A virus wouldnt do that. it is prolly the screen itself, the backlight or the inverter. if you can hold a flashlight up to the screen and see a faint image, then it is probably the inverter.

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.

My screen keep going white


To me this is a hardware problem.

Let's diagnose, and see Shunka_Reid.
Connect a VGA monitor to the laptop.

A) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.

Number 3 - External VGA display port

General example of VGA connector (port), and VGA cable,

http://en.wikipedia.org/wiki/VGA_Connector

Scroll down a little for the VGA cable example.

You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.

IF not;
There are at least 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor.
3) External VGA monitor ONLY.

Press, and hold the Fn key down, and at the SAME time tap once on the F4 key.
The F4 key is the Display Toggle-Over key.

Still no?
Hold the Fn key down again, and tap on the F4 key once more.

Do you get a good display on the external VGA monitor?
Post back in a Comment.

Also, has the laptop ever been cleaned on the Inside, to your knowledge?

My samsung q320 will not detect my projector


Connecting an External Monitor or Data Projector
You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

My screen on my laptop is broken. Can i plug a monitor into my laptop?


1) connect your external monitor to the laptop and then switch the monitor on
2) boot up the laptop
3) after it has successfully booted, you need to identify which function key toggles the external monitor on/off
4) you should be able to do this by holding down the Fn key and trying each of the F keys in turn, waiting a few seconds after pressing each one
5) begin by holding down "Fn" + "F3", "Fn" + "F4", "Fn" + "F5" etc.

If this doesn't work, it may be worth examining all the keys and look for a small monitor symbol on one of the keys. If you find this symbol, hold down the Fn key and then hit the corresponding key with the monitor symbol.

I have held down Fn and F4 to restore my image to my lap top screen- many times, but the screen remains blank


If you have diverted the screen output to an external monitor or a TV, turn off the computer then disconnect the TV or monitor and turn computer back on again. The computer LCD is the default screen.

Blank screen,pwr sup appears to ok, fans runs, pwr light on


The issue seems to be due to defective video card on the notebook. Connect and external monitor to the PC and check if it works fine or not. You can follow the steps listed below to connect an external monitor.

1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear/side of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook. In either cases, the notebook requires a detailed onsite diagnosis by a service technician.

If your PC is under warranty, contact HP to get available options to get the notebook repaired under warranty.

How can I


Normally a laptop has an external video output in the form of S-Video, VGA, or HDMI. Once you have connected the laptop to the television through one of the available outputs. You will have to enable the external video out on the laptop. Normally this is done by pressing the FN and a labeled F key. Example: If the laptop was a HP you would press FN + F4 to enable the external monitor. Gateway, eMachines = FN + F4. Dell FN + F8. You will have to look at your keyboard close and look for what looks like a little monitor. That key + FN will most likely be how you enable the external monitor.

Once connected, you use the FN + F4(from example) to cycle through the video modes. The video modes are usually Laptop LCD and external monitor, external monitor only, Laptop LCD only,

If you would like to extend your desktop to the external monitor instead of clone the desktop than you will have to go into your display properties and click on the second monitor and check the box that states "extend the desktop onto this monitor". This will allow you to drag windows from the laptop LCD to the external monitor.
