Question about HP Compaq Presario R4000 Notebook
Ok on your keyboard there should be some way to adjust the brightness just plug in the laptop and adjust it to what you want then unplug the laptop and adjust it to what you want and it should keep that setting. if that does not work you can check the bios settings some laptop bios' have a brightness option.

Tips for a great answer:
Make sure the machine has power.
The battery might be dead, so connect your notebook to the AC power adapter and plug the adapter into a working AC outlet.
If you have a power strip or surge protector, make sure it is on.
If you are having trouble with battery power, recharge it if it has been fully discharged or replace it if necessary.
Check to make sure the computer is not in "sleep" or "hibernate" mode.
Press a key or the touchpad and wait for it to respond.
Try pressing the power button.
Make sure that you fully engage the power button.
You should press and hold the button for at least half a second but no more than three seconds for the machine to power on.
Adjust the screen's display brightness because it may be too dark. Press and hold the "FN" key and press the key with the icon to increase brightness.
This icon looks like an "up" arrow and a picture of the sun.
hope this helps
