My keys are not working properly. They (hotkeys, enter, backspace) will only work if I hold down the control key. Keys that only work properly without the aid of control key are F3, T and Y. I tried using an external keyboard but I still have the same issue. Sometimes the Ctrl key holds down itself even without pressing it.
Functions like F2 and F9 will only work if I press Ctrl+Alt+Fn. As of now I am using on screen keyboard to type this message. This happened before. After three weeks the keys worked properly. After quite sometime the same problem happened again. I already tried reformatting my unit but the problem still exist.
