Windows 10: Laptop won't come out of black screen

Since yesterday my Hp Elitebook 850G3 has had problems Booting up / Logging in and I've gotten a lot of blue screens and today it's been black the whole time with fans going crazy. I can't access the PC, WinRe or login at all. The Blue Screen Codes were the following: Unexpected kernel mode trapKmode exception not handled Irql_gt zero at system serviceRegistry errorBad object headerI'm at a loss of what to do, especially since I can't even access any repair tools and the screen stays black.

Hp laptop screen won’t display except occasionally

I would like to note that step 20 comes up with no files. Perhaps this could be the source of the issues?

 

Laptop went black and won;t reboot

Hi Andree,

Hardware and software conflict is one of the possible reasons why you're experiencing black screen. Sometimes, it is also because of hardware failure. To get this issue fixed, we suggest that you
boot into Safe Mode by following these steps:

• Turn off your computer 3 times while booting. Windows should automatically boot to the Recovery Environment after 3 unsuccessful attempts in a row.
  
• Once you are within the Recovery Environment, select Troubleshoot, and then
  Advanced options, then Startup Settings, and
  Restart. When it restarts, you should see a number of options. Press 5 or F5 for
  Safe Mode with Networking.

Once your computer is in Safe Mode, please follow the workaround provided on this
link. Simply select the similar case that you're experiencing to show the troubleshooting steps.

Let us know how it works.

 

Toshiba Laptop Black Screen

I have a Toshiba Laptop, Was reinstalling windows 7 on it last night left it doing the updates then shut it down. Turned it on this this afternoon only to find the laptop screen is Black and also there is a burning smell coming from the Fan.

I connected the Laptop to a external monitor that is fine, Can go into bios, Windows boots up fine Etc.
Just took apart the laptop earlier to check all the cables where in correctly, Checked the motherboard over for any damage, burnt bits but but found nothing. Just put it back together now but im still getting this burning smell and i still cant use the laptop screen only a external screen.

I Tried Pressing FN+F5 to switch to the laptop screen, But still black screen. Any Suggestions please ?

Thanks
