Problem Using stand alone monitor with laptop computer
I have been using a separate monitor for my laptop because the built in monitor went black. Everything was working fine until this morning. The laptop screen is coming on, but it is dark. I can just barely see my desktop on the screen. The separate monitor says it's in power saving mode or says "input signal out of range". I'm pressing (function - f 9). Any ideas?
Re: Problem Using stand alone monitor with laptop...
It could just be in the power saving mode. if it is its easy to fix. just go to the notebook mobile settings or battery settings and change the screen brightness or mabey you have a screen brightness changer on your keyboard?

First hook a spare monitor to the video output jack usually on the back, if picture comes up! it indicates a bad inverter board, or the backlight has stopped working, if the spare shows the same problem, it means the video graphics card is defective and normally built into the motherboard.
What OS are you using? In WIN XP, right click the desktop and select properties. In the DISPLAY PROPERTIES window, select the SCREEN SAVER tab. Thyen click the POWER button at the lower right. Next select the ADVANCED tab. Look for the pulldown for POWER BUTTONS. Under "When I close the lid to my portable computer: click the pull-down and select DO NOTHING.. Then click OK.
Check to see if you have the machine switched out to a stand alone monitor. This is a feature on many lap tops that lets you re-direct the signal out to a larger monitor, or if your monitor fails you can display the computer info on another screen. This feature is engaged by holding down the Fn key and tapping teither the F4, or F6 key on many lap tops. This feature can be toggled by both displaying at the same time or switched to the stand alone or the Lap top.
The other cause is that the machine has malfunctioned usually because of the CPU failure and there is nothing to boot the machine up.
The problem you are facing is of a power scheme setting which is configured to go blank after a certain time of inactivity - You can change the power scheme option from your control panel power option icon and make it more timing or choose option never - please tell me the exact operating system you are using so that I can tell you what to do ?
Try connecting to a stand alone monitor and use the fn and Video switch key, what ever it is on your lap top to see if it will switch to the stand alone monitor. If it works on the stand alone monitor, the graghic chipset is ok. BUT you may have a problem with a broken wire that runs to the lcd panel. Replacing is Not for the average user to fix. Make sure it isnt your Video Chipset 1st as it is probly soldier to your Motherboard and you would have to buy a replacement motherboard, they average (150 to 450 bucks) not put in.
I'm just "guessing" here, but when the updates are installed, you may have to restart the computer. On a laptop, unless you go into the control panel and designate which monitors are installed, it reverts to the built-in monitor and you have to use the Fn and whichever function key controls the monitor assignment. Yes, there should be a way to permanently tell the machine that the external monitor is the primary one. I think (since I don't run Vista here) that you would get into the control panel and the display settings and designate the attached monitor as the primary. I'd be interested to know if this works. Be sure when you go to the display properties that you right-click on the external monitor and choose "attached". Anyway, give that a try.
Vista does not have a stand-alone feature for Compaq Presario c700 webcam. You need to have another application to use the webcam. Fortunately, I found an application, YouCam, that allows you to take snapshots (and even videos) using the built-in webcam of the laptop.
