Hi there. I have been having this problem for the past day or so. Every now and then, the screen on my MBP goes black for about a second or two, then comes back to normal. This has never happened in the past so this is really odd to me. Strange things have been happening to my MBP lately. My battery life only surpasses a little over an hour now as well and my battery is perfectly healthy based on the tests I've run. Can anyone help me with these issues?
