In this guide I explain how to disassemble an HP Pavilion dv7 notebook.

To be precise, I’m taking apart an HP Pavilion dv7t-1000 notebook but you

line.

The guide will show how to access both memory modules and hard drives if

you are upgrading the notebook, remove most internal components, access

and clean the cooling fan.

Before you start, turn off the notebook and remove the battery.

Static electricity can kill your laptop. I

recommend wearing an anti-static wrist

strap while working with internal parts of

your laptop.

STEP 4.

Remove one screw securing the CD/DVD drive.

Slide the CD/DVD drive to the left to disconnect it from the motherboard.

Remove the CD/DVD drive.

STEP 5.

Remove all marked screws from the bottom of the notebook.

The green circled screw secures the keyboard.

Don’t forget to remove two screws hidden in the CD/DVD drive bay.

STEP 6.

Start separating the speaker cover from the notebook base.

You can use a guitar pick as a case cracker. Insert the guitar pick between

the speaker cover and case and slowly move along the side.

STEP 7.

Lift up the speaker cover. Be careful, it’s still connected to the motherboard.

In order to remove the cable, you’ll have to unlock the connector first.

Move the brown clip about 2 millimeters in the direction shown by two

arrows. The clip must stay attached to the connector base.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv7-notebook/ Page 4 / 16

On the picture below the connector is shown in the unlocked position.

STEP 8.

Now you can remove the speaker cover.

STEP 9.

Remove four screw securing the keyboard.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv7-notebook/ Page 5 / 16

STEP 10.

Lift up the keyboard from the base and access the cable connector

underneath.

STEP 11.

Carefully unlock the keyboard cable connector.

Move the brown clip about 2 millimeters in the direction shown by two

arrows. The brown clip must stay attached to the connector base.

If you damage the connector, the keyboard will not work when you assemble

the notebook back together.

Well… I broke the connector. I removed thousands of laptop keyboards

before but I broke this connector!

As you see, the left pin on the brown clip is missing.

No panic! I still can use this clip to lock the connector.

motherboard.

STEP 12.

Pull Wi-Fi antenna cables though the opening in the cover.

Remove three screws securing the speaker assembly.

Disconnect the speaker cable (green arrow) from the motherboard.

STEP 13.

Remove the speaker assembly.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv7-notebook/ Page 7 / 16

STEP 14.

Disconnect the video cable from the connector on the motherboard.

Remove six screws securing display hinges (three screws per hinge).

STEP 15.

Separate the display assembly from the notebook base.

In the next post I will explain how to take apart the display panel assembly

and remove the LCD screen with inverter board.

By the way, it’s not necessary to separate the display panel assemble from

the base in order to take it apart.

STEP 16.

Disconnect and remove the CMOS battery.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv7-notebook/ Page 8 / 16

Remove all marked screws from the bottom. The green circled screw is

hidden in the CD/DVD drive bay.

STEP 17.

Remove all screws securing the top cover assembly.

Disconnect the touch pad cable from the motherboard.

STEP 18.

Start separating the top cover assemble from the notebook base.

You can use same trick with the guitar pick shown in the step 6.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv7-notebook/ Page 9 / 16

STEP 19.

Remove the top cover assembly.

Here’s the back side of the top cover assembly.

STEP 20.

Disconnect the USB and audio board cables from the motherboard (green

arrows).

Disconnect the cooling fan cable from the motherboard (yellow arrow).

Remove four screws securing the motherboard.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv7-notebook/ Page 10 / 16

STEP 21.

Lift up the right side of the motherboard as it shown on the picture below

and disconnect the DC-IN jack cable.

STEP 22.

Remove the motherboard from the notebook base.

On the opposite side of the motherboard you can access the processor

(CPU) when the heat sink is removed.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv7-notebook/ Page 11 / 16

By the way, the best way to find a replacement motherboard is searching by

the HP part number. The part number should be located on a sticker in the

memory compartment. The HP part number looks like XXXXXX-001.

Here’s the notebook base without motherboard.

The USB board, audio board, cooling fan and DC-IN jack are mounted on the

base.

The DC jack attached to a harness. New jack harness for dv7 notebooks

available here.

In order to remove the cooling fan, simply remove two screws securing the

fan.

As you see, the cooling fan is dusty and has to be cleaned.

UPDATE:

There are only two fans listed in the service manual for HP Pavilion dv7 series

notebook. They are listed on the page 27.

488885-001 for laptops equipped with AMD processor.

480481-001 for laptops equipped with Intel processors.

One of the DIY-ers had trouble searching for a new replacement fan for her

AMD notebook. After the notebook was disassembled, she found that it had

an Intel fan installed.

Here’s her comment:

Forget the question I just asked…We opened up our laptop and

found the fan for the Intel processor installed instead of the fan for

the AMD…apparently these ARE interchangeable…FYI

Check out comments 29 and 30. Thanks to Liz for this information.

My HP D7 Pavillion I bought 14 months ago has

Gone completely dead. No power, no sign of life.

From what I am reading here , it seems to be an overheating

Issue . My tech expertise is on the lower end of the scale ,

However the advice offered here is quite encouraging .

I don’t want to screw up the D7 . Please advise me

What might help. Many thanks.

Hallo Ich habe eine folgende Frage an euch ist Der

HP PAVILION DV7 einfach aus einander zu nehmen

ich wollte den Lüfter da reinigen da dreck von Kind 

reingedrückt wurde

If I understand correctly, you would like to clean up the cooling

fan.

Here’s what you can try. Buy a can of compressed air or find an

air compressor. Blow air into the fan grill on the bottom of the

laptop until the dust stops coming from the side. After that blow

air into the grill on the side of the laptop. This should be

enough to clean the cooling fan and heatsing. Do not keep the

air nozzle too close to the laptop or the fan will spin like crazy

and you can damage the bearing.

If you would like to remove the fan, you’ll have to disassemble

the entire laptop and remove the motherboard. The cooling fan

mounted to the bottom case of the laptop as it shown on the

last picture.

So I have half the disassembly done and I have two stripped

screws that will not budge. I am about to call a tech out. What

should I do, and would a tech even step in at this point and take

over?

Fantastic instructions. My hp DV7 1260us had black screen on

boot up (dead CPU according to single flashing led). Followed

dis-assembly instructions replaced Turion CPU and cleaned

fan. Wow lots of dust in the heat sink by the fan. Guess that’s

why the CPU burnt out. reassembled and booted right away.

Saved buying a replacement laptop. Total cost $40 for new

chip.

Dude you rock

@ karl,

Where i can get a replacement for a locking clip?

I doubt you can buy it separately.

Is it broken?

Take a look at this page:

Thank you for this wonderful illustration!!! You helped my 13 yr

old son take apart my laptop, clean the fan, and put the whole

thing back together again! Thank you!

@ Mardi,

but the main problem is that the Laptop turns on,

and lights up, but there is a black screen and the

Caps Lock + Num Lock flash 4 times.

Maybe this error message is memory related? Make sure both

memory modules plugged in correctly. Try reseating them.

Your pictures and simple step-by-step descriptions are great, I

wouldn’t have endeavored without it. However, I found several

discrepancies (problems) while disassembling my dv7. I

checked several sites — same info. One is that the DVD door

should be open to remove it. One site offered an ingenious

solution, but I didn’t try it, I had my own. But, the major problem

s o f a r — I haven’t f inished disassembly to replace the

microprocessor so I can’t say only — is a doozy. Please check

your steps or refer to HP’s Maintenance and Service manual for

the dv7. I found it on the web without going through the HP site.
