Screen on ma2a gateway doesn't turn on. Is it the video card?


Borrow a monitor and plug it into the VGA port. That might tell you whether the graphics card is bad.

How do i switch to external monitor


Virtually all IBM and Lenovo ThinkPad and ThinkCenter laptops allow you to hook up an additional monitor or projector to the computer. When you add an external monitor or projector to your notebook, you can choose to view the display on the computer, on the external device, or on both the laptop and the external monitor or projector at the same time. Toggling between viewing devices is as simple as pressing a couple of keys on the keyboard.

Shut down the laptop. Plug the VGA monitor cable from the external monitor or projector into the blue VGA port on the back of the computer. Turn on the external monitor or projector first, and then the Lenovo laptop. Allow the notebook to boot into Windows normally. Press the "Fn" and "F7" keys at the same time to switch the display from the laptop to the external monitor or projector. Press the "Fn" and "F7" keys again to enable the display on both the laptop and the external display device. Press the "Fn" and "F7" keys again to display screen contents only on the laptop LCD. choose support you need http://www-307.ibm.com/pc/support/site.wss/MIGR-54305.html http://www-307.ibm.com/pc/support/site.wss/MIGR-4YQHUC.html enable tv out on thinkpad http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-58625

Lenovo 3000 n200 0769AMU press power on switch green light on after about 1 sec screen still black no HD light fan running


Welcome to Fixya

Try to drain the electrostatic charge of the motherboard that usually cause this issue. I wrote a tip on how to do the power drain. Try to plug in external monitor on the VGA port and see if you are getting display using external monitor. If you are getting display using external monitor then the problem would be the laptop LCD. If you are getting the same black screen using external monitor then the problem is already the motherboard.

Thank you for using Fixya!

My laptop has a black screen. The lights are on and I can hear the motor and fan.


I'm assuming that when you turned it on, all you got was a black screen (you didn't say anything different).
First, make sure your laptop screen has been chosen as the display screen. On each laptop, there is a Fn and special function key combo that will allow you to switch between the laptop and an external monitor. Press that combination of keys several times.
Next try to boot in safe mode by restarting the computer and pressing F8 until you see the menu.
Next, connect an external monitor to the SVGA port.
If none of these is working for you, your video card has most likely quit on you.

THE SCREEN IS BROKEN ON LAPTOP CAN I CONNECT IT TO MAIN COMPUTER SO I CAN USE SCREEN ON THAT


You may need to press a key combo to switch displays. Many times this is Fn + F7 or Fn + (some F key)
You may have other problems with the system that prevent the display from working.

My Amilo A1630 laptop is not working. The screen will not come up at all. Power switch is turn on and the green light is on. Any ideas what is wrong?


To isolate the problem try this:

Plug your laptop to an external monitor using the monitor out port on the laptop. Hit the "function" key and the corresponding F key that has the LCD Screen/External Monitor icon. Usually around F6-F8 or so.

This will test if there is something wrong with the screen and if the laptop is booting up past the BIOS.

Please comment back with results.

My Hp PAvilion DV9000 LAptops screen keeps going blank. If I hook it up to and external monitor then it works.


YOUR INTERAL DISPLAY ADAPTOR MAY BE GOING BAD, HAVE U TRIED REINSTALLING THE DRIVER , IF SO ITS UR ADAPTOR OR THE SCREEN ITSELF WHICH IS NOT A BIG PROBLEM REPLACING. THE EASIEST THING TO DO IS ASSUME ITS THE MONITOR. DOES IT DO THIS IMMEDIATELY OR DOES IT TAKE A WHILE. WHEN U HOOK UP THE OTHER MONITOR DO BOTH SCREENS WORK.

I have an LG laptop connected to an external monitor. It has worked in the past. In the last week when i turned on my laptop the external motitor showed the boot up process right up until the final...


There should be a button on the keyboard that controls the output...it is done by pressing the Fn key (function) in combination with the Fkey (all those F1..F2..and so on next to the Escape key) Also, you can Right click anywhere on the desktop (the first screen you get when the computer boots to Vista) and when you get the set of menus, choose the bottom one calle "Personalize" This will bring up the "Personalization" screen. Here you can choose the bottom "Display Settings" to make sure you have your second monitor (external) ready under the "extend my desktop onto this monitor" check. Go on and click on the #1 screen and the #2 screen and play with the options so you get a good feel for them and to see wich one works best for you.. Hope this helps.

I have hp pavilion dv6226us and when booted up the screen stays dark. You can see display only if you shine a light onto the screen. I tried to turn up the brightness and did't have any luck.


The VGA card or the VGA driver is not properly installed,perhaps.Try reinstalling the driver.
If you suspect the monitor brightness controls then try fiddling with them untill the brightness is good enough.
Check monitor cable also(VGA).
