You're working on your laptop, and all of a sudden, the "I" key stops responding, or a whole section of your keyboard stops responding to keystrokes. Or, worse yet, the keyboard cuts out entirely. While this can be a hassle, particularly when you have work due, there are a few things you can try yourself to get back to the job at hand.
Hold your laptop upside down or at the very least at a 45- to 75-degree angle from horizontal and give the laptop a good shake. Sometimes crumbs from working lunches or your last snack break can get stuck under the keys. This is more of a problem the older your laptop is, but it's worth a shot even on a new laptop to see if you can fix the problem quickly.
