Re: hp dv2000 won't turn on...
Older Laptops can get lots of dust inside from the fan system designed to cool it. You may have a bad connection between your main board and the display. I have seen that cause eratic behavior on some systems. Since you mentioned that it does work from time to time normally, I would be more inclined to think you may have some problems with the lcd display..When it does come on, have you moved the display around ( meaning open and almost close the cover) to see if the display fails to work when you do that? As I mentioned earlier, you could have a signifiacant dust buildup inside the system and dust tends to cause intermittent shorts to the circuitry which may manifest itself as sporadic behavior. If and when the system comes up, I would strongly encourage you to create back up copies onto cd's/dvs's or an external usb drive so that you don't lose it if your laptop dies for good. Hope this helps a little.. Good Luck !

There is no reset button on the dv2000.To reset the laptop remove AC power and battery,hold down power button 30 - 60 sec,plug in AC power only and press power button.This method is called a hard reset.If all goes well shutdown - remove power - replace battery and job done!
Normally is because the battery is empty or in an error state.
If you plug the power cord and the led still blinking, disconect everything, turn your laptop and search how to take out the battery, wait 1 minute then replug it again and try.
the hp dv series notebooks have had recalls for defects of not booting up from faulty motherboards and having to do bios updates, they have all the reacalls and problems on the hp support website hp.com
remove the battery and the power from the laptop.....then press and hold down the power button for 20 seconds ...... attach the AC power only and turn on the laptop this should turn on the system. This drains the capacitors on the system (safety feature of laptops ... quite common)
If this does not work remove the Ram and reseat it ... something has either come loose or the backlight on the LCD has gone bad.
Could be a glitched battery. Turn it on without battery installed. Also, to eleviate the memory - take it out. The unit will still turn on. I have to go along with HP support, that's it's probably the mother board. Now all is not gloomy. Hp has extended their warranty on many models, Dv2000-Dv6000 to name a few. Ask for a supervisor.
System does not power on and the LEDs on the front of the computer are not flashing. System unable to power on. Press and hold the power button for less than 4 seconds. If the hard drive LED turns green, then: 1.Check that the voltage selector is set to the appropriate voltage. 2.Remove the expansion cards one at a time until the 3.3 V_aux light on the system board turns on. 3.Replace the system board. OR Press and hold the power button for less than 4 seconds. If the hard drive LED does not turn on green then: 1.Check that the unit is plugged into a working AC outlet. 2.Open hood and check that the power button harness is properly connected to the system board. 3.Check that both power supply cables are properly connected to the system board. 4.If the 3.3 V_aux light on the system board is on, then replace the power button harness. 5.If the 3.3 V_aux light on the system board is off, then replace the power supply. 6.Replace the system board.
I have the HP pavilioin dv2000 too. I encountered the same problem. I did everything i though possible (reseated the battery, reseated the ram) and everytime i hit the power button, i would get all the blue lights on but no screen. And it is non responsive. Fed up i held the power key down for no less than 2 minutes and ta-da the computer responds by turning off. After i pressed the power button again, it started normally.
