HP G62 Laptop fan issue, fan no longer working HELP

[alextee]

Basically i have a HP G60 laptop and cleaned my fan with compressed air and it stopped my laptop overheating etc etc.

HOWEVER my other half has a HP G62 laptop and her fan is LOUD and is on the verge of overheating and shutting itself down.

So i used the compressed air can to clean her fan BUT it completely stopped spinning and now i get the error message saying the fan isnt operating properly and its not advised to continue with normal use. 

I can get onto windows. but the compressed air (Which EVERYONE recommends) seems to have completely either broke the fan or blown dust INTO the fan and stopped it. 

After many restart attempts it came on breifly making this ticking noise as if the blades were hitting something as it spun (which was slow might i add).

MAYBE the bios has detected the fan was blocked and stopped attempting to spin??? i dont know i need help or advice before i dismantle it to try and clean the fan manually. 

which i KNOW is quite fiddly for an amatuer. fans should be the easiest thing to get to not the hardest but oh well...

HELP PLEASE

Hi Alex,

Well, the first bit of bad news is that there are right ways and wrong ways to clean fans with compressed air... You MAY have done it. well, not in the best way.  Let us assume you did it right and it was not enough of a good thing to save that fan mechanism.

The second bit of bad news is that you CANNOT run the notebook without a fan. 

You may consider:

• Crack open the case and commit to fixing the notebook
• Take it to a reputable shop and have it repaired.

Understand it may not be "just the fan".  It could be slightly more complicated or way more difficult.  It is the nature of computer repair that things can start out easy and end up with parts spread all over the table.  Be prepared for either end of the spectrum.

Look for a Repair and Maintence Guide for the G60:

Start at

Support and Drivers

Add your exact notebook model, look on the left for Manuals, hope there is a Maintenance Guide and download it.

• Prepare a clean worksurface.
• Get some bowls for tiny parts.
• Prepare your tools...
• Add some light, then more light.  Things look less intimidating under lots of good lighting...

Search for a YouTube Video on how to do this.... There should be lots of help.  I won't pick for you.  Everyone has preferences on how to learn to do things and what works best for them.

Good Luck!

explain to me the wrong way of doing it?
i have seen videos that say use the compressed air in short bursts and first of all through the fan intake (underneath) and then the fins on the side.
do you think i have accelerated the fan too much and ruined the motor? my girlfriend is a bit sceptical of my capabilities haha. I know you have to pretty much take everything apart to get to the fan on a G62.
Also i dont want to remove anything because i have seen somewhere that i should be replacing the thermal paste or pads if i do?? Just gutted that i tried to help and broke her fan. I also did this to MY laptop, which solved the overheating problem but maybe i over-did it with the air and the fan also stopped working after a while (i probably did the same thing as i did to my girls laptop.)
BUT after about a year of it being on a DIY fan table my laptops fan decided it wanted to come back to life. and now i dont need it on the fan device haha.

Primarily, the "right way" consists of disconnecting everything (power, battery, all external devices),

using short, clean bursts of the air,

blowing in the direction that the fan normally turns.

It is possible to make a bad situation worse, of course, but doing nothing might have eventually a similar end result:  notebook on the worktable. 

Trying to fix something is a good thing in my book. 

Failure is never the result of trying, failure is the result of inaction.

Replacing thermal paste goes beyond replacing a fan. It works.  It may or may not be a DYI project.  As long as you don't actually damage the harddrive(s), at least the data should be safe even if you further damage the system.

If the girlfriend is not happy, all things in the universe can end up like the fan.  You could ask her how she wants to proceed - it's her notebook, yes?

I hate to give hard core advice on hardware I can't see; I hesitate to give that advice on hw I can see if it's not mine.  I have backup systems - if you don't (and therefore cannot do without this system for a long time if you cannot fix it fast), then you might consider having the box repaired by someone who is not personally involved.  It could be far less traumatic.

Regardless of what you decide, make sure everyone agrees on the course of action. 

It matters what you do next more than what happened to bring you here.  Smiling.

BTW:  I am a firm believer in notebook coolers.  Something to consider for later... You can do a search on my many posts on the subject.  I do tend to "go on" about the subject.  Smiling.

Good Luck!

i have a belkin laptop fan cooling stand which i advised her to use for the time being. (while i decide if im going to attempt to take the laptop apart with instructions in the hp manual.. or not.
i love cooling stands cause my fan on my HP G60 packed in (i think the same thing happened, used the compressed air wrong) for almost 2 years and survived on a laptop cooling stand (and various other small fans attached to a table haha). miraculously after all that time my fan decided to work one day, and i am able to take it away from the cooling stand now.

i hope the same happens with her laptop, but i like projects (as long as they go well) so might attempt to take it apart and maybe unplug/clean the fan then re-assemble and hope for the best.
failing that i might reset the bios, does this affect the content on the laptop? Or anything to do with it?

just to let you know i have fixed it, the fan seemed completely broken with no movement and its cos i spun it too fast with the compressed air or blew the clumps of dust and lint back into the fan and clogged it. either way i just got it working by taking a womens hair pin and poking it through the slot carefully and turning the blades, it got a bit difficult like there was something stopping it, but after i pushed past that point i spun it with the clip a few more times then it fired up no problems when i powered on.
thanks anyway your advice was spot on!

Alex,

Excellent! Good job!

Thanks for posting back - it is helpful for others to know that persistence and a delicate touch can be the key to success.

Here is a familiar document that has been around for a while.  The pictures are startling.  They make a good point for keeping the notebook away from dirty environments and making sure the vents are cleaned on occasion.  Smiling.

If your fan spun during the blow out, you are doing it wrong.  When cleaning a fan and/or heatsink fins, you should ALWAYS use something to stop the fan from spinning.  Otherwise, much like an alternator on a car, the spiinning will produce electricity and send it back to the mobo... NOT GOOD!!!

I just fixed a fan problem on a G62.

Fan stopped altogether during operation.

(It is normal to hear it go up in speed as it heats.)

Bought a new fan, but didn't need it.

I disassembled via the service manual to removing the top cover.

Once here, I had access to the fan for further diagnosis/cleaning.

I saw fluffy chunks inbetween some of the fan blades and the fan was VERY stiff to turn as compared to the new fan.

I used tweezers to pull this stuff out, and the fan spun with about the same ease as the new fan.

Did a quick power on test (had to put the cover on and connect the power button connector) and the fan spun up fine.

Vacuuming and using a small brush to clean things n computers is far far better than pushing air around.
