Oh, it's working when I close the lid, just turn off the screen and Laptop is still running.

 

But when I close the lid and connect HDMI cable - the laptop sleep as before and I have to hold the power button to reset. 

 

Oh, I just install this kexts to EFI, and my Laptop is black screen when boot into Mac. :( 

 

Can I undo and remove this kexts by terminal USB Installer? :(

@Daniel PN

I'm using the same files I uploaded in the guide that you're using, there's no issue with sleep and wake.

Do you see blinking power light when system is asleep?

When wake, if screen stays dark, try pressing Escape key to see if screen comes back on.

If you have the Intel wireless still, try disabling Wifi in the BIOS.

I have a DW1820a on this system working nicely.

 

Note:

When you sleep the system and then plug in the HDMI, it's not going to wake the system. You need to have the HDMI connected before you close the lid for the external monitor to stay on. When you open the lid, the LCD will come on as primary and then set the HDMI monitor as extended monitor.
