I'm not Yelling, I need a fix. Dell Maintenance can't seem to accomplish.  I'm merely showing the amount of effort expended so far and what as been tried generally.

Offer a specific suggestion to fix.  Why can't the maintenance folks figure this out?  Notice the time they've spent.

The support is Pro Gold.

IRQ for Touchpad 12

IRQ for Gigabit Card -3  ????

The device says "no conflicts"  This happens whether the card is enabled or not.  

Nice suggestion, what next?

This is a user Forum.  Not a Yell at Dell Forum.

Sounds to me like an IRQ conflict with the Network card using IRQ 12 at the same time as the trackpad.

I'm very familiar with ProSupport policy, and although I understand you're upset with the department, understand they are spending their time trying to help you as well. They're not trying to drag out the problem, but assist you. Please contact your original case owner instead of calling back and getting someone new each time if you'd like to resolve the issue faster.

My Solution is a little more drastic, but suitable for what seems to be a drastic problem (Some steps you have probably done already):

1.) Update the BIOS to current revision, then reset BIOS to default.

2.) Clone your system using Norton Ghost or Clonezilla as well as backup data.

    -This is backup in case the following steps do not work.

3.) Reinstall Windows 7 using OS CD, making sure to format.

4.) Download (Do not use Driver CD) Drivers and install in correct Driver Order with the link below:

TRACKPAD WORKING -> Congratulations! There was some software conflicts in your last installation. Retrieve your data from one of the backups.

TRACKPAD NOT WORKING -> Unfortunately, it seems you have a hardware issue. Considering the points of failure for a trackpad would be either the palmrest and the motherboard, and your NIC's point of failure would be the motherboard or the Ethernet cable, I would recommend you replace the Motherboard and the Ethernet cable.

At this point, I see this as a very likely solution to your issue. No need to waste your time getting a new System which can take weeks when all you have to do is isolate the issue further. If you need any assistance, let me know.

Let me provide some additional details about the issue as I'm experiencing the same issue.

1: With all drivers updated or previous versions problem exists in Windows.

2: Problem does not occur in BIOS

3: Problem does not occur when driver is removed however the touchpad doesn't respond properly with driver removed and is hypersensitive and jumps around the screen when touched.

4: Problem appears to only occur in certain environmental situations however there is no rhyme or reason in which it happens. I've been able to reproduce it in multiple locations under different environments that would classify as a "normal operating environments" where other laptops and equipment operate with no problem. We are not looking at a situation where there is a strong magnetic or electrical field present. 

5: Touchpad is an ALPS Multitouch

6: I had a new system exchange performed and experienced the issue with both the new and old systems.

With all these issues Dell Engineering has captured one of the systems for further testing. I will update you when I have further details.

Dell accepted that it was a bad load of drivers, returned money.  You are definitely retarded, speedstep. You seem to only come out and try to bully just every now an then.

Nice to know Dell came through for you... People are usually quick to post when they are unhappry, but quickly post every little detail when unhappy...

At least you let the readers know Dell did the right thing.

I have the same problem on my Latitude 6420.

The only way I can make it stop is to uninstall all ALPS drivers.  Then I had to delete all ALPS drivers from my hard drive (so that they don't get auto-reinstalled).  Then restart the machine so that the default Microsoft pointer device driver is installed (dated 6/21/2006 version 6.1.7600.16385).

This minimizes any "interference" between the Ethernet and touchpad, but doesn't allow for any advanced touchpad features.

More precisely, in my case the touchpad does not stop responding completely, but it starts to respond weirdly (hyper-sensitively?) so that the touchpad becomes virtually unusable. In the "bad mode", dragging the finger on the touchpad does not make the pointer go where you want as the pointer seems to "bounce back"; even holding the hand above the touchpad may make the pointer move around or even worse, may cause mouse clicks. Over the three years I have owned this laptop, there have also been some of episodes of similar "bad mode" without LAN cable plugged in, but these have yet been very rare, so I'm currently not bothered about them. On the other hand, the behavior with the LAN cable coming from my cable modem is completely deterministic (sometimes it's not bad immediately after the LAN cable has been plugged in, but it eventually always gets bad), and this is really inconvenient.
