Yoga 920-13IKB No Power/Lights DO Turn On/Fans DON'T Turn On

2020-09-05, 12:49 PM

I have an issue, where I'm getting no power. 

 

Symptoms:

 

Power Light turns on momentarily when pressed

When plugged in, charging lights turns on (WHITE)

It also seems to be in sleep mode, every few seconds, whether plugged in or not, it "tries" to reset itself. The power button light and backlit keyboard turn on for a few seconds, then shut off, then repeats after about 5 seconds. And it continues to do this. 

 

What I've Done:

 

I held power button for 10+ seconds. 

I held power button for 1+ minutes.

I tried to reset through NOVO button.

I disassembled it, disconnected the battery for a few minutes. 

While battery was disconnected, I plugged in AC adapter, and same symptoms happen (power button light and keyboard lights turn on and off and repeat)

CPU fans DO NOT spin. 

I also noticed that when the battery was plugged in and i had it charging, the CPU was warming up, but fans would not turn on.

 

I am just trying to get any suggestions on what to do next, before deeming the motherboard as dead. 


Also another note to add, RAM is integrated, so reseating RAM is not an option.

 

Thank you for your time.
