takeawaydave Posted December 31, 2019 Share Posted December 31, 2019 Dell laptop in signature sleeps fine but one annoyance is that when it wakes from sleep I am usually presented with a black screen. This I usually resolve by opening and closing the laptop screen a number of times under the screen "registers" again and I can unlock and move on. Are there any known fixes for this problem ?
