Really wanted to "like" this computer but it kept randomly and unexpectedly shutting off without warning.  Did the whole review of device manager, restore to factory condition, etc.  Even loaded and upgraded to Windows 10 Pro hoping it might fix the problem.  ACER offered to ship it back to factory for repair at no cost but it would be about a 3 week total turnaround time.  Easier to return to Amazon and bought a Dell instead.
