I don't know who thought having a multi-touch touchpad on a laptop was a good idea, but more often than not I accidentally touch it with my left hand after typing and zoom in/out of the browser when I want to move the mouse pointer.
Is there any way to deactivate the multi-touch gestures? The Synaptics driver that comes pre-installed only allows me to disable tap-to-click. I can't find any setting for multi-touch gestures, not even on a per-application level.
Open control panel, open hardware and sound, click on "Mouse". You should see the list of mouse options such as "button" "pointer" etc.
If you look at the top right corner you will see something named "Elan" with a red logo (it's hard to miss this one).
Click on it, you should see your current hardware in the panel listing ("touch board"). On this page you will find a button called "Option".
Open that and it's pretty straight forward, you'll see all the functions of your touchpad on the left side, such as zooming and rotating. Click on the ones you don't want, and deactivate them.
Try rolling back to a previous version of synaptics touchpad driver. It is a little difficult to find older drivers but this may resolve the issue. Don't try finding drivers especially for your model, instead experiment with many drivers for other models
