problem, then the only solution is to remove the Synaptics drivers via the "Add/Remove Program" icon in the Control Panel and then see if Windows 98SE/ME/2000/XP will be able to handle the TouchPad with their own drivers. In most cases they do, particularly with Windows ME and XP, but you do lose the ability to use the middle mouse button if you have one. Removing the Synaptics drivers and having the TouchPad handled by Windows always corrects the freezing problems in our experience.
