Regarding to run32dll.exe and 100% CPU resource,
I did a google search, some T41p owners suggested
it might be caused by BluetoothAuthenticationAgent and BatteryMaxiMiser.
I try to disable BatteryMaxiMiser from displaying on task bar,
the run32dll.exe process is gone. Also there are couple missing files from BluetoothAuthenticationAgent,
BatteryMaxiMiser, and ATI driver for 3D Studio Max.
Disable them with Windows Startup Inspector seemed to fix the problem for now.
I hope IBM can release update software utility to fix these issues.
