How disable internal display vga - Acer Aspire 2100 (91.AB675.D02) PC Desktop

Normally you can switch between internal and external screen by holding the fn-key Down while hitting one of the function keys with a Screen symbol on (f7 or f8)

Press, and hold down on the Fn key, and AT THE SAME time tap once on the F5 key.

The F5 key is the Display Toggle-Over key.

Still no?
There are at least 3 display options;
1) Internal monitor of laptop ONLY.
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down again, and tap once more on the F5 key.

For additional questions please post in a Comment.

A) Post THE Product Number on the bottom of the laptop. It's in the white Service Tag. P/N = Product Number.

B) On the left/bottom side of the LCD screen frame (Display Bezel), there is a switch. Looks like a small button.

This is the Internal Display Switch. (May not be in this exact position for your model. Look around on the Display Bezel, that surrounds the LCD screen)

When the laptop is closed, the switch turns off the display, (Image on screen), with the computer still on.
Tap it a couple of times lightly, with the eraser on the end of a number 2 pencil.

See if anything happens. That switch may be bad.

C) Laptop off, monitor off, connect a VGA monitor to the VGA port on the laptop.

Example of a VGA cable, and VGA connector, (Port),

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

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

C) Turn the monitor on. If a CRT type of monitor 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,

1) Internal monitor of laptop ONLY
2) Internal monitor AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key. At the same time tap once on the Display Toggle-Over key.

Don't know what exact HP laptop you have. For most HP's it is the F2 key, or the F4 key, that is the Display Toggle-Over key.
(Key has an empty rectangle on it, with a vertical line on each side)

Still no display on the external VGA monitor?
Hold the Fn key down again. (Bottom left of Keyboard)
Tap once more on the Display Toggle-Over key

NO display on the external VGA monitor, means you have a bad graphics chipset.

(By using an external VGA monitor, you are bypassing the Internal Display Switch, and the Display Assembly. (Internal monitor of laptop)

If you have a display on the external VGA monitor, you have a problem with;

1) Video Cable, (Display Panel Cable for HP)
or
2) Display Assembly

Post back with your results, and if you have a display on the external VGA monitor, we will go on.

If you do not have a display on the external VGA monitor, you are looking at motherboard replacement.

No display on laptop's internal monitor, and there is no blinking cursor?
Start with seeing if it is a display problem.

Connect a VGA monitor to the laptop. If the display does not show on the external VGA monitor, the problem is the graphics chipset.

You did not state the model number of the Fujitsu laptop, therefore all I can give is generic basic information.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the laptop.
This is an example of a VGA Cable, and a VGA connector,

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

The VGA connector (Port) on your laptop is either on the side, or back of the laptop. May be marked on laptop as RGB.

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

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default the display should show on the external VGA monitor.
If not there are at least 3 display options;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press the Fn key down, and at the same time tap once on the Display Toggle-Over key.

The Display Toggle-Over key is one of the F keys at the top of your keyboard. F1 through F12.
It will have a monitor symbol on it.
(For example most HP laptops use the F4 key )

No display on external VGA monitor? Hold the Fn key down again, and tap once more on the Display Toggle-Over key.

If no display shows on the external VGA monitor you have a bad graphics chipset. Motherboard replacement.

If a display does show on the external VGA monitor, you have a problem with the Video Cable, and/or in the Display Assembly.

Try another monitor, if problem still exists your VGA is damaged, if youre using the onboard vga then connect a PCIex vga card get into bios (suppose the display problem is solved) and disable the onboard VGA option. Keep your pc running like this (using external VGA adaptor).

Disconnect the monitor from the motherboard and shut it down. Open the case, find the battery and remove it for 5 minutes. Put it back, connect the monitor and boot normally.

you cant join two different platform vga cards. simply because they have their own platform and have separate drivers, so they conflict each other thus causing one of them shut off or disable..

Plug in an external vga monitor into the port on the back.. If it works the internal display may be disabled. Usually it involves hitting one of the function keys at the top with possibly shift or control. If the light comes on and there is only one beep when you turn system on tre above . If there is no power light try adapter or battery. If you have beeps most likely the memory is loose or bad . If after making sure internal screen is turned on there is a problem with video card , back light or screen.
Thanks,

in bios settings there is a option enable or disable onboard display card check , one more option is there press F8 key when you are restarting the system some options is come their select enable vga mode

I believe if you install an AGP card the onboard VGA is supposed to be automatically disabled. Did you buy an AGP card?
