I have a Dell Inspiron 7559 Signature Edition laptop which I've owned for almost an year now. As of two days ago, the touchpad stopped clicking. You can still tap to click and multitouch gestures still work, but you can't physically click on it anymore. Pressing down on the pad used to make a click noise and the bottom was separated as left click and right click. The right click side presses in without a sound now, and goes in further than is normal. Please advice
