My PS4 likes ejecting disks when in sleep mode. Will probably replace it at some point but not too awful. Tried restoring OS and tightening manual release screw (without proper screwdriver admittedly). I'm just ejecting my disks after use right now :/
It's a really loose screw though by design. I'm not sure whether to turn it with or without full vertical pressure. Maybe somebody knows (it's "springy").
I just turned the screw about 1/4 of a turn. No 'full pressure', just enough to get the screw to move.
