Hello all, I have this MBP and just started to experience random, brief freezing issues, before coming back to working state. Of course it's out of warranty and the Samsung SSD inside is clearly no stock. While it is frozen, nothing responds: all apps stop updating their icon, there's no BBoD, and absolutely nothing is registered in the Console. If I switch from one space to another at the same time, the translucent overlay window stays on, then disappears. Usually this lasts for a few seconds, before working again, but started occurring frequently a few days ago, when I noticed the computer wouldn't light its screen, event though it was on (fixed white LED, fan at minimum speed). Where could this "absence" issue be coming from? Bad hard drive cable? Some other software issue?
