In this guide I explain how to disassemble an HP Pavilion dv7 notebook.
This is my first disassembly guide for HP pavilion dv7 series.
To be precise, I’m taking apart an HP Pavilion dv7t-1000 notebook.
UPDATE. READ THIS: I found that HP Pavilion dv7 notebooks come in different body types. If your laptop doesn’t look like one shown in this guide, check out my second complete HP Pavilion dv7 disassembly guide (for dv7-3000 and dv7-4000 series) or my third HP Pavilion dv7 disassembly guide (for dv7-6000 series).
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.
If you need spare part for your HP Pavilion dv7 notebook, you can search here.
STEP 1.
Remove (loosen) four screws securing the hard drive and memory cover. Remove the cover.
STEP 2.
Remove four screws securing hard drives (two screws per hard drive).
Slide the hard drive 1 to the left until it’s disconnected from the motherboard. Remove the hard drive 1.
Slide the hard drive 2 to the right until it’s disconnected from the motherboard. Remove the hard drive 2.
STEP 3.
Remove both memory (RAM) modules.
Disconnect two antenna cables from the wireless card. These laptop has three antenna cables but only two are used.
One of the antenna cables connected to the main contact on the wireless card and the second one is connected to the auxiliary contact. All three antenna cables are labeled.
Remove two screws securing the wireless card. Remove the card.
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.
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.
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.
You’ll find more info here: Fixing damaged keyboard connector on a laptop 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.
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.
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.
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.
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.
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.

Thanks so much for this page, I used it to replace the motherboard in my parents HP DV7 1132nr. It’s working like a charm now!

Hello , i used this guide to clean the cooling system of my laptop.But i am having a hard time , identifying which is the correct side of the fan cable molex.It fits in both sides.I am surprised that none had that problem.

Mel Baker,
There is no way I can tell what is wrong because I don’t know if the laptop assembled correctly.
In most cases the laptop will not start because or incorrect reassembly. Something simple like loose memory module or incorrectly connected cable.

Doug,
Sounds like overheating problem. To be honest, I don’t think that cooling stands help a lot.
Laptop overheats when the cooling fan and heat sink get clogged with dust. You can see the cooling module in the step 20. It’s located in the upper left corner.
Before you disassembled the laptop try cleaning it with compressed air.
Blow compressed air into the fan grill on the bottom of the laptop and after that blow it into the grill on the side. Do it until the dust stop coming out.
Test the laptop after that. It should take care of the problem.

I have a 17″ HP Pavilion Entertaiment Laptop Model # DV7-3079WM. It is 17 months old and runs windows 7.
Over the past few months the unit has been getting ‘hotter’ than normal and it sounded as though the fans were working overtime. I eventually got a cooling stand to use it on but last week the laptop started turning itself off. Now it reliably turns off within 5 to 45 minutes of being turned on and cannot be turned back on again for awhile. [It clicks on, buttons light up and then it clicks off immediately.]
I managed to run virus, spyware and malware checks and nothing turns up so I’m confident this is not the problem. I installed Core Temp and watched it prior to the laptop turning off and did not notice elevated temperature readings so I’m not sure it is overheating… especially since it turns off sometimes after only 5 minutes.
I’ve decided to open up my laptop using your guide but ask if you could PLEASE tell me what parts you would look at to remedy this issue! THANKS!

Greetings,
I noticed a few users had trouble after re-assembly with no boot/panel lights flash once. This has happened to me also on a pavilion dv7 1448dx. I also see you had no response to these comments. Could it be that this is a DOA situation? Any comment at all about this, it is a friends machine so I am responsible for any damage.
Thanks

Thank you soo much, i have had such a hard time finding a dv7 dissasembly explination, just wondering, is it necessary to take off the monitor and such just to access the fan and the heat sink? Having a serious overheating problem, reaches 110 degrees in little or no time. i’m thinking i need to clean the fan, and maybe reapply the thermal paste to the heat sink?

Thanks very much for this info. I took it apart, then put it back together, now the keyboard doesn’t work. There are 2 micro ribbon cables that need to go back, but I don’t know which way is ‘up’ with them, because I took it apart on Thursday, and put it back together on Sunday. Any hint on that would be helpful, as I start to unscrew the whole damn thing again. Thanks.

I got as far as trying to remove the speaker cover but I couldn’t manage it. I cracked out both sides with a pick like you said but the middle section seemed really strongly attached to the motherboard and it felt like it would break if I had used more force. Is it possible I have a different dv7 model to yours?

Thank you very much for this guide. Was able to disassemble my laptop and finally clean out my fan as this has been causing my computer to overheat a ton. I’m embarrassed by how much dust was actually taken out, lol. But it’s all clean now and I was able to put everything back together and she runs great now.
Thanks again!
