I was on my laptop today and the plug came undone. no big deal, I plugged it back in and fired it up. The screen, however, was barely readable. Very dark but there was a picture in there. Any ideas how to fix this or what it means? is the monitor just burned out? or did I bump something I shouldn't have. Let me know. Thanks.

The symptom you described — a visible but very dim image that later went fully black — most commonly means the LCD assembly, not the video card, failed. already confirmed an external monitor works, so the GPU is probably fine. Suggestions about brightness and power settings from and are reasonable first checks, and ’s battery-reset anecdote is useful diagnostically, but a faint image points to hardware in the screen chain.

Quick, noninvasive checks that narrow the fault:

  • Shine a bright flashlight across the screen in a dark room. If the desktop is visible faintly, the backlight (CCFL tube or LED strips) or its inverter/power feed has failed.
  • Use a phone or digital camera pointed at the screen; cameras often reveal the image when the eye cannot.
  • Open and close the lid slowly to see if the image flickers — intermittent flicker implicates the hinge/LVDS flex cable.
  • Listen for a soft high-pitched inverter buzz (older CCFL systems). No buzz plus a faint image again points to missing backlight power.

Likely causes and practical next steps:

  • Inverter board failure (older CCFL systems): inexpensive to replace; check connectors and caps for damage.
  • Backlight lamp or LED strip failure: lamp replacement or full panel swap may be needed.
  • LVDS/flex cable or connector damage near the hinge: inexpensive if only the cable is bad.
  • Full panel failure: replaces the entire display.

To identify the correct replacement part, remove the bezel to read the panel sticker (part number) and source a matching inverter or panel. Be careful: CCFL inverters carry high voltage — disconnect power and avoid probing unless experienced. If unsure, a local repair shop can diagnose and quote parts vs replacement cost.

I think that when you bumpped it something probably got reset, I think, so that's why its so dark and everything. If you open the monitors menu by pushing a button on the monitor you should probably be able to adjust the monitor brightness and contrast, or if your graphics card broke and somehow ejected the monitor? Dunno.

What model laptop are you using?

This is often a customizeable setting. I, for one, have it, for energy management.

Look under Right Click> Properties > Screen Saver > Power

It has since gone from a little dark to completely black. So i'm not sure what to think. I hooked up my desktop monitor to it and it works fine, i'm on it right now. So the graphics card is working fine apparently. I'm going to assumed it just burned out. It's fairly old. I've had it over 2 years and I got it used and have used it quite often.. it was my only computer for about a year.

I had this problem and was given the advice to take off the power line, remove the battery then try to start the laptop. Quite obviusly it didn't start. However when the battery was put back in and the power in the screen returned to normal. I cannot explain why only that it worked! It went through a few checking processes and I am now fully illuminated once more. Good luck
