Before undertaking any of the more time consuming solutions below, these are a few fundamentals to get you started. | |
- | * Restart your Mac. Uncheck the box to "Reopen windows when logging back in." This ensures a problematic app or session does not reopen. |

* [[How to reset NVRAM and PRAM on a Mac|Reset the PRAM or NVRAM|new_window=true]]. These are terms for a small amount of memory which contains some pre-boot settings for the Mac. Clearing changes made may restore keyboard function. | |
* [[How to reset the SMC on a Mac|Reset the System Management Controller|new_window=true]] (or SMC). This can clear any incorrect or bad startup settings or resolve issues where your Mac is stuck in sleep. | |
* If you have a Mac with [link|https://www.ifixit.com/News/14776/apples-butterfly-keyboard-continues-to-plague-macbook-owners|“Butterfly” style key switches], they are [link|https://www.ifixit.com/News/10229/macbook-pro-keyboard|especially prone to this sort of failure]. Apple introduced a [link|https://support.apple.com/keyboard-service-program-for-mac-notebooks|Service Program to address these issues]. Check to see if your model of Mac is included. Be aware that the program only covers your device for four years from date of initial purchase. | |

== Battery Swelling == | |
- | Lithium ion batteries have a tendency to swell with age, repeat overcharging or underlying issues with the device. This swelling causes internal pressure which may be exerted upward into the keyboard and trackpad. |

* This may be difficult to notice if the onset is gradual, but some keys, or the trackpad may be difficult to press, the space bar especially is prone to this. | |
Ultimately, it may come down to an issue with the keyboard itself. This is typically a result of liquid damage, but can occur regardless. MacBook keyboards are often extremely difficult to replace by themselves. They are riveted to the top case in most models. This results in two approaches to this issue. | |

This is how Apple handles the repair internally. The assembly includes the palm rest, and keyboard at a minimum. It may also include the battery, trackpad, speakers and touch bar depending on model—hence the weighty price tag. |

You'll need patience and some ingenuity to get the [parts|Mac Laptop|keyboard|itemtype=keyboards] out and mount it again, but it's definitely doable if you're up for a challenge. |
== Logic Board Fault == | |
- | The logic board is the hub for the vast majority of a MacBook’s functionality. Any number of the small components on the board may have failed or become damaged. Logic board fault is a safe assumption of cause if nothing else on this page has worked. |

* Check for obvious signs of a board issue - burned or cracked components, liquid residue, corrosion or bend. If there are signs of liquid, there’s still hope your Mac can be resurrected. | |
* If you don’t want to undertake this yourself, your local repair shop may be able to help! Ask them if they offer this sort of repair, or can recommend someone who does. | |

+ | Despite holding an ACMT certification (or maybe specifically because of this), the MacBook I’m writing this on is cobbled together from at least three separate machines and the touchpad is entirely the wrong color. think this says everything you need to know about me as a Mac technician. |
