Notebook Boot and Lockup

I guess my laptop is not the first one to have this problem, and I have not seen many users resolving the same problems on the forum.

I bought this refurbished Envy X360 13 inch with Ryzen 5 processor (13m-ag001dx) from newegg a few days ago. I went to the HP download site to update all drivers and the BIOS (ver. F33 rev. A). I also make sure all Windows updates have been performed (up to date as of today).

Ryzen has given a lot of performance problem when it was first introduced, but now with many driver updates, I do not have any iissue with the graphics or general performance of the notebook.

The only problem that persists from the beginning (before and after all these updates), is that:

1) After long period of time eg. overnight, when I press the power button to boot the laptop, the light comes on but nothing happens on the screen, and then it will turn off on its own after a few seconds. When I press the power button again, it will boot normally.

2) After leaving the laptop in sleep mode (eg. closing the lid) for long period of time eg. a few hours, it does not wake when I open the lid. It does not wake when I press keys on the keyboard or the power button. The only way to solve this problem is to press the power button for a few seconds to do a force-shut-down. Afterwards, pressing the power button will successfully boot up the laptop.

After extensively researching the forum posts, I think both situations are related to problems with the power management controller of the laptop.

To HP rep:  please do not repeat reommendation on all the things I have already tried in troubleshooting

I have already tried most if not all of peoples' suggestion:

"the simple obvious things" like set close lid action = sleep etc etc etc

turning hibernation off with powercfg.exe in cmd

turning Windows fast start off in power options

power options -> change advanced power settings -> sleep -> allow wake timer = enabled

power options -> change advanced power settings -> PCI Express -> link state power management = disabled

all AMD and HP drivers are up to date

I have tried rolling back to older graphics driver (AMD), but no difference

HP hardware diagnostics did not find problem with any component

Windows troubleshooter for power did not find any problem

I also tried to roll back the BIOS, but there is no BIOS recovery when I press [Win}{B} + power button on boot. Installing HP hardware diagnostics and HP software assistant did not give me BIOS recovery. I cannot find any copy of previous BIOS (HP only has the latest) to try to set up a BIOS recovery USB.

*NOTE* I do not have BIOS recovery maybe because I upgraded my original 128GB SSD to a 256GB HP (Hitachi) one. I did a clean re-install of Windows on the new SSD instead of cloning it.

I also know about enabling "allow device to wake up PC" in "power management" tab of the device (in this case, the keyboard) in device manager, but there is no such "power management" tab anymore in Win 10. I tried the command line approach with "powercfg.exe /devicequery wake_from_any", but the keyboard is not on the list (nor is any other useable device).

In my research, I believe that BIOS may have significant influence on power management of the laptop. 

I am out of ideas. This is a very nice laptop and I hate to return it for refund.
