Broken Cooling Fan

HP Recommended
HP ENVY TouchSmart m7-j020dx
Microsoft Windows 10 (64-bit)

So, as described I have a HP ENVY TouchSmart m7-j020dx laptop with a broken cooling fan. Or at least that's what the laptop tells me when I try to turn it on. The laptop is only a few years old, was bought in early 2014. By the end of that year I was having an issue with the cooling fan. Something inside the laptop had clearly broken, as when opening it up the casign would get lifted up and seperate. I sent it in for repairs (as it was still under warranty) and last year (2016) it started happening again. Now finally it tells me the cooling fan isn't working so it can't start up, only I am no longer under warranty.

 

This is a very expensive laptop, I don't take it anywhere, it's never left the room, never been dropped, is hardly even picked up off the desk. It's very frustrating to me that it's cooling fan would break twice in under three years but as I'm no longer under warranty I know there's nothing I can do about that. I guess I just bought a $1000 piece of junk with a short lifespan. Reason why I'm posting here I suppose is to ask if there's anything I can do to try and fix this issue. I know HP won't fix it for me but I can't afford a new laptop and I need to have one.

As said, on boot up the laptop tells me the cooling fan isn't working so I shouldn't use it and when the laptop is opened the casing gets lifted up, as if something is loose or in the wrong spot. Any way I can salvage this laptop?

Yes the cooling fan can be replaced and so can the hinges which is likely the problem with the casing. It woulf be a pretty extensive repair project. The parts would not be expensive, but it would take a lot of work in terms of labor. 

 

If you want to explore it I am happy to follow along with you and help with manuals maybe videos, and help you find the parts.

Thanks for the response. The hinges on the outside look fine, there is no external damage visable at all, but I'm definitely willing to give it a shot. As of now the laptop won't boot so if opening it up and trying to fix it is my only option, it's better than nothing. In that case I would certainly appreciate any help you could offer.

You say it will not boot but it posts. and gets you to the 90B fan error screen? The hinges are going to look OK on the outside. What actually goes wrong with them is they stop moving freely so when you try to open the laptop you get excessive torque and it starts pulling plastic case parts apart and stripping mounting screws. 

 

The first order of business is to diagnose what parts it needs and that takes examination. Perhaps some pictures would halp.

Yes, the computer does still turn on, so perhaps saying it wouldn't boot was incorrect. It gets me to the 90B fan error screen and then turns off.

I've taken some pictures but unfortunately the lighting in this room isn't ideal, so I've had to rely on turning the flash on. This suddenly makes all this dust and dirt appear on my laptop I didn't see before so please don't judge me!

Anyway, when closed, the laptop visually appears fine, as such:

Once I open it, the casing gets lifted, as seen here:

And then even once I close the laptop, the casing still stays lifted. I can snap it back shut but before doing so I took this last picture from behind the laptop while in this state. When looking at it from behind I noticed that it was WAY more lifted on the right side of the laptop, so that may be where hatch issue is (although I believe the fan is on the left side, so who knows). Anyway, this is the clearest picture of the hatch itself while in this state.

This is the best I can get without opening the laptop up, which I've never done before. Were these of any help? If not, is there something else I should be looking for?

Just confirms what I suspected. You need to disassemble the laptop by removing the screen and  exposing the motherboard. Replace the cooling fan and replace the hinges. If, in the process of replacing the hinges it becomes apparent that the lower housing or top cover have been damaged they may also need to be replaced.
