Q: USB port not working and old battery

Hello everyone,

 

I own a mid-2012 Macbook Pro 13" with OS X 10.11.6, that I will soon upgrade with a SSD and 16Go RAM.

But, I have a problem : my USB Ports are not working very well. I updated everything, reset SMC and PRAM, but still, it's not working.

 

It looks like they can't give enough power to my devices. When I plug an external drive which is not powered by the Macbook, it works. But when I plug my iPhone or my travel external drive, it's a bit random. Sometimes, when I plug my iPhone, it starts charging. Then stop. Then restart etc...

 

So that's why I'm talking about the "old battery". On this page (Determining battery cycle count for Mac notebooks - Apple Support) they say that cycle count is 1000 for my MBP, and I'm now on my 946 cycle.

So I was wondering if changing the battery would help me on that.

 

Thanks !

MacBook Pro, OS X El Capitan (10.11.6), null

    Ok, I just come back from the Apple Store with a new official Apple cable for my iPhone. It's working great.

    I'm going to buy an official Western Digital cable for my external drive, we will see if it was a cable problem
