Re: HP pavillon dv6000 boot troubleshooting !
The HP's had faulty graphics video cards made by Nvidia. This is a known issue that you will see documented all over the internet. The guys at http://www.generalsystemsconsulting.com fixed mine at a reasonable price $125.00 includes return shipping back to me.

Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help: Possible causes:
1. AC adapter failure. 2. Power jack failure. 3. Motherboard failure.
Possible troubleshooting steps and repair solutions: 1. Test HP EliteBook 6930p charger with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.
2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.
Your Pavilion DV6000 laptop is the key to your productivity, which is why it is essential that it turns on when you need it. The DV6000 is lighter than comparable models from other brands, and has a large, sharp display. While it has plenty of processing power, the DV6000 can have normal boot problems as well as problems caused by faulty battery packs that were installed in some units. Attempt to troubleshoot the laptop and find out if the laptop is eligible for a new battery pack.
1.Hard reset your laptop if there is no life at all. Unplug all peripheral devices and remove the battery. Unplug the AC cable and press and hold the power button for at least 15 seconds to drain all power. Reconnect the AC cable and hit the power button. 2.Verify that the battery pack is on the recall list if the laptop powers up without it. Fill out the form on the battery pack recall website (http://bpr.hpordercenter.com/hbpr/). You will have to input the serial number of the battery pack as well as a location to ship the replacement battery if you are eligible. 3.Hold the AC cable where it plugs into the laptop and wiggle it while hitting the power button one time. LEDs that come on and off intermittently indicate a faulty power cable. Order a replacement power cable through HP or a third-party vendor. 4.Write down any visual or audio error codes such as LEDs blinking or unusual beeping. The error sequence will be helpful when talking to an HP support person.
1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced. 2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop. 3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced. 4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work. 5. The power button could be bad. 6. The motherboard could be defective & needs to be replaced.
There is a good possibility that the DC jack in the laptop has failed or has become dislodged from the motherboard. I would lean toward a failure of the jack personally. I have replaced countless numbers of these and they are relatively easy to change out, but you have to strip the laptop down to the motherboard. Reguardless of whether the jack is good or not, it will still light up the led that is integrated into its bezel, but the jack itself will not transmit the power to the board. They can be purchased on Ebay for around 20 bucks. Below is a link to the service manual for the DV6000 for disassembly reference.
Faulty Nvidia Chip....Yes, Overheating of the Graphics Chip will result in the dv6000 not powering on..
Though You should check through power to the DC Jack...
Does the DC Jack Show its Blue Connection Light When AC Adapter is plugged in?? If so, then again, you have a failing video/GPU chip.. A reflow to the chip will fix your issue..
Some years ago I had a similar issue with an IBM and with that one the capacitor that filters out the current (right after the power jack, usually the very first capacitor that gets the power) was short circuited. It was a ceramical capacitor, at least that's how we call them here.
Explain, (endured a hit). Electrical or physical? For the hard drive (a clicking sound means a spindle problem). Suggest you get a new drive if it's no longer under warranty. Once you install a new drive you can slave your old bad drive into the system & pull your data off it before it stops working.
