Dell Latitude E6440 :: Fan Runs Constantly
Mar 5, 2014
I just got a new Latitude E6440. Overall I love the system, but when it is docked / on AC power, I have noticed that I can almost constantly hear the fan. Right now my CPU is only at 6% but I can hear the fan running. Is that just normal behavior with this system? Does it just have a louder fan that runs more often? I just upgraded from an E6410 and I don't recall ever hearing the fan.
I am running Windows 8.1 Pro, and it is a brand-new install. I ran diagnostics and did not find any issues.

The fan on my laptop runs constantly. The noise is very annoying. I have been having this problem for 6months plus. In reading previous posts, upgrading teh BIOS seemed to resolve the problem for a while, but it is happening again now. The fan runs from the second I turn the computer on. I am running the A02 BIOS. I just ran diagnostics and the fan test passed - speeds were 4500, 4500, 4000. current CPU temps ranged from 68-71. What else can I do?

In the last two weeks or so, the fan on my Studio 15 (1535) has been running continuosly. Even when it's under little/no load for extended periods of time, the fan stays on at higher-than-low-speed (from the sound)?
I've had it for about four months and this wasn't an issue until very recently. I have updated the BIOS twice (A02 to A03, then A03 to A06) and wonder if the most recent update was the culprit. I skipped A05 initially, but a few days ago I re-flashed using A05 to see if that might fix the issue- no dice! I'm debating whether I should go back to A03 and see if that does the trick?
But I don't want to keep arbitrarily flashing the BIOS over and over if there's no chance of it fixing the fan issue.
Anyone else have similar issues with the fan running constantly? Any suggestions on how to fix or, at least, mitigate the problem?
FYI- I always use the laptop on a flat, hard surface (desk or wooden lap-desk) to allow proper heat dissipation. I have also tried elevating the back of the system by 1/2-inch or so to improve airflow- NADA!

I just bought a N7010 and the cooling fan runs constantly. It keeps the laptop cool, but I don't think it is supposed to run constantly. Is this a firmware upgrade or something else?

When I power on, after about 5-6 minutes the fan (I assume the CPU fan) kicks in. However, it then seems to remain on constantly until the laptop is turned off, even if I'm only idling. This is slightly annoying, not just because of the noise, but also it seems to have quite a noticeable effect on the battery life.
I have installed SpeedFan to keep track of the CPU temp and it seems that the fan kicks in initally when the core temps reach about 35 C, but then the fan does not switch off, even when temps drop back down to 25/26 C, which seems very cool.
On every other laptop I have used (none of which were Acers), the CPU fan only comes on now and again, as and when it is needed.
So, is this normal behaviour or is there possibly a fault with the fan control mechanism ? If so I will consider taking back to the retailer for an exchange.

I just bought a new Latitude E6440 Notebook with an i5-4300M and SSD using it with Linux. I noticed that the fan was continuously spinning until I installed the graphics driver from ATI and switched to the Intel GPU.
Now it is off at the beginning but i kicks in when the CPU temperature reaches ~42C relatively loud and cools down the CPU to about 38C. This behavior is very annoying because the fan is switching on and off every few minutes.
I tried to manage the fan via i8k module and fancontrol but there seems to be some control at BIOS level as my settings are always being overridden.Is it possible to change the default cooling behavior of disable the BIOS thermal control completely so I can manage it in software? I tried the Shift+FN+15324 trick but FN+R does not bring up the menu for me. There is also no option in the BIOS where I can change the fan settings. I am running the latest BIOS A02.Is there any other trick to manage/disable BIOS fan-control or is it possible to include the setting in the next BIOS release?

My keyboardd generates double letters (I'm leaving them in as I type to show what II mean). I've searched this forum for similar probleems and have already done the following:
Updated BIOS
Installed/uupdated toouchpad ddriver and input ddriver
Installed touchfreeeze
Unchecked the keyboard driver in device manager andd restarted the computer
None of those steps has solved the problem.

The HDD LED is constantly blinking with one second frequency. I'm using WIN XP, this blinking can not be seen in BIOS, but I can see it with a Live XP, and it's also blinking when XP install starts, but there are not any processes.
Because of the mentioned reasons, this could not be because of indexing, or pagefile (additionally I have tried to turn them off, and blinking remained)..
I've reported this issue to Dell, and the HDD was replaced, but I still can experience the blinking., if you have experienced an issu like this.

I have a problem with my Latitude E6430 i7-3720QM upgraded to Windows 8,, Bios A09, 8 core...Fan is constantly running and drying the battery out. Tem range between 60-70C. All tests from Dell webpage passed successfully. Tests from Intel Diagnostic tools passed. However, fun is always running, lap top is warm and battery goes down very quickly, in an hour. Under windows 7 it used to last much longer. I even did a clean install of Windows 8 and the problem persists

So I've been having some trouble for a while with this thing, when it goes into standby or is starting up often it will do this thing where no lights come on at all, including the power button, all I hear is the fan whirl at top speed. That's it.
Sometimes if I let it sit for a day and try it again, it boots no problem. Sometimes I have to remove the battery, press Fn for a while, and then unplug power and it will boot. Sometimes removing the Flee power by holding down the power button after everything, ac adapter and battery, are removed. But this time nothing is working.
This thing is not even two years old, and I am getting further and further discouraged by the Dell brand. I have always had great sucess with my work computer's being Dell so thought I would go that route for my personal. But alas I've read numerous things with this type of laptop having fan/video issues though nothing sounds like my problem.
All it does is spin it's fan when the power button is pressed. It got into this state when the screen was closed and it was forced into standby. It would not come out of standby, and would not shutdown by holding the power button. Had to removed battery and ac to get it to shut down. It has yet to come back.

so i've got a dv5t. i have the notebook raised up 6 inches in the back while on a desk, and i've also got it undervolted (down to 1.0250V on the 9x actually) and this machine always runs hot. hotter while in games (which makes sense.) but even while just browsing the net, it gets hot.

my dv5t ALWAYS runs too hot. atm with just normal web browsing and listening to music my cores and GPU are at 80C and this is WITH an antec laptop cooler
my specs are P8600, 3gb ram, 9600GT, 320gb 7200rpm
just talked to several friends with gaming laptops and macbook pros...no one runs higher than 70C with just normal usage and they don't use a cooler or anything.

Long time no see! I'm about to grab a Inspiron 1521 for $100, the problem is in the title. Run's fine, for a half an hour then shuts off.
My assumption is the maximum problems could be:
- Fans not working, resulting in an overheating: hence shutdown at max temp.
- Heatsinks or thermal compound issues, resulting in an overheating: hence shutdown at max temp.
- Rare possibility that it has a cold solder somewhere located in the mobo: hence shutdown after 30 minutes of running, generated heat build up .....

I have upgraded my laptop from 4GB to 12GB (4+8). After the upgrade, the laptop boots and runs very very slowly.My laptop came with 4GB ram 1600 single stick. I upgraded the RAM by adding another stick of 8GB same bus and same manufacturer. The BIOS shows the total memory as 2288MB instead of 12288MB. Windows detects total RAM of 12GB but boots and runs very slowly.I have updated the BIOS from A06 to A07 trying to resolve the problem but with no luck.When installing each RAM stick alone (4gb or 8gb), everything works fine, but the issue comes back again when both sticks are mounted together even when switching the places on the sockets.

i have a HP DV9623cl and it will only run off the battery. When the adapter is plugged in Vista recognizes it and will display that it is charging. But as time goes on the battery runs out and the laptop turns off. It will not even turn on when plugged in.
Things i have check;
i have taken it apart and see no signs of damage anywhere near the power connector or the battery.
i have tried swapping out the power connector board with no success.
swapped power adapters.
swapped batteries.
updated the bios to the newest version.
Ran a linux live cd to see if it was windows.

my Acer 8204 laptop runs in the bios with just the battery, but the moment it tries to load up Windows it shuts itself off
I tested it running on bios and it lasted the full 2hrs of battery
But
When running through Windows startup it has the splash screen and then
It switches itself off automatically, with Power in it runs perfectly fine...

I have changed my dell studio 1535 motherboard after ordering a refurbished one from dell. When reconnecting all the parts, everything worked well except the control media button <Previous Track> which was lighting up by itself from time to time.
I unplugged the media control panel, plugged it up again. This time the media panel is lighting up intermittently and the laptop cooler is at maximum. Unplugged again, a cable pin was short circuited and got broken in the process :(.
Fixed the cable, now the media control panel is completely down and the cooler runs at maximum speed. Removing the media panel fixes the cooler issue.
As I am not an expert into this, I was wondering if changing the panel will fix my problem or the faulty connection could have broken the motherboard control panel circuit.
PS. When running diagnostic via F12 key, no faulty issue is detected.

My fan is not working properly, in fact it only runs for few seconds at booting and then never again.
My cores get about 70°C and higher (with only Skype and Chrome on), so I'm forced to use external fan to by able to work.
I found this problem when I was working and then my notebook suddenly shutdown a I wasn't able to turn it on for a while. Then I grabed it and I almost get 3rd degree burns.
Two noisy external fans, that I have to use to keep core under 70°....

Bought a VGN-FW26 over the weekend (ATI HD3650, 2.40 Core Duo, 4GB RAM, Vista Home Premium).
On bootup, tried out a few games (mainly Fallout 3, Rainbow Six Las Vegas). Everything was running smooth, especially Rainbow Six at full resolution). This is with all the factory-included bloatware running.
I got annoyed at the bloatware, so performed a semi-clean install of Vista (ie. reformatted comp, reinstalled Vista, cancelled the installation process for the Sony programs ... then manually installed a selected number of programs using the VAIO Recovery Centre. These programs consisted several of the essentials from the programs list, and ALL the drivers).
Now, when I run the for-mentioned games, there's a noticeable increased lag for those games. I have even removed optimised Vista by disabling some unnecessary services, as well as made sure there are no unnecessary background programs running (e.g. McAfee)
In addition, I haven't been able to install the Catalyst Control Center, the VAIO Recovery Center only lets me install the ATI driver (I was thinking perhaps the lag in games is because my graphics card is running in a "maximise batteries" mode?) Is there anyway I can extract the Catalyst Control Center install from the recovery disks/drive?
