    • The laptop should now look like this.

    There is a horizontal grey wire in the middle of the picture. There is no additional showing where is goes on the left.

    I was careless when I completed step 15 documentation. Now when I am in the process of reversing the process, I don’t know where to connector.

    Need a 19.5 step showing what is happening in this area of the laptop.

    • CAUTION: Be careful not to bend or break the motherboard body or USB ports.

    Thanks for this helpful guide! But 2 edits were necessary, one in this step to avoid breaking something.

    Other than that everything went well. So thanks again!

    My raw edit:

    "WARNING: motherboard can't be removed without removing the 2 screws holding the fan to the laptop body! That edit for their position (not clear in this shot) was declined. I would have broken something if I kept on pulling with those screws too in place."

    I added a new picture showing clearly at least one of the two screws, but positioned the marker also on the other less visible one.

    At this point I still had two wire harness connections to the underside of the motherboard that were preventing it from lifting out.

    Jeff Slutz - Réponse

    The two screws by the fan are indicated on the second photo, but perhaps would be better to also indicate them on the first photo. In addition, similar to the other comment, I also had two wire connections that were still connected that prevented the motherboard from lifting out, but they were easy to see and easy to disconnect, but this should be added to the instructions.

    En este punto no es posible sacar la placa. Faltan retirar dos tornillos del fan, el conector del CDROM y descalzar/levantar el parlante superior.

    • Flip the motherboard over. Use a micro- screwdriver to remove the screws holding the fan assembly in place.

    • Note: You may need to cut or remove a bar code sticker from the fan/heat sink assembly.

    • Remove screws from the heat sink assembly using a #1 Phillips screwdriver.

  21. HP Pavilion dv7-6c90us Cooling Fan Replacement: étape 21, image 1 de 2 HP Pavilion dv7-6c90us Cooling Fan Replacement: étape 21, image 2 de 2
    • Remove the fan/heat sink assembly.

    • Note: The assembly may stick, due to the connection made with the heat sinks through the thermal compound.

  22. HP Pavilion dv7-6c90us Cooling Fan Replacement: étape 22, image 1 de 2 HP Pavilion dv7-6c90us Cooling Fan Replacement: étape 22, image 2 de 2
    • The old fan can be removed by sliding it out of the fan/heat sink assembly.

    • Note: You can use canned air to clean out the fan vents for better CPU cooling.

    • Insert the new fan into the fan slot in the fan/heat sink assembly. Put the assembly back together with the micro screws.

    • Before reassembly, make sure your new fan freely rotates within its housing.

    • CAUTION: Do not over-tighten the screws!

    The raw edit for "Before reassembly, make sure your new fan freely rotates within its housing." is necessary to avoid going through all of the steps again. I had to use a screwdriver as a wedge to widen the fan's housing distance from the fan, and blow into it to verify free fan rotation.

    • Use cotton swabs, paper towels, and alcohol to gently remove old thermal compound from the fan/heat sink assembly and motherboard.

    • CAUTION: Do not pour rubbing alcohol on the motherboard or other components! The rubbing alcohol may cause severe damage to your computer.

    • Apply a small amount of new thermal compound to the center of the brass section of the heat sink. Both areas that need new thermal compound are marked with red boxes.

    • CAUTION: Use the thermal compound manufacturer’s recommended amount. Applying too much or too little of it may damage your computer.

  24. HP Pavilion dv7-6c90us Cooling Fan Replacement: étape 24, image 1 de 2 HP Pavilion dv7-6c90us Cooling Fan Replacement: étape 24, image 2 de 2
    • Re-attach the heat sink assembly to the motherboard.

    • CAUTION: Do not over-tighten screws. Finger tighten them until snug. If you apply too much torque, you may damage components.

    • Using light pressure, shift the fan/heat sink gently back and forth to spread the thermal compound. This makes a solid connection between the heat sink and motherboard.

    Nice manual. I always use this one when I am laying hand my notebook. I would just say that it takes less time: I need around 3 h to disassemble, clean and reassemble.

My HP Pavilion dv7 Cooling Fan failed and this procedure was exactly what I needed to install a new fan. The steps are right on. I would have done a lot of experimentation and possible damage had I not had this reference to follow. Thank you very much.

Thank you so much! I just did this today following your directions, with my husbands help. It took us a little less than 3 hrs. All is well, actually great! My HP dv7 is up and running great! Thanks again. I'm sure without this guide I would have goofed up somewhere.

Extremely helpful, thank you so much.

I did have a bit of a hiccup. When pulling the heat sync assembly off the motherboard the thermal compound let go suddenly. The assembly ended up hitting a capacitor and popping it off the motherboard. I managed to do some very tiny soldering and put the capacitor back on the board (seems to have worked).

For my edification and others’, is there a better way to pry the heat sync assembly off the board? Some sort of tool to put beneath it somehow and gently pry it loose (without somehow damaging the CPU or GPU?

Thank you for the time and effort putting this step-by-step guide together. It was extremely valuable in helping me restore my laptop to original performance. Job well done!

This guide was invaluable, my fan was jamming and I had tried an external exhaust fan with little luck. I needed to keep my computer running to support legacy software. I managed to complete the task following the steps.

To the author, one thing.

Your a God! , without you, I would’ve had a pile of junk leftover and a bunch of screws.

Thank you very much!

Really useful guide - it made the job very doable. The DV7 I was fixing also had a biometric fingerprint reader to disconnect and re connect that was hard to get to.

I did a time lapse video of re assembly for some fun…

This instruction was a gift!

It was very accurate in most places and enabled me to successfully replace my dv7 fan in about 6 hours. I never would have even attempted it without this detailed procedure. I imagine a computer shop would have charged hundreds of dollars for this repair. I gained enough confidence that I would attempt other repairs on my own now.

There were a couple of issues: There were several connectors still holding the motherboard in place that were not addressed. One was the backup battery, two other connectors on the bottom, one near the card reader and a second small display connector near the fan - easily handled though.

The only real problem I encountered was removing the top cover. It made popping sounds as I pried it up all right. Turned out some of the pops were locking catches and the right-rear threaded insert breaking off. Still it went back together ok and worked perfectly when I turned it back on.

Thank you!

First part to fail. Hardest part to access. Would have been nuts to pay someone to do this repair. Thank you for this!!

Your steps and instructions were perfect and provided the guide I needed to replace the CPU fan. I agree with the other commenter that there were a few additional plug connections that had to be disconnected but they were very obvious and easy to do. I actually drew the picture of the bottom of the notebook with the screw locations on a folded-over large piece of cardboard. Each screw I would sink (punch) into its location in the picture. It worked great. Thank you so much for your time and effort to help us all! We owe you.
