MacBook needing reset after sleeping

Hi everyone,

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.

Thank you!!
