In the following guide I will disassemble a HP Compaq 8510p notebook PC and remove all main parts. According with the HP specifications, my disassembly guide should work for a HP Compaq 8510w mobile workstation. If it works for any other model, I would appreciate if you mention the model name in the following comments.
In the next guide I’ll explain how to remove and replace the screen inverter.
Before you start, you should turn off the laptop and unplug the power adapter.
STEP 1
Remove the battery.
Remove the hard drive and memory covers.
STEP 2
Remove the memory module.
Remove the hard drive as it shown on the sticker. Simply remove one screw securing the hard drive, slide the hard drive to the left and remove it from the laptop.
STEP 3
Remove one screw securing the optical drive (CD/DVD drive). Push the drive from the laptop with a screwdriver. Remove the drive.
STEP 4
Loosen two screws securing the keyboard. Both screws will stay attached to the laptop bottom.
STEP 5
Slide four latches securing the keyboard to the direction pointed by red arrows.
STEP 6
Lift up the keyboard with a sharp object, you can use a small flathead screwdriver.
STEP 7
Continue removing the keyboard. Place it upside down on the palm rest.
STEP 8
The keyboard is connected to the motherboard via two flat ribbon cables. Unlock both connectors by lifting the locking tab about 2-3 millimeters up with your finger nails. Be very careful with the connectors.
On the picture below you can see both connectors unlocked and keyboard cables removed. The locking tab must stay attached to the connector base.
STEP 9
Remove two screws securing the cooling fan. Unplug the fan cable from the motherboard.
Remove the fan.
STEP 10
Remove six screws securing the video card (VGA board) and processor (CPU) heat sinks.
Remove the heat sink.
STEP 11
Remove two screws securing the video card.
The video card will pop up at a 15-20 degree angle. Carefully pull the video card from the slot by the edges.
STEP 12
Now I’m going to remove the laptop top cover. Remove all screws from the bottom of the laptop. The orange screw securing the touch pad. There are two more screws (marked with green squares) hidden under rubber seals.
As you see, you can access the Bluetooth card through the hard drive compartment.
STEP 13
Lift up the touch pad assembly as it shown on the picture below. Place the touch pad upside down on the palm rest.
Disconnect the touch pad cable from the motherboard. Remove the touch pad.
STEP 14
Start removing the keyboard bezel with a small screwdriver. Do not forget to disconnect the cable the same way as you disconnected the keyboard cables.
Continue separating the keyboard bezel with your fingers and remove it from the laptop.
STEP 15
Unplug the LCD cable from the motherboard.
Unsnap three wireless card antenna cables from the wireless card.
Unroute the wireless card antenna cables.
Remove five screws securing the display hinges (two from the left hinge and three from the right hinge).
STEP 16
Remove four screws securing the display hinges on the back of the laptop.
STEP 17
Remove the LCD screen (display) assembly.
STEP 18
Remove six screws securing the top cover assembly.
Unplug the CMOS (RTC) battery cable from the motherboard.
Unplug the finger scanning device cable from the motherboard.
If you wish, you can remove the wireless card here. I’ll do it later.
STEP 19
Start removing the laptop top cover assembly. It could be a challenge.
The top cover is still attached to the bottom with a cable pointed with the red arrow. Unplug this cable. By the way, you can access the Bluetooth module from here too.
Remove the top cover assembly.
On the picture below you can see the finger scanning device attached to the top cover.
STEP 20
Remove two screws securing the speaker assembly to the motherboard (I don’t remember if I had to remove three screws).
Unplug the speaker cable.
Lift up and remove the speaker assembly.
STEP 21
Remove two screws securing the wireless card. Remove the wireless card from the motherboard.
Remove two screws securing the modem card. Unplug the modem card cable from the motherboard. Remove the modem card.
STEP 22
Remove two hex studs from the VGA port (two orange arrows on the top).
Unplug cables pointed with red arrows.
Remove five screws securing the motherboard.
STEP 23
Start removing the motherboard from the laptop base.
The motherboard has been removed. If you are replacing the motherboard, transfer the processor (CPU) to the new board.

hello… can you show me how to open motherboard for Compact Presario B19000
April 7th, 2009 at 10:37 pm
etia86,
What do you mean “to open motherboard”? Are you sure Presario B19000 is the right model name?

Theres 8510P models with a WWAN module. Even on those where theres no WWAN module the SIM-Card Slot exists on the left side under the original akku-pack but is just filled up with rubber.
Can you tell me if the WWAN module is just another Version of the wireless card or if the second connector for Mini-PCI Cards below the Trackpad (which is oviously not eqiped with a Mini-PCI Connector in the model you took your photos from) is assembeled on those machines and equiped with a HP un 24000?
just curious if it would be possible to upgrade those machines or if HP left away that connector intentionaly to stop people from upgrading to a WWAN capable Version of the machine.

In step 22 there is a cable at the bottom right of the laptop that has an orange sleeve on it, I have taken my pc apart but can not find where this plugs into on the right end.
Do you know what this goes to?
Great site by the way. I was able to replace my motherboard easily…..well, until I came upon this cable.
July 7th, 2009 at 8:50 am
dee,
This cable plugs into the Bluethooth module. It’s possible that you have no Bluetooth module installed. Leave the cable unplugged.

Hey, thanks a lot for this useful guide!!!
I used it to change my hinges on my Compaq nx7400.
August 22nd, 2009 at 5:20 am
I love you man! Thanks for showing everything step by step. You are the man! I’ve been a little scared about touching and removing the video card, but you just showed me how to so I’m going to get a new and powerful video card.

This guide rocks I just used it to swap out the mobo on my 8510w. So nice to have my laptop back and this guide helped a lot.
September 12th, 2009 at 7:32 am
This is an awesome guide.
I’ve been having a problem with my 8510w that I hope you can help me with.
I stuck a memory stick duo adapter into the SD slot, thinking it would work. It not only didn’t read the memory stick, now it won’t read my SanDisk card that I use with my digital computer (and which used to work fine.) I’ve tested the SanDisk card itself, and it is ok. I’m concerned that I damaged the SD card reader when I pushed in the Memory Stick Duo Adapter. Is there a way of testing whether the card reader is damaged? If so, how do I replace it? Is it attached to the motherboard, meaning I have to replace the whole motherboard? Where could I buy a new motherboard?
Many thanks for your help.

Paul,
Apparently you’ve damaged pins inside the memory card reader.
Take a look inside the card reader under bright light. Can you see damaged/bent pins?
Unfortunately, in most laptops the card reader is soldered to the motherboard and cannot be replaced.
Instead of buying an expensive motherboard, you can buy an external USB card reader. When you want to access your card, simply plug the reader into the USB port and it’s ready!
I wouldn’t replace the motherboard because of that.

Where is the PLL clock generator chip located? Could you point it on the last image?
May be you know, what is the PLL chip exact name for the 8510p/w?
October 13th, 2009 at 2:52 pm
Replacement of A/C power jack –
Is it soldered on? Is that something you can replace without removing the motherboard? I’m still under warranty but sending the computer in for service is a pain.
Thanks.
By the way, this site is awesome.

Hi
I have a quick question,
I had a wxga 1680×1050 screen and it cracked. I purchased the wuga 1920×1200 screen cause i wanted teh upgrade. Now the cable from the screen to the inverter does not fit. it is too short…is there anything i can do? Do i need to buy a separate inverter to go up to 1920×1200? Any help would be appreciated.
Thanks

What an amazing site! I have a Gateway M-2626u laptop I got from HSN Dec. 08. The warranty expires next month. At that time I want to make some upgrades(i.e. 500GB HDD, Bluetooth module). My laptop didn’t come with bluetooth, although the manual mentions it was an option and there is a labeled keyboard shortcut to turn it off and on. Searching the Gateway site, I managed to find out that my M-26xx series support a Bluetooth 2.0 module and the drivers are for Broadcom module. Could you give me some guidance on the exact model # of the module I would need and how to install it?
November 7th, 2009 at 6:34 pm
David,
I cannot tell where to install the Bluetooth module. I’ve created a couple of different guide for a Gateway M-series laptops, you can find them in the Gateway Laptops category on the right side of the website, but I’ve never taken it apart completely.
November 7th, 2009 at 7:03 pm
Thanks for your prompt reply! Here’s what I’ve been able to dig up:
——————————–
GATEWAY M-2626u BLUETOOTH MODULE – BROADCOM BCM 92045
Part numbers for the card: BCM2045, BCM92045, 2528449R, 6008074R
Features include:
Fully supports the bluetooth 1.1, 1.2, and 2.0 standards. Including 1Mbps, 2Mbps, and 3Mbps EDR operation
Lowest current consumption in all modes of operation
Supports class 1, 2, and 3 designs
Automatic calibration and frequency detection of crystal frequency
PLEASE NOTE: Cable connecting the Bluetooth module to motherboard is not included.
——————————————–
If I find more info I’ll post it here. I just might get the nerve to try and install the module after my warranty expires. I’ll study your Gateway M-Series guides in the meantime. Thanks for providing this resource.

I need to replace a burnt component on the motherboard. I need to know the markings on the component. The component is a 8legged integrated circuit, located behind the plastic around the docking plug. It is marked with U606 on the board.

Hello I just found your site AND I LOVE IT!! Quick question for you tho! Can you install a bluetooth connetor on to a HP DV9000?
February 4th, 2010 at 6:49 am
