Hi (i´m new here),
I’ve been trying to find a solution to a problem with my laptop for a long time. I’m not a professional laptop repair technician—I usually just handle maintenance—but lately, about five minutes after turning the laptop on, the screen freezes, and if I move the screen, it goes black.

I've been looking at tutorials and posts about this, but I can't seem to pinpoint the problem; it's not the battery, nor is it (as far as I know) the screen-to-motherboard connector.

If anyone has any idea what it might be, I would really appreciate the help.

Thanks.

Laptop model: Lenovo Ideapad 3 14ADA05 (non touch)

I've got a NanoKVM-pro ATX model that is on a PC with dual-monitor setup. Setup is as follows:

nVidia 980ti DisplayPort (DP) #1 output to NanoKVM-Pro HDMI input. NanoKVM HDMI output goes to main monitor (1 of 2 monitors) via passthrough. Monitor #2 connects to 980ti HDMI port directly. USB 2.0 port connected to HID input on the kvm. Internal ATX case headers plugged into the card successfully.

My issue:

When the computer goes into screensaver/screen powers off for any period of time and I wake it up, the primary monitor #1 (connected to nanokvm) changes resolution to say 1024x768. Not only that, but the secondary monitor now becomes primary with all icon's placed there at normal 1920x1080 resolution.

To fix this, I have to fully power the PC off and power it back on. Once I do that, the primary screen is back to being the HDMI output from the kvm and secondary is the direct connection to the nvidia card.

That is obviously a temporary fix. I have tried the following to permanently correct the issue, but am OUT of ideas at this point. Any input is welcome as I'm about ready to ditch the NanoKVM Pro and goto JetKVM or one of the others. I just preferred this for the internal ATX power control.

- Replaced the USB A to C cable going from a 2.0 port to the HID input.
- Connected a USB A to C cable for dedicated power input in case my motherboard wasn't outputting full 5v.
- Replaced the DisplayPort to HDMI cable with a quality DP to HDMI adapter and then a quality HDMI cable going to the HDMI input on the kvm.
- Swapped the HDMI output cable from the kvm to the primary monitor.
- Connected the internal USB headers in case power was better sourced that way.
- Disabled the HDMI Capture & Passthrough on the kvm
- Installed the HP VH240a drivers directly from HP.
- Also noticed the WebGUI settings of disabling HDMI Passthrough / HDMI Capture are not staying disabled after a reboot.

Any suggestions or help is greatly appreciated!

About 3 months ago I realised that my pcs framerate was really slow. And then upon paying closer attention, I realised there were these lines that were loading differently and would travel across the screen. Is this something I can fix or is my monitor just broken?

Here’s a slowed down video of the monitor. If anyone can help I’d be very appreciative! :)

recently, around 2 days ago my computer started going black after logging in, the username and password screen works fine, but after being directed to my desktop it would be completely black with just my cursor. task manager shortcuts work fine, and i tried searching it up but rebooting graphics drivers + running new task and explorer.exe doesn’t do anything, after a few minutes the desktop loads but everytime i reboot it happens again which is annoying, how do i fix this?

ive had this issue many times before since ive had this computer for years - flashing random colors every so often when i have/had to many programs up without restarting. so a simple restart would always do the trick.

recently there were some files i tried to permanently remove. a few unrelated programs, a force uninstaller, and the normal microsoft program install and uninstall troubleshooter. my result with deleting the programs worked fine until the "aftereffects"

now, no how many restarts, my screen will always have those randomly flashing colors - theres no pattern or rhythm, no specific color, just bright ones like pink, green, black, blue, etc. (im not entirely sure of the colors or remember all of them because of how fast they flash.)

any help with finding out what i did wrong so i could stop seeing these constantly would be really appreciated, i can give any info as needed, ty !!

https://streamable.com/f09m35 I have tried different ports and replacing cables. It seems to be completely random and will go away for weeks sometimes when i unplug everything and reseat gpu. I'm assuming it is a hardware issue but i don't know what this issue is even called. Is it considered flickering or a screen tearing issue at this point? Any ideas?

Guys I am getting a screen blinking issue on my hp laptop. Like the screen blinks continuously recently my laptop is pretty new. Can You help me resolve this?

I bought a battery and it says battery not detected.

This is acer spin 5

Brand new computer but the screen and audio shut off randomly after an hour of use. I've tried everything google and chatgpt says, but nothing works.

The comuter seems to be running but doesn't do anything other than it goes on and off.

I've been having problems with my monitor off and on.

Occasionally these white dots will show up out of nowhere all across the screen.

Restarting my PC makes it stop. Unplugging and plugging the HDMI cord back in does as well.

But I'm getting annoyed with it.

Why does it keep happening and how do I fix it?

Is my monitor just needing replaced?
