There was a recall on the Pavilion dv9000 series of Notebook PC's. This has passed.http://www.nvidiasettlement.com/index.htmlThe problem is the graphics chipset COOLING.To be more specific, it isn't a problem with the graphics chipset itself, (Nvidia), it is the COOLING of the graphics chipset.HP's problem.Allow me to explain, and show you the cooling system for the Pavilion dv9000 series of Notebook PC's; (If you are not familiar)1) Chipset:Chip and Chipset are slang terms for I.C.Integrated Circuit,http://en.wikipedia.org/wiki/Integrated_Circuit2) GPU:The Graphics Processing Unit, or GPU, is the graphics chipset,http://en.wikipedia.org/wiki/GPUThe GPU for the HP Pavilion dv9815nr is an Nvidia GeForce Go 7150M,http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01394734&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=36898933) The cooling system consists of the Fan Assembly, Heatsink, Cooling Tube, and Thermal Paste.The Cooling Tube is a slightly flattened copper pipe, sealed on both ends, and filled with Nitrogen gas.It has two metal small plates attached to it.One small metal plate sits on top of the Processor. The other small plate sits on top of the GPU.Heat is absorbed by the small metal plates, and then absorbed by the Cooling Tube, from the plates.Heat is then transferred to the Heatsink. A thin, small metal plate, with Tall, thin fins protruding from it.The Heatsink absorbs the heat from the Cooling Tube. Then heat is radiated away from the Tall, thin fins. The air flow from the Fan Assembly helps to carry heat away from the fins.The small metal plate that sits on the GPU is too Small. The small metal plate that sits on top of the CPU (Processor) is barely adequate in surface area size, also.This means the GPU will overheat. With constant overheating the mounting of the graphics chipset, (GPU) will loosen.The graphics chipset is mounted via a BGA surface mount.Allow me to explain the BGA surface mount;Compare to an older Pentium 4 desktop computer processor, that uses a Socket 478 processor socket.The processor has 478 contact pins on the bottom side.The processor socket has 478 matching socket holes.With a BGA surface mount there are no contact pins, nor socket holes.Solder Balls take the place of the contact pins, and Copper Pads take the place of the socket holes. (Or Processor socket)The chipset is set into place, with the Solder Balls lining up with the matching Copper Pads.Heat is then applied at a specific temperature, and length of time.This melts the solder balls, and solders the graphics chipset to the copper pads. (To the motherboard)With constant overheating the solder connections start to partially melt.This creates poor contacts.This is what you are seeing.This video explains, and shows the problem. (Also the cooling system)It is posted for reference ONLY, and not advertising for the video poster,http://www.youtube.com/watch?v=bnkQNmKauEc&feature=pyv&ad=5823851286&kw=DV9000For additional questions please post in a Comment.Regards,joecoolvette
You can not know the motherboard serial number it-self without opening the computer... But you have your product ID and computer serial number on the back of the laptop. That should give you, at the HP Support web-page, the drivers list for your specific built. Knowing the driver, you can know what chip-set it's holding, and so, the motherboard also.
There's a possibility that the problem is just the software side and there are two option that you can do for you to be able to fix your problem. This is gonna be a bit complicated since were going to access your registry, but just follow all the steps and it will be much easier
1. Click on START
2. Type REGEDIT on the search bar on START Menu on the Run Box
3. Expand HKEY_LOCAL_MACHINE
4. Expand SYSTEM
5. Expand CurrentControlSet
6. Expand Control
7. Expand Class
8. Click {4D36E965-E325-11CE-BFC1-08002BE10318}
9. Look for the Upper Filters / right click on it / click on Delete
10. Look for the Lower Filters / right click on it / click on Delete
11. Restart PC
12. Try you CD / DVD ROM
If nothing happens, click on this link then click on RUN and follow the steps, then restart computer and try to run a disc again, if still nothing happens, theres a possibility that the problem is with the hardware side or the media player that you are you using...
Hope this will help...Thank you for using Fixya...

Your video device cannot be detected because of the reason that you havent installed the driver for your webcam.
After you install the drivers, you can now use the webcam. If you want to be sure if you have installed properly the webcam. you may see a Videodevice when you open your My Computer. if you have windows xp or vista installed .
I have to agree with them if you tested everything else. It could most likely be a mother board issue. It would benefit you to purchase another computer and not try to replace the mother board if its NOT under warranty. That MB will be expensive.
Hi You're probably right about the video chip. Seems a lot of HP laptops have this problem. I've repaired many. Most we repair using an oven type of device which remelts the solder all across the motherboard. I have fixed a few using direct heat on the video chip. This is a very delicate procedure and should not be attempted without the proper tools. To individually heat a chip to melt the solder I isolate and insulate the chip. Now I apply heat to the chip using a high velocity, high heat hot air gun. I monitor the heat applied to the chip using an infrared temperature sensor. The solder melts at @ 200 degrees.. Once I'm satisfied that the solder has melted I let the chip cool down naturally. Unless you really feel brave I would suggest taking it to a reputable repair person. By the way, I've read that there's a class action law suit on certain HP models. Might be worth checking out.
to check for CPU temperature (should never be higher than 70 C)
If it's overheating, you may need to clean up dust and lint from your laptop. Turn it off, remove the bottom cover and blow compressed air. Replace the cover, restart and try again.
dear danese, try to update you webcam driver, go to my computer properties, open the hardware tab, click on device manager, push the button on 'Scan for hardware changes'.. wait until you see the yellow circle with big black question mark. right click on it, on context menu choose update driver, (Please note that you have to connect to internet to solve this!). The web should automatically download the driver you need. save it and keep in your favorite folder for your future reference! Try now!
HP X13-04657, is 2007 PC THOSE this PC has CCFL back lamp strip that is dead.Vista era PC, laptops. are hard to work with now, 17 years old.is this not a HP COMPAQ presario HP X13-04657 (wrong name!) sorry !became HP in 2002. so is HP but manuals are super hard to find now. that x13 is part of the microsoft license code vista. (so is distraction to what it is)the real name of the Laptop is and was Presario CQ61 laptop CQ61 the PC has bottom sticker that shows the real names of PCs.CQ61-219TU is real name of on CQ61, there area many different sub codes, and they are not all the same.CQ61-306AX this had CCFL (cold cathode florecent lamps) that love to fail 3 waysdead, blinks ,dime or yellow = white.was made until 2009 and evolved, to LED backlamps.-410 is CCFLI will answer for CCFL as those just love to fail,but the the test is so easynow the answer for ANY laptop this old. 2007 and older. black screen all the time, and BIOS screens dead, answers only me. here. remove the main battery (large) it simply snaps off the bottom.the power pack is next we run the PC on your power pack AC to DC it must make the screen glow with something, do not use the wrong pack as in mixed up with others.now the lap top seems on, even the fan blows, LED glowpoint a flash lamp at the screen ,dark' room , and of you see any kind of LCD data on the screenthe CCFL lamp below #1 is bad.this is phase 1 testing, as other things can fail too. The keyword below is Mercurythis tells me it is those pesky CCFL glow tubes. 2007 is the year some PC went to LED back lamps. yes I was correct the service manual I did find proves they made both lamp types
Central Pin: In many laptop power supply connectors, especially those using the barrel-type connector, there's a central pin that carries the voltage (typically around 19 volts for most laptops) to power the device.
Voltage and Polarity: It's crucial to ensure that the voltage supplied by the power adapter matches the requirements of your laptop. Most laptops operate on 19 volts, but there are exceptions, so always double-check the specifications of your laptop and the power supply.
Polarity: Additionally, the polarity of the connector is important. The central pin typically carries positive voltage, while the outer sleeve of the connector is the ground (negative). Reversing polarity can damage your laptop, so make sure the connector is inserted correctly.
Safety: Always use the power adapter that came with your laptop or a compatible replacement from a reputable manufacturer. Using an incorrect or incompatible power adapter can not only damage your laptop but also pose safety hazards such as overheating or electrical fires.
Replacement: If you need to replace your laptop's power adapter, ensure that the new adapter provides the correct voltage, polarity, and wattage for your laptop model. It's often safer to purchase adapters from the laptop manufacturer or certified third-party suppliers to guarantee compatibility and safety.
