Hi All,
I have a mid 2015 A1398 15" rMBP. It needed a new battery so very luckily, I was able to source a genuine Apple one as opposed to the many Chinese aftermarket ones.
I very carefully removed the existing battery & installed the new one. Upon starting the rMBP with the new battery, I got a message stating the the Keyboard & Trackpad was not detected & neither of them responded to any input.
I had a friend who does services Apple computers come round & have a look at why this issue was happening. He discovered that the Ribbon Cable port on the trackpad female connector was damaged as was the Ribbon Cable itself. I ordered a new Ribbon Cable & correct Trackpad.
He came round again & today, installed the new Trackpad & Ribbon Cable & carefully checked the connections were sound. However, once again, the exact same issue was occurring. My friend said the installation of the new Trackpad & Ribbon Cable was done correctly & he was very careful & thorough when doing it & confirmed that there was no damage anywhere this time. He also said the new battery itself is perfectly fine & it is not the issue.
We ran an Etrecheck & Tech Tool Pro but they did not come up with anything relating to this issue. He said that he does not have the Apple Diagnostic Tools needed to investigate further & asked me to call a AASP that he deals with as they have the equipment. However, upon calling them, they informed me that they (& all) AASP's have had to return their Diagnostics equipment back to Apple due to something to do with European regulations with Right To Repair so they could not help.
I was asked to do the Apple Diagnostics Test on the rMBP & it came with a couple of issues saying "Battery Needs Service" - code: PPT004 which I do not understand as the battery is brand new & working fine.
It also reported that there maybe an issue with the Trackpad & to press "Command-G" to get started which I did but still no response from either keyboard or trackpad? The code was: NDR001 which I looked up on Google & the results showed that is code pertains to a corrupted Trackpad but again, the Trackpad was a new one?
I read somewhere that it might be a pressure thing on the ribbon cable as not enough & this issue is caused & some have resolved by folding a Post It note & placing it under or somewhere on/under the ribbon cable and/or its connectors or something like that?
I would be dearly grateful if anyone could please kindly help me resolve this issue as I simply cannot afford a new Mac - it is just out of the question & it is only this issue causing an otherwise perfectly running machine from operating.
Many Kind Thanks!
