Computer peripherals and mobile devices have similar troubleshooting workflows. Knowing how devices should work and troubleshooting common problems—part of maintenance—are important when preparing for exam CompTIA A+ 220-1001. Through this course, learn to troubleshoot post beeps codes, basic input/output system (BIOS) time settings, and booting to an incorrect device; to resolve issues relating to power such as overheating, smoke, and a burning smell; to troubleshoot common hard drive issues such as read/write, slow performance, failure to book, drive not recognized, and OS not found. Next, learn to investigate Redundant Array of Independent Disks (RAID) issues and failure conditions; to use self-monitoring, analysis, and reporting technology (S.M.A.R.T) error technology; how to fix video or display issues such as dead pixels, artifacts, color patterns, dim image, flickering, distortion; to troubleshoot issues with display, batteries, power, indicator lights, connectivity, touchscreen, performance, and GPS. Other issues: common wired and wireless network problems such as limited connectivity and unavailable resources, such as the Internet, printers, e-mail, Internet Protocol (IP) conflict, transfer speeds, and service set identifier (SSID) not found.
