Some of the FUNCTIONS expected for F1-F12 are, sudenly, not working. On this notebook, FUNCTION-F3 should mute the speaker; F4 volume control; F5 brightness control and F7 monitor swap. No one of them work. But the HOME, PAGE UP, PAGE DOWN and END functions of the 4 arrows work well.
Any ideas will be highly appreciated.
