hp dv6000 won't complete start up

[confused1111]

ok i turned off laptop went to bed got up 6 hours  went to turn on unit but all it would do is lights come on  cd-rom makes a noise, lights blink system turns off. sometimes it will just blink and turn off. but no matter which one it does, the cd-rom will make that noise  like when you do start up, and then sometimes it will light up cd-rom makes noise, opens cd tray and blinks then sturns off checked battery output is well within range, and am receiving power at the 120 volt connection, this unit has vista with latest service pack, 2gig max memory, and worked fine 6 hours earlier.   a non-computer tech just a wanna be said that it could be the power pack? if so how hard is it to replace. i have high mechanical abilities and have built several desktop computers from scratch. please help as i need it for my business and ebay sales. thank you jay

I had a similar problem with mine when it would not come out of hibernation mode properly. My solution was to remove the battery and start it using only the ac power cord. It started fine and has been running without problems ever since. I have no idea why this worked, but it did. The machine is now running quite normally with both the battery installed and power cord attached, or on either alone.

This week my dv6000 also crashed and has identical symptoms to yours.  Removing the power and starting up fresh has no effect. 

I would really like to know whether these sysptoms point to a fried mother board, bad drive, etc...  I suspect it's not the drive because it never even gets to the point where it loads bios. 

This is my second HP to crash in three months and I'm beginning to wonder what's up with the quality.  My shiny new Pavilion is also dead in the water.  It has a Seagate Barracuda with the infamous faulty firmware that locks drives in a busy state and Seagate won't unsuspend my drive because it's in an OEM PC.

I am having the exact same issue. Will starting the computer without the power pack be a good thing to do?

Sounds like a faulty mainboard.  I have a DV9520tx thats now a brick.

Basically if you have warranty get it fixed and sell it, if not then you have a cool drink coaster and need to find a decent manufacturer like I am doing.

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....

Nice guide! jdpanchal just posted his success story using it:

Reflowing graphic chip has become so common there are hundreds of videos on You Tube showing different procedures.....though I do not recommend the pen torch._Heat gun mentioned in some videos and by 'TheLaptopXpert' above is much safer for a novice!
