Your laptop is probably working with an external display.
Try to change the setting, by pressing the function key (usually on the bottom left of your keyboard) and the Fx key with a monitor (I don't know exactly which key it is but usually is F4 / F5 or F6).

Cq50-215nr screen not working


Hook a spare monitor to the video output usually on the back, if picture okay, the inverter board just below the LCD is the most likely cause, or the backlight behind the display is gone. However if both show the same symptom it is the video graphics card.

If you say this is a new computer, that means all the drivers are installed properly. However, it would not hurt to check. Press on the Windows key + R, then type devmgmt.msc. Click on ok. The device manager will appear. Check if there are unusual marking on the drivers like exclamation point or a red x. If there is, you need to install the drivers for that particular device.
If everything is ok in the device manager, you either need to find the web cam manager application for your portable or download it. Here is a link that will allow you to download and install the HP Web Cam manager 4.8.

Compaq Presario CQ50 Comes on but the screen is very dark!


The Presario's have an intensity control for the screen.

Mine is holding the function button (Fn) down an pressing F8 for brighter, F7 for dimmer.

The marking on my F7and F8 show an asterisk indicating "sun" for intensity.

No sound. problem with audio device on high definition audio bus


You can download drivers from the compaq support site.
An alternate solution is to use a driver update program to find and install missing or outdated device drivers.
