Question about HP Pavilion dv9000z Notebook

1 Answer

Motherboard My video adapter went bad on my hp dv9074cl I just want to know what other motherboard can I install or does it have to be the same one it has My dv9074cl blue screened one day while just sitting there idle, and now video memory appears to be corrupted. The 0x bluescreen error I get if I try to boot normally seems to agree. I have a recurring pattern of dots/lines at boot (POST) and in the BIOS setup program as well. Win-dohs (XP) will boot in safe mode (with a similar pattern of video corruption) but not in normal mode (blue screen crash occurs). HP support recommended updating the BIOS but there isn't a BIOS update listed on the support page for this model. Doh! This sounds like a widespread problem related to the Nvidia graphics board, which is unfortunately built-in to the motherboard. :-( My dv9000 (a dv9200 cto, to be exact) developed this problem when allowing WindowsUpdate to install the newest video driver (it showed up on WU around Dec25th, 2008) and following a number of crashes it bluescreened with errors that at times point to nvlddmkm.sys being corrupted, or just refusing to System Restore, Startup Repair, driver rollback, etc. In general, it will install drivers but they will BSOD with typical memory errors, unless F8 into safe mode, then uninstall nvidia driver and allow the generic VGA driver to take over. This notebook is an x86 centrino duo @2.0ghz, Nvidia geforce go 7600 256mb, BIOS F2.c running Vista home premium 32bit. It looks like the only way to fix this is to send it back to HP and get the video card repaired/replaced.BTW, I'm not a gamer, only use it for PS & LR and have kept the fan & vents (fairly) clean.

    I have the exact same problem. I have a dv9040.

    One day, out of nowhere I got he BSOD (blue screen of death). Took it to a place to have it fixed, they told me it would be expensive. Just under $600. The video card is shot and they are built into motherboards on laptops. So it's not that simple to fix.

    I am running in safe mode right now. Backed up my files.

    Hate to tell you, but as you can see it is a costly repair and may not even be worth doing....look to buy another laptop instead.

    This laptop has been nothing but problems for me.

    Spoem, it's a worthy idea, but remember that these notebooks have very specific drivers that are tied to the configuration that shipped as a package, i.e. motherboard and video card. This means that Nvidia will only let you pick drivers for the standalone card that is a closest match to the one in your laptop, when not outright boot you to the notebook manufacturer's sales website. If you go to the (in this case) HP home support site, then punch in the part # then you get very specific drivers in the proper driver download page. When the drivers don't install, or install and BSOD on startup, you can only do (according to HP Support) a destructive system restore that attempts to restore from the recovery partition all the system files, erasing my data in the process. So I have to do a fresh backup and/or run in safe mode until I can part with this piece. Also, the Windows Update site help is no use, they appeared to me as less than knowledgeable and did little to try to determine if this is a hardware or a software issue. BTW, I can't cancel out of auto driver install when I do the uninstall of the video card, as Spoem suggested. I had tried that (unistalling the display adapter) as my first course of action, and that is how I've been able to even boot in order to trobleshoot.

    Best Buy supposedly put in a new motherboard, and I'm still having the issue. I finally just turned off my video driver and it works better...just can't play any games. I've been told my model (HP Pavilion ze4900) has this issue with their motherboards.

    I tried the above and it says I already have the latest updated driver.

MS seems to have a theme going with updating drivers that cause problems. Try this . . .

Go to www.nvidia.com and download the latest driver package. You may need to run in Safe Mode with network or use a different computer.

Go into device manager and uninstall the graphics card.

Restart the computer. Cancel the installation of the new hardware when it comes up. Run the setup file that you downloaded from nVidia.

Restart the computer.

Good luck and please let me know how it turns out!

Hp dv6-3160ss white screen


Totally white or just no picture at all. If that is the case you could have lost your Operating System re-install it. Or your video card went bad or the lamp went bad or the screen itself went bad or the motherboard went bad. You will know for sure if you try to reload the Operating System or do a recovery disk. This may be a situation where you may have to take it in for repairs or a diagnosis. I suggest that before going any further with this especially if your not a tech type person. John

This is a sign of a bad video display adapter. Depending on your laptop model, if this adapter is integrated int the motherboard, you will have to replace the motherboard. However, if it is a daughter board that fits into a slot on the motherboard, you will only have to replace this daughter board.

Whilst in use went completly dead canot resart


Laptop is dead. How to troubleshoot the problem.
In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops.
Let’s take a look at two different scenarios.
Example 1. The laptop is absolutely dead.
When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LEDs will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead.

What you can do in this case?
1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet.
2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter.
3. Let’s say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again.

OK, you tested the adapter and it’s bad. If you decide to replace the original DC adapter with a generic one, you’ll have to follow this rule:
The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher.

If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It’s possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you’ll have to disassemble the laptop and replace the power jack.
Example 2. When you plug the DC power adapter and press on the power button, the laptop starts making normal noises, the LEDs work properly but noting appears on the screen. The laptop will not start.
First of all, take a closer look at the LCD screen. Look at the screen under bright light. It’s possible that the image is still on the screen but it’s very faint.
If there is no image on the laptop LCD screen, test the laptop with an external monitor. Connect an external monitor to the VGA port on your laptop and turn the laptop on. You can toggle video output between the internal LCD screen and external monitor by pressing Fn and F4 keys simultaneously on HP laptops, Fn and F5 keys on Toshiba laptops, Fn and F7 keys on IBM laptops. Other laptops may use different key combinations.
Let’s say the external monitor works fine but the internal LCD screen has no image at all. If that’s the case, your problem could be related to the LCD screen or the video cable. Also, make sure the video cable makes good connection with the motherboard and the LCD screen. Try reconnecting, reseating the cable.
In my case, both internal and external monitors were absolutely dead. Neither of them had image. That means the problem is not related to the LCD screen or the video cable. From my experience I know that this problem could be related to the laptop memory.
Try reseating the memory module, maybe it’s not making good connection with the memory slot. Try cleaning contacts on the memory module with pen eraser. Try moving the memory module into another slot. Try replacing the memory module with another known good module, it’s possible that your original module is dead.
If you have two memory modules installed you can try removing them one by one, it’s possible that one of the modules is bad. Try installing different memory modules into different memory slots.

In my case reseating, swapping the memory module didn’t help. I was pretty confident that my problem is not memory related and I moved on.
Try removing battery, hard drive and DVD drive and turning on the laptop without these components.
Also, try turning on the laptop with an external monitor when the video cable is unplugged from the motherboard. If the laptop start with video on the external monitor, apparently there is something wrong with the laptop display panel.
Finally, disassemble the laptop and removed the motherboard.
1. Motherboard. Like on most laptops, in my case the video card is integrated into the motherboard
2. CPU with heatsink and cooling fan.
3. Known good memory module.
4. The power button board witch you need to turn on the system.
5. Working DC power adapter.

Still cannot get any video on the external monitor. The system turns on, the cooling fan starts spinning but there is no video.
At this point I’m 95% sure that the motherboard is dead. CPU failures are not very common, so it must be bad motherboard.

I am unable to engage the wireless assistant - the wireless switch light is orange and can not connect


hey there, first thing you need to do is check that the card and drivers are installed. Right click my computer=> properties=> hardware=> device manager click on the plus sign next to network adapters and check that there is a WLAN adapter and check that there are no yellow question marks. If there is an adapter there, right click on it and uninstall it. Reboot the laptop and it should reinstall the driver on its own. If it does not, go to the following link and get your driver. Just put in your prod number (ie dv9074cl) click on driver downloads and pick your operrating system and it will pull up a list of drivers for that laptop. Just find the wireless drivers, download and install them. Let me know if this helps you. These laptops also are famous for overheating and the wireless cards going bad. The heatsink fins are located in the back left corner and need to be blown out with canned air on a regular basis. Also, when you are in the driver list make sure you at least update the bios to he newes version. This will help with the overheating prolem slightly (fan control) Let me know if you are still stuck or need anything else.

I have an HP DV9074CL Pavilion laptop that won't boot


I bought mine in April 2007. This happened June of last year and they replaced it for free. It just happened again 2 nights ago and HP won't do anything. My fiance called them and got a case manager and said that they design their laptops to work for only 2 years to which I say if it's designed to work for 2 years, shouldn't my motherboard still be working? After this experience and numerous other problems I have had with this laptop, I am never buying an HP product again.

Generally, the graphics card on most portables is not a upgradable option. Researching on HP spare parts, that appears to be true on this system.

HP support are correct sometimes this problem can be eliminated by a bios update. I can help you with that. firstly find out what model chipset (which is most likely an intel chipset) your system has and from there you can download the appropriate bios updates from intel.com. If you have a problem finding out the chipset let me know and I will look for you.
