You’ll need to use a USB keyboard and mouse/trackpad to check your system. Basically, you need to start the system and press the D key to enter into the onboard diagnostics. Let us know what errors you get if any
In addition, you should install this gem of an App CoconutBattery to check your battery as often the battery swells up pressing on the cables which in turn interferes with the signals. Post a snapshot of the apps main window here for us to see.
If you have the needed tools I would take the bottom cover off to physically inspect the batteries cells if they looked puffed up you really need a new battery.

The last drive I did was a few months ago, I put in an OWC X2 SSD on a 15” retina system. Frankly, I personally haven’t really encountered that many issues with OWC. I think it’s been only one bad which I had gotten by the customer quite a few years ago, OWC shipped me out a fresh one quite quickly.
I will say many people have a hard time dealing with the OS recovery part as Apple jumped from HFS+ to APFS file system, Apple forgot to manage its recovery servers so when you try to do a fresh OS you get the older HFS+ OS which doesn’t offer the needed NVMe driver, so you get nowhere! I would need a few peoples fingers and toes to count how many people here have had this issue. But that’s not OWCs fault!
I’m sure the amount of returns is staggering! And I bet there is nothing wrong with the drives!
Which is why I always preach setting up a bootable OS installer thumb drive for your current OS, I think I’ve got a good dozen of them now setup and that’s what I use always! It’s even faster that the internet.
I also like sticking with the real McCoy! They are still available new! You just need to know where to look.
I just don’t like these M.2 adapters as Apple still has a few signal lines which are not compatible with the adapter/M.2 SSD setups. These are housekeeping services which fail once the drive is overly loaded up.
Basically, as this is a booting drive some files can’t be moved. This is the old shoe cobblers dilemma! You walk into the shoe store and you need a new heel for your shoe, but clearly the cobbler can’t fix your shoe while you have it on! Hence the dilemma!
Apple has a few tricks here to deal with that but without the data line it doesn’t work. Now the OWC and the Apple custom SSDs have these lines.
Don’t misunderstand, I love M.2 SSDs it’s Apple who failed us! But not sticking with a standard and if something was missing in the standard they failed to get it done!
