Are the fan in lap top supposed to run always?

Now I am able to understand the happening. My fan will start running with a noise some time and if I check the bottom of the laptop, mostly it will be very hot. If I put the laptop in the standby more for about 10 minutes, then it will become normal and I will not heat the fan sound. I am not playing any games in my laptop. But I used work with two or three applications simultaneously and also my browser window will be having multiple tabs always.This can be also a reason for that. Is it so?Thanks for the detailed clarification to my doubts.

As I am not having much experience with the BIOS set up and configuration, I have to call an expert only to check the settings, as you have mentioned. If I keep my hands on the hard disk while it is hot, I can not keep for more than 3 seconds. It is the abnormal heat and I have never experienced with any t others laptop so far. I think I need to change my working attitude and should avoid multitasking.From the previous response, it seems multitasking is also one of the reasons for over heating of the laptops.Thanks for the guidance.

So far I used to think the fan is running only when it makes a reasonable noise. Only after seeing the responses, I looked back of the my laptop and check for the run of fan. Still it is running, but at slower speed as you have mentioned.Thanks for the technical information. But friends are saying that there may be some problem with the hard disk itself and that's why it is getting that much of hot.But I don't have any other problem with the laptop except the overheating and system hang because of overhear. But I have to call a technician very soon.Thanks for your reply.

Mine is also working for more than 18-20 hours in a day. But the fan is running fast only for few times and then the system start to perform slowly.Then I need to keep the laptop in the standby mode for bout 10 minutes at least.Then only it is working fine for about one or one and half an hour.This is happening repeatedly.Still I believe some problems may be there in the hard disk as some of my friends are saying that the hard disk should not get such a heat.I have to call a technician it seems.Thanks for responding to this discussion.

If this the case, then there may be the problems in the heat sensing element in the system or there may be some settings to adjust the minimum temperature at which the fans are supposed to run. My fans are running only if the hard disk much hot or when I am working with more applications.If the problems are only with the settings, then there will not be any problem in the adjustments and no need of spending money. If some other problems are there, I have to call the technician I think.Thanks for your response.

The working environment of mine is neat and I will clean everything very often, at least twice in a day. But I did not see if there any blockage in the vetilation slots of the laptop and some of the members are saying that could also be one of the problems. As I am not familiar with the hardware, I have some hesitation to open the back of the laptop. It seems that I have to call a technician and ask him to check the laptop. But as the time is not permitting me to do so, so far I failed to do that. Now I have to do very soon.Thanks for your participation in this discussion.;

Some times, I used to work with the laptop by keeping it in my legs. But I can do so far more than 10 minutes. due to the overheat. But now I have the doubt of the ventilation slots might have been blocked by some external particles or dust. I should clean it first.Even after doing so, if the system gets over heat, then I need to call the technical person to look after that. Else my hard disk may fail at any moment and can cause more expenditure.Thanks for responding to this discussion.

I have one more lap top in my home in the same make(hp) and that is not getting that much of heat. I am not able to keep my hands for typing on the laptop continuously for more than 5 minutes.Then I have to get back my arms.That much of heat is produced and only for few minutes, the fan is running now and then.I can not even touch the back of the hard disk panel after working with the laptop fro about half an hour. Am I need to change the hard disk or the fan?confusing ..Only the technical person can decide this.Thanks for your response.

There are lot of possibilities for that also.Because, some of the keys are not working well,(on/off switch and media control switches) Also the battery is not getting the power continuously it seems.That's why its giving the back up power for 20 minutes or 40 minutes like that. If we try to change the board of the laptop, then they will charge too much and for that much of amount, we can buy one more laptop..Now I have to call the authorized person to check all these things.Thanks for your response.

YOur laptop is suffering from lots of problems. If you go to customer care of laptop then they will charge more than you expect. so here you can buy another laptop. Just take back up of your important files.If in your country repairing charge is more then it is better to buy new one. I am very grateful to you for your comment on my response. I like your type of attitude to give comment on response. Have a nice time.

Well there are two or three fans inside every one of your laptop. But the third and the second fan run only when the processor emits more heat, or in other words the processor is processing memory intensive operations that require a hell a lot of memory to stay alive. If the third or the second fan runs continuously, then i suggest that you check out your motherboard or your processor fan for any defects.

It seems only one fan is working now and then, But others may not be visible easily to our naked eyes.But ventilation slots have been given in two placed at the bottom of the laptop and only the area where the hard disk is positioned is getting much heat. I can not even type a single response without any break, as I can not keep my hands on the top of the laptop.That much of heat is produced in the left hand side of the laptop and some are saying that there may be some problems in the hard disk.I am very sad .How much am I need to spend for that? I am not sure also..Thanks for your response to your both.
