While desktop computers are plugged directly into an electrical outlet to obtain power, laptops rely on a battery and power cord in order to be charged. If your laptop suddenly stops recognizing this battery pack, however, it could jeopardize your ability to charge your computer and ultimately work on it at all. Mac users can reset the laptop’s System Management Controller (SMC). Apple reports that sometimes, otherwise unexplained errors pop up in the laptop’s system, including problems with the battery’s ability to charge. To reset the SMC, turn off the laptop and remove the battery. Hold down the “Power” button for five seconds and release before plugging the battery back in and turning the laptop on. Writer Bio
