Dell Inspiron 1520
The touchpad buttons have stopped working while I can still use the touchpad for screen navigation as well as the vertical and horizontal scrolls are working correctly. I can even click by tapping on the touchpad.
The touchpad buttons had worked for few seconds in between but later have stopped working completely. I have tried re-installing the touchpad drivers. Also did a factory restore. But the issue sustains.
Not sure if its a software or a hardware issue. Please advice!
Try safe mode (F8 before Windows loads). If the buttons work there, it's a driver problem. If not, replace the palmrest.
