Re: faulty backlight hp laptop

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.

Re: faulty backlight hp laptop

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

HP paviilion a1113w constantly powering down

Sounds like it is overheating. Computers overheats because of:
1) Dust - Dust inside the computer, Dust clogging the fans, dust clogging the vents.
2) Fan not working
3) The Thermal Paste on the CPU and Heat Sink has dried up or is too thin to keep the unit cool

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.

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.

Can you try booting to an external screen? If it works with an external screen, sounds like either the inverter (probable) or the backlight has gone out. If there's no image on the external screen, it could be any of several things, the most likely of which is the video module.
Sounds like you got a lemon. The DV series have been good sellers, and mostly good units.
Good luck
