1. Check the adapter
2. Check the processor
3. Check the motherboard if defective replace new one.
Note: You need to know the right spare part number of your motherboard e.i 443776-001. Here's a sample video
Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.
click start right click on computer select properties then device manager scroll to sound and video game controllers if you see a yellow question/exclamation mark or a red X the driver will need to update drivers

right click on the speaker icon in the bottom taskbar you will see an array of options select
playback devices make sure it has a green tick and the correct speakers are selected
be updated if you computer came with a motherboard disk the drivers could be on it although
once speakers are connected widows 7 should automatically update the drivers
click start control panel hardware and sound manage audio devices playback you might have to set a default go for via high definition audio then right click on speaker
you might have to configure them then select properties you will see tabs general level in this tab make sure your settings are loud enough also enhancements and advanced from the drop down
list in the advanced tab select dvd quality or another then apply
If the power adapter checks out, remove the main battery and try again, if no change the DC jack in the laptop is a common source of trouble from no power to intermittent operation, the next step would be to dismantle the laptop down to the motherboard level to address the issue.
That is because;1) The inside of the computer is dirty. As such the cooling capacity has dropped. The Fan Assembly is trying to keep up with the call for cooling, and has to stay constantly on.OR,2) The laptop is suffering from an 'ailment', that is common for the Pavilion dv2000 series, dv6000 series, and dv9000 series of aNotebook PC's.Specifically the cooling for the graphics chipset. It is INADEQUATE.This leads to the graphics chipset overheating, and loosening the connection of the graphics chipset, to the motherboard.To explain;1) Chip and Chipset are slang terms for I.C.Integrated Circuit,http://en.wikipedia.org/wiki/Integrated_Circuit2) The Chipset responsible for handling graphics, is the graphics chipset, or also known as the GPU,http://en.wikipedia.org/wiki/GPU[ The Graphics Processing Unit for the Pavilion dv6500Z Notebook PC, is an Nvidia GeForce 8400M GS,http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units#GeForce_8M_.288xxxM.29_series It is Integrated Graphics. The GPU is soldered to the motherboard ]3) The Nvidia GeForce 8400M GS graphics chipset, is mounted to the motherboard with a BGA surface mount.To explain the BGA surface mount;Compare to the older Intel Pentium 4 processors, that use a Socket 478 processor socket.The bottom of the processor has 478 contact pins.These line up with 478 socket holes in the Socket 478 processor socket,http://en.wikipedia.org/wiki/Socket_478With a BGA surface mount, there are No contact pins on the bottom of the chipset, nor socket holes on the motherboard. (No socket)In place of the contact pins there are Solder Balls.In place of the socket holes there are Copper Pads.The chipset is set into place over the motherboard, with it's Solder Balls lining up with the matching Copper Pads, on the motherboard.Heat is then applied at a specific temperature, and length of time.The solder balls melt, which in turn solders the chipset TO the copper pads.(Solders the chipset to the motherboard)With the inadequate cooling for the graphics chipset, the graphics chipset constantly overheats.In due time the solder connections start to melt.This creates a poor contact, of the graphics chipset to the motherboard.Explanation of the cooling system, for a Pavilion dv6000 series of Notebook PC:The cooling system consists of a Fan Assembly, Cooling Tube, and Heatsink.A) The Cooling Tube is a slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.At one end it has a small metal plate.One part of the metal plate sits on top of the Processor, and the other part sits on top of the graphics chipset.The small metal plate AREA for the graphics chipset is TOO small.Heat is absorbed by the small metal plate. The heat is then absorbed by the Cooling Tube.At the opposite end of the Cooling Tube, is the Heatsink.The Heatsink is a small piece of metal, with Tall, Thin fins, protruding from it.The Heatsink absorbs heat from the Cooling Tube, and radiates the heat away with the Tall, Thin fins.Air flow from the Fan Assembly, helps to carry heat away from the fins.http://www.insidemylaptop.com/disassemble-hp-pavilion-dv6-laptop/Drop down to Step 28. Here you are looking at a top view of the motherboard, and a top view of the Fan Assembly, to the upper left of the motherboard.Go to Step 29.This photo shows the bottom of the motherboard, and the cooling system.Fan Assembly (Black), Heatsink, (To the immediate right of the Fan Assembly. Black in color. You can barely make out fins running horizontally), and Cooling Tube. (Long curved copper tube looking object)This explains in more detail, and is a video.It is posted for reference ONLY, and not advertising for the video poster,http://www.youtube.com/watch?v=JEpnqhRYGLw(The BEST method is to use a BGA Rework Machine. This way you KNOW the job will only be done ONCE)For additional questions please post in a Comment.Regards,joecoolvette
It sounds like a problem I had. While traveling, my laptop connected with a WIFI network with the same name as my home network.It was my son's. He gave me his password and I entered it on both my machine and my wife's. When I got home I had the same problem. I tried everything including re-installing the WIreless drivers a few times. I could cable connect but every time I tried wireless, it told me to enter a password then came back with "SORRY CHARLIE" Called my son and he said probably the wireless password was written to my registry and my laptop was telling me to give the password. As my router was expecting a different password it wouldn't connect. The cable connection did not check the registry since it uses a different driver set. The registry entry for the router password must be deleted. The only way I knew how was to re-install my operating system. This is throwing the baby with the bathwater. I am sure someone out there knows how to find and erase a Register entry.
For you to be able to resolved this problem, go to HP website and downlaod the latest BIOS from there, just search for the exact model of the laptop and look for the BIOS update.
Hope this information will help. Thank you for uisng FixYa!
You may have helped with the last drop in the "chip creep" effect and broken the contact between the motherboard and the power regulating chip. This is a common problem on Toshiba and HP laptop motherboards, here's how to repair this Maxim 1987 power chip problem. This Maxim chip regulates the voltage for every component on the board, and if it gets desoldered in at least one spot, then the motherboard just won't work. It's basically a design flaw and it's nobody's fault (OK, it's HP's fault), and I'm sure you can pull off the repair, just stick to the instructions.

Try booting off a Windows or other bootable CD. If the system boots, they the HDD just needs to be replaced. Replacement HDD should cost less than $100 unless you buy it from Dell (and maybe even then). From there it is a matter of reloading the system. I will make the assumption that you did not get the restore disks and that there is no way to get them off the drive now. That being said, you will do best by purchasing a replacement recovery set from Dell or off the Internet.
If you want, I will do the labor for $75. You will also need to pay for the parts and shipping.
Yes, if it has failed completely, you should perform a complete repair. If you can get into "Safe Mode" press F8 when first booting,and run "System Restore" or if ya can't do that use the built in recovery mode & repair.
Though first ya can try removing that startuprepairV2 first via add/remove programs in control panel. See if that fixes things B4 resorting to drastic action.
You probably need to replace the keyboard, which is fairly simple. You will need to pop up the strip above the keyboard to access the screws that hold it in place. You should be able to find a new keyboard on ebay relatively cheap. Good luck!
