From ioreg, I don't see anything wrong. You're probably lacking a compatible WiFi device though...

Make sure BIOS is set as post #1 suggestions. And make sure ACPI is patched based on current BIOS you have installed. There is instructions in post #1 for repatching.

yes i have intel wifi which doesn't work and i just got the new lap 2 days ago so won't change it for now
and i'm using usb tethering from htc one m8 and working great out of box and very very fast and reliable connection

about bios, i'm sure it's the same as in the first post and i just formatted again my yosemite partition and cleaned efi partition and reinstalled it from scratch and patched every thing again and every thing works great except this glitch of sleep

but as i said before i'm now sure it's hardware related as the system itself works without any problem when connected to hdmi in the same time that internal screen is flickering very bad
so i don't think anymore it's driver related
and also in my previous laptop there wasn't such problem and even sleep was making my system works better
so really bad luck and i can't call lenovo to change this new one as it works perfect in windows while the other one was flickering very bad in windows

so one question can you please give me the name of manufacture of your screen as i'm sure that i have a different one

new update about screen problem ..
i can get the screen flickering now without sleep .. just by going to dispaly and changing resolution
so it's clear that somehow after sleep, the resolution is changed and i think it's edid problem as i'm sure that our display is 15.6 not 15.5 as my previous y5070 was showing it as 15.6 and screen was working great after sleep
and this also explains why there is no flickering on tv screen because its edid is right

so i hope that u can tell me how to inject edid and give me your edid to compare it with my one to check

i was getting to this point because i was reading this thread http://www.tonymacx86.com/yosemite-laptop-support/161591-intel-hd-graphics-5500-need-some-help.html and saw your comments there and they was having some problems and it was related to edid and screen resolution

will try to figure it out and hope u can help me

thanks in advance

Because you never filled out your profile (as per guide), no idea even what screen you have...

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

For single system, suggest requested information (all 6 details) is in your profile.

At any rate, was wondering if it was UHD or 1080p...

No known issues with 1080p. Maybe you can describe better what you're seeing.

yes my screen is 1080 that's why there should be no issues with it ..

the problem that every thing works perfect and screen resolution is 1080 without any problem .. all this till i press apple .. sleep
then after waking the lap again, the screen will have alot of artifacts and flickering and this leads to slowness in the system
but then i figured that the sytem itself isn't slowing because when i connect hdmi i can see that every thing is very smooth on the tv screen while it's very slow on the internal screen and hazzy with alot of flickering

then also i figured out that i can replicae the same problem by just changing resolution in display tab in settings
that's why i thought that the internal screen edid got messed somehow and screen resolution got changed after waking from sleep

and also my previous y5070 with exactly the same specs wasn't have any problem like this

and the only difference between the 2 laptops that the older one was recognized as 15.6 screen 1080 in apple..display tab while the new lap showing as 15.5 1080
and i think that screen info is being read from edid so if this one has messed edid, thats's why it shows as 15.5 not 15.6 as the older one

hope it's clear and hope if someone gave me his edid to compare it to my one and also look at apple..display and telling me if it's 15.5 or 15.6
and i'm not talking about the one in apple..overview which showing as macbook pro 15inch .. i knew that this one is related to smbios
i need the one in the tab just beside it

thanks for your patience

and the only fix to get my internal screen working perfect again is by restart
and my internal screen is made by samsung

my fear that windows 10 is the cause of my edid corruption as alot of alienware laptops have broken screens after windows 10 although i got 8.1 back now

All Went well until final config.plist
I'm using a UHD lenovo. After performing this step . my lenovo is not booting into hackintosh.
while booting is stuck at boot screen and starts to flicker and then completely stops working.

Please clarify my doubt.

Did you patch IOKit?
Did you set DVMT-prealloc?
Did you use the correct config.plist?
