A few nights ago, I went to boot of my Mac and it showed a green battery display for a few seconds before booting up normally. I hadn't seen it since. Today, booted up just fine. Had to go do something so I closed the lid and came back about 10 minutes later. When I opened the lid, I had this striped screen of red, greenish lines. It was the entire screen area. I never shut down, this was just re-opening the lid. I did a hardware diagnostic (using D on startup) and it came up nothing found, but would diagnostics detect a video issue? If it is a video thing, is it able to be repaired/replaced? I think if the attachment is enlarged, it will show the pattern.
Appreciate any input!
