Re: Operating System Throttling Does Not Work

Well, all I can say, is that something has chanced with XPe SP2.

With SP1 the throttling of the CPU has worked.

After I had installed SP2 the CPU has been running constantly with maximum
speed.

Actually the behaviour should be vice versa according to the KB from MS.



Is it possible, that I have to update some drivers for the main board??

Are there any ideas else?
