Vista Sleep and unexplained C.P.U. activity.

  mooly 11:13 14 Feb 2008

Hi, I wonder if anyone can explain what is going on when I use sleep. I have ACER ASPIRE 9301 Notebook running Vista Home Premium. Normally the C.P.U. will idle at around 3%, however if I use sleep, on waking the laptop, the C.P.U. activity dramatically increases and never returns to a low value until a full shutdown and restart. What is strange is that the C.P.U. resource info in "Performance Monitor" shows the graph of C.P.U. as continually hunting between say 5 and 40 % with an average of around 30% over a couple of seconds. The drop down list of processes using C.P.U. shows MMC.EXE (Microsoft management console) as the highest at only 1.5%. There is also zero hard disk activity. The processor must be doing something as the fan comes on and stays on in this state, normally would only come on very intermitantly. Anyone any ideas ?
