Dell Latitude E5440 :: CPU Spikes Every 9 Seconds (no Apps Open Or Network Traffic)
Jan 4, 2015
Having done a lot of monitoring of my Latitude E5440 because of fan issues I spotted large CPU spikes every 9 seconds (no apps open or network traffic):
I can see it's caused by a group of "DcomLaunch" services. My old laptop with same OS, software, Anti-Virus (Avast) does not show these spikes.
Looking at similar problems reported on the net it was down to a third-party service/driver or malware but I have done a full scan and it still occurs in Safe Mode:
I have also gone through disabling as many services and drivers as possible but no luck. Seems like it must be something to do with power management?
I'm not a gamer as a 25% CPU spike every 9 seconds would be totally unacceptable.
Another on my growing list of unwelcome "features" of this machine...
Around 20 seconds after logging in after a full reboot my Wi-Fi connection is dropped (having already connected during the boot/login).
I'm using the Intel software to manage the Wi-Fi connection and it says it can't connect because the hardware switch is set to off. This is obviously untrue.
Only solution I've found is to manually flick the hardware switch to OFF and then back to ON, then it automatically connects.
Seems like a BIOS issue if it's suddenly turning the adapter off for no reason. I'm already on the latest A07. Problem does not occur when hibernating and resuming from hibernation.
I previously let Windows manage the Wi-Fi connection but it never automatically connected at all, hence the switch to the Intel utility.
I ordered the Dell Latitude E5440 14" Laptop i5-4310U 4GB 500GB SSHD Windows 8.1 Pro, but I hate to use the windows 8.1, is there anyway I can downgrade the windows to 7 Pro ???
having issues with my Dell Latitude E5440. The BIOS does not recognise it, I tested the HD with a external caddy and it works fine. I messed a lot with BIOS thinking it could be a settings but had no luck.
I am stuck with a dell E5440 here power light comes on and then laptop switches off and back on again and just repeat itself! I did not tried anything yet. It is i5 vpro and I installed 1TB HDD few months ago, it has been working no problem since yesterday.
I would like very much for the USB ports (or at least one of them) to stay on when the computer is in sleep. I travel frequently and hotel rooms have limited power and I would like to keep my mobile phone plugged into the laptop. I've seen you answer a few questions on USB limitations and settings...
I was given a Dell Latitude E5440 and a docking station for my work. I brought in a wireless mouse and keyboard that I use for input (the reason for mentioning this will become evident later). The computer and dock were NIB and are ~ 2 months old. I have a Dell external monitor plugged into the dock via a DVI cable, and use it as a secondary monitor.
One thing I noticed early on with this setup is that the interconnection between the computer and dock is 'flimsy', at best. If I move the computer/dock on my desk by sliding it around, I lose connection and the external monitor image disappears.
My current issue is related but a bit different, I think. On 3 separate occasions in the past couple of weeks, the notebook screen has gone black without warning and the system has shut down. Once I was able to get the system back on, I was able to determine that the cause was that the battery had drained to 5%, and the system had shut down.
What I find odd is that this has happened while the unit is on the dock. What is even more odd to me is that, apparently, while the notebook has lost power connection to the dock, the video connection to the external monitor remained in tact. That is, in fact, the main reason I did not notice that the battery was draining. That, and the fact that I was never shown a warning that the battery was getting low and I should find an outlet. So, only the power connection pin or pins of the dock appear to be affected. This happened last night when I left for home. I had not touched the computer all day, since I have the wireless keyboard/mouse I mentioned above, but I did shut the lid to put the system into sleep mode. However, during the night, it apparently shut off because, the next morning, when I went to turn it on, I was greeted with a black screen stating the system had shut down unexpectedly and did I want to boot into Safe Mode. Upon booting, both PowerPoint and Word prompted me to 'recovery' my files that had been opened when the power was lost.
Questions: Why I would not receive a warning from the PC that the battery was getting low, so that I could either check the power connection or have time to gracefully shut down. That is much more preferable than the system behaving the same way it would if I had simply removed the battery when it was on.
My new T440s sees my home networks yet won't connect with passwords that absolutely are correct. Running Windows 7 (64-bit) Pro, everything is updated.
Also, it won't even connect to an open network.
This is bizarre...and makes the machine nearly useless.
I reinstalled win 7 on my hp g7 laptop and now I can't connect to my router. I'm getting message to install network adapter. When I open network and sharing box and click on change adapter settings,the screen is completely blank. How do I fix this problem if I can"t connect to the internet??
if anyone can recommend a firewall application that controls both the incoming and the outgoing traffic. The built in firewall protects from incoming request, but I'd like to control the outgoing connections as well. I did a search and found 1 thread, but it's more than a year old.
Little Snitch and WaterRoof (and its simpler version NoobProof) seem to fit the bill. Any recommendation besides these?
We image all our new systems in our organizations on SCCM. I've got one that is a puzzler. I will not get an ip from the server. Instead it displays the message "PXE-E51:No DHCP or proxyDHCP offers were received." No other computer has this issue. I does not get as far as the network boot so it is not a windows deployment service issue. And it senses if the cable is disconnected, and gives you a different PXE error. I have flashed the BIOS, no sucess. I RMA'd the motherboard, and no difference. Dell won't replace the whole system since it was a replacement for another DOA. I thought it might be that little daughter card that contains the NIC connection, but cannot see that listed on the dispatch site as a seperate part.
I have a Dell D630 Latitude laptop that connects to most Wifi Networks, but NOT my home network.In fact, It doesn't even show the network when I pull up area networks. It doesn't show any networks at all. However, when I take it to a Starbucks or McDonalds, I can not only find a network, but I can get on the Internet just fine !Do I have something blocking the network from being seen? Is my virus program Microsoft Essentials blocking the network for some reason?
I m trying to install ESXi 5.0 as a VM in LATITUDE E6430 ,but it gives me the following error
No network adapters were detected.Either no network adapters are physically connected to the system or a suitable driver could not be located.A third party driver may be required.
I have found that DELL customized image is available but only for servers (tried that too but not working)...
We have several Latitude E7240's on our network. They are configured with Windows 7 x64. We have been having trouble with this particular model in regards to wireless connections.
When the laptop is powered on and the user logs in, the laptop connects to the wireless network, however it is not getting an IP address from the router. It sticks at "limited connectivity", and gives itself a "169" IP. It stays that way for about 5 or so minutes then finally connects.
The WLAN drivers are already to the latest version, and to "bandaid" the issue, I have to uninstall the Wireless NIC drivers then reinstall them.
At first I was thinking it may be a router issue (Which is a Sonicwall TZ210W), but it can't be because its wireless devices of differing models have no problem connecting and getting an IP address. Also, it starts working once the drivers are reinstalled (though I'm not confident this is a permanent fix).
All the E7240's have the Dell 1506 Wireless card, and are all and originally were) on driver version 10.0.0.268, A02. Also, I have tried turned off any power management settings of the WNIC prior to the driver reinstall.
Cannot get online. I went into the device manager and found thefollowing:

I bought Dell Inspiron N5110 about year ago. It has beed working perfectly fine for about 9-10 months.
When i bought it i played games like CoD Modern warfare 2 and 3, Battlefield Bad Company 2 without a single lag or spike, but now, its impossible to play games like Battlefield, even games that requires less then Battlefield have lags. I play DotA2 a lot, and sometimes its impossible to play, its like having slide show. Also started to play Torchlight 2 and also its slideshow at the moments.
Acer Extensa 4420 Windows Vista Home Edition AMD Athlon 64 x2 Dual-Core Processor TK-57 1.90 GHz Radeon Xpress 1250 2 GB ram (Let me know if any additional information is needed, but those are the essentials)
The problem is that, my computer gets spikes of choppiness, it happens very infrequently when im simply IMing or browsing the web, it happens occasionally when playing low end games like MapleStory or Starcraft or Diablo2, it happens very often when playing TeamFortress2, and it makes Unreal Tournament 3 unplayable it happens so often.
I have an Acer Aspire 5100 AMD 62x dualcore tk-53 i think its at like 1.7ghz, it came with Vista, I put XP back on it, came with 1gb of ram I upgraded to 4gb hoping it would run fine. To get to the point. When I first got the computer it ran great, however now sometime with it has brought it to this annoying spike in my CPU. I've tried everything I could to keep it down, but it spikes over 100% randomly and at the worst times. I've ran Process Explorer and watched when it spiked, nothing unusual. I've watched my task manager, nothing unusual. I've defraged, ran virus scans, disabled my virus protection, uninstalled it, reinstalled it, reformated, restarted, any and everything I could. I bought a stand for the laptop and a fan so it doesnt overheat. I've check my power settings, my page file remains the same around 555 on average even during the spikes.
My laptop freezes for a couple of seconds randomly from time to time. The problem sounds like this one: [URL] .....But CC cleaner did not solve the issue.
The problem happens with almost every program such as microsoft word e.g. if I type and it freezes, the words will come out after it unfreeze.
Before the freeze, the laptop usually becomes very quiet then a few seconds later something spins and freezes the computer. I can assume that it is the HDD. However, the computer does not freeze every time the hard disk spins loudly.
When the disk spins loudly, the HDD activity spikes in task manager and the 'system' is the program that corresponds to the spike which is 'ntoskrnl'. However, the data transfer is no more that 0.1 MB/s during the spike.
I tried running in safe mode and I'm not very sure if it worked. The disk spins loudly much less often but the freeze did not seem to happen. Safe mode either tells me that it is a program/connecting to the internet/(maybe the system) that makes this freeze.
I tried a hard disk scan using lenovo solution centre and it found no problems. Also tried antivirus scan using windows defender and found nothing after a full scan.
Finally specifications: OS: Windows 8 HDD: 1TB (upgraded from 750GB) RAM: 8GB (upgraded from 4GB) intel Core i5 3210M @2.5GHz 2.5GHz Bios: v2.52
For 2 weeks or more now, my network is giving me lagspikes/disconnect when playing online games like League of Legends every time there is a bit more action on the map(ping goes to 900+).
Have windows 8.1..I am using Wi-Fi, here's a screenshot of my drivers.I dont have this problem in another city, where I'm studying(I insert cable there for connection(campus network)).Also here at home, my brother has the exact same computer and w8.1 and he doesnt have any connection issues.
I dont have torrents, antivirus updates or any of that going on while playing.We have maybe 4 computers and probably 1-2 phones using the net aswell, but that doesn't seem to be the case, as I said these problems should have occurred with my brother's computer aswell? Also when these devices are not in the house, I still suffer from lagspikes.
I don't know what it is with this laptop and messengers. But NOTHING wants to work. Heres a list of problems
1) AIM wont open (fixed, I had to change port number) So now AIM works on iChat and Adium
2) MSN wont open on the actual application (Mac Messenger) I want to webcam chat with people, and it just WONT start. It starts on adium since I checked the box to use http or something, but I can't webchat on adium.
When I try to open messenger, it says I am not connected to internet, which I clearly am...
I checked my routers firewall. And I am not too sure how to change things on the macs firewall. I just want to use messengers..
I own a Dell Inspiron 3521, and I'd been having an issue with apps not opening and closing when I do try. I went to fix this error. That's when I made a grave mistake. Somewhere along the line of me trying to fix it, I messed with something I shouldn't have and when I finished with my task, I was told to restart the computer to activate the settings. After I turned it back on it seemed normal up to the point after I saw the dell logo. It went black. At first I made the assumption that since I changed settings that it was still trying to configure them. But soon after, I saw my mouse and a little signal flash in the bottom left of my screen. So I checked around and found out that I needed to reinstall windows with disc or USB. But I don't have access to either of those.
About 3 days ago my pages app disappeared from my iwork 08 folder. The next day my safari and msn messenger were gone then today my sons World of Warcraft is missing and a few documents have vanished also.
I inspired my girlfriend to buy an Apple Macbook Pro, but I have a few questions for you. We are speaking about the new releases, which are now at the apple.com website. I read a lot about Mac and Win support, ways and so on, but you are users, and maybe someone is tried a lot...so :
The important questions are: Is there real Windows XP/Vista/7 support for the new Macs 13.3" or 15.4", for example: Is it possible to run Win 7 through BootCamp without problems, and is everything working good - Wifi, Lan, sound, touchpad, bluetooth, camera, etc.
Also what about the Applications: I'm interested in (windows versions) Photoshop, MS Office, MS Visual Studio(or some other packages for programming in C/C++ also on PHP and etc.)
What about playing movies in HiDef but in Windows, also Games?
Are there good video/audio drivers, codec packs, everything?
Explain as much as you can. Also she's going to use OS X, but I'm not familiar with the programming software in OS X. She's going to do Web design, Photoshop editing, Video Editing, Programming, PHP, C++, other also.
I just got a vaio ns with a pentium dual core t3200 @ 2ghz. I just did a fresh install of windows 7 so theres no SONY apps in there. I'm having trouble with notebook hardware control. It doesn't detect the voltage, it's basically showing ... and so I can't undervolt it and I really want to. Also when I installed NHC, it seems to take over the original settings somehow and always dims the screen to 0% when I start up the PC.
I'd also like to know if vaio's have a way to enter the bios during boot?
What are some recommended apps/drivers for me to download for this laptop? It comes with a gma4500mhd. Do I have to download drivers or does it pretty much come or auto download with the windows 7 updates?
just bought my first mac a couple of weeks ago, bought the macbook unibody. I was just wondering if you knew of any good apps that would help me tweak my appearance.
