It’s just a matter of time before you spill some liquid into your computer keyboard or it naturally gets full of dust and dirt. When this happens keys can stick or may become intermittent. Keyboards are priced to be disposable but that doesn’t mean you should just toss it and buy a new one. Chances are you can take it apart and clean it out. The process should take about 1/2 an hour and will keep your keyboard out of the landfill.
