HP Pavilion Fan Error

[The Bad Guy]

On my wife's laptop got an error yesterday - 90b on startup that says something wrong with cooling fan.

I updated BIOS because it appeared that the fan was working some but it's not working at all now.

I'm looking to purchase a replacement fan but haven't gotten the slightest idea what to even look for. Some say you need fan and heatsink, some say you don't.

It's an HP Pavilion G7 - model A6Z19UA#ABA.

Can anyone lead me where to potentially purchase a good replacement?

How difficult are fans to replace in laptops?

Thanks in advance for any help.

If you have an air compressor - simply blow out the vent slots on both sides, this will 'free up' the fan, often dust and debris will lock these up.

I bet this will solve your issue.

Thanks SR. I tried that with my dad's minicompressor before I took it apart. There was nothing obstructing or a dust issue.

I have to shut it down via the power button on the case.

Did you try uninstalling the System monitor app and then running Coretemp.

You could also try Realtemp - http://www.techpowerup.com/realtemp/ or Speedfan - http://www.almico.com/speedfan.php both work well.

One thing to try is a Bios update.

Yep. Very unlikely that even 1 fan header is bad actually. Very simple circuit.

CoreTemp causes your system to freeze? That's very odd.

Dang, well ok, this happens to us from time to time - w/ the Thinkpads, but they always self correct after I do that.

Hmmm...
