lenovo s920 random reboots

[Guest d2sarwono]

Hi,

I have lenovo S920 that randomly reboot itself recently. I have tried to factory reset and even flashing stock rom but the reboots still wont dissapear...

However yesterday I found out that using different governor than the default one(by set cpu) stops the reboots..

There are on demand, hotplug (default), userspace, powersave and performance governors available. The reboots is there if i choose on demand or hotplug(default) but dont appear on any other government...

Do you guys know what causing these and how can I fix it?

Thanks in advance
