The fan runs super fast. HP Compaq dc5100 SFF
These days HP Compaq dc5100 SFF - or fans have aired the apparently fast fan speed.
Was full of dust (to the point of blocking the absorption on the front fan)
Used an AIR CAN blow the dust out with the lid open. We also had a blip of brief power in the last days - caused a stop down. And we have updated some business software. Has been restarted.
We have 3 more of the same model which are OK
Thanks for any help
The SFF dc5100 is notorious for bad capacitors on the motherboard. I had one where the fan ran at top speed all the time. There was a swollen capacitor located at the end of the PCI 1 connector. It seems C469. It's a 6.3 volt 1000uF cap. I replaced the capacitor and that fixes the problem. To keep the computer cool lengthens the service life of capacitors. It is wise of the dust periodically in order to cooling air flows. How always, once a capacitor going bad, the only solution is to replace it. A burned capacitor will be inflated. The flat top normally will be curved upwards and, possibly, a leak of a crispy Brown material.

Battery Tecra M11-130 with not power and the fan runs constantly
We are having a problem with the battery on one of our laptops. When left for an hour or two the laptop turns off because the battery is dead. We have mounted a battery new but still only get about 1.5 hours.
In addition, the fan runs continuously. I looked at the PC Healthcheck software which shows as follows:
* Power *.
Other costs 14%
40% of energy consumption system
Good battery
* Temperature and fan *.
CPU temperature 67%
System internal temperature 56%
88% fan speedI would like suggestions.
> We have mounted a battery new but still only get about 1.5 hours.
1.5 hours is a common value, you should consider that dough working time depends on its portable use.
Battery needed to dump a lot faster if the CPU would be stressed out a lot in your case, that something could run in the background, lose power CPU performance and the dough.
In addition, you said that the fan runs constantly this could discharge the battery too.
Therefore, it would be interesting to know what process emphasizes the central unit.Start the Task Manager and check the processes tab. In the CPU column, you can find the process that emphasizes the central unit.
In addition, to change the settings for the CPU performance and cooling of the activities in the options of Win 7 powers that would help to increase the performance of the battery.

Qosmio F30-112: cooling fan runs very fast
Hello
I want someone ask them, my computer laptop qosmio F30 - 112 recently whenever I start my computer, I heard that the cooling fan runs very fast (I mean) it wasn't stop differently than before his execution smooth only I heard when I play games but not continuous, then after that my computer now running slow.
Can someone help me what im going to do?
Thanks: rtmasagca
Hello
F30 is a little older series laptop I think about 3 years or more... you cleaned the cooling modules in the meantime?
I think there is a lot of dust and debris inside the laptop and I think that keeps air from traffic and therefore fans run faster.
Try the compressed air jet that should help to remove dust and debris.Good luck

Note that all computers become slower over time even in the normal conditions of use. Generally, the experienced users erasing the hard drive and do a clean install from scratch at least once a year or every time that the installation of a major upgrade of the OS. Well sure doing so also means that you need to maintain regular and several backups.
Add more RAM or reduce the number of simultaneously executed from applications and utilities. Remove unnecessary software such as anti-malware and that promises to clean your Mac.

xinetd is running at 83% or more 24 x 7 devours battery in 2 hours or less and making the fan run all the time. I am connected to a bug report, and it turns out that it was a duplicate because someone else had the same problem. However, I have no access to the other bug report or find anything either in the discussion forums or online. Anyone experience this problem?
Hello gorgonzola1111,
I doubt that someone else has this problem because xinetd does not part of macOS. Have you installed it from a package of "ports" 3rd party?

the fan runs full speed at the beginning upward
HP Pavilion p6-2037cb bought 19/01/12. Windows 7. There is no error message.
When I turn on the computer after it has stopped all night the fan running at full speed. This has happened several times in the first month. The first time, he stopped himself after a few minutes. Then I learned to stop it by restarting the computer simply. It still works, but what was once happen one or two times a month, happened twice in two days then you worry I the problem worsens.
It never happens when I use the computer because I don't do anything that requires a lot of cpu or causes a warm-up. I just surf the web and send e-mail. No games or videos or TV.
If it's a problem of connection fan I would like to know the nearest repair service. I would rather that ship it. But I can't find a list of authorized warranty repair service center. I followed the links on HP Support Assistant but got sent to a site that does not list the pavilions.
I need to know why the fan runs full speed at first upward and where to repair close to where I live.
Hello mpw101,
It seems that there is some confusion about the products of your receipt and how he explained. I have passed your thread to appropriate to review team. Someone must be in contact with you shortly so that you can discuss your experience of HP customer care.

Satellite Pro S500 - 11 c is suspended and the fan runs at full
Hi people,
I am experiancing a problem with my Satellite Pro S500 - 11 c where close unexpectedly, it crashes and the fan runs at full speed. Discount to zero is my only option and this resulted in the windows having to retrieve a few times so I'm fearing one requiring a major reconstruction after a deadlock of the future. Until now this issue has occurred only when you use a wireless USB mobile of 3G or internet teathering via USB with my iphone 3G. Using another USB port did not help.
If someone has encountered this problem and have a fix? No help from Toshiba?
Best regards
Andrew
Hmmmm... What to say. Problem is that you use third party hardware and software and some conflicts are possible. The question is: who can help you with this?
In general you should talk to your ISP provider at first to see what they will say about all this.Have you ever talked with them?

HP compaq dc5100 sff: loss of internet connection on desktop after installing windows 10

Ok.
The only suggestion I can offer would be to install the latest driver ethernet directly from BCM and see if it works.
I think you need the first driver on the list for 32 bit.

You will need to manually install the driver for the adapter ethernet BCM in the Device Manager, as the file contains only the driver files and no setup.exe file.

Satellite A505-S6973 is overheating and the fan runs often
I hate doing this, but it seems to me have encountered another problem that I was responsible for research and reading hoping to correct me. I currently own a Satellite series laptop PC with an Intel Cor 2 Duo T6500 processor 2.1Ghz.
I followed my system for performance issues andi who have noticed for some time (not sure when) has significantly increased the temperature on my system. I'm seeing from my PC Health Monitor my processors running at 59% temperature and fan speed is at 78% and yet when I place my hand near the cooling fins on the side of my laptop, I can barely feel any breeze, but a colleague of mine has a vostro and fan feels like it will run on amendments.
If there is nothing that can be done, I would be very happy, I'm afraid of losing my system because of something simple that cause overheating.
NB. I noticed that at the same time different users posted threads indicating that after updating he BIOS they have known overheating problems. If this is the cause of anywhere near it please help.
Hello
Just a question;
The unit automatically shut?If this is not the case then you cannot talk about overheating only because the temperature has risen to a higher level.
The temperature of the laptop up and down and it depends on the use of the laptop.
The cooling fans would go faster too if the temperature would be going upward.It's not unusual and it s a common behavior of mobile.
As I said; the laptop would be down automatically stops if the temperature would be too high! If this isn't the case, then you should not be worried about the temperature.

I've updated to the latest version of the BIOS.
