Having problems with your HP Pavilion dv1000 Notebook ?

HP Pavillion power link blinks

\015 Hi,I have an HP pavillion DV1000 laptop, and it seems like there is some problem with the power supply. Every time i plug in the power supply, the laptop screen and the ac adapter light indicator starts blinking (on for 1 sec, off for next). Screen has a different brightness setting for connected vs not connected to power, and i am pretty sure that's why the screen is toggling between the 2 power setting. It looks like there is something wrong with the power supply as if some connection is loose, it keeps toggling between connected and non-connected.The laptop does boot up and i can work on it, but its really annoying, and ofcourse it takes a long while to charge it up, (as the AC adapter keeps toggling between charging and not charging).I have tried using 2-3 different power supplies (the big brick and the cord), but the same issue. The adapter connection doesn't look to be loose, so i am not sure what the problem is. Any pointers/help would be really appreciated.Thanks\015

Answers :

I have a DV1130us and I'm having the same problem. I've already replaced 2 blown SMD capacitor on the motherboard, originally would only short out and obviously not boot or charge.

\015\012But I think it may be the MAX1907a chip, basically the actual power supply controller for the laptop, though it may also just be another bad cap somewhere. If/when I get mine working I will post what I did to get it to charge.

\015\012I can almost guarantee you this is an issue with the power jack on the laptop's motherboard. Even though it may not appear to be loose, its most likely the solder connection on the motherboard has broken, only allowing intermittent connection when the laptop is in /just/ the right position.
\015\012
\015\012It'd be best to get this looked at sooner rather than later, preferrably if the computer is still under warranty. The connection will steadily decline, until the laptop is unusable.
\015\012
\015\012Otherwise, let me know if you want to get rid of the system! I have a system, almost exactly the same model, that I need parts for!
\015\012
\015\012Hope this helps!

My HP Pavilion dv9005us has two issues which I cannot resolve. The wireless device is not even recognized or detected by the computer, and there seems to be an electrical problem where the lighted buttons at the top flicker on and off from time to time, which may also be linked to an issue where the computer will at times refuse to turn on after I press the on button and watch it all light up in response and immediately shut off. Any help with this would be greatly appreciated.
