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......?
