Question about Computers & Internet

Look at your function keys there will be one with a pic of a monitor... You have to hold the function key down while pressing the one with the monitor... Sounds like you switched it to external monitor mode by accident

May I ask what model it is?
The dv9000 model if you havent been told had some that had bad motherboards and that sounds like what mine problem was.
If its a dv9000 then you may want to talk to a HP agent about that.

SOURCE: black screen
There are only three issues it could be...
1. The ATI video card has become warped due to overheating which woulod need to be replaced. You can find them used on Ebay for around $65 or new for around $125.
2. The cable has become frayed that connectects the video card to the inverter board due to opening/closing the laptop. Like $7 on Ebay.
3. The ribbon cable connection to the LCD panel itself has started to come undone which is also a common problem. Around $125 on Ebay.
You can try pressing down above the F5 key to see if the screen will come back up.
-Please give me a thumbs up :)

You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.
Defective CCFL backlight, it may have the following symptom:
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

most likely the resolution of your screen is too high for the LCD to handle. Go to desktop settings and go one notch lower and that should do the trick.

SOURCE: screen won't work on HP laptop
This may be caused by the video graphics cards. If you have a warranty, check with HP and they will fix for free as they warranty all hardware for two years.
You can check to make sure it is the video graphics or the screen by running a simple test. Get a monitor and attach the laptop to the monitor. If you see a picture, then the screen (probably backlight) is out. If you do not see anything, then it is definetly your video graphics card. You can order a new screen or VGA card on eBay, which I highly recommend to save money. Get a friend or you can put it in, just make sure you put the laptop back together perfectly and protect from static electricity.
It is easier to get another replacement screen if the backlight is out because these can be hard to replace. The backlight usually cost a couple of dollars but the frustration of trying to replace is like trying to replace a lightbulb in a very tight spot. A screen will run you around 40 dollars. If it's the VGA, then you are looking at 60-90 dollars.
