Dell Latitude E6400 :: ATG Mouse Pad Works Intermittently
Nov 28, 2012
Dell Latitude E6400 ATG mouse pad works intermittently. It will work then stop and I have to use the keyboard nub. Then it will work. Then it will not work and it will drift to one corner. If I press on either side of the mousepad wrist rest area it will drift faster.Â
This is why I think it is a hardware issue.
I have updated with the most recent driver several times and it does not correct the problem. Driver is dated 1/13/2011
My 15Z touchscreen works intermittently. It will be working just fine, then it starts to take a second to respond. Then it stops responding at all. Then it starts working again. I cannot identify any pattern to it.Â
I have been having issues with audio on my G500. One moment it works and the next it doesn't. I don't quite know what can be the issue. I have tried multiple browsers to see if that is the issue and it has not made a difference. I am running Windows 8.0, 64 bit operating system if that makes a difference. This laptop is not even a year old.
I have had my Inspiron 7347 for a few days. When operating on the battery, the touchpad exhibits some quirks that make this P:C extremely hard to use as a portable laptop.
The mouse on the touchpad hangs up intermittently, sometimes for several seconds. This erratic behavior makes using the mouse terribly difficult.
When scrolling using the mouse on a vertical scroll bar, the right click menu for the desktop keeps popping up.  I must move the mouse away from the scroll bar, left click to get rid of the right click menu, and return the mouse to the scroll bar. Sometimes this behavior is constant when scrolling through a long page, making it impossible to use the mouse to scroll.
I have a one year old sz680 CTO with a bluetooth vaio mouse VGP-BMS33. The strange thing is that the mouse only works well when I position it to the left of the vaio.
When I have it between me and the laptop, the mouse pointer moves in shocks, and on the right it doesn't work at all. (As a test, I also tried it behind the laptop and there it also in shocks).
I have tried to move the laptop to a different location, away from external power. I have turned of wlan & wwan. I have used different batteries, both common and rechargables.
I have a latitude 3540 . Recently I installed windows 8.1 64 bit on it. All the drivers works except the WiFi. When I am trying to install it its showing a message "The installer cannot run on this platform. Pls select the package for your operating system". Â I tried both older newer versions of the driver package downloaded from dell website.
My keyboard has intermittently been working for some time. When it works, then everything works as it should, when it does not work, the keyboard is still lit up and the mouse joystick still works, but no keys work. To get the keyboard to work again I have to reboot and shutdown many times and eventually it will work again. It only stops working after shutting down or rebooting. To me it appears to be an issue with detecting at boot up. It seems it could be either an issue with the motherboard, or the keyboard so was or to get some opinions on how to narrow it down to one or the other. I should also add, that when it does not work, you can not access the bios, or anything prior to the operating system loading, so I am 100% sure its not an OS issue. I also dual boot this laptop and the keyboard does not work in either. I can plug in a usb and that works fine.
The price of 2nd user Latitude D630's seems to be holding up quite well in the UK. Does this indicate that it is still a popular machine and favoured over the E6400?
I briefly checked out an E6400 the other day and for a choice between machines of approximately similar spec I would opt for the D630 rather than the newer E6400.
I would be interested in opinions from users who have experience with both models.
I'm working on a Dell E6400 that has a peculiar problem. When the laptop is off, and connected to its Dell docking station, and I try to boot, I get "NTLDR is missing" errors and it will not boot.
When I'm using the laptop to write documents... or emails my hands brush over the touch pad and the slip act of swiping the neatly organized lines of text becomes jumbled gibberish
How do I disable the touch pad when using an external mouse?
I've had this problem for quite a while. I'm unable to register Microsoft mice with the bluetooth on my Latitude D630.
I originally thought it was the mouse I purchased ... but the mouse worked fine when I used the bluetooth adapter that it shipped with.
I recently purchased a MS Presenter Mouse 8000 and tried to register it with the bluetooth stack. Every time I try I get a "Registration Failed" message.
The software can see the mouse ... and I hear the standard "Registering hardware" chimes, but then I get the "Registration failed" message.
I'm running "Bluetooth Stack for Windows by Toshiba" version 4.31.02.6(D).
Mouse is jumping all over the screen - I believe because it is easy to accidentally brush the touchpad while typing.
The Control Panel - Mouse on this Latitude no longer has an option to independently enable/disable the touchpad and the pointing stick - but surely there is a way to do this on this e4300.
Okay, I can't get the "feature" of the touchpad to work where it "disables when a USB mouse is present"
Reason:Â There is a perpetual bluetooth mouse appearing in the device manager.
I actually have 3 mouse devices listed: Touchpad, HID-Compliant (bluetooth), and HID-Compliant (Wifi). Numbers 1 and 3 are correct. Number 2 is not really there,
When I pull the WiFi dongle, the #3 mouse correctly goes away, leaving me with two.
Clearly, the touchpad is detecting a "HID-Compliant" mouse "on bluetooth". BUT THERE IS NO MOUSE PAIRED. I tried to uninstall the bluetooth software from Add/Remove (or whatever Win7 calls it this year), but the device is still there. So I did an "uninstall" of the device in the device manager, and it comes back. (yes rebooting between all attempts)
So, something, somewhere, is claiming to be a mouse on the bluetooth stack. How do I make it go away, since it's not really there? Because it is causing the touchpad software to disable, thinking there is another device.
Additionally, when I forgot my mouse, I tried to activate the touchpad... Do you realize that it is completely *impossible* to manipulate the user interface to the Tochpad applet in the control panel without a mouse in the first place??? You cannot make the "save" button activate. This is the ultimate in poor usage design.
I've got a dell Latitude D410; after it shows the Dell screen and the Windows XP screen (with the loading bar down the bottom), it goes to a screen with a blue background and a frozen mouse; after a while the mouse starts working but nothing else happens. I've tried booting from Last known good configuration but didn't work.Â
I have 7 Latitude E6320, all with identic Confgiuration and same Problem. Sometimes the Laptop freezes. When this happens I can still click one to three times somewhere, move the windows and mouse, then no Application reacts anymore. I can still move the mouse. It's not possible to start Taskmanager or kill Processe via Process-Viewer. If Process Viewer runs before the Laptop hangs it shows high load at "Hardware-Interrupts" ~30%. If this happens the HD-LED is on without any blinking. The only way to get out of this is to turn the Laptop off.
There are no Errors or Warnings in System-Log (only at restart).
All Updates from DELL (Drivers, Bios) and Microsoft are installed (including SP1 for WIN7). Diagnostic boot runs without Error. the sfc command runs also without any Problems.
What can I do ?.. I want to avoid to reinstall Windows 7 & Software (32Bit) on 7 Laptops...
Is there any known Problem with this Laptop ?( In the last days a few new BIOS has been released .)
I'm pretty new to Dell notebook world. I was always told that Dell has a stinky customer service and their image wasn't that good around spot but care sharing whats good and bad about dell in general?
1- In the LCD option, it says touchscreen. Does that mean I can somewhat use this laptop like a tablet? ( Without the ability to twist the screen of course..)
2-Never knew whtas the different between 1dimms and 2dimms in RAM....
3-Compare Geforce 9400gs with the Mobile Intel® Graphics Media Accelerator X4500HD With PC-Card. Plus, what do they mean by "PC-Card" or "EXpress card" ?
4-Does Dell notebook actually give us 64bits windows or they're all 32bits unless they mention the option of 64bits?
5-Whats the difference between the normal e6400 model and the ATG model? Simply more durability +weight?
6- Whats an encrypted HDD or a ruggedized HDD?
7- I'll be using the notebook for design purpose. Such as photoshop, flash, illustrator or such. I'll be using 2-3 program at once with several picture/projet +internet + music. If my specs are 2.26ghz or 2.4ghz + 4gb ram + intel HD4500HD, will this notebook handle it?.............................
Its a certified refurb; it has everything i want at a great price:
-- Latitude E6400 Laptop: Intel Core 2 Duo P9500 (2.53GHz, 6M L2 Cache, 1066MHz FSB)
-- 14.1 inch UltraSharp WXGA+ (1440x900) LED Display
-- Back-lit Keyboard
-- Genuine Windows Vista Business
-- Brushed Metal Black
-- 24X CD RW/DVD Combo Drive
-- 2 GB DDR2 SDRAM 800MHz (1 DIMMs)
-- 90W AC Adapter
-- 9 Cell Primary Battery
-- 125V Power Cord
-- Mobile Intel Graphics Media Accelerator 4500MHD With Express Card
-- 250 GB Free Fall Sensor Hard Drive (7200 RPM)
-- Dell Wireless 1510 802.11a/g/n Draft Mini Card
-- Integrated Webcam with digital microphone
Im upgrading the RAM to 4gb, and maybe the hard drive if its too loud. I got the integrated GPU on purpose so it runs cooler and quieter and has better battery life (I don't play games). Ill try for a new version of vista too. Im happy i got the p9500, that was probably the only one left that was a decent price,
I'll be able to order my new E6400 soon, as follows:
CPU: Intel P9700 2.8GHz GPU: nVIDIA Quadro NVS 160M / ExpressCard HDD: (whatever is cheapest) I'll replace with a Scorpio Black or Blue (see question 5) MEM: (whatever is cheapest) I'll replace with 2x2GB of Corsair DDR2-800 WI-FI: (whatever is cheapest) I'll replace with an AR9280 half miniPCIe card LCD: WXGA+ (1440x900) LED-backlit - Backlit keyboard, Bluetooth module, 6-cell battery
Keep in mind that I won't be running Windows on this machine, but instead, Linux (Arch Linux x64).
Questions:
1) Is the nVIDIA Quadro NVS 160M enough to run Compiz-Fusion smoothly?
I previously ran Compiz-Fusion with an Intel GMA X3100 integrated GPU and was underwhelmed. Everything worked, but the animations were pretty herky-jerky, most of the time. Aero animations under Windows 7 were similarly not very smooth. I'm hoping for more with the nVIDIA Quadro (I read one report that Aero with an E6400/nVIDIA wasn't very smooth).
2) How bad *really* is the touchpad?
I've heard reports that the touchpad is imprecise and laggy, but I've also heard from people who say they haven't had any issues. Is this a "hit or miss" situation with the hardware, or is it due simply to what people are used to? Or has this been fixed?
3) How durable is the lid/screen?
I've heard reports that "the E6400 is well-built and durable ... except for the display," with no real elaboration. Is there any truth to this? Bending, flexing, etc.? Screen distortions if pressure is applied to the back? Does it seem strong? Feel strong?
4) Does the "brushed-metal" on the back of lid look good in person? Or does it look cheap, fake, tacky, etc ... ?
5) Can I replace the hard-drive?
I heard from one owner that the hard-drives used in the E6400 use a non-standard SATA layout, and thus aftermarket hard-drives cannot be installed. That seemed like it would be a very stupid thing for Dell to do ... but I thought I'd ask.
6) After time (6-12 months), does the display start to wobble when open?
I had an Acer Aspire 4720Z (I know, cheap quality) whose display would wobble when open. At the top of the screen, probably about 1/2" to 3/4" of wobble. The Dell Inspiron 1521 I'm using now does the same thing ... very annoying. Does the E6400 exhibit anything like this even AFTER extended ownership? Say 6 months to a year or more?
7) Is the audio bad?
I've heard from a few people that the audio is simply horrid, even through headphones. I've also heard that disabling PC Spk has fixed it for some people ... is this an outdated issue that has been fixed by Dell?
8) Is there anything else I should know?
If there's anything else that I need to know, I'd love to hear it.
Sorry for so many questions, but this will be a big purchase.
After reading this thread: E Module Bay 2.5" drive. about the possibility of a second hdd in the Latitude E Series I wonder if it is possible to use Raid0 with E6400 as mentioned in the manual. Looking after it in the Bios I can't find any Raid Modus for SATA-Operation. Any ideas???
I have been reading about people getting so many hours out of their E6400. I have the 9 cell battery and running the screen on the lowest setting, Bluetooth off and wifi on im getting close to 6 and a half hours of battery life. Is this normal....
I heard about doing a clean install, what does this do, and what benefits would i be achieving by doing this?..
Is there anything else i can do to get a little more juice out of the battery when i need it? I plan to have wifi on most of the time when it is being used. Basic web-surfing and Microsoft word...
I am trying Windows 7 on my Latitude E6400, and I am having two a little issue for the system.
First issue is despite enabling advance performance for the drive under Device manager, Windows 7 gives me score or 2.0, than in Vista the score is significantly higher in the 5.0 range. My HDD is the Hitachi 5400RPM 160GB.
Second issue is, I don't know what I missed when installing the drivers/software, but I don't have the on-screen volume control. But the ambient light sensor, brightness level and keyboard backlit mode, does appear.
