Only do this if you feel competent in doing so.

Pulling apart laptops is not for the faint of heart.

If you really must do it there are some
good guides here
.

An alternative is to get a can of compressed air used to clean computers. Put the nozzle on and spray it in every hole you can see without putting the nozzle itself inside the laptop.

Do this outside with glasses on.

Thats because there are hidden screws.
You also have to remove the hard drive and ROM drive.

Take a
peek here for more ideas of what is involved.

There are a few are tips for various things in there.

DON'T touch the CPU cooler unless you know what you are doing and have some thermal grease for CPUs to hand.

Depending on the noise, these are "most likelies":

Constant clicking like whir - something got sucked up and/or stuck & the blades are hitting it. Get a can of compressed air & try to blow out & clean the air path of the fan. IMPORTANT!!! DO NOT USE AN AIRHOSE FROM A COMPRESSOR!!! Two reasons for this are 1] the air pressure coming out of there may be too much & will cause severe damage to your laptop. 2] most air compressors collect a lot of moisture from the process of compressing the air, {among other small things}. Even the best 'moisture traps' will allow enough to get through to REALLY muck up any electronics without showing, do not take that chance.

Rubbing groaning or surging type of sound: This is usually an indication of the bearings going bad, and will require replacement of the fan itself. I have had this happen on several laptops. If the system is in warrenty - take it in. If not & you feel confident with small parts repair, go ahead & try the replacement but be very very coutious & detailed in doing so because it is really easy to damage the case & internal parts of a laptop. "the fix is easy, getting to it is the pain"

My pavilion dv6700 won't turn on. The lights come on then the fan starts only to all shut off and then continue the same process.


HI there. We'll I hate being the barer of bad news but the HP DV series of laptops have been having a lot of issues with losing video, continually restarting, or just plain do nothing. Hopefully your laptop is still under warranty or someone else knows of a quick fix. I've had to send out the motherboards for 2 of these to get fixed. One of them ended up being the video card on the board. And the other ended up becoming a replacement motherboard.

Here is a link to what other people are having to deal with on their Hp's.

Hi my dv 9000 makes ugly sound-noises


If it is the fan, it may simply be cruft inside the brushless motor. It is possible to fix this following HP's manual at: http://h10032.www1.hp.com/ctg/Manual/c01311536.pdf
Once you gain access to the heatsink/fan assembly (this takes 6-90 minutes), you can remove 4 small screws, remove the fan from the motor, and clean it out. This worked for me.

Warning, many components are very ESD sensitive, and the flat cables and connectors are fragile.

Note to HP: Please make these easier to service! Adding a removable panel would have made this a 10 minute operation.
