Dell Latitude E7440 :: Fan Is Always On High And Never Stop Even CPU Idle
May 15, 2014
I just got a refurbished E7440. Before booting into an OS (e.g. staying in BIOS or at the boot menu), and after booting into Ubuntu, the fan is always on high and never stop (even when the CPU is idle at 40 degree C)). I also have an E6420 and an E6440, have never seen this behavior on them.
I see both BIOS A06 and A07 has "thermal control" listed as enhancement. Updated the BIOS to A06, A07, then A08, still have the same problem in all of them.
Is this expected for all E7440s or just mine? What can I do to make the fan be "on-demand" (without using Windows)?

i purchased one compaq cq45-137tx in december. I guess it' similar to the dv4t models marketed in other countries.
model details
there are couple of temperature issues with this lappy ( ambient temp 25-30C):
1. at idle ( just media player or maybe a pdf file open), the cpu temp is at 43C, northbridge always above 50, gpu always above 55.hd also tends to operate at 45-48C. this is inspite of the fact that i am running this thing with no vents blocked ..and in fact the RAM, cmos battery and hd covers removed to allow better air circulation.
2. at normal load ( game like burnout paradise, with utor going on in background), cpu tends to reach 60 C, gpu at 80 C , northbridge at 70C and hd at 60 C.
3. cpu temp never seem to change really. tried using various s/w' like realtemp ( shows 28 C for gpu..which i dont think is feasible). only when i reboot after a high load session, the s/w' show higher temperatures ( and the notebook shows erratic behavior with display artifacts!).
4. the only fan in the machine never appears to speed up or down. i don't have an issue with the noise, as long as it helps this thing run cooler.......

I bought my G505s in August 2013 and I'm only noticing now that it's been running pretty hot.I've been using several different programs to try to see and compare the temperatures of the quad core CPUs. I've also looked in many different fourm communities and have found this is not at all like the common overheating problems with the G505s. Others have experienced other heating problems when they play games, as their cores go to around 70C to 80C
"How so," you ask?Details and actions I've taken:
1. My temperatures soar to above 80C each when idle, and over 100 when doing light work.
2. BIOS and drivers have all been updated to the latest versions available for Windows 8.1 as per the Lenovo website.
3. I have never played games on the laptop, so I know the overheating is not because something related to that.
4. I cleaned my computer yesterday, although there was hardly any dust build up.
My temperature readings come from speccy, and hwmonitor.

So I have been talking to the customer care representatives of Dell and they keep giving me different answers for my questions. So I was hoping I could have a more constructive discussion here without being put on hold for hours -_-
1. My E7440 came with a SSD. Can I add a second internal HDD along with the the SSD?
2. If yes, would buying it from a different vendor (say Amazon) and installing it myself void my warranty?

I just purchased a new E7440 recently and most of the time, it will not shut down- the power light stays light, but display is off and the HDD light blinks every few seconds. If I leave it, it hibernates eventually but only shuts down when I actually hold down the power key.
The same thing happens if I restart instead of shut down.

In Window's control panel, Biometric Devices shows me that the drivers are ok "Allow biometric devices with windows" is flagged. With Broadcom FMA I can easly enroll my fingerprints
Everything looks good but at this point there's no way to use my fingerprints to logon with Win7 pro.
In control panel / programs I can see installed: Dell Data Protection | Security Tools and Dell Data Protection | Security Tools Authentication but I can't find out any program to manage my fingerprinters.
I tried almost everything, installing/uninstalling drivers, softwares and all this didn't work. I suppose that I should find a program or something that allows me to associate the enrolled fingerprints to my account.
I even tried to use Dell My Downloads (with Internet Explorer) but I cannot because during the installation I had the message Service Tag Number not supported.
Windows logon shows me, next to my account and security card, another "account" fingerprints, I even tried to login with this but I received the message "Fingerprint not verified" (obviously because they are not associated to any account)....

Though in all adverts it boasts about strong encryption options, I could not find any way of encrypting the disk other than Windows Bitlocker.
In the Dell Data Protection Console, but there are no options in the Encryption Tab. I even downloaded directly from Dell product site DDP Encryption software (650 Mb !) but in the installation, personal installation option is disabled asking for only Enterprise installation which requires some kind of a server.

I'm experiencing a problem with multiple Latitude E7440 laptops.
When I undock from a port replicator, the laptop screen goes black. The screen never returns to a usable state. I must turn off the laptop manually and power back on. This is not occurring 100% of the time but is occurring fairly often. I'm running the latest drivers and bios update.

I need to check the normal operating temperature for the Dell Latitude E7440. My fan is constantly on and the air coming out the side vent is extremely hot. I have installed a temperature app and with basic use (windows 8.1 and 2 or 3 apps open) the core 0 and core 1 of the processor are running between 85 and 90 degrees Celsius. When plugged into power, the fan is permanently on high speed. I don't know if this is normal. I dont understand why it is getting so hot, i have the i7, 8GB, 256GB SSD, so literally no moving parts to generate heat. My battery (47Wh) drains very quickly as well, 2 1/2 hours max.

2 days ago I was given a new work laptop - the E7440 (its brand new).
Straight away I noticed some loud buzzing noises which a fellow colleague said was the fan. It's quite annoying. I soon noticed however when my laptop was idle these noises would stop, and when I clicked they would start again. Whenever I ask the Laptop to do anything these noises start up, and considering im active on the machine all day.
There are high pitched, buzzing noises. And as mentioned are aligned to when the laptop is processing something. They also make sounds when I scroll the mouse for example.

Received a new Latitude E7440 today, and I like having the option of a pointing stick and a trackpad depending on what I'm doing, however the pointing stick apparently also can be "clicked" instead of using the dedicated buttons... this is annoying to say the least.
When I'm moving the mouse pointer with the pointing stick, if I press a little too hard it thinks I'm trying to do a click/drag.
I can operate the dedicated buttons just fine, so is there some way to disable this pressure-sensitive click feature on the pointing stick? Otherwise I'll have to disable the stick entirely as it's more annoying that having somebody randomly clicking the mouse buttons while you're trying to work...

I've been having issues with this with this utility either not connecting upon resuming my laptop or even from a fresh start. I visit many offices at I am the IT manger and all the connections are saved in profiles but despite them being saved they won't connect even when I try to connect manually. The only way to get the adapter to connect is to right click Proset running in the tray and click "reset proset". Even now while typing this I am connected via wifi but the proset icon shows "connecting"
I've tried updating the wifi adapter drivers from Dell and Intel directly and also completely removed the drivers and re-installed them but I am still having the same issue.

I'm attempting to enable BitLocker on a Latitude E7440 running Windows 8.1. The system is in UEFI mode with Secure Boot enabled, so I'd like to use Secure Boot for integrity validation. I have the appropriate GPO set, but if I try to enable the TPM protector, I get the following warning event in the BitLocker-API management event log:
BitLocker cannot use Secure Boot for integrity because the expected TCG Log entry for variable 'SecureBoot' is missing or invalid.
This is immediately followed by:
BitLocker determined that the TCG log is invalid for use of Secure Boot. The filtered TCG log for PCR[7] is included in this event.
The system therefore ends up configured with a regular platform validation profile instead of using Secure Boot. Is this a problem with the firmware on the Atmel TPM on the system, or is it something else?

My E7440 is new and shipped with Ubuntu (12.04), it has the A11 firmware version
key presses on the laptop's keyboard are randomly repeated making it usable without an external keyboard. [URL]....
Is there fix for this coming in a firmware update and/or is Dell working on a patch for the linux kernel?

I am new in Windows 8 and i wanted to install either fedora or Ubuntu 12.10 in WIndows 8 64 bit. However, under Advanced options in the General settings, i don't see the UEFI settings tile which shows the UEFI firmware settings so that i can disable secure boot. What should I do, or which other way should I do so as I can be able to dual boot?

I am experiencing an issue from the usage of the pointing stick (I have gotten accustomed to it) where the cursor would drift slightly about 3-4cm before it stops when I let go of the pointing stick. It occurs maybe about 5-10 times on a working day. The funny part is if I continue to move the pointing stick and letting go just right before it finished drifting, it would continue to drift perpetually until I allow it to finish drifting i.e usually drifts 3-4cm away from the pointed area. It causes me inconvenience whenever im dragging an icon or a browser around and it can get pretty annoying.

I've had my laptop for a little bit under 2 months, so these are the things I have noticed.
Issue number 1: When you plug in the power cord into the computer, the screen freezes on what it is currently on. I noticed this issue because occasionally when I plug in my power cord, and try to use the mousepad to select something, the mouse pointer is gone! I have to unplug-replug the power cable to get the mouse pointer to show again. It seems to have to do with the screen
Issue number 2: when I carry my E7440 around in my bad, or have it shut for long periods of time >3 hours (I just simply close the lid), the computer will SHUT DOWN. The thing will shut down completly, even though I simply closed the lid! At first I thought it was just going into hibernate, so I disabled hibernate in my power settings. But nope, even when the computer is asleep, it will occasionally shut it self down for no reason at all.
Just now, I closed the lid on my laptop, and put in in my bag, then walked to my office about 10 minutes away. When I sat down at my desk and opened my laptop, to my surprise, it had shut down by itself! All of my open windows, browsers, and applications were closed, and upon opening chrome and microsoft word, I was greeted by "your browser did not shut down correctly" and "microsoft word has recovered files". This points to the conclusion that it was not hibernates fault, but instead a issue with the laptop itself shutting down when it is put in sleep. This issue needs to be rectified immediately if it is a widespread issue.
Issue number three: When the computer comes back from hibernate or sleep, the computer is very very sluggish, even when plugged in. It is sluggish forever, OR until the power plan is set from whatever it is to "high performance". upon switching to the previous powerplan from high performance, the swiftness of the system is restored. This indicates to me that the system is throttling itself after it resumes from hibernation, why. This needs to be fixed; many people (myself included) just thought that the system itself was slow and underpowered, not realizing that it was just throttling itself when it emerged from sleep or hibernate.

I was using my laptop the other day and it froze up. Then it shut down by itself. When I tried booting it back up, it says "No bootable devices found" and gives me the options to press F1, F2 or F5 for retrying, setup utility and diagnostics. I ran the diagnostics and it says "All tests passed". The SSD also seems to be recognized as it shows it in the "configuration" tab in diagnostics. I have also tried taking the msata SSD from the 2.5" bay and moving it to the msata slot. Rebooted but shows the same thing. Is this a known issue and is there a fix for this?

We have a problem of keyboard with many Dell Latitude e3540 . Some keys randomly stop responding . We have updated the firmware to version A08 but unable to fix it. Also reinstall the driver keyboard controller with the same result .
The only thing that can solve the problem was momentarily disconnecting and reconnecting the keyboard . Likewise, the problem usually returns . The local support Dell keyboards we changed several times but the problem persisted.

I ordered new E6500 that came with Vista on it and I wiped that and have installed XP Pro SP2 on the machine. I have followed the guide on this page and installed everything in the correct order. The only thing that didn't install was the dial-up modem. It errored out and said "No MODEM device was found". Typically on the Latitude laptops I seem to remember installing the modem driver and it taking care of this entry in the device manager, but not this time.
There is a dial-up modem on the laptop and this is the only device that looks to not be installed. There is no webcam, WAN modem, or anything else like that.
Has problem with installing XP onto a E6500? Is the installer for the modem driver just bad or is there possibly something else going on.

I thought sleep mode only occured when you did not touch the mouse or keyboard for a specific period of time but my new ultrabook is dimming and locking me out while I am typing. I have to push the blinking power button and then I have the blue screen with CTRL+ALT+DELETE (work laptop).I cannot find any sleep mode settings and perhaps.

My dell xps m1710 temps at idle are
CPu 54C To 58C
GPU 54C To 58C
Is that okay?
The bottom of the computer is hot to the touch and the fans are blowing out hot air. I cleaned all fans and heat sink vents. also re applied all thermal paste on the cpu and gpu. Im concerned because my motherboard and gpu were just replaced yesterday for heat issues i believe. havent figured out if the heat was the cause or not. the temps were the same as there now with the new motherboard and gpu .....

I have a Dell XPS 1340, P8700, 9500M GS.
I noticed that when idle the temperature slowly goes up to 65C, then the fan kicks in, lowers it to 45 and stops. The temperature goes up again and in about 2 minutes it is already 65 again.
The process repeats indefinitely.

For the past few days, I woke up to my laptop's fan rather loud spinning. I noticed that my computer was constantly at 100% CPU usage even with like literally no processes opened, and it's idling ~50C.
It's to the point where moving my mouse across the screen lags, the pointer jumps from one spot to another.
I'm not really sure what the problem is, I ran AVG with no problem, and I don't remember doing anything to my computer in the past few days that would be considered abnormal...in fact, the only thing I did do was try to use a screensaver for the first time ever, but I turned it off with no difference,

i was reading a few other posts about idle temps of the GPU in the XPS 1530 and my temps are way above what everyone else is getting.
I have an idle GPU temp of approx 80-88 degrees celsius. I mean i could maybe expect that under a heavy load, but an idle temp??? The fan seems to be on all the time.

While in use, the XPS 12 is usually fairly cool and quiet through normal operation. It spins up if in heavy use of course. This is whether on AC or battery power.
However, if the machine sits there and goes to idle, the fan spins up like crazy and the bottom warms up to. This is for hours and hours at a time - often if I leave the machine at night and come back in the morning this is the case.
I thought it might be some process that starts running when the machine is idle and away, but if I leave Task Manager open there isn't any disk or CPU activity that would indicate that happening.

I just got the xps 1640 today and I'm very distracted by the loud system fan. It's audible all the time even when the computer is idle. I haven't been doing anything intensive on my computer either. The fan starts as soon as windows loads and never stops. I know this laptop has heat issues but I checked the core temp and it is only between 38-45degrees C. I know the fan can get louder under load, this is what I would describe as idle but still, it seems way too loud. It was raining earlier and I could hear the fan over the sound of raindrops hitting my roof. It's getting unbearable!!
Has anyone had the same experience? Or more importantly does anyone have a way to reduce the speed of the fan slighty? Speedfan doesn't seem to support my motherboard so I can't do it there.
System:
P8600 2.4ghz
4gb ram
320GB (7,200rpm) WD HD
