I have a Latitude E6400 that I recently clean installed Windows 7 ultimate on. Everything was working great and continues to work great undocked. When in the docking station (), however I tend do have problems. I thought initially it was just related to the NIC card as it seemed to only start misbehaving under a lot of network activity and disabling the NIC and running only on wireless seemed to fix it, but in ALL cases I have to do a cold boot. Simply restarting it would not help and when I finally would get logged back in after a simple restart, the CPU was already pegged. Today, however it seems that even with the NIC disabled that it also exhibits the behavior although today I was using an external USB drive connected to the docking station. i have since removed that as well to see if I can stabilize. I've downloaded and installed every latest
driver/bios/firmware I could find. Nothing has worked...
What occurs is over time, and sometimes that's not long, my CPU quickly pegs at 100% and stays. There are no particular processes pegging it either. I can end process on many in my list with no change. Over the last week I've only been in the office a couple of days using the docking station and on each occasion I have problems at least 2 - 3 times within the day. The rest of the week I've been undocked and had no problems and I run this thing all day long.
I have no messages in any logs that I've found indicating any type of problem. Just extreme frustration.
I've talked to a couple of other D-Series users who suggested that they had a similar issue when docked but found some vista 'docking'
drivers that fixed their issue although I can find nothing for the E-Series, no firmware, nothing...
Any ideas? I'm about to have to roll back to XP and not excited about the thought as I need the docking station for multiple monitors, etc...
Tks,
