How do you know it's really at 400Mhz, is the reporting tool accurate? How's the heat sink & fans & airflow & temperature? Is the cpu overheating & slowing down? Battery good, does it happen only when plugged in or unplugged? – Xen2050 – 2019-04-13T08:30:28.160

@Xen2050 im checking from task manager and cpu-z the fan speed is normal ,temp between 49-50 celcius but not higher than that , i got this problem when plugged , never unplugged because im never leave house right now – Cahya Darma Wijaya – 2019-04-13T08:39:13.877

It seems to be thermal throttling. CPU select lower clock speeds when dangerous temperatures are reached. Is it an old notebook? In most cases just opening the case and cleaning the dust helps.
