another important thing to mention is how when I unplug the power cord it makes 1 short beep also happens when I re-plug it, the fans seem to be in idle.

    When your laptop shows no display but the backlight is on, it suggests a problem with the display itself or the connection between the laptop and the screen, rather than a complete failure of the laptop's power.
    Here's a breakdown of potential causes and troubleshooting steps:
    Possible Causes:
    Loose or Damaged Screen Cable:
    The cable connecting the laptop's motherboard to the display might be loose, damaged, or disconnected.
    Faulty LCD Panel:
    The LCD panel itself could be failing or damaged.
    Driver Issues:
    Outdated, corrupted, or incompatible graphics drivers can cause display problems.
    Graphics Card Problems:
    If the laptop uses a dedicated graphics card, it could be failing or overheating.
    BIOS Issues:
    Incorrect BIOS settings can sometimes prevent the display from working properly.
    Backlight Issues:
    The backlight could be working independently of the display itself, causing the screen to be dark but still lit.
    Troubleshooting Steps:

    1. Check External Monitor:
      Connect an external monitor to your laptop to see if the display works on that screen. If it does, the problem is likely with the laptop's screen itself.
    2. Re-seat the Screen Cable:
      If you're comfortable with basic laptop disassembly, carefully open the laptop and check if the screen cable is properly connected to the motherboard and the LCD panel.
    3. Update or Reinstall Graphics Drivers:
      Go to Device Manager (search for "Device Manager" in the Windows search bar), find your graphics adapter, and update or reinstall the drivers.
    4. Check for BIOS Updates:
      Consult your laptop manufacturer's website for BIOS updates and install them if available.
    5. Run a System Restore:
      If the problem started recently, you can try restoring your system to a previous point in time.
    6. Contact Support:
      If you've tried these steps and the problem persists, contact your laptop manufacturer's support or a qualified technician.

    Press the power button for 15 seconds and turn on your laptop again, if that doesn't work press the powerbutton until you see the keyboard light up again.

    If it still doesn't work try again but this time 10 seconds. Rinse and repeat until it turns on.

    If you are still using Linux, try the below mentioned steps to undegrading the kernal.

    There should be an nvidia-prime-applet in your panel in the lower right. Considering your inxi output, it should be an Intel icon because you are currently running in Intel Powersave mode. Click the applet to see the options. Switch to On-Demand mode and then reboot your computer to fully complete the switch to On-Demand mode.
    With a 10th-gen Intel cpu, your system will run better with a newer kernel. There is both a 5.11 and 5.13 available in Update Manager.

    Instructions for upgrading:
    Open Update Manager. Select View > Linux Kernels and click Continue. Select either 5.11 or 5.13 on the left panel and then click the top-most option on the right panel. An "Install" button will appear. Install the kernel and then reboot for it to become active.

    I hope this helps! If this was useful, please hit 'Yes' or 'Like'! Thanks! 😊
