I have a problem with my laptop and the touchpad. There's "something" that handles a 3-finger tap in the touchpad and causes the touchpad to be enabled/disabled (buttons keep working). This was unbelievably annoying, because at the beginning I didn't know what was happening or that this 3-finger tap was the actual shortcut for this. It was especially infuriating when this shortcut got accidentally pressed while playing games. After like a month of yelling at the screen and looking for answers, I discovered this is a "shortcut". Simply tapping the touchpad with 3 fingers would deactivate it, and doing the same would activate the touchpad again.

I want to get rid of this shortcut, but I have looked for it in the Synaptics driver without finding anything like this. Also in the control panel I don't see anything that looks like the culprit. I don't even know who is responsible for handling this shortcut, which brings me to ask this question here. Does anyone know where this shortcut comes from? Any way to disable? Any way to track the culprit and obliterate it from my laptop?

This is using a Samsung np550p05-s05cl model, with Windows 8 and latest Synaptics drivers.

I updated synaptics driver again from to and the "gesture" still exists, but i think it is not related to the synaptics driver because there's a feature to use a "3-finger press" to launch an application that "can be used". If i press 1 finger, then 2 and then 3, the application launches, but if i press all 3 finger at the same time and don't leave them at the touchpad, then the touchpad is disabled. –  Carlos May 12 '13 at 15:51

I have a Synaptics Touch Pad on my Win8 HP laptop. The way I disable the touch pad is to double tap the top left hand corner. In the top left hand corner there is a little white dot which turns yellow when the touch pad is disabled. As well as that, when it is first disabled a picture of a touchpad with a finger on it appears with a red line through it indicating disable. To turn it on again I just double tap the top left hand corner again. The red light turns off and the picture appears again showing the touch pad turning on again. You can find the touch pad settings by going to Control panel > mouse > Device settings (tab) > Click on Synaptics Lux Pad > click on settings > click on Tapping > click on the gear icon next to tapping. In there you will see the enable/disable touch pad settings.

The usual gesture for a Synaptics LuxPad (I'm not sure if this is what you have) to disable the pad is to double-tap in the upper-left corner of the pad. When disabled, a yellow LED in that corner will light up. Another double-tap will disable it.

In the Synaptic control panel, if you edit the "Tapping" gesture's preferences, you should see a checkbox to enable or disable this feature.

I don't know the specifics about your Samsung model, but on page 40 of the manual (http://downloadcenter.samsung.com/content/UM/201408/20140828131747862/Win7_Manual_eng.pdf ) it would appear Fn-F5 is a hotkey to enable/disable the touchpad.

Page 38 also mentions that gestures are configurable with one of two different control panels, depending on whether you are using the Synaptic driver or the Elan driver. I don't know what will happen if you have both installed. If you have the Elan driver installed, maybe the 3-finger-tap gesture is being handled by it.
