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.

Could you please tell me where is LCD backlight power supply? I guess not in LCD connector where those thin wires are? Problem is that my computer was spilled with water on back side when off and now when I turn it on I see the picture but totally dimmed.
And sometimes LCD is normal for few moments, co I think it is something wrong with contact.

@ HASNAIN,
If you cannot remove the broken piece form the DC jack and it stuck permanently, it’s necessary to replace the DC jack.
In order to replace the jack you’ll have to buy a new DC jack, remove motherboard from the notebook, and replace the DC jack.

I have this computer and will not start, I’m trying to repair the motherboard, but I find the faulty component.
I changed the power connector and nothing.
What could be the problem?

Hello,
I have checked every where to find speakers in side the lapy i have no idea where are the speakers?
Thank you in advance.

Bradley,
You are correct. The whole laptop disassembly required, there is no easier way.
Here are DC jack replacement instructions.
June 2nd, 2012 at 9:09 am
Thank you VERY much for this instruction. I’m worried that I already know the answer to my question but it never hurts to ask.
I’m reasonably certain, after testing the adapter cord and plug that the short I have (intermittant reminders that I’m on battery power) is a disconnected solder pad on the pcb mounted DC power receptacle.
Reading the downloadable service manual and following your tutorial above, it appears as if this part of the board is inaccessible without an almost complete tear down of the computer. Is this true? Is there any easier way to get to this point on the board?
Thanks again for the tutorial.
