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

Hello form Poland.
My name is Peter and I live in Poland.
I've been repairing electronics as a hobby since I was born (I never make money from it).
I want to finally fix the bios in my old Dell E6540, so I decided to sign up here.
Of course, if I can help you, I'll be happy to answer.
Best regardsComment

I have a maker world account @stevens.colt. if you need help with a design hit me up, I am busy but can help where I can.
Nice being here and look forward to learning more.
