macbook pro 13 inch mid 2012 ram upgrade 16gb

It's a nice machine and it's a shame if it has been bricked at the final upgrade step. The charger light shows green when it's plugged in but the little charge indicator doesn't light up (this may not have worked when I bought the machine)ĭoes anyone have any insights on things I might have missed. I can't see that anything as fried on the logic board but I am wondering after all these checks if I have somehow damaged it during the ram replacement (battery was unplugged from the board when ram was changed) Since then I have tried all the start up button combinations I can can find as well as unplugged the SSD, ram, new battery, tried refitting the old battery as well. But then all of a sudden about 5 mins into surfing the web the screen went blank and it started to restart itself. HI, i have just upgraded my mid 2012 MacBook Pro to 16gb using 2x 8gb ATech DDR3 12800 1600MHz and to start with everything was fine, booted up quickly etc. I refitted the original ram and went to turn it on again.nothing still. MacBook Pro mid 2012 13' Ram 16gb upgrade problems. The machine now just refuses to turn on after in any way shape or form. It made the beep code of the ram not being fitting correctly (3 beeps) so I shut the machine down and refitted the ram.

When fitting I made sure it was seated correctly and went to turn it on. On standard configuration, one has 4GB RAM, Intel 2.5 GHz i5 processor, and other one has 8GB RAM, and Intel 2.9GHz i7 processor. The non retina display model has 2 variations. MacBook Pro (13-inch, Mid 2012) Processor: 2.9 GHz Dual-Core Intel Core i7 Memory 8 GB 1600 MHz DDR3 Graphics Intel HD Graphics 4000 1536 MB Sn C1MNG147DV30. The one I will be reviewing is the non retina display one. I ordered 16gb of 16OOmhz ram to finish the upgrade off. 1 retina display equipped model, and 2 non retina ones. No issues what so ever and was working well just a little slow still (4gb ram)

I upgraded the hhd to an SSD and fitted a new battery. I recently picked up this machine for £50 locally.
