Can I either replace LSI with new ones or add some? Im not trying to deceive anyone by replacing them. I only have one thats red-on the trackpad. I replaced the keyboard & backlight, harddrive, RAM, & battery as an upgrade and that one indicator turned slightly when i was cleaning it. No corrosion anywhere. I am not even opposed to leaving that LSI and just adding a new one. Im not getting rid of this machine. I want the lsi for my own benefit.
