The display on my HP Pavillion dv1000 is extremely dim and I can't get the screen to lighten so I can read it. I have done a hard reset and replaced the power inverter. It blink on once, but that was the best I could get.

It would be hard if I type it here. It's better that you can see it.

There are a lot of tutorials in Youtube. I'm pretty sure that you can find one from there.

Two things: video card issue or video card settings. Try to go to the power options configuration of your portable system. Adjust the brightness. If changes does not take effect on your portable's display as well as the external monitor, it is a video card issue. The last option of resolution is to re-install the video driver. Click the link below and choose the exact model of your computer. Try to download the video driver for your computer. Make sure that you have the correct driver for your operating system. If re-installing the video driver still fails, unfortunately you need to have your video card replaced. Usually the video card comes embedded on the motherboard. That means you have to have your whole board replaced.

The lid actuator switch may not be working correctly. It's a small switch above the keyboard and led's on either the right or left side. Try pressing it 2 or 3 times to see if the display starts working correctly again. If so, it will need to be replaced.

If that doesn't work, you can also turn it on with the ac adapter plugged in. After it boots, press the power button and hold it in until it shuts off and then turn it on again and see if the display has returned to normal.

If neither of these options work, your laptop may need to have the backlight replaced.

It may not even be caused by the graphics display driver at all. Your Hard Drive may hae BAD SECTORS and the computer is battling to read the system area of the hard drive... Make alse sure that the hard drive commections are fine
