Question about HP Pavilion dv9000z Notebook

1 Answer

A grinding sound from the fan area at the upper left of the base

My laptop has just begun to produce a grinding noise from the fan area at the upper left of the computer. When listening up close with my ear to the vent, I can hear the fan operating (it seems quietly) with this sound over the normal whir of the fan. It sounds a bit like an automobile's ac/heater fan that's got a leaf stuck in the works. Occasionally a noise like trickling water introduces itself into the mix.
The vent area is clean, recently vacuumed.
My laptop is 19 months old, is used eight hours daily.
What could be going on?

Well theres more than one fan on the inside of your computer, so its possible it could be dusty and its setting the fan off balance. its also possible you have a defective fan inside and this sounds like a hardware issue, its possible theres a service enhancement on this model so i would call tech support to see if it can be sent in for repair, i know its not what anyone wants to hear but i do not suggest opening it yourself as it can be hazardous (i.e you get electrocuted)


Note: this could also be cause by overheating or being dropped (theres numerous other things but those sound like the most likely alternatives)

Def sounds like the fan , from where you say the sound is coming from . normally the fan should be able to be cleaned the panned holding the fan in the left hand corner . clean the fan with compressed air , or a paint brush . if this fails then you need a new fan .

My problem with my Sony VGN-SZ330P is the fan, it producing some loud noises, sounds like its grinding something


You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

Grinding noise when fan spins fast


Try cleaning out the fans before going to the bother of replacing it. There maybe some debris stuck in it causing the strange noise. A can of compressed air often removes most of the dust and debris but on occassion it is necessary to open the case and manually clean the fan.

Generally if its grinding and clicking noises it will be the hard drive the fans will cause more a whirr than a grind

A loud grinding noise comes from the fan area


Check if there are dust debris on the fan, it could create a grinding noise, but if the fan is clean, there could be a mechanical problem with it. Hope this helps
