The CPU load is very high all the time. Even fresh after starting matlab with no variables and no programs running.
Its about 35%-45% all the time. Here you can see the trace in time of Matlabs cpu load:

Setup: r2012a on win7 64bit, 8gb ram, 200gb free disk space,intel U9400 2core cpu(laptop),java Version 6 Update 31.
What can be causing this?
