Having problems with your HP PC Desktops ?

HP Pavillion dv9500t lcd screen is extremly dark. I can barely see anything once it is booted up. I can hook up an external monitor and the laptop functions properly with exception of the laptop screen. I have gone through all of the hp recommendations to check. Is their a backlight lamp or something that I can replace? Iam not familiar with the new ultra bright screens.

From the Windows desktop, hold the fn key and press the f7 key c00776226.jpg to increase or the f8 key c00776225.jpg to decrease the brightness of the display.
