HD Failure and replacement cable
OK. I’m pretty sure I know the problem - and fix. I have gotten great info and advice from users here. MacBook Pro, 2012 model. HD is not recognized internally - just the NULL symbol. The user has been experiencing severe “slowness” over the past few months now followed by HD not being recognized. I suspect it is the hard-drive cable and needs replacing. I CAN mount it externally in an enclosure - although very slow! I have installed a new HD cable for this model before for the same reason for another client. I know the 2012/13 MacBook Pros has had this as a common issue. SO, I am going to order/install a new cable AND a new SSD.
I will use “Migration Assistant” to move my clients files over instead of cloning. Most of her documents are basic Word, PowerPoint, Excel… Photos (iCloud). I will also back-up to a big USB flash drive as well.
This model “officially” supported only 8 GB of memory but I have read they technically can support 16GB RAM. It has 4 right now. Certainly another 4 GB chip would help. Should I go for more? Not sure it is worth it being it is a 2012. And I am installing an SSD which should speed things up a LOT.
One more thing. The calendar is showing Dec. 2018 … and it’s late April 2018. Do I have a MB issue here? Or is that the result of that bad cable? I am pretty sure the MB Pro 2012 has no CMOS but a capacitor that would need soldering if that is the issue. That is above my pay grade. ))
THX for any suggestions or help.
#Dan … Here is screenshot of battery health using CoconutBattery as you suggested. It is reporting it as good.. unless you see something different. Thx for your help.
