The fan on the processor keeps coming on real loud


The fan is supposed to come on to cool the processor but if it is making excessive noise then I would buy a new one before that one give up completely and you damage your processor. they are cheap enough to buy on line, you might need the motherboard make & the processor you are using to get the correct replacement but you can get CPU fans that have universal fittings in which case you would only need to know what processor you have.

I had a pavilion dv4-1430us for over a year, recently I started up the fan was very noisy like a bearing noise. what should I do? thanks for the advice


If you have no experience with opening an repairing computers or laptops I recommend you take the computer to an HP Laptop Service center. If you understand the issues involved you can order a cooling fan from HP and install it yourself as long as you keep track of the screws in the outer case and where they go as well as any cabling.

My pavilion dv7 is saying "boot device not found". It is saying there is "no hard disk". Any suggestions appreciated.


I would want you to tell me if your Laptop feels hotter than usual.

If so... this in combination with the Boot device not found message means you may have two problems.

1: The hard disc is failing

2: Your cooling fan isn't working

Either one could cause the other to fail. If the hard drive is overheating the cooling fan may not be able to keep it cool enough to function properly,


If the cooling fan isn't working properly or the cooling vents are clogged the hard drive and/or the intergrated circuitry could be overheating

If you do not sense any over heating.

You hard drive may have crashed, if you have another one you can put in the laptop to see if it is recognized.

Would help to have some sort of disc you can boot off of that would recognize a hard drive such as a Linux live CD or Hiren's boot CD or some sort of PE disc. Maybe a Windows install disc. to try and find out the cause.

Good Luck

My cooling fan has stopped working - laptop is a hp pavilion, model tx2000


If you unplug the fan, you can test the connector to make sure the fan is bad and the problem isn't with the power getting to the fan.

You can get a new fan and heat sink assembly here (make sure the model number is the same as your computer):

But in the meantime, you shouldn't run the computer much because it can easily overheat without the fan.

Hp pavilion a450n problem fan is running on high and keeps shutting down


First off - have you ever cleaned inside the case? You'd be very surprised how much dust often builds up inside a PC. After that it sounds like you might have another fan which has failed. PCs often have more than one inside and they also have temperature sensors to keep the CPU cool. If a case fan has failed it would not have air flowing inside to cool off the other components and then the CPU sensor would kick the processor fan into "overdrive". One thing to note; the difference between a two wire fan and a three wire fan is that the third wire is used to confirm the speed of the fan. Fans are usually easy to replace - just get the right size and the same right plug.

My hp pavilion dv1000 fan turns on for a little bit then turns back off.Do I need to replace the fan?


Hi,

Are you having any problems with the laptop overheating or shutting down unexpectedly?

Generally the fan should only run as much as it needs to in order to maintain an optimal temperature. the fan will be turning off as the laptop will be cool enough. if however, the laptop is very hot to touch you may have a faulty sensor telling the fan the laptop is cool when it isnt. this generally leads to the laptop crashing or shutting down though if thats not happening i recommend contacting HP for guidance.

it is most lekely functioning properly if you arent having any other adverse effects

Thanks

Display and Boot problem with HP Pavilion DV2125NR


It is normal for the bottom to get hot. The fan should keep it cool enough to run, but it sounds like perhaps your fan is not working very well anymore and should be replaced.

Does the computer act up at all when cool? If not, the first thing I would try is replacing the fan and examining the fan and heatsink assembly for proper installation, perhaps replace the heatsink compound with some Arctic Silver while you have it open.
