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 to increase or the f8 key to decrease the brightness of the display. If using the function keys does not resolve the problem and you have a Lid Actuator on your particular model, check the movement of the Lid Actuator switch to determine that it moves freely and is not stuck.\015\012\015\012\015\012\015\012\015\012\015\012\015\012NOTE: \015\012The key numbers ( f7 or f8 ) may vary depending on the notebook PC; however, the images on the keys should be familiar. \015\012\015\012Check the movement of the Lid Actuator switch\015\012The Lid Actuator switch is available on some models.

If the display does not return to normal brightness when the switch is released, the switch may be sticking and need to be repaired. Contact HP service and support for further assistance. \015\012If the display turns off when the switch is pressed, the power management function may be set to hibernate or turn off when the lid is closed.\015\012\015\012Install updated BIOS and drivers\015\012To resolve certain hardware and software issues, use HP Health Check to automatically search the HP web site for an updated BIOS as well as any updated software and drivers.\015\012To launch HP Health Check, follow the steps below.\015\012\015\012
