Can somebody please help me with my laptop keyboard? Some keys are not working particulary 7, U, J, M? I already tried some key combinations such as Fn + scllck; Fn+NmLck. Probably those combinations are not compatible with my laptop. My laptop model is Toshiba L650 - 15G. Please kindly help me with my problem. Thank you so much!
I suspect that your keyboard need to be replaced.
You can type "OSK" into the start program tab in Windows. Then you can click on the letter/key image on the OSK (On Screen Keyboard). If the OSK works then you have a mechanical problem with your keyboard.
