Dell Latitude 7480 - High Sierra: Any how-to?

Recommended Posts

Hello!
Thanks very much @catmater for help!

I have Dell 7480 laptop with intel 7600u CPU (HD620 graphics). And i have LTE modem Sierra EM7455 (DW5811e) (MBIM mode with open COMports)
After change wifi to DW1830 - its work well.
DSDT don't patched.

Sleep - doesn't work
Touchpad - doesn't work 
USB-С (thunderbolt3) - doesn't work
CardReader (RTS525A PCI-E) - doesn't  work

But here anybody said that you need patch DSDT and SSDT.
Could you help me patch DSDT?

This issue with touch pad is qite strange.

I have Latitude 7480, i5 6200.

Initially it took me a month to get my DSDT patched for I2C to get touchpad work with Voodoo I2C kext + High Sierra.

I have updated bios + reinstalled High Sierra because of sleep issue (laptop dosnt go to seleep instead it just hangs). The reinstallation did not solved the sleep issue, but touchpad works straight ahead. I have not made any DSDT patches for I2C nor for GPO pining. Just have placed I2C kext it to the Clover forder,  and get working touchpad.I wonder if its because of bios update or because of new releace of High Sierra.
