Laptop comes on but screen is black/blank


If you don't see anything at all and it has not been dropped or banged it maybe something as simple as the Video out selection. Look at the keyboard and locate the [FN] and the [F4](Actually look for the key with a small video screen on it which is usually the F4 on HP machines). After turning the computer on press and hold the [FN] key then press the [F4] Key. There are 3 modes programmed into the video selection. Computer monitor, Computer monitor and External Display and External Display only. What happens a lot of the time is someone may have accidentally pressed this combination of keys and the video is actually redirected to the external monitor only option. If this does not help and you can connect the computer to an external monitor and use that key combination to get the output to that screen then the problem is most likely the Back light for the monitor of the screen itself. Both can be replaced. HP can provide the back light part at a reasonable price. For the screen itself I recommend you go to someplace like E-Bay and purchase the replacement. Make sure you look at the sellers past record so you don't get taken. I DO NOT recommend using Craig's List for anything.

I have an hp ze2000. I hooked it up to an external monitor. When I unhooked it and restarted it my laptop screen now stays blank. Who knows the answer to this?


I think you have to reset through setup F12 or is it F8 restart and push one or the other, then locate menu for screen click to enable.

Haven't come across this before. Best I can suggest?

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.

Which function key allows to switch to tv


Hi there,
You need to press hold the FN key and press the F4 function key once which toggles the display to the External Display source like the television connected along with the LCD of the Notebook.
If the FN and F4 key combination is pressed again, the display will dissappear from the LCD of the Notebook and remain only on the external source.
If the FN and F4 key combination is pressed third time, the display will be back on the LCD of the Notebook and will not remain on the External display source.
Here are these details in other way :
First time pressing FN + F4    ---> Display on LCD and External display
Second time pressing FN + F4 ---> Display not on LCD but on the External Display
Third time pressing FN + F4 ---> Display back on the LCD and not available on External Display (Normal position).
Below are the details of what the Function keys in your DV1000 Notebook work :
fn + f1 Opens Help and Support Center fn + f2 Opens print options window fn + f3 Opens default Internet browser fn + f4 Switches the image among displays fn + f5 Initiates Standby fn + f6 Initiates QuickLock fn + f7 Decreases screen brightness fn + f8 Increases screen brightness fn + f9 Plays, pauses, or resumes an audio CD or DVD fn + f10 Stops an audio CD or DVD fn + f11 Plays the previous track or chapter on an audio CD or DVD fn + f12 Plays the next track or chapter on an audio CD or DVD fn + esc Displays system information.* (*To clear the system information display, press esc.)
Hope this helps...

Video projector from a laptop


You can connect the Projector to the VGA Port of the Notebook which is a Blue Port which can be seen at the rear of any desktop computer to which we usually connect the Monitor to.

The VGA Port will have 15 holes on it and should be in Blue colour.

You can locate the VGA Port at the Left side of the Notebook.

Locate the port according to the information available below :

http://h10032.www1.hp.com/ctg/Manual/c00726464.pdf

Refer to page number 14 (18 of 32) in the manual.

Once you connect the Projector to this port, hold the FN key and press F4 key once.

This wil get the Display on the Projector connected to the Notebook.

If you just want the display only on the Projector, hold the FN key and press the F4 again.

Now, if you want the display back on the LCD of the Notebook, Press the FN + F4 third time.

Hope this helps..

Hooking up projector to my computer


If it's a laptop, you might need to activate the vga output, using the blue "fn" button in combination with f4,f6, f7 or f8, depending on your manufacturer.

On an HP, you press FN+F4 once, to turn off the LCD, and use the projector. Press it again to run both at the same time, and press a third time to use just the LCD. The cycle repeats on each press.
