* I also have to add that for a few weeks ago my keboard and trackpad was non-responsive for about 10 seconds from I touch it until I could use it. The support suggested that it was software-related rather than hardware-related. If that might have something to do with it? I re-installed my whole OS and everything was fine but I rather not have to re-install every second month because of bad software. There has to be a better solution?
