Dell Latitude E7440 :: Loud Buzzing Noises On Processing
Jan 15, 2014
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.
I have been looking online and getting mixed results regarding buzzing noises from ac power adapters. My old hp dv6000 laptop powerbrick did not make buzzing noises as loud as my new dv6-1235cl from costco.
I noticed that a lot of people now hear buzzing noises from their ac adapter. Then I came onto this website.

Is this a bunch of bs or are they for real?
I can hear the buzzing noise when I put my ac adapter on the table, but almost non existent when its on the ground. I want to know if this will be a fire safety hazard in the future? I dont want my house burning down even when this thing is plugged in.
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.
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)?
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.
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?
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?
Recently my laptop starts to make a high frequency whining noise, almost constantly and rarely stopped.
I tried to locate the component which the noise was originated from, I can only figure out it's somewhere below the memory module, but there is no moving component there, so my biggest suspect is the fan, because if I put my ear to the back of the laptop, except the whining I also heard very minor "clicking" noise.
Another weird thing is, this noise only starts after Windows is loaded, not in BIOS or during booting, although the fan was running at those times.
I've recently taken delivery of an E7240 with the FHD touch screen option. I am generally quite impressed with the laptop except for one thing, the touch screen buzzes. The sound is similar to a hard disk working, a bit random .. not a constant noise. The sound will immediately stop when I put a finger on the screen though which makes me think it's related to the touch screen itself.
Rebooting etc. makes no difference... shaking the laptop, smacking it (gently) etc. has no affect.....
I realise these laptops are new so perhaps there isn't much experience out there...
I have 130W(model DA130PE1-00) dell orginal PSU and dell e6540.
When i plug in PSU into my notebook, then i turn it on, and after windows loads, it starting to make strange noise. after it warm up to 30 deegres of celsius, it stops making it
I have noticed that loudness of the noise is inversly proportional to load and temperature. When PSU is cold and notebook is idling - it makes the strange noise. When PSU cold and noteboot is under moderate load - it stops making it. When PSU is warm (about 30 deegres of celsius) and is idling - i need to PSU at front of my ear.
The noise seems to coming from AC connector's side (Where PSU have connector for AC cable). PSU doesn't make this noise when i put it off from notebook.
Why PSU does make such noise? Why it is inversly proportional to temperature and load ? This is dangerous to me and my notebook ?
Exactly it looks like:
1. I turn on my notebook under AC, the PSU is making "click sound" till it become warmer.
2. After that there is buzzing sound, that is not as loud as clicking (i have to put ear at front of my PSU), and the buzzing sound is inversly proportional to load of the PSU.
I just picked up a e4200 with backlit keyboard and whenever the back light is turned on there is a noise (slight buzzing or hum) that can be heard. As soon as the back light turns off the sound goes away. It's kind of bugging me because you wouldn't think that the back light would add to the decibel level of the laptop..
Bought a latitude E6400 a few weeks ago. Every now and again a loud cracking noise can be heard somewhere around the left side of the keyboard. This happens very infrrequently, about 10 times since I have had it.
Before I ring Dell has anyone come across this before?
The noise is like a crack and then a smaller click Sounds like a small peice of plastic just broke or something.
The laptop could be sitting there doing nothing for 20 mins and then the noise happens.
My wife got this HP G60-120us notebook computer. It's about two years old now. I'm planning on getting her a new laptop so I can get this one. The only thing that I really do not like about this laptop is the freakin mouse button. It's so loud and clicks so loud as well. What I'm using now is my old Dell laptop and I love the mouse button so quiet and smooth unlike the HP. Is there anyway to make this sound quiet? Like open it up and spray some WD-40? J/K, is all HP's like this?
I got this 7720SE from woot 3 days ago and after i played metro2033 on day 2 problem came up.. before that the laptop was really quiet even though steaming its like silent mode . and you wont hear anything .
right now you can hear the fan sound even though i am not doing anything and when i try to open up some folders or software like Steam the scratchy sound ( not loud but annoying) came out ( the ones you hear from old computers.
i tried online support but they keep saying i have to call customer care because theres a "pending issue" with my account ...
I recently ordered a Vaio FW-490 CTO with an estimated ship date of 9/16, but the order has been processing since the day I ordered it. Also, today I recieved an email:
"We regret to inform you that all or part of your Sony Style order SW********* has been delayed.
In order to serve you better in the future, our warehouse system was shutdown tonight. Regrettably, we encountered problems with your order that prevented your order from being fulfilled in time for the shutdown. Unfortunately, we will be unable to ship your order until 9/18/2009."
Is it normal for it to be in processing this long, or should I call them to see the the "problems with my order" are?
It worked fine for a year but starting the second year, the sound card started to fail, and by that I mean that the sound sometimes works and sometimes it doesn't, but I solved this problem by buying an external sound card.
Two months ago I accidentally hit the laptop in the wall and after that incident the Graphics card can't process anything that requires high or medium graphics for example:
-When I play 720p videos the video runs very slow, it should be noted that I used to play 720p withouth any problem before the accident.
-The Windows Experience Index for Graphics went from 3.4 to 2.0 after the accident.
-Games that used to run at 30-40 FPS, now run at 2 - 3 FPS max.
- Windows AERO runs very slow now, so I if I want to use windows I have to run Windows Classic theme.
Things I've done:
1) Format my PC and tried different OSs XP, 7. 2) Flash the BIOS. 3) Change the Hard Drive with another one. 4) Change the RAM. None of these things worked.
Does anyone know what might be causing this problem?
I don't know what happened, but my laptop's not working.
I was using my laptop as a desktop computer (no battery) when I accidentally switched the switch off. After switching it on, I tried to turn on my laptop and the first thing I noticed was the blank screen. Then the power turned off, and then turned on again. The fan is working, but nothing else is. I don't hear or notice any processing, so I'm pretty sure nothing's working right except for the fan and the lights indicating that it's on.
I tried to reset the laptop by disconnecting it from power and then turning it back on after 30 seconds - but no luck.
I did a search and read various thread on the older Sony Vaio Z battery life. However, these are all in the year 2008 and pre Windows 7.
Vaio Z battery life tests
Vaio Z reviewers getting 9hr battery life!
I do a fair bit of transatlantic flights. So I'd like to know what battery life I can get with the Sony Z890, Windows 7, with all processes such as WIFI, Bluetooth etc turned off and being used in word processing and reading mode using the integrated graphics, with brightness at 50%. SLOW is fine as word processing is easy.
Anyone has a sense of the battery life I should get?
What if I turn on WIFI and use it as a netbook for surfing at airports?
I can't seem to find a recent discussion on battery life. The 2008 threads has a huge disparity with some people claiming something like 9 hours doing basic stuff! Hard to believe but thought I'd check with you guys.
