Black Screen right after loginon on IQ815

[ScouterAtEnd]

I allowed a Windows update a few days ago and now the screen goes black right after I log in. The only other recent change was installing the app and drivers for an HP multi function printer/scanner. The scanner part still didn't work, so I went with a generic one from the Microsoft Store. Obviously it was working when I did all that.

I've gotten to Safe Boot and tried System Restore but the only restore point was hours old, not before last week

Uninstall Updates would not complete running fully, and accomplished nothing.

CTRL-ALT-DEL will bring up the task Manager window, and if I hit the power button, the screen for 'Shutting down...' appears briefly.

I've saved all the files I want thru Command Prompt, and the screen worked fine thru all that, and will stay on for Safe Boot too.  So this has to seem to be a software issue rather than hardware.

I'm inches away from 'Reset this PC' but I see this was an issue years ago. I'm wondering if anybody else experienced the same issue with the latest windows update, or has an up-to-date solution.

She's an oldy for sure, but I love my all-in-one, huge touchscreen and want to save her. Please HELP!

I can get to the CTRL-ALT-DEL task screen, but after selecting Task Manager, the screen goes black again, so I can't choose any processes to shut down.

I'm running Windows 10 BTW

Hi@ScouterAtEnd, Welcome to the HP Support Community!

I recommend you follow the below steps and check if it helps.

1. Turn off your HP laptop.
2. Disconnect all external devices (printers, USB drives, etc.) from your computer.
3. Remove all recently added internal hardware.
4. Press the Power button to switch your HP laptop on.
5. Once your unit starts booting, immediately press the F11 key. Repeatedly press it until you see the Choose an Option screen.
6. Select Troubleshoot.
7. Choose Reset this PC.
8. You can either opt to keep your files or to remove everything.
9. Select Keep My Files when you want to retain your data. Once you click Reset, your operating system will be reinstalled. The process may take a while.
10. Choose Remove Everything when you want to remove all your personal files.
11. You can opt to remove everything solely on the drive where your operating system is installed. On the other hand, you can click All Drives when you do not want to retain any data.
12. You can also fully clean the drive you selected or just remove your files.
13. Click Reset.

Hope this helps! Keep me posted.

I've always been afraid this would come down to restoring the system.😖 I'm in the middle of that now. We'll see . . .

My next concern though is how this happened. It seemed that it started when a Windows update got pushed. I am going to turn off automatic updates. I will always set a system restore point when there is an update (since Windows wasn't smart enough to do that on its own!). I can backup more often too I guess.

What else can I do to protect against Windows?!?!?!?

@ScouterAtEnd,

We have done the basic troubleshooting as per the document and the notebook needs to checked taking remote access so that get to know it's a hardware or software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile Name, you should see a little blue envelope, please click on it.   

Have a great day!
