Black Screen after Sleep

Hi Mark,

I sincerely apologize for the technical troubles you have experienced with your New Dell computer.

Reset BIOS to default. Restart the computer and tap F2 at Dell logo.Now tap F9 to “Setup defaults”.

If the issue persists, run diagnostics on the computer. Restart the computer as soon as you see the DELL logo, tap until you see the one-time boot menu. Now select Diagnostics.

Let me know the status.

Unfortunately neither tapping (nor holding) F2 nor F12, when the Dell logo appears after restarting, brought up any special menu for me.

Regards,

Mark

I finally managed to get into the F2 menu by rapidly tapping F2 about half a dozen times from immediately before the Dell logo appeared. I reset the BIOS to default. I also did a Diagnostics check and it found nothing.

Before resetting the BIOS, I updated Windows fully, and then installed the latest Intel HD Graphics driver and also the chipset driver from the Dell support site, using my service tag. Just before typing this I set my laptop to sleep and left it for over an hour, and it came back on fine - no problem.

I will post on here, if I have the problem again.

Regards,

Mark

P.S. I found this seemingly related Microsoft Support article - http://support.microsoft.com/kb/2850674

It just happened again. What should I do?

I have the exact same problem. It seem only to occure in situations where the machine is in sleep mode for a longer time. There seems to be no problem if I wake up the machine up immediatly after a few seconds or a minute. I'm using the new XPS 12 with  the 4th generation Core i7 so the machine is brand new.

I can't get it to stop. I've searched the internet and tried everything suggested. Please let me know if you find a solution. I'm away from home for a few weeks, but if it's not fixed by the time I get back, I'm left with no choice but to send it back to Dell for fixing/replacing. A huge inconvenience. A huge disappointment.

Same problem here. I was on holiday after receiving laptop and now is out of return period. Can't even create a recovery disk!!! Spent too much time and none the wiser.

As for getting into Bios screen, hold and keep on holding F2 then power on. Found it hard way :emotion-12:

I'm having the same issue. Here's how it goes: When my laptop is left to sleep for quite some time, and I press the power button, the power indicator and keyboard keys will light on. Then the power indicator light will switch off but the screen is still blank and the key lights are still on. Then I have to force shut down and start again, with all my progress on work gone.

I don't want to replace my laptop as I have many things inside already and I find it troublesome to have to reset everything. Also, I get pissed off when I forget to save all my projects and put it sleep, then I wake up the next day losing everything. I know this is an old post but please do something about this issue. 

if you don't game, then it's better to completely uninstall and disable the AMD graphics.  

sadly, I game -.-

I have the same problem on my brand new Dell Insperion 7437 notebook. Can someone please advise on a solution? Should I send it in for repairs?

Congratulations! You just posted a comment to a more than three year old thread. In the meantime I got a refund for my XPS 12 because of issues with the screen, replaced it with a Lenovo Yoga 2 Pro that I handed over to my parents a year ago because I'm using a Surface Book right now. So that was a blast from the past receiving the email to the reply on this thread. On a serious note: Have a watch on the dates before replying to a thread.

I had the same problem my last Dell. After sending it if for service 7 times over 12 months and no resolution I requested a new Dell or refund. I received a new Dell. I have purposefully not placed it in sleep mode as in the past this seemed to trigger the issue. I've had it for 4 months with no issue, until today when I placed it in sleep for approx 3 hours and it occurred again.

Perhaps a path: Laptop was connected to another display - while laptop screen was dark, the second display was live and allowed me to restart the laptop. Fixed it although acknowledge that this is likely to recur continuously.
