Sometimes when the computer is connected to the power supply, the processor starts to run on a vey low frequency (around 400 mhz) for a few second, after that everything is normal, this behavior continues till i turn off and than on the computer. I don't know how to repair this issue. When this issue occurs I switch the computer to the high performance mode and this doesn't help at all. The only solution I found is to turn it off and on again and it's annoying.
