i remove the SS02 in Hackintool, regenerate the usbport.kext, and place in E/C/K/Other no change.

if I disable only bluetooth, no change ... still no good wake-up.

wake up is ok only if wifi is disabled in bios.

BrcmPatchRAM2.kext and BrcmFirmwareRepo.kext are in clover /kext /other , not in L/E... can be the problem?

or the kext for wifi on dw1820A  used are not the correct one ?

BrcmFirmwareRepo.kext needs to be in /L/E with BrcmPatchRAM2.kext

If you want them in clover kext, you need to replace BrcmFirmwareRepo.kext with BrcmFirmwareData.kext

Try removing the wifi card DW1820A but not disable wifi in BIOS

if the dw1820A  is removed, sleep and wake up are working properly, the only small problem is the USB key connected when laptop go to sleep, , I receive a message at wake up : usb was not eject properly...., just disconnect and reconnect and it is fine. after reconnect the dw1820A ,  same trouble.

 

anyway , I need a new combo card :-( ..... Dw 1560 or dw 1830 or again DW 1820A......?

Without hesitation, I would recommend DW1560. DW1820a's are hits and misses and also seems to depend on specific models are well. I tested it on my E7450 and E7270, both hang/freeze/lag after 15-30 mins of usage, while it's fine on 7490.
