Re: How to adjust the brightness on a HP Pavilion dv4000...
Its usually the Fn key (bottom left) and a function key on the top line like F1 to F12 the brightness is the picture of the sun. I couldnt find any specific information on your model but most HP's are the same.

Below are instructions to adjust brightness on HP laptop
Press the "Fn" key with the computer turned on and hold the key.
Press the "F7" or "F8" key on some HP laptops, which are
printed with a small sun icon on the key. The sun icon is filled on the
function key for dimming the laptop. The other key is printed with a
hollow sun icon for brightening the screen.
Press the "Fn" and left arrow keys together on some HP
laptops to turn down the brightness. The "Fn" and right arrow key will
increase brightness. Press and release the right arrow key repeatedly,
while holding down "Fn," to decrease the screen brightness slowly, or
hold the keys to darken the screen as low as the setting will go.
For HP Monitors
Press and hold the down arrow key on the front panel of the
monitor below the screen to turn down the brightness on the external
monitor to the lowest setting.
Repeatedly press the down arrow button to dim the monitor gradually.
Press the up arrow key on the monitor to increase brightness.
Reinstall all drivers for your laptop from the HP.Com website. If the function keys still don't work, you may have a defective keyboard.
Turn the laptop off, then take the laptop keyboard off (usually takes 1 screw - bottom of case, and a few sliders, top of keyboard). And then there will be a couple of thin cables which are connected to the motherboard. There is a sliding connector which holds these on. Push this up, slide the cable in, puch it back down. Do for both cables if you have 2 (keyboard and tracking pad/pointing stick). Reinstall keyboard and try it out.
If that doesn't fix it, replace the keyboard with one from ebay.
This is normal for almost every laptop - it is to conserve battery power. However, if you want to adjust the brightness anyway, you can do so by holding down the "Fn" key, and then hitting the number key that has the blue 'brighter sun' making on it. This is usually the F8 key, with the F7 key being the less bright key.
