HP DV6000 Won't Power On!

[buyguy123]

DV6000 laptop won't power on at all - no lights on the quick bar, etc. Only light is the blue ring around the power input when the plug is in. I read posts and watched you tube videos about the power and screen issues. So far I replaced the power ribbon from the motherboard to the power button. It did not work except for now,the lightning bolt power indicator lights up, light is steady - not flashing, but only when the battery is in and the unit is plugged in. When the battery is out and unit plugged in - no light.

I read that it could be the USB/Power card, the battery, the graphic chip on the motherboard or the board itself.

Any suggestions?

Thanks!

I have some experience with these HP models, have you tried to hard reset the laptop? (i.e. taking the battery out, unplugging it and holding the power button for 15-30 seconds). What they don't tell you is that sometimes you have to hard reset these HP laptops 10-15 times before they start up again, something is wrong with their standby/deep sleep modes. Do you know if there is any charge in the battery left? If there is a charge left, then the laptop should start up (obviously) without the adapter. The first thing you might want to do is get your power adapter tested, since it may have gone bad and might not be able to charge/run the laptop anymore. It sounds like you have a power issue but if your power adapter checks out, there is a chance that the graphics chip desoldered from the motherboard.

I apologize if I am a little unclear; I am trying to write this before I leave for out of town for the day, so my english may be a little garbled. I do think that your issue sounds like the power adapter/power card, but the graphics chip failure also mimics the same symptoms. If you are able to get it started again and it fails after a few minutes of use, the graphics chip probably became desoldered. It is possible to reflow the solder, but it's a real pain to do.

Does it have the discrete Nvidia graphics? These are the ones that have the issue with the solder balls desoldering resulting in a black screen from what I've heard, although I thought they would otherwise power on with just the screen being blank. The ones with discrete ATI graphics may also have this issue.

Laptop was not working at all, but the sticker says that it's an NVIDIA GeForce Go 7150M. I have tried to pull battery and power cord and press power button for 30+ sec and nothing. I switched the power cable and used the one from my old HP NC6120, (which has same plug tip and is same model) and with the battery in, I only get the blue light around plug input and lightning bolt steady blue light. If I pull battery, lightning bolt goes out. How can I test the battery and the USB plug card to see if they are ok? If this was the video card wouldn't the laptop go on for a sec and show all of the lights on? The quick bar does nothing at all - no lights. I did check the battery recall list and my battery # is 65035. But if the battery was no good, would I still get the lightning bolt blue light?

I have dv6000 and this notebook had two big problems. At first it didn't work at all (my father told me he "resurrected" it). So I guess something similar happened to my notebook as well. Unfortunately I don't know what was changed. But I believe it was something with Nvidia graphics card, as Kuschelweich had mentioned. Then after the fix, this notebook had this weird thing when it got "stuck" sometimes. You browse internet casually and the computer just freezes, you can do nothing for 10-50 seconds. Then it works fine again. Really annoying. What helped me with that was I downloaded Driver Genius and updated ALL the drivers of this computer. After a restart, it worked flawlessly.

sorry, I thought i uploaded my last post:
It sounds like the battery is working, it might be the graphics chip or it might be the power connection to the motherboard. The nvidia graphics issue was that the HP laptops had a flaw in which the heat sync was attached to the graphics chip in such a way that the thermals on the chip was so terrible that the graphics chip desoldered from the motherboard like Kuschelweich had mentioned. I happen to have a HP DV2000 series that had this same issue and would refuse to start, just as yours; the laptop would start its fans up briefly ONLY after I did the "hard reset" (pull the battery and power cord, hold the power button for 15-30 seconds and reconnect everything) about 10-15 times, if i didnt do this, it wouldnt start at all. It would run occasionally for about 10 minutes and shut off. What I ended up doing was tearing it apart, reflowing the graphics chip with a heat gun, some quarters on top of the heat sync to dissipate the heat and aluminum foil surrounding the chip to prevent other spots from getting reflowed. I then took a piece of copper (a shaved down penny from when they were still made of copper) and some acrylic silver 5 and "fixed" the gap in between the graphics chip and the heat sync. The fix ended up working about 6 months.

Those laptops are pure junk. I fixed one for a customer (new motherboard because the nVidia chip was burnt...), and it was a pain to put back together because they're so cheaply made. I've probably seen 8-10 laptops with this same problem in the last 2 years...

Now I tell people to cut their losses and get something else.

I've had two of those: One with an AMD processor - touchpad failed, battery failed suddenly, then the whole thing failed, similar to this case, and one with an Intel Core 2 Duo - needed a new hard drive (even refused to boot due to a SMART issue, drive was still operational enough to extract data), the touchpad indicator LED stopped working, battery failed prematurely. Also, both power bricks failed relatively early.

Basically, the crappiest things I have ever seen.
