Re: Screen display very dim
Your laptop - are you running it plugged in or on batteries? Many times laptops have power configurations set for the display of the screen (brightness levels) to help with the power usage while running on batteries.
A video signal from the motherboard goes to the LCD screen through the video cable. The video cable connects to the motherboard (or video card) through the connector 1. The video cable connects to the LCD screen through the connector 2. The video cable (in most cases) is also responsible for supplying a necessary voltage for the FL inverter board. The video cable connects to the FL inverter board at the point 3.

look khal sometimes most netbooks have a "hotkey" sequence to dim or brighten the screen on mine its Fn/F4 or Fn/F3 try this first or goto you manufacturers site and find the exact sequence of "Hotkeys" [remember Fn/F5 toggles between screen and monitor]!!
Right click on your desktop and click screen resolution. Increase your resolution. If you are not able to then you need to download your display driver. Search for device manager and go down to your display. If it has a broken or missing driver then go to hps website download and install the driver.
Connected a monitor to the laptop to see if the video card is faulty. If an external monitor works, it is the display's backlight or inverter board.
If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.
Go to the point where you have a stable picture even if it is huge. Right click on an empty space on the desktop and scroll down to properties. Click on settings and increase the resolution a little at a time hitting apply and checking the display as you go. Keep hitting ok to the display settings if you like them. Find the resolution and display size that suites you.
When you start the system, press F8 and then select "Last known good configuration". If it does not work the first time, try at least three or four times.
You can try installing the OS again but you will lose the data in your c drive.
Check with the BIOS configuration, Take a note of the original configuration before you make any changes.
sounds like the backlight has gone....test with an external monitor....if the external monitor works without any problems...the backlight has gone...better to get a professional to do this as its kind of fiddly and involves taking the screen apart
So, if your motherboard is turning on and the fan comes on than for now you can check to see if your back light turns on for your lcd panel by going to a dark place and turn ont he laptop there. Than check if you see a faint light that stays on or a flicker. If you see a faint light or the display is dim than it is the inverter on the lcd panel otherwise you may need to replace the video card which can be integrated onto the motherboard and may require a new motherboard. All depends on the model you have.
