  It started, late one summer evening... This laptop is pretty much lightly used, was package well for shipping, and only sat on my desk after arrival.  description:  a computer monitor with a silver base and black border with a photo of a desert landscape. white lines dance across the surface. I see other people have tried steps listed as to remedy the problem, to no solution. One person on Apple's forums even received an entirely new (to them) machine, and it still persisted, so I'm thinking it's a software problem.  After restarting several times, I restarted into the diagnostics tools. I had dead pixels on my old MacBook Air and I dropped that more than once - no flickering. How can a laptop that simply sat for a few months flicker on the display? [ I forgot to make a video while the issue was happening. If it starts again - hopefully not - I will edit one in ] The stripe is only on light backgrounds.  Anything darker than white does not see the stripe. ...

So, either the monitor doesn't go back more than 5 months, or this machine was returned and wiped and sat in storage for months until I bought it. The numbers on the far left indicate a health score - 10 is best. The problems make the score start at 5.  An update between September 1st and 15th caused some things to not update, including an Intel driver, but we're all good now . You'll see IntelAudioService and "Stopped Working" under summary. That is probably the one issue I have truly had with this laptop - The audio will randomly stop.

Here is the part you want to see - Troubleshooting! Question: Do trunks form between SW1 / SW2 and SW2 / S3? Remember: VLAN trunks are the highway that every bit of information can pass upon, no matter what VLAN it came from. When the VLAN frame gets closer to its destination, it will travel on roads only avaliable for that VLAN. The packets for SW1/2 so far show DTP and PAgP. Now, PAgP is Cisco-proprietary Etherchannel, but DTP is for trunking negotiation between switches. Wait!
