I've always had this doubt and some clarification would be very welcome. On Mac notebooks with non-removable battery (such as the MacBook Pro 2014), is the SMC reset by disconnecting the battery and pressing power for 5 second as is done on older Macs with removable batteries (such as in cases where Alt or Command keys are not working).

Here's the Apple article on SMC reset: https://support.apple.com/en-gb/HT201295


No, on Mac notebooks with non-removable batteries you "press Shift-Control-Option on the left side of the built-in keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds", exactly like stated in the support article you linked.

  • Thanks for your answer, I've modified my question, I meant in cases in which any of the SMC buttons isn't working. – Antonio23249 Mar 12 at 23:48
  • I'm a technician and I'm resetting SMCs every day, when the keyboard isn't working, we usually press the power button for 5 seconds after disconnecting the battery as was done in old Macs. I can't be sure if this is really doing anything, that's why I'm asking. – Antonio23249 Mar 15 at 6:59
