HP Pavilion dv6000 Won't turn on/Black ScreenSolved/Closed

Question

Hello,

This morning I turned on my laptop and worked perfectly... for a couple seconds. My HP pavilion Dv6000 froze and I decided to manually turn it on and back on. I pushed, and held the power button until it turned off. Once it turned off I decided to take the battery out (for no apparent reason). So I took it out and put it back it (i didn't really touch anything). Once I put it back in I tried turning it on by pressing the power button, but it wouldn't turn on. The screen is black, there are no blue lights that are on. (These lights are on when you turn the laptop on). 

I tried the taking out the battery and hold power button for 30-60secs trick, but no luck. I also have taken out my laptop's ram and re-inserted it (same with my hard drive). Oh and my battery is fully charged. I tried searching the net for solutions but no one really has the same problem as me. Most of the other people with problems said they could hear the fan, but with mine there is noting. No sound. No lights. No working laptop just one really expensive door stop.


HELP!

After reviewing the applicable DV6000 threads for this issue across the web I've come up with this remedy which seems to work if you are disinclined to perform the "real" fix of reflowing the solder joints of the NVidia chip on the motherboard.

1. Press the on button of your offending DV6000.  The blue LED next to your SD-MS/Pro-MMC-XD slot (left side front) should stay lit during BIOS and the screen is blank.  You may also notice the LEDs around the network port (8 pin modular connector) flash at initial power on also.  This is the state my system gets into and seems to be the common state referred to by other users having the problem.
2. Allow the system to go through the automatic "restart" that occurs when you are in this state.  The system will auto-restart repeatedly is another symptom of this problem that seems to be fixed by this procedure.
3. Once the system has auto-restarted once, press and hold the power button until the all the LEDs go dark and you hear the disk drive make a short whirring sound following by a clunk.  If your system shuts down quietly, you will need to return to step 1 because this whir-clunk sound indicates you have crashed the BIOS and that is needed to get the right state for the next step.
4. After crashing the BIOS in step 3, press and *hold* the escape key (labeled esc) immediately below the power button and press the power button to turn on the system again.  If you are successful the blue LED on the side will briefly light (1/2 secs I'd estimate) then go out and about 5 seconds later you will see the BIOS messages on the display and the system will continue to boot with the display active.  The amount of time you wait between crash and restart may be important so I try and do this step within 1 to 2 seconds after I've completed step 3.

I always shutdown my system instead of simply putting it into hibernation or sleep.  I do this because I don't want the crashing of the BIOS to cause corruption on the hard disk which is quite possible given a MS operating system.

hi,

try to connect the charger and see if the light goes on.

if yes, then try to switch it on.

or else you should leave it for repair at a repair centre.

Try to reset the Systemboard. You need to remove the system board to reset it.. Its not easy. It would take 30 minutes if you are familier with removal of systemboard. What I think is , your system board is gone. It may cost you around 200-250$. Its not worth spending 250$ on it.. Many dv6000 had system board issue. 
If it is under warranty, please send it for repair. If its not under warranty, Buy a new laptop(not HP this time :-)) and  remove the HDD from your old Laptop and put in 2.5" External enclosure to use your data in your HDD

HOW TO FIX YOUR DV6000/DV9000/DV2000

All the Problems described in the previous posts are Graphics Related..
Faulty Nvidia Chip..Both Intel And AMD Based Motherboards..Though More Common on the AMD..

The symptoms of the Laptop Powering on and Shutting Off Repeatedly..Or.. Powering On and Having No Video...Or... Power Strip Lights Up, Beeps,Shuts Down...Or..No Power At All...Or.. Intermittant Loss Of Wireless/Video Goes In And Out/Touchpad Slows and Freezes..

To Fix this issue, You will need to Reflow The Graphics Chip.

I will Explain In Full Detail As To The Correct Method Below....

HP DV6000/DV2000/DV9000 Compaq v2000 Video Chip Reflow Instructions 

First Step Is Complete Disassembly Of All Parts And Components..
Remove RAM, Remove CPU, Of Course Remove Heatsink and Fan assembly.

Next Step is Insulating the Motherboard... You need to Protect The CPU area, The RAM area, Cover any plastic Plug ports.

Try to leave 1/4 inch area around the edge of the chip free of insulation.

To Insulate the Board.. I use thick pieces of Tin/Aluminum, you can fold up some aluminum foil (tin foil) About 4 folds thickness....

Now that you have your Motherboard Insulated... Make Sure There's Nothing Flamable Or Burnable Below the Motherboard... it will get quite hot underneath.

You will need a Heat Gun.. You can get one of these at your Local Home Improvement Store, they cost about $15 - $30.. You Will Use ONLY the LOW Heat Setting... I REPEAT..... USE ONLY THE LOW HEAT SETTING ....

Next You Will Need Some Coins.. Yes Coins.. 
8 Quarters and 2 Nickels... Put the 2 Nickels On the Bottom and Stack Quarters On Top...
Place The Stack Of 2 Nickels And 8 Quarters On Top Of The Graphics Chip...

The Reason for using the Coins: Using the coins serves a few purposes...
1) It Helps Transfers the heat Into The Chip More Evenly/Slowly
2) It Helps Hold The Heat Longer/Then Helps To Cool Slower
3) It Gives The Correct Amount Of Weight That Is Needed To Press The Chip


A Thing To Look Out For...

Hewlett Packard is nutorious for using the RED epoxy around the edge of the Graphics chip.. this epoxy is used to help secure the chip to the motherboard...
This is a process that is Hand Done at the Factory.. And Some Boards Will Have Only A Little Amount of this, Some Will Have Alot of it...And Some are Only Done On The Corner Edges....

If There Is Alot of This On Your Chip, You Might End Up Needing To Carefully (REAL CAREFULLY) Remove as much of this epoxy as able to....You can use a Razor Blade To Lightly Scrape This Off... DO NOT MISS AND SCRATCH THE MOTHERBOARD!!! Go SLOW...

Now Comes The Heating Of The Chip...

Start With The Heat Gun About 6 Inches Away From The Top Of The Quarter Stack..You want to be holding the gun at a 45% angle.. Aim the heat at the Edge of the chip, You Will Start Rotating Around the Chip- around the outer edge of the chip...then use tighter circles concentrating on the quarter stack, then after about 30-40 seconds, slowly move closer to the chip...
Never Move the Heat Gun Closer than the Top Of Your Coin Stack...Then Pull It Back And Slowly Repeat.. The Chip Needs To Get Hot Enough To Re-Melt The Solder Balls On The Underside Of The Graphics Chip Back Down To The Contact Pads On the Motherboard.. and this takes Quite Alot of heating to Do.... You Must Not OVERHEAT the CHip... It Is Best To Underheat it and have to Redo.. than to overheat.. It will cause the solder to break down and even crack/split.. causing failure forever...
This process will take about 3 minutes total.. Once you shut off the Heat Gun.. Leave The Stack of Coins On The Chip And Let Sit For Another 5 minutes..

Now Remove The Coins(carefull they might still be hot)
Remove All Insulation.. Reinstall RAM, CPU, Heatsink and FAN Assembly (and Of Course Thermal Pads or Paste.. Note:. If Paste Is Used.. It Must Be Silver Paste... 

Now You Can Connect The Power Button Strip/ Video Cable And The DC Jack Cable.... And Plug In AC adapter .. You're Now Ready To Test For Solid Power and Video....

Hi,

I had this, or a similar problem, and spoke to a HP tech guy who helped fix it over the phone. My machine is an HP DV6000. The problem showed up as a blank black screen, with no sign of booting up or power.

The problem is apparently caused by a build up of static - I think thats what I was told.

The solution which works for me is:

Remove the battery and unplug from mains. Then hold the power button down for 30 seconds. Re-connect to battery and power supply and the machine should work.

It isn't the mother board. If you open up the keyboard, you will see two ZIF cables connected to the circuit around the power button. The problem is that those cords go bad. All you have to do to fix it is to exchange the cable that goes to the power button with a new one. It is a very simple fix.

Ok I wanted to post my story here, cause this came up in my research on this issue. This just happened to one of my lady friends literally three days ago. Based on this link:

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us.&docname=c01087277#c01087277_identify

she had one of the machines that was affected by this issue. Problem is, she bought this laptop in 2006! She doesnt know a lick about computers, so she let me handle it. Seeing how I saw so many of you guys getting told to pay to fix the issue, I tried another means to get support. I used their online chat system for tech support. I kept the description brief: blank screen on startup, and once he ackknowleged and verified her information, I told him that a friend (which was me!!) found the link listed above. He acknowledged the link, but wanted to do some further troubleshooting. 

About 15 minutes of fake troubleshooting on my part, he wanted me take the hard drive apart, and try to boot to see if I can at least get the bios ?!!?!?!?!?!?!? And he sent me a link to a video on how to do it lol! Keep in mind, he is under the impression that I am some lady with no computer skills... So I told him that I didnt feel comfortable taking apart the computer and he didn't push back, acknowledging that there was an issue with the video card on the motherboard, and that it needed to be fixed. He then brought up the link I sent him earlier, and said that the laptop was covered under that limited warranty until March 2009. Seeing that I was anticipating that he was gonna tell me to pay for a fix, I immediately replied when did HP send an email to notify me of this issue. Since I had her register her email when she bought it, I knew it was on file. I also told him that I didn't think it was fair that I am not being covered for something that I could not have prevented. He paused for a minute or two, and then replied to not worry, that because this laptop was still under warranty, he will create a ticket to get it fixed free!!! LMAO  I about fell out of my chair laughing so hard, cause I knew he was telling me a boldface lie about the warranty. But since he did...I pressed him some more about the warranty after we were done, and got him to document that the laptop was still under the original warranty for another 90 days!!!!  Gotta love outsourcing liars!!!! LOL

So here are somethings I would suggest trying:

1. Make sure your laptop is registered with your email address. You can use that angle about them not notifying you if they try to charge you.

2. Let them troubleshoot!!! Being a technician, I know that the easiest way to get a company to eat the cost without a whole bunch of grief coming back at you is to provide a substantial amount of documentation. If they show that they did everything they could to try to get you back up and running, their superiors wont even raise an eyebrow about it. You don't have to actually do the troubleshoot, but you can "act" like it for sure!! Just let them try to exhaust all avenues, and once they believe that it is a defect, they wont push back so hard when you complete the troubleshooting.

3. Try online chat! The cool thing with that is, the agent isn't under the same pressures to resolve the issue like it would be over the phone. The have time to research, ask, get approval without getting their nerves up. And on the flipside, you won't get so angry cause you are getting tired of them telling you to do things when you know they wont work. When they ask you to do something, say ok but go get a drink or flip the channel. You see, they cannot disconnect the chat like they could the phone! Every conversation is logged, and it shows who ended the chat. Plus that gets you some written documentation on what they did or say if things go awry so you would have some sound evidence. 


Hopefully this helps you guys get your machine fixed. And if all else fails and you need a smooth, jive talker to get your stuff repaired give me a buzz (for a nominal fee of course lol)!!!

Here is the solution which worked for me:
1) Switch on the laptop
2) Cover the laptop with blanket completely and keep the laptop under blanket for around 30-45 mins
3) Remove the blanket and your laptop will start working miraculously!!!

The above solution worked for me

PS: This is a temporary solution but whenever your laptop shows the blank screen, you can employ the above method and your laptop will start working.
I feel it is a better method rather than spending $300-$400 for repairing your laptop

Please try and let me know the results
