Hi,

I have an HP Envy 4 Notebook PC with model 4-1080ee

It was working fine last night but when I woke and turned it on this morning, suddenly it's showing a very dim screen. It's still working okay in the background and if I look closely, I can still see everything and I was still able to print the DxDiag. I already tried adjusting screen brightness and contrast but it doesn't work. I tried turning it off then on again, but it still gives me a dim screen.
Can anyone help me on this please? Thank you so much

A quick triage and practical steps to narrow this down without repeating the full specs already posted by . As suggested, start with an external display test, then move from easy software checks to simple hardware checks so you can tell whether this is a driver/power problem or a backlight/hardware failure.

  • Plug an external monitor or TV (HDMI/VGA). On Windows use Windows+P to Duplicate or Extend. If the external image is perfectly bright while the laptop panel remains dim, that points to the laptop panel/cable/backlight rather than the GPU or Windows.
  • Reboot and watch the screen before Windows starts (BIOS/POST). If it is dim even in BIOS, that is a strong sign of hardware (backlight, LED driver, or cable). If BIOS is normal and Windows is dim only after boot, focus on drivers/power settings.
  • Flashlight test: in a dark room shine a bright torch across the panel at an angle. If you can clearly read the desktop when shining light, the LCD is showing the image but the backlight is not lighting properly.
  • Quick software checks (do these first): disable adaptive brightness in Power Options; open the GPU control panel and look for any power-saving/display-dimming features and disable them; try Safe Mode or boot from a Linux live-USB to rule out Windows drivers; uninstall and reinstall the display driver or roll back a recent update.
  • Simple hardware checks (if software checks fail): do a power reset (remove battery and AC for 60 seconds if possible), then try again. If comfortable and out of warranty, reseat the display cable behind the bezel/hinge (loose cable causes intermittent backlight issues). Otherwise, a failing backlight/driver or panel replacement is likely and is best handled by a repair shop or HP if under warranty.

Follow the list in that order: external monitor -> BIOS check -> flashlight test -> software fixes -> power reset -> hardware inspection/repair. If the laptop is under warranty, contact HP before opening it.

If you have a monitor to hand or can borrow one, the first step is to see how it goes from the external output.
