Question about HP Pavilion dv4000 Notebook
It's making 3 beeps, one long, then 2 short, like beeeeeeeep, beep beep. It will stay on with a black screen (no backlight, no image even looking at it with a flashlight, so not a backlight issue).
This POST error code maybe -
one long, two short beeps

Testimonial: "I had already thought of that, but since I couldn't find any notebook beep code charts (there are plenty for desktops, instead) I asked for confirmation. This seems to be video card related. I think I'll just ditch this old notebook and get a new one. Thanks anyway."
These are the problems that occurring no display.
1. Defective memory
2. Defective Video graphic card
3. Defective processor
4. Defective motherboard

I had the same problem...
The solution is only temporary and you will have to reapply it after around 5 to 6 boots cuz it'll just happen again (the beep syndrome).
Just heat up the laptop by turning it on and covering its air vents with your hands.
Then after you hear the beeps turn it off.
Turn the laptop on again and immediately turn it over upside down with the lid closed ofcoarse (simply put it on its back).Hopefully you wont hear the beeps and when you open up the laptop lcd...voila display.

Hi, you need do follow things:
1) check RAM in the back small cover of laptop, clean RAM pins and slots set back or change RAM position each other ,or replace other RAM(same model) if old RAM not works.
2) take out the wireless card in the back small cover that is MINI PCI slot, then turn on. sometimes it cancause this trouble.
help you fix it, and any question keep in touch please.

I had the same problem, i found it was because my RAM stick was installed loose. I removed and fixed it again properly.
Issue was sorted.
