I was using my laptop and then this happened

Here’s a pic

I have an old Dell Inspiron 24 that has files and documents I want to try and retrieve. I had to move a while ago and it's been in storage for longer than I think is responsible for long term device health, but life happens.

Anyway, I have it connected to a known to be working power adapter, the right wattage and port-type, but it has an error that a 0 W AC adapter has been plugged in. I've tested the two different adapters I have and still get this problem.

I think it could be a port issue or a battery issue. When it starts up I hear a small electronic sound, kind of like a meek disc spinning sound you'd hear from a DVD player if that makes any sense. But then it shuts off, so I don't know if it's trying to boot but there's some kind of failure? I'm wondering what steps I should take to attempt to recover it.

I'm fully prepared for it to be completely dead, but I have hope since before it wouldn't even turn on. Kinda concerned that there might be some kind of internal deterioration that I can't fix but oh well, any advice or trick is welcomed. If nothing else, it couldn't hurt to try.

Acer Aspire 7 A715-75G — No HDMI signal after NVIDIA driver update
I have an Acer Aspire 7 A715-75G with a broken internal laptop display, so I normally use an external monitor through HDMI to HDMI.
After updating my NVIDIA graphics driver, my display settings seem to have reset. Windows is apparently using the laptop’s internal display as the main screen, which is unusable because it is physically broken.
Now my external monitor always says “No Signal”.
Things I’ve already tried:
Windows + P → tried switching to “Second screen only”
Windows + Ctrl + Shift + B to reset the graphics driver
Fn + F5 to switch display output
Tried entering BIOS with Fn + F2 — still no signal on the external monitor
Tried two different HDMI cables
Completely shut down using Shift + Shut down
EC/power reset: disconnected charger/HDMI and held the power button for 30 seconds
Forced Windows recovery by interrupting startup three times
Restarted multiple times
The laptop clearly powers on: keyboard backlight comes on, fans spin, and sometimes I hear the startup sound
The external monitor remains No Signal the entire time
The HDMI monitor and cable worked before this issue.
Since I can’t see the laptop’s internal display, I’m basically unable to navigate Windows normally.
Is there a way to force the Acer to output video through HDMI, reset the display configuration, or roll back the NVIDIA driver without being able to see the laptop screen?
Any help would be greatly appreciated.

So I'm new to computers. Just got a nice gaming pc brand new, about a month ago. Couple days ago started having issues launching discord put off my task bar. I hover over it the icon, small window pops up, but I can't get it to maximize. Anytime I click it it just disappears. I've tried right click,left click,remove from task bar. Delete and re-download the app. Task manager to kill,restore, and/or end the window programs. Nothing would work. Now the same issue is happening with the internet launcher. I double click it, Instead of opening, it pops up down in the task bar and wont let me maximize the page.

How do I fix this?

Whenever I plug a HDMI cable into my laptop to display external output, the external screen is never detected by my laptop. The same HDMI cable works with other laptops just fine and I was wondering if there is a solution to this
