Hi, I have a MacBook Pro 2016 Touch Bar (A1706) which had a faulty screen. I changed the entire display but the laptop was not turning on or responding at all. Upon further inspection I noticed that the battery connector did not have the locking tab to secure the ribbon cable - it must have fallen out as I found it in the chassis.
Is the locking tab required? Would this prevent the laptop from turning on? I tried using the power adapter and the laptop still did not turn on. Should it not at least turn on if the power adapter is connected?
As I have the clip, is it possible to somehow fix it back to the connector or is it not repairable once it pops off?
Please see the photo to get a better idea of the locking tab.
