Because a lot of Dell Alienware computers are having a similar problem.
And who the hell are you to tell me what to do?
this is what worked for me. After tearing my hair out all yesterday and by using the narrator, I was pretty sure everything was working... I just couldn't see anything. Thanks to a couple of suggestions here, this morning, I took my laptop and went to plug it in to my TV via HDMI to see if I could get a display on a second screen. I turned it on and strangely, my laptop screen came to life. Given my battery doesn't hold much charge I raced back to my study and plugged it back into mains power.
AS SOON AS I PLUGGED IT IN THE SCREEN WENT BLANK.
Unplugged it and the screen came back on. I bought myself enough time to update the graphics card driver but that didn't help. In the end what worked for me was changing the power settings from High Performance to Entertainment. I did try Battery Saving but that was worse and I lost my screen for a few seconds even on battery (I think).
Probably not going to be much help for desktop users but I would definitely try unplugging to see if you can get your screen showing.
I found the permanent fix for my Dell Vostro 3550. Attach second monitor and display will comes on second monitor.
Go to Dell Website and download the latest version of bios in mine case the latest one was A12. Install the latest version.
Once its installed unplug the external monitor and its all sweet. then you will see the external monitor settings as well.
Hope it will help.
Thanks guys for all the information.
Keep up the good work.
I have been battling the black screen no cursor problem since Friday. I tried taking out my nvidia gtx 760 and using my onboard graphics card but that didnt work. when i found this thread i thought id try to turn off the multi-monitor setting in my bios, to my surprise it was already off! this gave me the idea to turn the setting back on (still using onboard graphics at this phase), plug in my tv (via hdmi) and my dvi monitor,windows 10 downloaded without a problem!! i then just turned off my computer,reinstalled my video card and moved both cables to the video card. i have restarted multiple times and it works like a charm!!
Hey everyone just joined in to share the solution to my particular problem.
I have a Dell Inspiron 15 laptop (n5050) and began the update to windows 10 yesterday in the night. Everything was going like I think it was supposed to, only that approx. around 1 hour and 30 minutes or 2 hours the screen of my laptop got black that was it. I left it on all the night (thinking that it might be still on the installation process) and woke up this morning to see it was the same (and then I started to get worried).
After reading your suggestions, I restarted the computer twice and tried to write my password to "log in" but it didn't work. Now, what worked for me in this case was a solution mentioned back in this thread to "put the machine to sleep and then turn it back on". I closed my laptop (to put it on sleep mode) and when I opened it back up after 3 minutes of black screen, windows 10 boot up and I was able to sign in and everything (heck, I'm writing from the machine right now).
Not sure if this solution it's Dell exclusive, but you could give this a try guys.
for the people who have blackscreen while installing with no cursor.
all i had to do was reinstal windows 7/8, dont update just instal and when you are in windows for the first time, dont instal drivers but begin the windows 10 installation immidiatly! maybe it will give blackscreen for a minuut but dont turn off your pc. just let it go, so reinstal, upgrade done!
