Hello and welcome to justanswer, My name is ***** ***** i will be assisting you today,
I'm sorry about the issue, Please Turn off the laptop, and disconnect the battery and AC adapter from it. Wait five minutes, then press and hold the power button for 60 seconds and release it. Proceed to connect the ac adapter
without the battery and turn it back on. If still no display, disconnect the AC adapter, reinsert the battery, then reconnect the AC adapter and try now.
Let me know if it works
Take your time please.
what is the model/brand of your laptop ?
It will be little difficult to take off the battery, please try another solution :
press Ctrl+Alt+Del and see if it brings up the Task Manager. If it does, Click on File > Run new task. Type explorer.exe and hit Enter. If this does not work for you, remove all external devices and reboot. If you are able to get display, it might mean that one of the external hardware is causing the problem. If that is the case, start plugging in external devices one by one until you lose display.
If removing external devices does not fix the issue, go to the safe mode.you will have to reboot your computer. At the lock screen, click on the power icon towards bottom left of the display. While holding down SHIFT, click on RESTART. This will make your computer reboot. After the reboot, you are given a number of options – select Safe mode with Networking mode. You can simply press F5 on the screen to enter safe mode. click on Troubleshoot and then on Advanced. Then click on Startup Settings and then Restart. The option to enter Safe Mode will be presented when the computer reboots.
Open Device Manager and Remove the Display Driver
This should fix the issue of black screen for you.
Let me know the results
Has everything worked out please?
