Hi,

It sounds to me like the CPU fan and the air vents need a good cleaning.

Noisy fans and them running for a length of time means that its having to be on more to keep the processor cool.
Other causes of the fan being load and on is gaming and heavy programs. The more the processor has to work the hotter it will get.

Have a look at your air vents and the CPU fan for dust. If you see any dust then you will need a can of compressed air to blast through the vents and CPU fan blades of dust.

Removing the dust from the machine usually quietens them down.






Regards.

It is set up to run if CPU gets warm/hot. Quiet normal.

If it didn't you would son know. One Cooked CPU with Chips. Expensive tak Away.

Some fans are noisey. You could go to the expense and have a replacement???

Go to Driver - Network, and select the bluetooth driver. Bare in mind, not all HP Pavilion dv2915nr supports bluetooth. But, if your laptop does have bluetooth and you installed the drivers, but still not working, your bluetooth card might be faulty and must be replaced.

Sony Vaio fan making noise


Hi:
Not sure of a user cause for the fan to run full speed, unless you are using the laptop in a high heat environment, or setting it on a bed or other area where it is not getting adequet cooling air. If it does it right away, when you turn it on , cold, then there might be a laptop hardware problem. If you leave your laptop on all the time, then you might be inducing the problem. I had a HP high performance laptop, that the fans would not turn on at all till it ran an hour or so, then they would stay on loud for 10 or 15 minutes, then shut off, then cycle.

My HP Pavillion notebook dv6000 was brand new a little over a year ago. Unfrotunately i didnt get the extended warranty. Anyhow, its had occasional issues from almost the start with it overheating and...


I have rebuilt so many of these laptops, I dream about them. HP did a lousy job with this design...Get the latest BIOS update for it that you can first....supposedly the new BIOS has an advanced algorithym for the fan running to help with cooling....I haven't seen any real changes....What I do is remove the heatsink and clean the contacts between the heatsink, processor and video card. I then put a very thin layer of thermal paste on all surfaces, then between those, I install small squares of 100% pure copper sheet about 1/2 inch square in size. The copper plate has been the trick for me along with a thin layer of paste. Do not put the paste on thick, that actually will reduce the cooling capacity of the paste.

Below is the repair and service manual for your laptop.

Hp 6720s lap top running - vista does not load


If the laptop runs extremely hot, then CPU will shut down (thermal overload) and will not boot up again until it has cooled down.
Overheating problems is caused by faulty fan (stop spinning) or the fan and heatsink assembly is clogged with dust. Check the fan, it should spin freely and remove and vacuum the dust from the fan and heatsink.
Replace the fan if it is faulty.

PC suddenly shuts down on its own.


in this case pc only shuttdown automatically when the sensor of processors detects or reach the maximum temperature of the system. try to check the CPU FAN if running poperly. RAM also causing sudden shuttdown.
