I had the same issue, with loop error "kextd stalled (AppleAcpiCpu)".
By booting with the USB key i used to install High Sierra (so with minimal kexts), it booted OK and could install the update.
Erased my SSD and reinstalled 10.13 from scratch by following exactly the guide : it solved my sound issue and everything is working on my HP EliteBook 840 G3.
Thanks Rehabman ! :thumbup::thumbup::thumbup:
Thanks for you response :-)
I did "./install_acpi.sh", I just then renamed the file "SSDT-8x0-G3-Skylake.aml" to "SSDT.aml".
I disabled TRIM via "sudo trimforce disable" and disable kext patch in Clover :

Hello RehabMan
On my HP EliteBook 840 G3, I managed to get everything working on 10.13, thanks to this guide. Everything except "output sound".
Input works : Siri recognizes my voice.
Output "should" work : I can slide the volume up and down, but no sound at all from the internal speakers.

I had your issues 2 & 3.
I don't really know what made them disappear...
Last actions were rebuild caches, install lastest Clover 4233 and do a cold boot...
The Intel wifi chipset are not compatible.
You have to change it with a Broadcom.
I bought this one : https://www.amazon.fr/gp/product/B01FOEJR9G/?tag=tonymacx8607-21
The BIOS update must have reset some settings : the "Video memory size" setting was set to 32 MB.
Setting it to 128 MB solved the issue.
THANKS A LOT RehabMan !
Hello
Thanks to RehabMan guides and efforts, I have a HP EliteBook 840 G3 (bios 01.13) running Sierra 10.12.5 with the patch for Intel Graphics (Lilu.kext and IntelGraphicsFixup.kext).
So far, everything was working fine.
I updated to the latest BIOS (01.14, released 19/04/2017), which is now...
Thank you for your guide and the awesome work !
I have a 99% working EliteBook 840 G3 on 10.12.2 for my daily use :mrgreen:
(just waiting for my compatible Broadcom Wifi/Bluetooth chipset ;))
