Y540-17 wont turn on, power and keyboard blinking.
Well I have lenovo legion Y540-17 laptop. And suddenly I stumbled a problem. One day after restard the laptop didn’t came back. The power and keyboard light started blinking, only holding power turned off the whole thing, and couldnt power it up. Took out the battery, and CMOS held power for 30 sec to powerdown all. Then put back CMOS and battery, it was blinking all over again, but pressing novo button turned on the laptop. And it worked, unfortunetly not for long, last night I turned off laptop with some updates, it looked all fine. But after sometime it looked like the laptop wanted to turn on, and it got all over blinking loop. So I tried taking out CMOS with battery, but this time this doesnt work. After turning on, for a while power buttom blinks fast for about 15 seconds, then the vents try to run, the light on power button keps blinking but didnt make it to run. Does anyone have an idea what should I try next?

Questa è una buona domanda?

Hi @rast1r ,
As you didn't say whether or not you had the charger connected, what indications do you get when just the charger is connected, is it charging OK?
If so allow it to charge for a while and then try turning it on with the charger still connected and check.

Well I tried, if the chager is in the light near the connector is on all time(doesnt blink like the power and keyboard). I even tried without battery and just connecting charger.

I have the same problem but don’t have a battery in mine. Could this be my charging cable?

Hi @j.d.topp
Could be. Any lights? If not try moving the cable around to see if that helps.

Hey,
The problems is actually regarding the motherboard.
In my case it was with the keyboard bus connector(cable) on motherboard.
I disconnected that cable and turned own with nova button, which is a temporary solution. Later replaced my motherboard, luckily i was in warranty period.
In your case it can be due to other cable too.
Try checking your ram also.
Thanks.....
