It sounds like the screen inverter is going out. The inverter works in this way: The power supply cuts the amount of power going into the board down, however the screen needs more power to enable it to function properly, so the inverter boosts the power back up to a level that the screen needs. If the inverter starts to go out it can create a multiple amount of indications that are noticable on the screen, one of them is darkening of the screen. It could also be the screen itself, but I'm leaning towards the inverter.

Dark screen


Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.


Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

What's your problem?the screen turns very dim to where you can barely see the picture


Your monitor is going bad or your video card is going bad. Try using another monitor on the computer to isolate the problem. Borrow a monitor from a neighbor, friend, relative or co-worker and see if you can barely see the icons and desktop on it. If the borrowed monitor is bright and clear and you can see things ok, then your original monitor is going bad. If the borrowed monitor shows the same problem of barely being able to see things, then your video card in the computer is bad.

All typeset and pictures have shadows/blur have changed out video card on Lenovo computer - seemed successful for a while but now back to square one. any ideas


Try a different "data" cable between the monitor and the computer.

Connect the monitor to a different desktop/laptop.
If the "shadowing" is still visible, then it's the monitor that has gone "bad'.

Connect a different monitor to your Lenovo computer.
If the "shadowing" is still visible, then your monitor is OK, and your video-card is the problem.

Try to connect your computer to another monitor and reinstall your graphics card. In parallel, try to connect your monitor to another computer and check if it is working properly.
You'll know for sure who the culprit is.

Hp laptop is has docking station connected to acer monitor. The acer monitor has the desktop background but does not show desktop icons. How do I get the icons to show on acer monitor


you will probably find that you have set the screens to run side by side, do a check by clicking the identify monitors, icons will be normaly on the left screen, check the dispay settings and you probably want to set the monitors so they both are showing the same screen at the same time.
good luck.

Assuming you are connecting the mointor to DVI or VGA cable. You can connect the monitor through windows. In vista, right click, personalize, display settings, You should see a greyed out monitor. Click extened the desktop onto this monitor, It should automaticaly detect itself.
In xp its similar. Right click on desktop, go to properties. You should see a screen pop up. Go to the last tab. it should be monitor. Click on teh greyed out area and click Extend the display to this monitor.

Don't know what to do !


connect external monitor to see if adapter is ok. If external monitor comes on OK,(check to see if the FN+F5 or another key has to be toggled for external display) then shine flashlight on screen to see if Icons are visible. If the Icons are visible LCD inverter would have to be replaced. If external monitor works and Icons are not visible lcd is probably no good, If external monitor does not work then Video adapter is bad.
