I've a big problem with my R61 8943-DMG in combination with the advanced mini docking station. If my notebook is docked in , i have a system load of 50%. But if I undock my ThinPad , the cpu usage goes back to normal ( 1 - 2%). After checking the task manager , i saw that the process "System - NT Kernel & System" is using 50% of the two cores in idle mode. Running a virus and maleware scan , was without any negative results. I'm using Windows Vista Business and XP. The problem exists only on the Vista system. Under XP this problem does not exist. The two operating system , does nearly have the same software configuration.
Does anyone have an idea how to solve this problem ?
When docked, the TP has to look after the extra ports etc. from the dock itself. Is there any other hardware attached to that dock that requires constant action of the CPU, or is it 'only' docked without other attachments?
When docked, are there any yellow or red marks in Device Manager?
All atteched hardware is installed correctly. I'm using an external TFT , Mouse and Keyboard - but these hardware doesnt use the CPU *g*. All eventlogs are clean. No failure logged.
To be sure that i don't have a virus or someting like that , i've started a virus scan in save mode. No infection detected. But i've seen that the system process uses under save mode onyl 1-2% cpu time.
Edit : I used another notebook and by comparing the running process i saw that on the other vista system the system process is using ~ 3.000 Kilobyte of ram. My Vista System process uses only 136 byte. I think this could be the cause of my problem.
