Hey guys, So around May this year I upgraded my 2012 MacBook Pro with an SSD (using the OWC data doubler) and I added more ram. Around 3 months ago or so my computer started turning off randomly when moved or pressed in certain areas (not always though, and sometimes it just shutted off without me doing anything). I opened it again yesterday to check if there was some loose cable or something not plugged right but I couldn't find anything wrong. After that the computer seemed to be fixed as it wouldn't turn off when shaked, moved, etc. Or I thought...because that night the computer shutted off and I couldn't turn it on again until I shook it a little bit. This happened again today but now it won't turn on even if i shake it. I tried resetting the SMC but nothing happened. Hope anybody knows what can I do, thanks guys! EDIT: It turned on again, but I had to bang it really hard against the table.
