HP Pavilion dv7 Disassembly

Hello,
I would like to disassemble my HP Pavilion dv7 1070ef laptop. I want to access the fan to clean it because I have a problem that probably comes from dust. Basically, whenever I switch my PC to "Normal Usage" or "High Performance," it overheats and shuts down quite quickly. So I'm forced to stay in "Power Saving," which is not practical for gaming :x
If you think the problem comes from somewhere else, I would like to know^^
Otherwise, I'm looking for how to disassemble my PC because I can't reach the fan...
Thank you in advance!

      Hello

      I need to replace my hard drive which overheated and burned out

      The PC is still 5 or 6 years old and it runs at least 5 to 10 hours a day ^^

      The manual is nice but it's in US!!

      Is there a French version available??

      Thanks

    Hi, here is a link that explains this issue well: http://gnu-shoot.net/?post/surchauffe-hp-pavillon-dv7

    I think the same procedure applies to all dv models.

      It's almost impossible to disassemble certain HP DV7 models; it's done intentionally to damage the computer... In 99% of cases, it's the accumulation of dust, so the easiest solution is canned air. Otherwise, instead of breaking the computer by opening it, just vacuum over the intake grille located underneath the device, and if the fan is still blocked, break just a tiny part of the plastic grille to extract the clump of dust with a household vacuum cleaner, getting closer gradually to remove the dust buildup.

      There's nothing to break on a laptop, everything can be disassembled.

      Stop the misinformation

    Hello,

    I also had this problem with my DV7-3165ef.
    The temperature of the graphics card went up to 110°C, resulting in FPS loss in games and frequent "freezes."
    So, I took it apart (about 3 or 4 hours including reassembly).

    I was very surprised to see that the fan was absolutely not dirty; however, the thermal paste was completely dry, so I replaced it.

    Since then, it runs like new, with a temperature drop of about 15 to 20°C.

    The link from pepito10 is still valid: http://h10032.www1.hp.com/ctg/Manual/c01918142.pdf

    Make sure to reconnect the fan power cable properly; I made this mistake, and the computer won’t start in that case.

    Good luck!!!

    hi everyone

    I am also the "happy" owner of an HP Pavilion dv7 4090 ef with an overheating problem as well... After two visits to the service center (first time by HP and second time by Surcouf), I find myself still facing an overheating issue, but the most annoying thing is that the hard drives are failing one after the other. Cleaning it doesn't seem to be enough. Does anyone have another idea about the problem???

    No one has any idea to solve my problem?

      Mine was climbing to over 100 °C, with the fan running at full blast all the time. A blast from an air compressor in the ventilation openings allowed me to see how much crap there was, and I immediately gained between 40 and 50 degrees.

      easy to take apart like a PC, honestly guys, think hard and go for it!!
      and for your overheating issues, dust off the fan and remove the dust layer between the fan and the radiator.
      mine went from 85C to 51C.
      do it every 3 months, especially if you smoke.
      have a great day everyone

    I have the same problem as you, but the link you provided no longer works. Is there another link, please?
    Thank you in advance.

    Hello,
    I indeed also have an overheating problem, but dismantling my dv7 is impossible; I can’t find access to the fan. The thing is, your plans in the links do not match my dv7. The rear panel configuration is not the same, and the top is a single piece that cannot be disassembled only from the top near the keyboard. Does anyone have an updated plan? I can't find anything on HP.

    Thank you very much.

      Hello again,

      Today I went to my usual computer repair shop, and we looked at how to remove the top case. I had already taken out the battery, the hard drives, the memory sticks, the Wi-Fi card, the CD/DVD drive, and all the screws. Then you need to slide a small flat screwdriver between the top of the keyboard and the cover to release some clips. After that, you disconnect the keyboard tab. Once the keyboard is removed, two screws need to be undone to take off the cover. This gives access to the motherboard and the fan. To remove the motherboard and take out the fan, you need to unscrew the screws marked with small white arrows.

      There you go, I hope this helped you a little bit.

      For disassembly and maintenance guides, you need to look on the following HP site: http://h10025.www1.hp.com/ewfrf/wc/siteHome?cc=us&destPage=siteHome&lc=en&tmp_docname=.

      In my case, I then searched for "pavilion dv7-6190ef". I then went to "Manuals", and then I downloaded the pdf titled "HP Pavilion dv7 Notebook PC - Maintenance and Service Guide >": http://h10025.www1.hp.com/ewfrf/wc/manualCategory?cc=us&dlc=en&lc=en&product=5131767&query=pavilion%20dv7-6190ef&tool=&. This guide is available in English, but not in French.



      That's it, best of luck.

      Tested and approved for a dv7-3165ef, unlike the rest (build quality, support quality, value for money) these manuals are truly an anomaly!
      After a thorough cleaning of the fan and the cooling system, applying a new thermal paste, it's simply night and day!!!

    Hi, I have an HP Pavilion dv7 4171-SF. I had the same problem as you, so I started with a video on YouTube ( https://www.youtube.com/watch?v=MyzoRVp297s ). You need to remove the hard drive, RAM stick, processor, keyboard, motherboard, and finally you'll get to the fan. Make sure you have the right tools, as well as a brush, and go for it; it's not very complicated.

    Hi,

    Have you tried using an air compressor or a blowgun?
    To be sure it’s heating up, you should check the temperatures, but I think your diagnosis is correct.

    Anyway, here’s the manual; it’s still not easy to disassemble a speaker.

    Look at "removal and replace...."

    Oh, thank you very much, but it still looks really complicated to open...
    To access the fan, you have to take almost everything off!!
    I might try a can of compressed air; I need to go buy that...
    Does anyone have any other ideas by any chance?

    Don't you see the fan when just removing the keyboard? It would be more practical for blowing.

    No other solutions, I have the same problem, I will have to take it apart.

    I had the same problem, my PC (bought two years ago) was overheating abnormally, the fan underneath wasn't working anymore... unable to take it apart, I vacuumed around the fan and used a needle to push the fan blades... then the fan started working again. I then vacuumed again and big clumps of dust came out.....

      Yes, but to replace thermal paste that has dried up, I believe there aren't really 36 solutions.

      My fan, besides running all the time and not stopping an abnormal rise in temperature for simple tasks, squeaks.

      I was vacuuming through the grill, causing the small blades to move (and indeed, after a few movements, the vacuum picked up nothing less than dust bunnies!), also vacuuming all the ins and outs (grills, ports, etc...), but that's no longer enough.

      (my PC is 3 or 4 years old).
      A BIOS update (I don't know what that is) is also suggested here and there to try to solve the overheating problem.
      But I don't think it affects the mechanics (and especially this squeaking, for example).

      There is also a video on YouTube showing a guy disassembling his dv7 laptop: a bit barbaric and messy, but ultimately everything is there (at least I think so, I know nothing at all about programming or computer hardware):
      http://www.youtube.com/watch?v=kAmBtQztEQw

      There you go.

      Thank you, to those who posted it, for the updated link to the manual.
      (I don't know how you do it: I hate the HP site: I rarely find, and sometimes by miracle, what I'm looking for, in this case: a disassembly guide).

      I'm not daring to dive in yet, but I really don't want to wait for the PC to give up.
      So that's what I've gathered on my side.

      Good night!

    Hello,
    For this computer, I believe everyone has overheating issues.
    I have researched a lot, I took it apart to clean it, but you should know that right from the purchase it makes a lot of noise from the fan, and I really think the manufacturers messed up with this series. To be honest, there’s nothing that can be done; I’ve tested everything, even took it to a specialist and changed that part, but it’s still loud, still heating up, it’s a disaster. The upside is that it’s powerful, but anyway, you can't have it all with this one.+++
