Macbook Pro 2017 (Non Touchbar Model) Keyboard not working, runs extremely slow

Hello i had recently changed my battery on my Macbook and since ive changed it the keyboard had stopped responding and it runs slow beyond regular use. I have used the diagnostics feature that my mac has and it gave me a PPN001 and a PFM006 code. i had reinstalled its mac os but then when its loading it shuts off, What do i do?

PFM006 likely from liquid damage, or possibly accidental damage if someone replaced their own battery (it is not easy to replace the battery on the non-Touchbar 2016-2017 models). The article I'm linking mentions a possibility of the Trackpad or ALS sensor/camera.

The PPN001 seems to be a power adapter issue....is the power adapter connected when running the diagnostic?


The slowness is most likely a power related issue which is reinforced by the diagnostic error.....either the new battery is bad, or possibly a cable is not connected (or a cable or connector has been damaged). The battery cable & connector for the battery flex cable is very easy to pull loose or even damage.


If this is a third party battery, then there is a very high chance the battery may be bad. The quality of most Lithium batteries is extremely poor even when purchased from a respected vendor such as OWC or iFixIt.


If this is an Apple or AASP repair, then take the laptop back & have them make things right since you have a 90 day part/repair warranty depending on how Apple or the AASP performed the repair.

Who replaced the battery? Request it be looked into, and replaced.


Record what your See:

Take a few photos of your screen (i.e. using an iPhone or iPad), and make some voice recordings describing the issues while recording a video using the Camera app.
