Laptop + fan keeps running, why?

Question

I have a paw with a centrino 1.4 M proc, when I have a paw on my knees, the fan turns on from time to time, but it is mainly on the desk. and then it ...

In the power settings, you probably have the maximum processor performance set (selected power scheme: Always On). As a result, the processor works at maximum speed, quickly depletes the batteries and just needs cooling with a fan. It goes on all the time (with small interruptions) to prevent overheating of the processor.

And on the desk, the situation can worsen because there is no adequate ventilation under the laptop (exchange of warm air for cool air). I solved this problem by buying a cooling stand and changing the power settings to: portable / laptop

Well, your settings are good. There may also be such reasons:

1. If it is an Acer laptop, you can have the option of cooling the processor all the time in the Acer PM settings

2. The graphics card heats up and the heat also reaches the CPU turning on the fan. You can lower its performance, thus reducing the heat generation.

As a good solution, I recommend a laptop cooling stand. It is very quiet, light and efficient.

PS You can also check if the situation will repeat itself when you leave a 3-4 cm gap between the laptop and the desk by placing the back of the laptop, for example on a book.

It is well known that the laptop heats up mercilessly (regardless of the type of processor). However, it is also known that the most heating elements are the processor, graphics card, wi-fi card and memory. To prevent this, you can either reduce the efficiency of computer components so that they consume less electricity and heat less at the same time, or use something, it will lose the temperature in a faster and quieter way ... As you can see what I said - raising the laptop or increasing the access of "fresh", cool air to the bottom of the housing gives the desired effects.

As for the warranty, I think that it makes no sense to send the computer because most likely it does not state anything and additionally may charge you with shipping costs and expertise that can amount to several hundred zlotys (!!). I would recommend a cheaper solution - buying a cooling stand, eg CoolerMaster CoolPad or Vantec LapCool 2 or 3.

i.e. I have a portable / Laptop set up, but I set myself to only turn off the monitor when it is powered after 3 minutes and on battery after 2 minutes.
Set him something else, for example, suspend the system or turn off the hard drives, does the frequent use of these options harm something, probably in this case the HDD?

well, I just made the last option and something extra. I can describe everything from the beginning.

I put the laptop on the book and I would still be walking 5 cm above the ground, the windmill would not slow down or accelerate. So I took the fan for cooling and I turned it on and the cooling in the paw turned off, but later, as I put it on the desk, it turned on again after a dozen or so minutes.

I called the service and they told me that if I wanted to, I could complain about the paw, in total, nothing for it and it is convenient because I have a door to door guarantee and the guy said that whether I would advertise it depends on my convenience because walking the fan does not bother the laptop in any way ( I knew it myself

) but only the noise can disturb me. And so now I'm wondering whether to send back or not, is everything okay?

next to the prock, there is a wifi card, and as you know, they all get hotter and the processor may not be able to drop the temperature quite quickly, although it's a bit strange.

It is different today. I got up in the morning, put the book under my paw, turned it on. After a dozen or so minutes, the windmill turned on as standard, then I was not working on the computer, some 15 minutes, the windmill came out, apparently when he works all the time on his desk and under the bed, the prince needs a lot of time to lose this temperature. So I guess everything's alright ?!

I mean, the costs will not burden me because I talked to the guy, there is a guarantee, but when you say that there is no point in sending it.
Tell me what you think about such energy saving options as turning off the hard drives every 3 minutes as well as running on the battery and suspending the system, e.g. every 5 minutes, does it have any effect on the components, because I will use it quite often.

This stand is quite expensive, because 160z, but I will think about it.

First of all, the services are always charged with costs in the event of not finding a defect (or for the first time free of charge).

As for turning off disks, the matter is rather poor - the more times it will be turned off and on, the shorter its life will be. Better to roll around and use a little electricity than to be so tired.

As for the stand, you can already buy Vantec LapCool 3 for PLN 75 with free shipping - at least I bought it like that :D

PS I currently have the "portable / laptop" option and turn off any disabling of the monitor, disks, etc. I save the disk, the fluorescent lamp and that most of the time it runs on electricity from the socket, it is not a problem.

Could you give me the bearing where I could buy this stand, do you have photos of it?

adamdn · Answer

Of course I can - contact me on priva and I will give you the contact details.

As for photos, it will be hard because the laptop is connected to 50 different devices and to disconnect them I would have to lose an hour

Therefore, I enclose 1 photo from the website. The other two are my photos of the box (front + back) which I managed to find.
