Does it matter if the computer is plugged in or on battery? If its the same either way, yes most likely its either the inverter or "backlight". A good way to test is , plug it in the and external monitor and see how the picture is.

How do i rotate my computer screen


Grab the laptop, and roll it over on it's side

OH, I'M JUST KIDDING!

Hold the CTRL key, and ALT key down at the same time.
Tap on the Up Arrow key until the screen is where you want it.

Got gateway w340ua laptod with a dark screen i already change the lcd and the inverter and still is dark... any sugestion...also i can used with a external monitor no problem


The LCD connector cables are probably not plugged in properly. Since it works with an external display it cant be anything else. The connectors are inside the cable. If you are sure that the connectors are fine then you will probably have to replace the LCD inverter board. Hope that helps, Sai.

Gateway laptop- screen went dark but is still on.


You most likely have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

MY GATEWAY LAPTOP SCREEN WENT BLACK AFTER 20 MIN OR MORE


I'm betting that you need a new "Inverter" board, especially if it's a Gateway 450ROG.
There is an inverter that Gateway used in several models that has a known defect.
Inverters are relatively inexpensive ,and easy to replace. You could ven do it yourself if you have a little skill at disassembly / re-assembly. Tell me the model number of your laptop and I can help you more

My Gateway mx7118 lcd flickers whenever screen is opened,closed,


Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a dim image or flicking image on the laptop's LCD screen it means you have a backlight problem.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Compaq laptop with dark screen


It is possible that the problem is in the video card - that it's just not turning on the backlight. But it's so much more common for it to be the backlight or inverter that I'd try to get a second opinion.
