HP Pavilion dv7t-3000 disassembly



In this post I will show how to disassemble a HP Pavilion dv7t-3000 series notebook.

This guide should work for HP Pavilion dv7-2000 and dv7-3000 series too.

I’m taking it apart because the notebook gets very hot while running games and other multiple programs. It happens because the cooling module is clogged with dust and has to be cleaned up.

I will clean up the CPU heatsink and replace thermal grease on the CPU (processor) and GPU (video chip). This procedure requires complete disassembly.

If your HP Pavilion dv7 doesn’t look like one in this guide, I have some other disassembly guides. Check out links to related models I post at the end of the guide.

Before you start, make sure the computer is turned off and unplugged from the AC adapter.

Also, make sure to organize all removed screws. There will be lots of them. Make notes where these screws go. This will help you during the reassembly process tremendously.

STEP 1.

Unlock and remove the battery.

    Quick question. Would I have to take ym entire computer apart to replace the USB ports on the right side? One is broke and one just quit working for no reason what so ever. I have the HP dv7-3160us.

  2. thanks a lot for the tutorial, i just removed 30° C by changing the thermal paste!

  3. HP dv7-3165dx looks like the Laptop in the top picture in this guide.
    Can the Fan be replaced without completely disassembling the entire Laptop? if so which steps do I need to follow? Does the Fancy bezel need to be removed from around the edge?
    I was unable to get either of the service doors removed in Step 2 & came to a conclusion my bits for my screwdriver are the wrong size? Do I need bits that are blunt or just a specific size? I have at least 2 sets all pointy/ Deep which didn’t do much.
    My Sis has been out of work for 5 years. We can’t afford to pay a Shop when it means no eating for a month & her fan makes a gawdawfull racket like a Weed Whacker on…

  4. @ Reva,

    Can the Fan be replaced without completely disassembling the entire Laptop?

    Unfortunately, you cannot do that. In order to replace the fan you’ll have to remove the motherboard first, as it shown in the step 37. You’ll have to go though all disassembly steps.

    I was unable to get either of the service doors removed in Step 2

    In this step you don’t have to remove screws completely. You unscrew them but they will stay attached to the cover.
    After that you should be able to lift up and remove both covers.

  5. I think I might need to replace my fan, can you suggest a particular product? Is it generic enough to pick up at a radio shack or something?

    Thank you for keeping up with the questions after all this time.

  6. @ john,
    No, this fan is not generic and you cannot buy it at a radio shack.
    You can buy this fan on ebay for about 10$. Just search the laptop model + fan.

  7. I’m pretty sure I did something terribly wrong because my laptop is much worse than before I cleaned the fans. First off, i didn’t apply thermal grease to the cpu because i can’t get it to buy where i am so i just gave the fans a thorough clean. After putting my dv7-3067cl laptop back together, it started overheating so badly it barely got to the log-on screen before going off. it doesn’t hibernate anymore when the battery is low. The white quicklaunch buttons are lit but don’t work and the orange ones aren’t lit at all.
    I was finally able to change my battery setting to low power and now my laptop stays on, much slower but will turn off almost immediately on a higher setting. After I dissembled my laptop again to check the cables and ran my finger over the touch buttons, the wireless came on but the light is still not lit. I can now control it from hp wireless assistant though. The quick launch lights flickered, dimmed and went off as i ran my fingers over them. Any ideas how to fix this mess?

    You definitely need to apply thermal grease. Otherwise, the laptop will keep overheating.

    Your problem with the quicklaunch buttons could be connection related issue. Make sure the media board cable shown in the step 15 connected properly.

    Can I put a second HD in my HP dv7-3186cl? If so what would I need other than the HD.

  10. @ ron Benninghoff,
    Yes, you can put a second HD into this model.
    You will need:
    1. Hard drive caddy.
    2. 4 mounting screws.
    3. Second hard drive cable.
    Search on eBay for “dv7-3000 hard drive” and you’ll find them.

    I just replaced the palm rest and I followed the super simple STEP 23. Remove four screws securing display hinges (two screws per hinge). This seems like the dumbest question ever BUT i was able to replace the screws on the right side display but NOT on the left side display? I even took the screws out of the right side display and they will not fasten! I don’t even see any threads on the hole for where the palm rest assembly or on the hinge for the screw to thread on to Please advise! I am very desperate as this is my boss’s laptop. Can I just flood the holes with loctite and pray for the best?

  12. I am in the process of reassemble on my dv7-3165dx after finally getting the right fan how do I find out what screw goes were?

    Thanks

  13. @ Dave,

    how do I find out what screw goes were?

    Normally, you make notes or place screws in order while taking it apart.
    You can check our the official service manual for the disassembly diagram and screw locations.

  14. Thank you VERY much, your guide for my HP dv7-3000 was fantastic. After cleaning the head exchanger and reapplying the thermal grease, it runs SO much cooler! Keep up the great work, wish I could donate more. -Garrett

  15. Hi,
    For my sister in law who has a DV7-2230SF , I would like to exchange the hard drive with a SSD.

    I did open the laptop but I dont see how to remove the hard drive (primary one).

    In this video, it seems that there is a specific move to do
    http://youtu.be/PMQ6-ZNGOXU

    can you explain what to do in STEP 4.
    Lift up the hard drive assembly.

    how do you do it ?

    thanks for your help.

  16. @ Hugo,
    There are no screws securing the hard drive. There is black mylar cover on the top of the drive and it has two tabs on each side.
    First, pull up the tab located on the back side. When the back side of the drive lifted up, pull the drive left and up to remove it from the case.

  17. Hi, after following all the steps and re-assembling the laptop and powering on, the monitor shows just a white screen for about 30 seconds, then the computer powers off. Do you know what would cause this? Thanks!

  18. On further investigation it seems my white screen was due to video cable connector not being secure. Now the screen is working, and it is telling me why it shuts off after 30 sec – the bios is detecting a problem with the fan (cooling fan error 902). It refers me to here:

  19. Crap..forgot to reconnect cooling fan wire to motherboard. Dang it!

    I have a HP Pavillion DV7t – 2000 partno. NB406AV
    This step by step procedure was a great help and I completed it successfully and cleaned out the dust,dirt collected in the heat sink-fan area. The PC started right up and ran great but about 50% of the former fan noise came back – so the fan needs to be replaced – did anyone buy a new fan? and where did you get it?
    Thanks

  21. Hi! What’s the thermal pads’s tickness? I want to replace them with high performance pads.

  22. Xavier

    Thanks you so much for this guide! I just cleaned the fan and replace thermal grease. The CPU lost 15°C.

  23. James

    I followed this guide up to taking off the monitor, then put it all back. When attempting boot the monitor doesn’t work at all (even the hp led) and the caps lock light flashes on and off. Also think it corrupted my external drive. Any help?

  24. Kasper

    Hey, Great guide!!
    The laptop is so much cooler now, but I have a problems, after reasempling the laptop and powered on, it says that the battery are not charging, and it can only start with the power cable in it!! O_O
    Have I damaged something?

  25. Kasper

    Oh, I forgot to mention that it is a HP Pavilion dv7t-3000 laptop ☺️

  26. Benqazy

    Please I followed the guide and had my laptop keyboard tag cleaned but it seems that the “tab key” is continuously working it only stops when I press the shift key a couple of times and start to do that again and i had to press the shift key a couple of times again and its really annoying me any time I want to type something on the keyboard it freaks out and its really disturbing . And also my left Shift Key is not working. I already had this problem before that’s why I followed this guide to get to clean the keyboard tag I thought it would work if I do that, but still same problem. ANY HELP PLEASE?! Thanks in Advance.
