Hey,
i testet with system Pw . I apply Sleep, Laptop go to sleep , but the Desktop is showing ( freeze ) . No Wake up , nothing, No Wlan no Ethernet. I thinking about a D520 Bios flash. The best way i think, a modified a08 dsdt.aml. I dont know ^^..... Im despair !
Edit : I testet again, now Wakeup works , but a lot of grafikBugs ^^hmpf !
