Enable suspend in Acer Aspire VN7-571G-71J5

[barchero]

Hello again
I thought that my last post would be the last, but i was wrong.
After discard the audio in the hdmi connection, my actual problem is the suspend option.
my cpu is Intel i7-4510U and my graphics Intel HD4400, but i don't know if this is enough information to explain me how to enable the suspend mode, because actually when i click on it, the computer shows me a black screen and i need to shutdown manually to reload the operating system.
I don't know even if this laptop model can suspend with OsX Yosemite.
Thanks anyway to read this post.

Hello RehabMan,
i've followed your guide previously with the same result.
i don't know what i'm doing wrong because DCPIManager shows me the following message when i want to see my pstates.

DPCIManager has detected a dmidecode error, and will be unable to fetch your motherboard's 
information for this task. Please exercise caution.

Here you have my actual clover configuration file, the dsdt and the ssdt-6 file because i think in the last one are all my graphics methods.

It is normal.

Tankyou man.

You need a custom SSDT for your CPU. Read at the link provided in post #2.

https://bitbucket.org/dhnguyenit/hp-probook-installer-clover-edition/downloads

Download patchmatic: https://github.com/RehabMan/OS-X-MaciASL-patchmatic.
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,

rm -Rf ~/Downloads/RehabMan
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Power management appears to be correctly configured. Your sleep problem is likely caused by something else.

Try using kernel flag -gux_defer_usb2 (with GenericUSBXHCI.kext), and always test sleep without any external devices connected (such as USB WiFi).

There are other things you can try too... but they would depend on the specifics of your sleep issue.

Man, you're wright
without USB wifi the machine sleep like a baby
but i've got a new surprise. Clover detects the hibernated state but when i try to load, the machine reboots and if i want to load yosemite i need to cancel hibernation files from clover.

Disable hibernation:

sudo pmset hibernatemode 0

And as far as USB WiFi and sleep, use GenericUSBXHCI.kext with -gux_defer_usb2... it will force the device to be handled by AppleUSBEHCI where it will be better behaved. Or you can look to see if there are updated drivers that might fix the problem. Or... get rid of USB WiFi and install a supported half-mini PCIe card.
