I havenít used laptop much as compared to the desktop PC. I am not acquainted with the controls that are different as compared to desktop PC. I had purchased this laptop from Newegg and it is still under the warranty period. It is facing a major problem related to the touchpad on it. I am pressing it and it does not respond. Even the click bar does not respond when pressed. I have formatted my computer twice thinking that Operating system that I am using must not be compatible, but still the problem persisted. So I restored the factory settings, re-installed the drivers for the touchpad and click bar. I have also tried various combinations of function keys thinking that I must have locked the functionality. But nothing has helped me so far, the touchpad still doesnít respond neither does the click bar responds when pressed. Can someone help me with this issue?
