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?

Most laptops have a "toggle":
* output video only to internal LCD screen,
* output video only to external HDMI port,
* output video to both internal & external.

Set the "toggle" to the best value.

Try hooking up an external monitor. If the external monitor is working and showing you what you are used to seeing, than you just need to switch the laptop back to it's regular display mode.
There is a key that looks like this
'o'
you need to press the function key and this key (usually f4) at the same time to switch displays.

First thing you should try is hooking the laptop up to external monitor. It's usually easier to hook everything up, THEN power on the laptop. Most laptops will detect the external monitor and automatically provide video, some models require pressing FN+F5 Just examine your laptop keyboard carefully for a pair of icons that looks like two monitors.

If you get external video then more than likely the lcd on your laptop will need to be swapped out. If you don't get any video it could be a GPU or memory issue.

let me know what happens and I can guide you along.

you need to change the lcd inverter card of your note book

Hello, I'd start by hooking up another external monitor, that way you can rule out if your video/graphics card is working. If the new monitor works that means your video card is fine and you'll need to look at replacing your current monitor Good luck, mpawlak908

If it still doesn't work when you hook it up to an external monitor, assuming you did that properly, then it is your motherboard/video card.

If you have a seperate video card, I would replace that first. If you don't have a seperate video card, then you need a new motherboard.

FIRST - I would try hooking it back up to an external monitor, and making sure you switch it over to use the external as the default. otherwise you wont get picture.

Sorry... good luck.

Without more information I cannot be sure, but I would say that it could possibly be set to use an external monitor. There is a FN key command to switch between your LCD Screen and an external screen. Try that. If you have an external monitor that you can plug into the VGA connection, that should tell you for sure. Good luck.

Firstly, the LCD+external setting will switch one or the other or both on.

Secondly, if you go into your display properties (or even the advanced page where your video card additional features are) you can usually select which monitor is "primary".

I suspect that your external display is primary, and the LCD screen is not "enabled" or used as part of the desktop.

The settings are all there, it's just a matter of finding them (depending on what video card is in whatever laptop you have)

This might have happened in the first place if you accidentally hit "Fn" and one of the "F" keys up the top. Fn + F6 on my laptop will switch LCD/external monitors on and off. (for example) There is usually a little blue picture on one of the "F" keys to denote that function.

There are a couple of possibilities.

1. A cable has come loose inside the computer.

2. A cable has become defective.

3. The LCD is defective.

If you wiggle the LCD back and forth and you can get the picture to work again intermittently then answers 1 & 2 above would be more likely.

I think your LCD is stuffed is it under warranty do you know BUT if the screen is cracked they wont replace it typical HP. To get your external monitor running hold down the function key and the blue monitor looking key similtaneously normally on compaq its the F4 key but look around your keyboard (looks like a monitor) and is blue letters.
