Multiple occasional problems - no Ethernet, no mobile broadband, Internet Explorer/Connectivity freezes etc - and few workarounds

Problems with the laptop Dell e6400 and possible workarounds

-          Problem 1

  • Not possible to switch internet options (specifically Connections) in Internet Explorer’s settings (the menu hangs).  Usually, this happens when I boot the laptop on battery. Characteristically, the Dell ControlPoint Connection Manager tab shows during the boot up and it is impossible to make it disappear (i.e. not possible to close it).  Also, it is then impossible to shut the notebook down properly. I have to kill the non-responding programs (Windows shows which ones do not close during the shutdown and offers to kill them), as they do not close regardless how much time I give (once I tried some 6 hours).

-          Problem 2

  • Sometimes (I believe this is also attributed to working on batteries), the mobile broadband (GPRS/EDGE/HSPA) adapter becomes disabled due to the need to “activate” it and impossible to use. The workaround is to reboot the laptop again – annoying.

-          Problem 3

  • Sometimes, when I switch the brightness of the display whilst the notebook is logging in/booting up (I believe, this happens after logging into Windows), the system starts to misbehave (e.g. display problem 2).

-          Problem 4

  • When I connect the computer to the docking station, the Ethernet stops working. The workaround is to disable and enable the Ethernet adapter in Windows Device Manager. Well... yesterday it did not help and I had to reboot computer and then enable the device. The Ethernet was then recognized and started working. Unfortunately, the CPU was then loaded 100% (by System Idle process) and killing the programs sporadically showing upto 53% CPU load, did not resolve the issue. I think this must be a driver issue (which driver I do not know).  Just now, I again did not have the Ethernet and, miraculously, the Ethernet got connected (after some 2 hours of working).

-          Problem 5

  • The fun is often working excessively, despite seemingly low CPU load (~5-10%; no computations or graphics, e.g. just using MS Word), making annoying noise.

-          Problem 6

  • I have tried to install Dell Mobile Broadband manager, but it is unable to work, saying that ‘The mobile broadband device is not communicating’.

-          Problem 7

  • Sometimes Dell ControlPoint Connection Manager drops the connection established with Intel ProSET/Wireles WiFi Connection Utility. This may happen after I worked for several hours using the WiFi connection established by Intel’s utility.

-          Problem 8

  • Frequently, having Bluetooth enabled drops the WiFi connection (at 2.4 GHz). Interestingly enough, some long time ago (in 2009?), they were able to work simultaneously with no such problems.

-          Commonality

  • Many of these problems seem to be attributed to switching from the mains to the batteries and back. The main workaround is to boot up on mains, THEN switch to batteries, and, probably more importantly, connect to mains BEFORE shutting down.
  • The reinstallation of Dell software solves the many of the problems (I have not tried if it solves all of the problems) ... until the first disconnection from the mains and going to battery.

AlbertL,

 

Recently install Windows? Did you install the drivers in the correct order? How to Download and Install Drivers in the Correct Order

 

I have heard that some people cannot get Dell Control point to work properly.

In the beginning, everything was done, as per the guidelines from Dell. However, as the time passes by, new updates come up. How does one handle it?

one more question - why do the most of the programs from most of other reputable software providers "just work", regardless of the updates to the system? with Dell software, updating things is always a challenge... 😞

AlbertL,

 

On the initial installation, especially if it was a fresh installation, the desktop/notebook system(if applicable) and the chipset drivers need installed first. These two drivers know what is attached to this system and allow the connection of these devices so the drivers can then be installed.

 

Once the drivers are installed, the drivers, in most cases can be updated with no problems. I usually do not update drivers, unless I have a problem with a device and then I ask before trying things. I also create a system restore point so I can go back to what worked. Dell's process for drivers, when they're released, it takes some time to test them, so that's why Dell's website looks like the drivers are not current.

 

I have tried a third party FREE application to update the drivers and it updated most of them. I would suggest if using Windows Updates for Windows ONLY. If Windows Update offers new drivers, do a little research first.
