I'm still observing how it behaves and playing around. Generally, the EAPD bit should stick because of the *pop* that is being issued, but sometimes it gets disabled after exactly 35 second after the audio stream (produced by the *pop*) stops. To reenable it would require a 2nd PIO. Also, you don't actually have to go to sleep now, you can just send the machine to sleep (from menu) and interrupt it after 5 second. Same thing when you lose jack sense after 2nd PIO.

By increasing to 600ms, works well with two PIOs while using LID sleep under c53 f1 version AppleHDA. test more...

 

EDIT:

Apple>sleep, takes one PIO,  ^_^

With LID sleep there's this difference about how the machine is transitioned to sleep and awoken. So by the time you open the LID everything has initialized already and it requires a bit longer delay than Fn+Esc or Apple-Sleep. I myself prefer hitting Fn+Esc then closing the LID... everyone has his ways though, so we must account that. But so far with the headphone amp poweron-poweroff trick and lesser delay in between checks it seems to work pretty consistently. At least from what I had tested for past couple of days. Hiccups still happen, but going to Apple-Sleep and interrupting it solves majority of them without the need to reset or sleep cycle.

now im testing with C53, ccf6+hdac53. all sleep mode are taking PIO #1 without problem at the moment im not facing with lose audio stream after 35s. i will continue testing..... upd later.

Takes 2 if you do a longer sleep cycle (like leave it overnight) or wake with LID and walk away when it prompts for password and then it will go to that fugue-sleep state again.. I still Ned to determine if the headphone event really helps, or its the lesser time interval in between checks.

UPD: i thought that everything was working fine but i didn't notice that i sent to sleep with menu option before i posted. like you said, everything work fine after send it to sleep through menu, including all sleep mode and the 35s.

Made something new this weekend .. not sure if 14R users can use this, but 3450 user having a laptop that ships with illuminated keyboard certainly can.

I've yet to finish it, but it works for the most part as it is ... I'm *that lazy* that I need my keyboard to enable and disable illumination for me :)

i saw the registers are the same as 14R, also there are three steps to adjust by pressing  Fn+F6, basically it should work, i will test when i get home. BTW, good job TW :)

I just though that 14R being an entertainment -oriented machine won't come with backlight keyboard from the factory but I knew for a fact that you can install one, guess I was wrong. I've pushed some changes. Do we need a hid tickle event (alt or control press and release for example) on a  virtual keyboard so that the illumination level would change by itself, without the user input? Well, I suppose you wouldn't know what I mean until you try the kext.

actually it doesn't install by default but motherboard reminds power support port, so i buy a backlight keyboard from XPS installed, works fine without modification.

 

just download it and compile, works well. I turn off backlight then restart, it automatically turns on with step one, defined in the ssdt-9 while it's night now.

And i know what you try to say, but how to use a virtual keyboard do u mean keyboard viewer ? on the other hand, pressing Fn+F6 directly is more effective compare open keyboard viewer i think.

i think it's fine now. it doesn't need to add a mute for automatically action. because if i want to change, just press Fn+f6 will be fine (personal view).

What I mean is that currently if you are not working on your laptop and time to enable backlight hits the keyboard won't illuminate until you touch touchpad or press a key on the keyboard. What i m asking whether its fine or I should simulate press of Ctrl or alt when this transition from on to off or from off to on happens? Personally I think its pointless, since you only need the backlight when you are typing.. But someone may have another POV.

Thanks for testing though!

Ultimately my idea was to invoke camera module and somehow determine the luminosity around. It's possible, but complicated.. but the thing with this approach is that the LED from the camera would always be enabled and on vostro its white and really really bright, so it would be uncomfortable for your eyes when you work.

i compile and installed but for now it useless for me until i get a backlit keyboard. it make me ask you a question, if i buy a backlit keyboard, is it compatible with my 14R system? because i search on ebay for it and he say if my system 14R didn't ship with backlit wouldn't work.

Oh those bastards hid the connector lol. But you can certainly dremel the plastic out and use the zif, just make sure to tape the plastic that may potentially cut the flimsy ribbon of the backlight connector.

 

On a related note.. Ive spent grand majority of yesterday debugging the ITE keyboard/EC controller that is seen on that picture. If you have access to a live distribution of Ubuntu mind checking if this would work for ya? Use sudo perl dell_ec command in terminal to read from the embedded controller.

wow, i see hwsensor log shows unknown ITE chip. but now i haven't one i can do a test. 

 

Edit:

Aha, it seems your script needs to correct with " instead with ”. or it doesn't excute.

This is all info i get, all commands runs well, i see my laptop gets 90w ac adapter and 88% battery healthy.

cool, thanks for testing! still need to add led sense for cap, num and scroll and thats pretty much everything I was able to debug.

the AMD board sure has more temp sensors when compared to intel-only boards..

this along with the fan control algorithm will probably end up as an all-in-one IT8518E fan control and info app for windows at some point.

 

yeah, there may be differences as quotes go.. my ubuntu installation was picky so I had to use  ”

tw, i tested your perl script and all command work well for me too. there are a few smart quotes and perl does not support smart quotes as string delimiters, my system is intel-only. like you said AMD board has more temp sensors than intel-only. i compared it with zprood log and saw less temp sensors.

 

Zprood, thanks for the pic, i will check later and let you know.

 

 

Update: I found it, now i will order a backlit keyboard. thanks!

      Install macOS 10.15 Catalina on Gigabyte P55-USB3 with Radeon RX 580 graphics card using a USB device created with the createinstallmedia command and Clover as bootloader. Instructions to install macOS 10.14 Mojave on this computer are almost identical, replacing Catalina app with Mojave, so this article is suitable for both versions of macOS. The Gigabyte P55-USB3 motherboard (and some others from the same brand with the P55 / H55 chipset) have made it easy to build a hackintosh and install macOS since 10 years ago. Although it is an old motherboard, the behavior with Mojave or Catalina is very good after changing the classic hard drive (HDD) for a solid state drive (SSD).

      Components of the hackintosh
      Gigabyte GA-P55-USB3 motherboard: P55 chipset, 1156 socket, ALC892 audio, Gigabit RTL8111D network, DDR3 RAM Intel Core i5-750 processor for socket 1156: 4 cores, 8MB cache, clock rate 2.66 GHz Fenvi FV-T919 wireless + Bluetooth card: PCI-Express, wifi is ac type, detected by macOS as Airport and Apple Bluetooth Radeon RX 580 8 GB graphics card: works OOB but with a few details to be considered, it has its own article.  
      Previous requirements
      Install macOS Catalina app in /Applications folder USB flash drive with at least 16GB prepared from Disk Utility with MBR partition scheme and formatted as Mac Os Plus (on older Gigabyte boards like mine, USB sticks partitioned with GUID scheme instead of MBR usually hang the system when booting) Recent version of Clover (I have used r5117) Recent versions of Lilu (at least 1.4.4) and WhateverGreen (at least 1.3.9) to fine-tune the behavior of the graphics card Recent version of RealtekRTL8111 (I have used 2.2.2) FaceSMC version 6.26-322 (newer versions disable automatic mounting of USB devices on my system).  
      Create install USB
      Run this command from Terminal (assuming the target device is called USB):
      Bash: sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/USB /Applications/Install\ macOS\ Catalina.app
      Clover must be installed on the USB memory, I choose the following options:
      Bootloader > Install boot0af on the MBR CloverEFi > CloverEFI 64-bit SATA BIOS Drivers, 64 bit > Recommended drivers > FSInject + SMCHelper + XhciDxe BIOS Drivers, 64 bit > File System drivers > ApfsDriverLoader Install RC scripts on selected volume Optional RC scripts > Disable sleep proxy client.  
      You have to copy 4 kexts to the EFI/CLOVER/kexts/Other folder of the USB device: FaceSMC 6.26-322, Lilu 1.4.4, WhateverGreen 1.3.9 and RealtekRTL8111 2.2.2. Regarding the config.plist file, the most significant is:
      Boot > kext-dev-mode = 1 in Boot arguments GUI > Theme embedded, EmbeddedThemeType Dark, Screen Resolution 1920x1080, Preboot in Hide Volume Graphics > blank, nothing is checked except if foxbox solution is used to have more than 2 connectors enabled RT Variables > 0x28 in BooterConfig and 0x67 in CsrActiveConfig SMBios > iMac14,2 Sytem Parameters> Yes in Inject Kexts and check Inject System ID.  
      Install macOS Catalina

      Boot from the USB device and choose Install macOS from Install macOS Catalina. The installation program runs until the PC restarts. Here choose Install macOS from HDD (the name of the volume you are installing macOS on). With RX 580 graphics card, the screen goes black in this second phase of the installation, it is a phase in which the user has nothing to do until the PC is restarted so you can let it work until the Clover menu again. You have to choose Boot macOS from HDDto boot the installed system from the hard disk, the screen is recovered and you can configure the account and the initial options. From this moment the screen works fine.

      In summary:
      Boot from USB > Clover menu > Install macOS from Install macOS Catalina > screen works fine Boot from USB > Clover menu > Install macOS from HDD > black screen Boot from USB > Clover menu > Boot macOS from HDD > screen works fine.  
      Install Clover and kexts on the hard drive

      Clover needs to be installed on the disk where we just installed macOS. Options are the same as when installing it on the USB memory. You also have to copy the 4 kexts (FaceSMC 6.26-322, Lilu 1.4.4, WhateverGreen 1.3.9 and RealtekRTL8111 2.2.2) into the EFI/CLOVER/kexts/Other folder on the EFI partition of the disk. And review the config.plist file remembering the comments for the USB.

      If everything goes well, the computer starts from the hard disk with a running copy of macOS Catalina.

      Radeon RX 580 8 GB graphics card on macOS High Sierra (as of 10.13.6), Mojave and Catalina on the P55-USB3 board: excellent performance with acceleration (Metal) OOB, no need for drivers (kexts), with 3 drawbacks, one has to do with the boot of the operating system (a solution is proposed), another with the number of rear connectors enabled (a solution is proposed) and another that only affects to one phase of the Mojave or Catalina installation (without clear solution for now).

      I have placed the XFX AMD Radeon RX-580 P8DFD6 8GB Triple X Edition GDDR5, 256BIT, DVI + HDMI + 3DP graphics card on a 10 year old motherboard (Gigabyte P55-USB3) in order to update the hackintosh to 10.14 Mojave and 10.15 Catalina because the card that I have used in past years, Nvidia Geforce GTX 750 1GB, has stopped working after 10.13.6 High Sierra since this was the last version for which Nvidia published the alternate web drivers that were necessary for the card to work well with graphic acceleration.

      The new RX 580 card needs considerably more space than the old one although it fits perfectly in an ATX case, and requires an additional power connector. It has 2 big fans that most of the time are stopped, at least in my case. In macOS it works perfectly, even with Metal acceleration, without additional drivers and without extra settings in Clover. But it has drawbacks that I comment below.

      Alterations during startup

      During the boot of the operating system, when the screen goes from the basic driver to the AMD driver, 2 artifacts appear randomly, they are very short in duration (from one to a few seconds):
      Very short flashing white screen that may or may not be accompanied by purple lines The fans runs for a few seconds (the noise is clearly audible). This behavior is solved with the installation of 2 kexts, Lilu and WhateverGreen. Lilu is an extension created by acidantheraand vit9696 among others whose function is to help to patch kexts, processes and libraries during macOS boot. It is accompanied by specific plugins for the task required, for example WhateverGreen that injects necessary patches for certain AMD, Intel and Nvidia graphics cards. It is mandatory to have both extensions together, one of them separately does not correct the problem.
      I have installed Lilu 1.4.4 and WhateverGreen 1.3.9 in the EFI/CLOVER/kexts/Other folder of the EFI partition and artifacts have disappeared. Remember that these 2 extensions are not necessary for the card to work properly, if you tolerate those very brief distortions of the screen or the noise of the fans running for a few seconds, you can live without Lilu and WhateverGreen.

      Note: authors recommend that when using Lilu and WhateverGreen with Radeon cards, NO graphic settings have to be added to Clover (Inject ATI, etc.).

      Note: these alterations, especially the brief white screen and less frequently purple lines and fan noise, are also seen in Windows and some real Macs with the same card.

      Alteration during macOS installation

      Boot from USB > Clover menu > Install macOS from Install macOS Catalina > screen works fine
      Boot from USB > Clover menu > Install macOS from MacintoshHD > black screen
      Booting from USB > Clover menu > Boot macOS from MacintoshHD > screen works fine.

      In the first and third stages, screen works fine. In the second stage the screen goes black although the installation continues. The user has nothing to do at this moment so you can leave the PC working until the Clover menu is shown again, the screen is recovered, the initial account options can be configured and you can enter into the newly installed system with correct resolution and acceleration.
      This behavior is not corrected even by placing Lilu and WhateverGreen into the USB device. At least in my case I have not found a solution for it. Yo can install macOS perfectly with that drawback of not seeing how it progresses during the second phase of the installation.

      Only 2 connectors of the 5 available work

      This card has 3 Display Port (DP) ports, 1 HDMI port and 1 DVI port. In my case, only 2 DP work, those that are further from the HDMI connector. It is enough if you use a single monitor or 2 monitors that can be connected by DP. But if you want to have 3 or more connected devices or some of them only have HDMI, it is necessary to enable the 5 connectors or at least 4 of them since the DVI is obsolete and does not allow resolutions as high as DP and HDMI.
      User foxbox has proposed a solution in a thread titled [Solved] Sapphire RX 580 Nitro + SE | black screen on HDMI and DVI. Must inject from Clover a modification to the Orinoco framebuffer (which is used in the RX 580 card) so that the 5 connectors lack a fixedly assigned address and, instead, receive it dynamically. This change is made from the KextsToPatch section of Clover. Read the post from foxbox.
      This has to be accompanied by 3 changes in the Graphics section of Clover: Orinoco in FB Name / Inject ATI / 5 in Video Ports. I have tested this solution in macOS Catalina and it effectively enables the 5 ports of the card but, since I only use 1 monitor, I have removed it and I am with Lilu and WhateverGreen.

      Bonjour,
       
      Je rencontre un souci depuis la dernière maj supplémentaire catalina 10.15.4, même chose pour la 10.15.5 aujourd'hui : après le début de l'update, lorsque le pc redémarre, je ne vois pas le volume d'installation dans les volumes de l'écran de boot clover (v5118). j'ai juste Preboot dans les volumes cachés au démarrage, et j'ai essayé de les afficher, le préboot de l'install apparait bien mais le boot n'aboutit jamais par ce biais. du coup, je suis bloqué en 10.15.4. Auriez-vous une idée du problème ?

      Perhaps it was the first NEC (Lenovo) Lavie Z HZ550 to install hackintosh. I hope more people who like Lavie Z series can experience Hackintosh at HZ550. She is really great.
       
      I found HZ550 & HZ750 on the Chinese website, which is amazing. It weighs only 790g, 13.3 inches, and the standard 2k screen, which is too attractive to me. I am a Hackintosh enthusiast. I think HZ550 or HZ750 with MacOS is the best Unfortunately, the Lavie Z series is not listed in China, only exists in the Japanese and American markets, and in the Japanese market is the NEC brand, while the American market uses the Lenovo logo.
       
      Fortunately, I got an HZ550 from Taobao. Yes, not HZ750. In comparison, HZ750 has more touch screens and 360 ° flip. These are hard to attract me. More importantly, HZ750 is about 200g heavier than HZ550 That's why I chose HZ550. Well, because he is only 2,000 RMB.
       
      The specific introduction can refer to NEC Japan official website:http://nec-lavie.jp/products/hz13b/
       
      The HZ550 hardware list I obtained:

      Advantages: small size, light weight, 2K screen, 8G memory, 512g SSD, keyboard feels good, and wireless network card can be replaced, which is unimaginable in today's thin and light books.
      Disadvantages: The sound is small, almost the same as the mosquitoes.
       
      Ok, bragging is over!
      In order to use the wireless network, I changed the wireless network card from inter 7265 to BCM94352ZAE. Some people called it DW1560. It is uncomfortable that in China, this card and his elder brother DW1830 were hyped to a high price of 480RMB. of. Fortunately, I bought it early, and this card is also very stable under win10, and there is no high delay and outage. The hard disk should be PM951 of Samsung, not PM981, which is lucky.   Before installing Hackintosh: You need to prepare a 16G U disk, SanDisk is not a rough choice for making MacOS installation disk, I used the latest MacOS Catalina 10.15.5, got config.plist from Rehabman, and put together an EFI, the latest version of clover and kext drivers. Thanks to Rehabman and the developers of the Black Apple community. I do n’t like that OC team very much.
      Make an installation disk: If you have a computer running MacOS, you can use the command line to make it, if you do n’t have a computer running MacOS, you can try VMware, I know that the insanelymac forum allows discussion, or use ether to write the image to U disk, use the EFI I provided to boot into the installation process.   BIOS setting: Press F12 at boot to enter the BIOS settings, Tab switches to "Security-Secure boot", set to "DISable", this is what we need, and switch to "Boot -Boot devices", set the U disk as the first boot item You can directly enter the clover guide interface, please follow it for google it.
      It is worth noting that the remaining space of your EFI partition needs to be greater than 200M, otherwise, the disk format will be wrong. In addition, the format partition format is APFS, do not choose to encrypt, your data is not valuable, at least you must have this awareness of Hackintosh, the file safe is also the same, do not enable, do not use to find your mac, otherwise, change the machine, OK .   Fortunately, no additional ssdt patch is required. All the patch functions are implemented through clover. The flat Apple is turned on. This is to solve the problem of the flower screen. You can find a solution yourself.
      Experience your black apple, this will bring a better experience than MacBook Pro. EFI_HZ550.zip
