In the following guide I explain how to disassemble HP Pavilion dv6500, dv6600, dv6700, dv6800 notebooks. In this particular case I’m taking apart an HP Pavilion dv6700 notebook.
I believe this guide will work for some other models in the Pavilion dv6000 line.
You can use these instructions for removing and replacing all main notebook components.
If you need spare parts for HP Pavilion dv6500/dv6600/dv6700/dv6800 notebooks, you can search here.
Turn off the notebook and unplug the AC adapter.
STEP 1.
Remove the battery.
Remove four screws securing the hard drive and memory (RAM) covers. Remove both covers.
STEP 2.
Lift up the right side of the hard drive assembly to disconnect it from the motherboard.
Remove the hard drive assembly.
STEP 3.
Remove both memory (RAM) modules.
Disconnect two antenna cables (black and gray) from the wireless card. Remove two screws securing the wireless card to the motherboard. Remove the wireless card.
By the way, in this step you can access the CMOS (RTC) battery.
STEP 4.
Remove one screw securing the CD/DVD drive to the laptop base.
Pull the CD/DVD drive from the notebook and remove it.
STEP 5.
Remove all screws from the bottom of the notebook.
Do not forget:
- three screws in the CD/DVD drive bay (yellow).
- one screw in the hard drive bay (green).
- two hex studs under memory slots (orange).
Mark all removed screws somehow so you don’t forget their location when assemble the notebook back together.
STEP 6.
Carefully lift up the right side of the power button board cover.
There are two cables connected to the motherboard. We’ll disconnect these cables after removing the keyboard in the STEP 8.
STEP 7.
Now, when the power button board cover separated from the laptop case, you can remove the keyboard as it shown on the picture below.
STEP 8.
Carefully disconnect the keyboard cable from the motherboard.
For more detailed keyboard removal instructions please follow this guide for HP Pavilion dv6000 laptop.
These instructions should be identical for HP Pavilion dv6500, dv6600, dv6700, dv6800 notebooks.
STEP 9.
Disconnect two cables running from the power button boar cover.
There are no locks on these connectors. Simply pull both cables from connectors.
STEP 10.
Turn the cover upside down and disconnect one cable from the power button board.
STEP 11.
Remove the cover.
STEP 12.
Disconnect the video cable connector from the motherboard.
This connector is located close to the left display hinge.
STEP 13.
Pull both wireless card antenna cables through the opening in the top cover. Unroute both antenna cables.
Remove two screws securing the display assembly hinges.
STEP 14.
Lift up and separate the display assembly from the notebook base.
In one of the previous posts I explain how to disassemble the display assemble and remove the LCD screen from an HP Pavilion dv6000.
These instructions should be identical for HP Pavilion dv6500, dv6600, dv6700, dv6800 notebooks.
STEP 15.
Remove five screws securing the top cover assembly.
Disconnect the touch pad cable from the motherboard.
STEP 16.
Start separating the plastic cover from the notebook base. You can use a piece of soft plastic (I’m using a guitar pick) to separate the cover from the base.
The cover has been removed.
STEP 17.
Separate the top cover assembly from the notebook base.
Again, as a case cracker I’m using the same guitar pick.
STEP 18.
Remove the top cover assembly.
The top cover assembly has been removed.
STEP 19.
Disconnect the Bluetooth module cable from the motherboard.
Remove two screws securing the Bluetooth module.
Remove the module.
STEP 20.
Remove four screws securing the express card slot.
Slide the slot board to the right and disconnect it from the motherboard.
STEP 21.
There is only one screws securing the motherboard to the notebook base.
Remove these screw.
STEP 22.
Start removing the motherboard as it shown on the picture below.
When the motherboard is lifted up, disconnect one cable from the audio board.
There are two more cables connected to the motherboard and we’ll remove them in the next step.
STEP 23.
Turn the motherboard upside down and disconnect two more cables.
STEP 24.
The motherboard has been removed.
The audio board and power connector board are still connected to the notebook base.
STEP 25.
Loosen four screws securing the cooling assembly (heat sink and fan) to the motherboard.
STEP 26.
Lift up and remove the cooling assembly.
Now you can access the processor (CPU).
In this model the power connector (DC power jack) is not soldered directly to the motherboard.
The power connector is mounted on a separate board.
If the power connector fails, you can desolder it from the board and replace with a new one or replace the entire power connector board.

hey there!
Thanks a lot for this awesome HowTo!
I have a similar problem with a HP Pavilion dv6545eg:
Some weeks ago the original power supply broke with a loud pop and bad smell.
i got a replacement PSU by acompany called “hama” which is supposed to suit for this model (19.5V, 4.72A). It worked fine until two days ago, when the battery went out – Windows shut down. And the notebook could not be turned on again since.
When pressing the Start-Button NOTHING happens – no screen, no fan-noise.
As long as the battery is attached to the notebook, the blue LED at the front blinks 3 times when pressing the Start-Button. Nothing else. (If i interprete this right, this indicates an empty battery).
When the power supply is attached, the blue Power-LED (ring) at the Power-input is on. Still nothing happens when pressing the power button.
If both is battery and PSU are attached, it doesn’t seem that the battery is being charged. I’m not sure though – but the LED at the front doesn’t indicate the charging, all LEDs besides the one at the power input are off. still the Battery-LED blinks again 3 times when the battery is attached.
I followed your steps to disassamble the notebook, because i thought it might be a bad soulder-spot around the power-input or a broken lead to the mainboard.
but i do find 19.5V at the mainboard – power input-spot (next to PR9, PR10).
is there supposed to be any voltage at the battery-pins, when the battery is disconnected? i couldn’t find any – maybe there’s the problem?
soulder-spots look fine tough, and i can’t really figure out the schematics – i guess the charging voltage is dependend on electronics on the mainboard and the battery-pack itself.
Any suggestions furthermore?
I wonder if the notebook would work with a full charged battery… just don’t know how to get my battery charged without the notebook working…
Don’t really want to spend €400,- for HP repair, rather buy a new notebook.. but with what money?

I did the same thing with the Bios, flashed it & the error stopped. Computer came up & ran beautifully, for about a month. Now it’s right back were it was with the replacement motherboard??? Will not start up again, just recycles through the initial procedure only. This is ridiculous, I guess the motherboard I bought must have been a used one (did not buy from HP) I’m going to try one more but if that does the same thing I’m trashing this piece of crap laptop.
April 10th, 2010 at 10:57 am
Just thought I’d post back with results for the good of all. I flashed the BIOS to the latest version using WinFlash (holding my breath the entire time), and now I no longer get any complaints from the BIOS about the wireless adapter.
Installing Win7 now….
April 9th, 2010 at 9:46 pm
I recently replaced my motherboard with a refurb from an Ebay retailer. Double and triple checked the HP documentation and my old motherboard’s serial #’s to make sure I was getting the right one.
Well, everything starts fine, but I also get the 104 Error. Unsupported wireless network device detected. It pulls a total system halt at this point until I remove the adapter.
Seems there might have been different revisions of the board released. I hope with all my might that a BIOS flash will do the trick. Sad thing is, that’s how the last board fried
Anyone know which chip on the board is the BIOS chip, in case it fries again?

Kol,
Here’s how I fixed “no video” problem on a Comapq Presario V6000 notebook:
http://www.laptoprepair101.com/laptop/2010/04/06/fixing-compaq-presario-v6000-motherboard-no-video-issue/
I’m still testing the laptop to find out for how long this repair will last.
April 7th, 2010 at 5:03 am
Thanks for the helpful guide. I used this to strip down a friends HP DV-6552ea Pavilion laptop.
His laptop had suffered the famous no display problem that can only be solved by either heating the nvidia chip up or replacing the motherboard. I tried to heat it up and took all the precautions whilst doing so, but the laptop failed to turn on afterwards which shows the important of using a thermometer of some sort to gage the temperature whilst your working.
There was a thermal pad in between the heatsink and the nVidia chip – and it still overheated. I removed this pad and air-dusted the entire inside of the laptop. I then noted that the heatsink does not sit flush with the nvidia chip, and therefore used a British one pence piece (with some thermal paste either side of it) and placed this on top of the nvidia chip. I cleaned up the dried up paste on the CPU/heatsink and applied fresh to it. My original intention was to get a small square piece of copper which i did, but the depth was wrong. I think it needs to be atleast 1.5/2mm. After replacing the motherboard, the cpu temp is now 26º/32º (core #0 and #1) and the Nvidia chip is at 56º steady which is fine.
April 5th, 2010 at 1:49 am
Nope. They applied a pad to what I assume is the chipset (sits between the CPU and GPU chips anyway), but the only thing that stood between the GPU and cooler surface was air.
April 4th, 2010 at 10:06 am
DK,
Maybe you didn’t have any grease applied to the VGA chip because instead of thermal grease HP uses thermal pads?
April 4th, 2010 at 4:55 am
Thanks for the guide. Helped a lot! It’s a real shame you have take your whole laptop apart just to clean and grease the cooling component.
Mine (dv6970ej) didn’t have thermal grease applied to the VGA either, just as Producr mentioned.

Thanks to the author for such thorough explanation!
I should mention that my pavillion dv6600 has lost sound both from speakers and from audio-out.
Kobus may just have the same trouble – dead audio.
As for me, I use usb audio card instead.
March 15th, 2010 at 2:36 pm
Hi,
I have a dv6174ea. The system clock is not running, just runs from 10-11pm then goes back to 10 again.
I opened up the panel to replace the battery but instead of a silver button battery it had a black connecter attached to it with red and black leads coming out of it. what is this thing?
I’ve had my motherboard replaced a few times.
Cheers.
March 6th, 2010 at 11:38 am
Guess I should have mentioned, its an HP DV6436nr, I’m thinking the motherboard is not compatible with the wireless card or vice versa….
March 6th, 2010 at 11:27 am
I just got done replacing the motherboard following your guide, when I hit start she came right up or at least I thought. I’m getting an error now on start-up that reads “104-Unsupported wireless network device detected. System Halted. Remove device & restart”
I have no idea what it’s talking about, there’s nothing in the drive. Ever heard of this or know what to check?
March 5th, 2010 at 11:37 pm
Well, I just spent an afternoon preparing my kitchen counter as an operatory, procuring the blow torch with which to use as the prime instrument and began disassembling as shown above. The aim is to reflow the video chipset on the dv6000 motherboard. Hopefully the result will be a fully functioning computer when the procedure is completed.
The motherboard is now removed and shielded with foil to isolate the loose chip and protect the surrounding components from the heat. I now train the torch on the chip and slowly heat it up to the required temperature of 210 degrees to remelt all the solder underneath it. I use an inexpensive infrared thermometer to monitor the progress. Once reaching the critical temperature, I shut off the torch and let it cool. I reassemble the computer using the directions above in reverse and Whammo! a fully functioning computer! Thank you for this post, a $10 fix for a $400 problem. for additional info on reflowing the video chip go here…

Henry,
Video failure is a known issue with dv6000 series.
First, I would try reseating memory modules. If you have two modules, try removing them one by one.
If the laptop still has no video even when only one (either one) memory module is installed, probably this is the video chip failure.
HP knows about this problem and you can get a free repair from HP if your laptop qualify.

I have a hp dv6245 lap top. When I was using it the other day it powered off and would not come back on. I attached the the power cord to it and plugged it to the outlet, the blue light at connection at the lap top came on but noting would come on. When I pressed on the power button board cover, (Altec Lansing label area) that section would light up but would not do anything else when pressure was put on the power button board cover. Is it possible that there is a wire loose. I took the lap top to the Geek squad, they said it was probably the motherboard. Is this true.

bautz,
I believe this model fails because the video chip separates from the motherboard. I think Chris did the trick in order to re-flow the video chip.
There are many different DIY-tutorials for fixing video problems in HP Pavilion dv2000, dv6000, dv9000 series notebooks.
Here’s one of them:

Not sure if it works, never tried it myself. Proceed on your own risk.
February 28th, 2010 at 1:23 am
@Chris (comment 40)
How did you fix your nvidia problem?
I think I have a similar problem, but I have a HP dv6366ea.
Can you link me a guide or how to to solve that?
Removing the hard drive, starting the pc in a towel and let it run for 1 hour it’s enought to solve?
Thanks
February 27th, 2010 at 9:55 pm
Chris,
I guess you should have used this guide for HP Pavilion dv2000 series.

Brilliant guide, a few days ago my HP DV2630EA died with the infamous nVidia chipset problems on the G84 and G86 – graphics corruption, even in the BIOS – making the laptop useless.
After using the towel trick (wrap the laptop in a towel, turn on minus hard drive, leave for one hour to allow system to get VERY hot – hot enough to remelt solder on graphics core and fix problem), I dismantled my laptop using your guide to replace the default thermal pad on the graphics chip with a copper spacer (from eBay) and some AS5.
I have now put the laptop back together and she’s now doing just fine. Thanks for the guide, even if the design of my laptop is slightly different to the one shown above.
Cheers!

I never took out the cpu from its socket but I’ll chk again….also, I didn’t take away any heat sinks…but the one on top of cpu is completely gone anyway. I already reseated both RAM chips but to no avail….
February 25th, 2010 at 2:21 pm
Sol,
Did you remove the heat sink for cleaning? Maybe you accidentally pulled the CPU from the socket. If that’s the case, you’ll have to reseat the CPU.
Also, check memory modules. Maybe one of them is not connected correctly. Try reseating both memory modules.
February 25th, 2010 at 1:34 pm
Hi,
I have dv6600. Yesterday I disassembled it to clean the fan. When I put it all back together and turned it on, the display would not power up…and the system seems to be powering up but all processing stops withing the first 3 seconds as the hard disk light stops blinking.
If display cable is not hooked up properly, can it stop the system from loading the operating system? I already checked all the cable connections and they seems ok…Could anyone help? What else should I check?
February 24th, 2010 at 12:24 pm
Thank you for the fast answer.
I checked with an external monitor, but it doesn’t work, it stays black (once upon a time it worked), and the laptop screen boot up flickering.
It’s like the video card output doesn’t work.
I’ve found googling that dv6000 laptops suffer of the video card chip detaching from the motherboard. I hope to solve.
Anyway, I’ll test the ram modules.
February 24th, 2010 at 11:53 am
bautz,
It looks like the video card failure. Unfortunately, the video card is integrated into the motherboard and the whole motherboard has to be replaced.
Just in case, test your laptop with video on the external monitor. Can you get any image at all? Is it garbled too?
Also, try removing memory modules one by one. Test the laptop with each module individually. I doubt it will change anything, but try anyway.
February 24th, 2010 at 11:48 am
Hi, nice guide!
I have an HP dv6630, and 2 days ago stopped working.
It seems like a video card issue.
The monitor show a lot of artifacts, strange numbers and letters, also on the bios screens.
I post you a photo of the Boot menu (pressing esc at the very beginning of the boot, so I can take a photo):
http://www.postimage.org/image.php?v=aVrJJcJ
(it’s possible to read “Boot Menu” at the center of the screen)
What could it be? Could the video card be broken or whatelse?
I have to try to open my laptop?
Thank you in advance
February 23rd, 2010 at 9:49 pm
Thanks for the effort but my sound still doesnt work.
I checked all caples in the steps above and everything looks fine.
I think it might be a software or windows problem.
Thanks anyway

Kobus,
It’s kinda strange. In the service manual the speaker assembly in a Pavilion dv6000 is shown as a separate module but according to my pictures it’s attached to the cover above the keyboard. It’s confusing.
Make sure both cables shown in the step 9 are connected to the motherboard.
Also, check all cables shown in the step 10 (not just one pointed by the yellow arrow). Make sure all cables are properly connected.
February 19th, 2010 at 10:08 am
Kobus,
Not sure about that.
I think that sound chip is integrated into the motherboard and technically this board shouldn’t affect external speakers, but I’m not positive 100%.
I just looked at the official service manual for dv6000. Maybe you forgot to plug the speakers?
Take a look here:
http://h10032.www1.hp.com/ctg/Manual/c01035677.pdf
It’s on the page 5-30.
