Problem:

Since Last Mojave Security 10.14.6 Update May 26, Computer show no video after sleep/close lid, have to press the power button for seconds to restart and work find. After restart it show a crash report.

The problem also appear when I make a fresh boot - no video and it restart two times, two chime sounds. I have to wait 5 to 15 seconds before i press the power button for 10 seconds to boot normal. no crash report

If I select Sleep from the menu make the problem

Machine specs:

Searching the problem found many users with similar problems but with no specific solution.

a temporary fix will be to download GFX Card Status and have the option "integrated only" on.

It seems the culprit is the GPUs, the NVIDIA one doesn't always get recognised, and when it does it's instant shutdown. It also can be Apple did (one of many for this model) a recall because of a manufacturing error and failing GPUs. but i dont know if is my case.

Help me Ben Kenobi, you are my only Hope!

A big greetings on this Pandemic Cookie!

I will wipe the Drive and make advance hardrive format, but if someone have a clue a solution, a suggestion etc, please let me know.
