Hi,

I found my old Lenovo Ideapad 330-14IKB cannot be turn on, so i try repair it my self, maybe if someone had similar experience and can solve it.
This laptop when we press on button, it will try to boot but just about 3 second and display blink, suddenly goes off and again turn on and after about 3 second goes off again, but some times after 3-4 on and off , it will start to boot and working normally, but if i shut down, it happen again, on off on off.
Maybe if somebody has schematic diagram of Lenovo Ideapad 330-14IKB, please share it.

Thanks
...
