Please help!

At hp 450g2, everything works well, less wake up after sleep. The screen is black.
No command is active. I have to start again with shutdown button.

Thanks in advance

Thank you very much for the answer.

I attach kestcache output.

Many thanks.

You might try different ig-platform-id values.
You can set it with OVERRIDE_IGPI (look at existing examples such as SSDT-4x0-G1-Haswell.dsl).
Keep in mind that Broadwell ig-platform-id values can vary with LMAX requirement (must look at framebuffer data to find out what PWMMax is assumed). You can override the LMAX with OVERRIDE_LMAX (again, look at existing examples).

Thank you very much for your work.

Might be best to start with ig-platform-id that starts with 0x1616.
I took a quick look at the kext binary, and see two:
0x16160000 (LMAX=0x1499)
0x16160002 (LMAX=0x056c)
 
Thanks for reply.
Where can I find Lmax?
I have limited OS and language notions.
 
Thanks for reply.

I already told you what they are for those two ig-platform-id values.
The PWMMax is specified in the framebuffer data associated with the ig-platform-id.
For example, looking at the data for 0x16160000, we find 0x1499:
00 00 16 16 00 03 03 03 00 00 00 01 00 00 F0 00 00 00 00 40 99 14 00 00 99 14 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 08 00 02 00 00 00 30 02 00 00 01 05 09 00 04 00 00 00 04 00 00 00 02 04 09 00 00 08 00 00 82 00 00 00 FF 00 00 00 01 00 00 00 40 00 00 00 06 0B 00 00 00 00 08 00 00 00 00 00 05 00 00 00 00 00 00 00 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 C8 00 00 00
 
Hi.
I do not know how to do it. I tried, it does not work.
Curious is the same 450g2 laptop, I have two SSDs: one disk0 works perfectly OSX El Capitan, ver. 10.11.4, and on the second disk1 goes Sierra without wakeup.
I wanted to try High Sierra but, I do not know, I think stop here for the moment.
Thanks!
Best regards
