    Hi,

    I encountered another problem from my HP laptop and this time it is dark screen. As soon as I turn my laptop on within 2 seconds my screen goes very dark, however it is still performing its normal functions but with only 5% brightness which is very dark for naked eyes,. but when I try to connect it thru my TV it all work fine. Also if I close the lid and open at once my laptop screen became normal but soon goes dark in 2 seconds. I don't think the problem is backlight coz it seems normal for 2 seconds every time i close the lid and reopen it. please help!

    Sorry for the heading: HP Laptop screen goes very dark

    It sounds like it could be the inverter. The inverter is a small board, usually in the lower part of the screen. Its job is to convert the DC voltage to a much higher voltage needed by the fluorescent bulb in the LCD.

    It is easy to access once you have the bezel off of the screen, and can be purchased for anywhere from $20(US) to $45(US) on average.

    Thanks Pedro,

    Is there any way by which I can fix this by myself?

    It's a pretty easy task on most laptops. Usually the only tool you'll need is a very small philips screwdriver and a plastic knife or guitar pick to pry the bezel once you get the screws out.

    There are pictorial how-to's all over the web.
