Only half of my screen on my dell inspirion 9200

Hi Msdco1, 1st try fixing your laptop..... The link below is a YouTube video showing 3 ways on how to fix your laptop, Also there's videos down the right side of the link that may help as well, I hope this helped....CHEERS..
ALL LAPTOPS DISPLAY NOT COMING ON BLACK or BLANK SCREEN DIM DISPLAY

turn on the computer --> press f8 on start up after flashing of the bios screen

it shows advanced start up options from the menu select safe mode

then it shows classic logon screen type username as administrator leave password as empty and press enter

now you can reset the password using user account control panel or using computer management from control panel

Yes! but it is a good idea to hook a spare monitor to the video output first to make sure there is no problem, if okay! replace the LCD screen. Go to www.ebay.com Type: make and model of the laptop and refine search to screen, a list of sellers will pop up showing the prices.

start your laptop and tap on the F8 key when you start up.

this will get you to the "Advanced startup Items" menu

select "do not auto restart" near the bottom of the menu and press enter.

This will allow the blue screen to stay up and you will be able to get the stop error code. You should be able to find a fix for it here:

Sounds like the LCD has been damaged. You could get another LCD for it. Here's a link to Dell:

Turn off vista hybrid sleep and hibernation mode. It causes more problems then it helps.

If the drive is showing an error (or is missing) in device manager, do the following:

Start Registry Editor (Start, Run and type in regedit then click O.K)
Locate the UpperFilters value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
On the Edit menu, click Delete, and then click OK.
Locate the LowerFilters value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
On the Edit menu, click Delete, and then click OK.
Quit Registry Editor.

You can reseat the video cable to the video card, and see if that makes any difference.

Also, Connect an external monitor, then press FN+F8 and see if the issue appears on an external screen, If not, then replace the LCD

Try right clicking on the desktop then selecting "properties". A window should appear. Click the "settings" tab at the top of this window. In the settings screen is a slider bar for screen resolution try sliding this to different places and clicking the apply button at the bottom of the screen until it is right. If this does not work go to start then control panel. If control panel is not in classic view switch it to classic view by clicking "Switch to classic" in the left hand column. Next click the icon that says "system" below it. In the window that opens click the tab that says "Hardware" in the hardware window click the "Device Manager" Button. A new window will open that has a list of things. There should be an entry in the list called "display adapters". Click the plus sign beside this. It should then expand and have a subentry for your display adapter. Right click on this sub entry. A popup menu will appear in the menu click "uninstall". A warning message will appear saying you are about to uninstall it. Click "OK". Now close all your open programs and restart your computer. When your computer restarts it should detect your screen as new hardware and configure it properly.
P.S. all directions are for Windows XP. Please rate me! Thanks.
