Windows 10 blank login screen

[anon(8895690)]

Hey, 'name is Matej.

I have a problem with my Acer Aspire 5943G. I just upgraded from Windows 7 Home Premium OA to Windows 10 Home, and then updated Windows 10 until there were no updates showing. A couple problems appeared which I was able to fix but not a particular one; When I startup the laptop it all goes smoothly but when it gets to the login screen (clock with the background), my screen's backlight suddenly turns off. I can still see the faint screen info if I shine a bright light in it. If I restart it, it fixes the problem though. This is rather frustrating as I cannot expect when it will happen (right now it happened when I turned it on from hibernation, sometimes it happens with a normal shutdown and startup). My GPU is ATI mobility radeon HD 5650.
Also having a sound issue. I can get the sound to work through headphones, but not through the speakers.

Any help you can give and share, is greatly appreciated.

I am glad to have found someone going through the same issue, I was very excited about this upgrade until my screen went blank on every start up....also looked Acer's website and it says that Aspire 5943g is not compatible for upgrade so not sure whether this can be possible....I had to go back to windows 7 until any solutions.

Hm, looks like this is a startup bug with Windows 10. If I start up the laptop from no power, the screen is dark (no backlight) but then if I restart it, when I get to the login screen, the screen's backlight starts working. Can you try testing this technique, vs16? Maybe you'll get it working.
I hope Microsoft fixes this as it's really frustrating to have to startup the laptop then restart it again to get the backlight working (especially with being on a HDD, everything is so slow, I'm used to SSD speed).

Edit: This bug also appears when waking up from hibernation mode and from sleep. And even uninstalling the video drivers or choosing which to only work doesn't help either.

EUREKA, kind of....

I solved the issue temporarily by going into BIOS and switch the graphics tab from switchable to discrete. This has solved the issue for me. Let me know if it works for you too. But I still hope, microsoft fixes the switchable graphics startup issue.

Hi Matej,

I have tried this but still had trouble, it took me roughly 2/3 start ups for the screen to appear. I had the same issues as you.

Just Tap CTRL KEY

I have a blank screen after the Windows logo. I tried hitting the Ctrl key and entering a password, but that didn't do anything.
