Lenovo X220 - DW1510 prevents shutdown and sleep

[faby1992]

My Lenovo X220 with Catalina 10.15.4 works pretty well but shutdown results in a reboot and instantly wake up from sleep.
If I disable Wireless card on bios (DW1510) the problem disappear.
If I enable "Wake for network access" in Energy Saver and AC power is plugged in, the sleep works.
I think the problem is something about power management but I didn't find a solution ?

EFI and kext are the same of this repository: https://github.com/x-t/x220-catalina-efi

yes i know, but with the previous DSDT is more or less as high sierra, with this i have to wait 5 second to open finder, something not working correctly. I tried also with a new generated ssdt but not change ?
