An hour and two minutes after i power on notebook process "System" starts constantly using the CPU at around 14%.
I discoverd that ACPI.sys!RestartCtxtPassive is the process that is causing the CPU usage and the only way to stop it is to put the notebook to sleep or to restart it. After another hour and two minutes process starts again.
I tried diferent operating systems, Win 7, 8.1, 10, and every driver combination that i could find but without any luck.
I installed only Windows without any drivers or additional software but the problem is still there.
Can anyone help me out?
I didn't find the right solution from the Internet.
