HP dv9000 wireless problems

[AdamsAPlus]

I have a pretty weird situation.

I am working on a HP dv9000. We did a restore to factory setting on it. Now I can't get the wireless to work. Now one of the guys I work with said that the wireless would work for about a min and then it would stop.

I checked the device manager and it doesn't show a wireless card installed. It shows the NIC card and then 2 Bluetooth cards. I have swapped out the wireless cards for a known working one from another dv9000 and then a known working one from a dv6000.

I have googled this and found that several people have problems with the dv9000 wireless. But when they do the Wireless switch on the front of the laptop shows Orange. On this one the switch shows blue, meaning it is working. Something else that is weird is when I turn off the switch, it actually turns off one of the Bluetooth devices.

So I figured I would uninstall the Bluetooth drivers. (mind you that there is nothing hooked up to the laptop) Well Vista re-installs the drivers automatically, as fast as I can uninstall them. I know its got to be a driver issue. But when I go to the HP website and download/install the Wireless drivers, nothing happens. Like I'm installing drivers for a device not connected.

Has anyone else come across this?

This is typical of the dv2000, dv6000, and dv9000's. It's one of the issues that they had. It's related to the nvidia chipset/gpu issue. I've found that reflowing the thing will sometimes cure it.

Otherwise, just have them use a usb wifi adapter.

hmm, I dont see the chipset being the issue "if" it worked before you nuked it.

Is it disabled in the BIOS? go to driveragent.com and do the webscan, and see if it shows any bad drivers.

It's one we have in the shop to sell. I would like to sell it 100% working so we can sell it for a higher price.

What do you mean by "reflowing"

I have fixed several with the Video problem by using a heat gun on the video card. But this is the first time I have ran into this.

make sure HP wireless assistant is installed if that still doesnt do it it could be the HP/nvidia issue. The internal port on the HP will die just like that working one second then after doing something completely unrelated it stops. I've had the Wireless fail after swapping the dvd drive with another one for testing.

the DV2, DV6, DV9 are not worth the trouble

I personally didn't have the laptop before it was nuked so I'm not sure if it worked or not before it was nuked

It had the wireless assistant on it. I read somewhere that it may cause the problem so I removed it during troubleshooting.


I agree its not worth the trouble but we have it and I would like to make some money off of it. I wouldn't but one. I think we got this one on a trade.

That is reflowing; when you heat the solder up to a point in which is liquefies and reforms the bond with board and the GPU. I wouldn't exactly call this a "fix" though, as it doesn't do anything to address the underlying issue.

 

[AdamsAPlus]

OK, This is what I have done to the dv6000 and dv9000 when they had video problems. Which seem like a lot. (It was such a bad design.) I just didn't know the term for it.

Ok I'll try and do the same with the wireless connectors.

Anyone got any ideas why there would be 2 bluetooth card drivers and why when you turn off the wireless switch it turns off one of the bluetooth cards? Could there be a bluetooth card in with the wireless card?

I would part this laptop out on ebay and be done with it.
I wouldnt sell a dv9000 or dv6000 due to the commmon overheating issue.
Reflow may work, but it still has the same flaw, thus could fail again who knows how soon.
So you wouldnt want to warrenty it.

My thinking is if I wouldnt want to warrenty it, I wont sell it to my customer. So I part out all but the mobo on ebay. You might be surprized how much you can make doing that

(on the other hand I might reflow and use for myself, LOL)

That's why I'm practicing the beautiful art of reballing.

How are you doing your reballing? Do you have a stencil set that allows you to apply new solder to the gpu? I've considered buying a set, but I don't know how easy they are to use.
I'm also having a really hard time figuring out how to get the red epoxy crap off of the gpu without damaging anything.

Right now I'm just working on XBox's and I'm just using preforms, but eventually I'd like to get a stencil set. I haven't come across one with the red epoxy "fix" yet.

looks like the southbridge chipsets needs the reflow/reball.

GPU - no video
chipset - USB and wifi

I will try that. I now know it's not a driver issue because the wifi started working. It worked for like 8 hours. It showed up in the Device Manager. Then it stopped again and disappeared out of the Device Manager.

I really dislike these dv's. In fact I really dislike the HP's and Compaq's. Love their printers but hate their computers.

Take a look here, be careful and ensure you shim it otherwise the problem will return. These laptops are renown for their poor design.
