    My screen went dim and so I located an inverter and replaced it. The screen was working again.

    Then something wierd happened. The screen started going dim after a little while when the machine wasn't plugged into AC. When it was plugged into AC, everything was fine.

    So, when the AC is not plugged in, often it will run a few minutes then go dim. When I restarte the computer, I get a few more minutes of the screen working, then it goes dim again. What is happening?

    Hey, I have a similar problem with my HP nc6120. The screen broke a few months ago, but i was still able to use my laptop with an external monitor. It appeared that the backlight had gone as I could just make out what was on the screen. It boots fine and works fine just not light on the screen. Anyway a few months later it started working and was ok for about a month but now its gone again. Would it be the backlight or inverter causing the problem? What is an inverter also? Thank you very much

Having the same problem with a HP 530 laptop

I'm not sure but think there might be an issue with Vista and the display, surrounding sleep/hibernation

Returned the PC to HP and they replaced the inverter and updated the bios, which worked for a day or two and then the problem reoccured.

A few days later started it and it worked okay, until I closed the lid, which should have done nothing (as per vista control-panel settings), but obviously did because the screen has gone very dark again, I guess indicating that vista is not sending power to the inverter/backlight?

> Works fine attached to an external monitor.

Well, first off, do you get a screen (external or onboard) if you boot into the bios? If you have no video whatsoever, the only thing that would start working again after time off, then stop, would be the video module went. slowly, but it went.

Main cause is overheating, caused by the heatsink/fan becoming clogged up.

What makes you think the backlight was the problem BTW? Sure it wasn't just the inverter?

Let me know if you can access bios?

Good luck

Dim screen on HP. Any diagnostics I can run to isolate the problem?

The problem is in the inverter board, "located below the screen" or the backlight behind the LCD display is faulty. In most cases the inverter is the issue and replacement only option, "be aware that high voltage is present when running"

I have hp pavilion dv6000 laptop, problem is that only 10 minutes is working batary after that again i have to connect power

Hi, It sounds like the battery has come to the end of its life and you will need to replace it.

Most laptop batteries in my opinion only last 18months to 2 years before they need replacement, this is common to most all laptops.

hope this helps.

Screen dim HP pavilion dv1000

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.

Screen turns blank all of sudden and works normal after switching of the system for 1 hr or so.

You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

I have an HP DV9074CL Pavilion laptop that won't boot

I bought mine in April 2007. This happened June of last year and they replaced it for free. It just happened again 2 nights ago and HP won't do anything. My fiance called them and got a case manager and said that they design their laptops to work for only 2 years to which I say if it's designed to work for 2 years, shouldn't my motherboard still be working? After this experience and numerous other problems I have had with this laptop, I am never buying an HP product again.

Getting noise in HP dv2700t 14" laptop

I wonder if the controller board on the motherboard is bad. I'd report it to HP again and see if they can fix it for you. Obviously they switch vendors for getting hard drives.
