MacBook Pro 13” 2015 running slow
Hi, I recently bought two MacBook Pro’s, one with a broken screen and one with no power.
I tested the one with the broken screen on an external display and found no issues.
now I have transferred the logic board into the MacBook with no power it is running incredibly slow, it takes minutes to boot and minutes to load safari. I have ran it with the battery unplugged, this made no difference. I have also tried two different SSDs with no difference so I’m sure it’s not a software issue. I have all the parts from the other laptop still. I’ve also reset SMC and VRAM. I’m struggling to install any software to do any tests.
the fan also appears not to run, however in a hardware test it runs
It was running slow in the internet recovery mode aswell.
Any help would be much appreciated.
