Aspire 5610-4179 Orbicam and Touchpad Problems

I have an Acer Aspire 5610-4179 laptop which was recently shipped back to me from the factory. I had been experiencing several problems, all of which were detailed and only some of which were fixed. I love having it back so much, though, that I am reluctant to send it away again. Some of the problems I am running into deal with the Orbicam camera and the touchpad. I have tried updating the drivers for these, but that doesn't seem to solve the problem. The camera still says that it is not plugged into a working USB port even though it's an internal camera; the touchpad works for moving the mouse, but tapping on the touchpad does not act as a mouse-click anymore. In addition, the volume and DVD control buttons on the right side of the keyboard no longer work. Is there any hope of fixing any of these problems from home, or does the computer absolutely have to be shipped back to the same people who wouldn't fix them before?

 

Does anyone have any suggestions for me at all? I'm willing to try almost anything!

 

The webcams of ACER notebooks are connected internally to a USB port therefore it's detected as an USB device. Do you have your chipset driver installed? What OS do you use?

Again, what windows? Do you have any touchpad software installed? Synaptics, ALPS..?

Perhaps the Launch manager has to be installed in order to work this?

 

Chipset Drivers are installed. The touchpad is a Synaptics v8.2.19.0. Anytime we try to reinstall the Acer Orbicam or the MS LifeCam 1.4 (carefully following the instructions), we get a registry error - code 19.
This is a year after the original request, but the computer is used heavily for work and time for minor repairs has been short or non-existant (as you know). Thank you for any time you can apply to this. Let me know what other information you need.
