MacBook needing reset after sleeping
So a few months ago my computer suddenly died. I brought it to a repair shop where I was told the hard drive had finally broken down after so many years. I got a replacement hard drive and the computer has been working well, except for the following issue:
Whenever I closed the lid to put the MacBook to sleep for longer than a few hours, when I opened the lid again, the screen would remain black and I would have to hold the power button to reset the computer. This is annoying because I have to re-open all the programs, windows, etc. that were open when I put the computer to sleep. This was happening whether plugged in to an adapter or not.
I spoke with the repair guy and we tried switching "Enable Power Nap" on in the Energy Saver System Preferences for both Power Adapter and Battery. Now if I close the lid overnight while the computer is plugged in, I'm able to open it and log in without doing a system reset. But sometimes I hear the fans working hard and in the morning the laptop is quite hot so I wonder if there is a better option for the longevity of the computer than using Power Nap.
But the real issue is when the computer is operating with battery power. Even with Power Nap enabled, if I close the lid and the computer is asleep for more than an hour or so, when I open the lid the screen will be black and will not turn on without holding down the power key to do a reset (even though it seems like the computer is on with a black screen before I do the reset because it is hot and the fan is running). When I hold the power button for a few seconds to reset, the computer makes the mac awakening noise once, screen remains black, then a few seconds later makes the awakening noise again, and a few seconds later I get the apple logo with the loading bar.
I have already tried resetting the SMC using the instructions here:
My MacBook is currently running on High Sierra Version 10.13.6.
What is happening is the SMC services are going into a latched state as it encountered an issue. So now you'll need to see if you are getting an error running the onboard diagnostics! Restart your system and press the D key to enter. Let us know what the error code you got.
Given the systems age you maybe due for a new battery. Install this gem of an app! CoconutBattery take a snapshot of the apps main window and post it here for us to see 在已经存在的问题里加入图片 so we can check it out as well.

Thanks for your input. I was having battery issues previously and got a replacement about 1-1.5 years ago so I am hoping my battery is in decent shape. I have attached the Coconut screenshot.
I'm happy to try the restart but I'm not sure I understand the instructions. So should I turn the computer off, then hold down the D key, then as I continue to hold D, push the power button to restart the computer?
When exactly should I hold D?

@share5 - Shutdown the system, restart and once you see its starting press the D key to enter.

Ok I was able to run the diagnostics! It came back with a checkmark saying "No issues found".
Any ideas about what to try next?
