Chosen Solution
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?
Lenovo legion Y540-17IHR with i7 9750 rtx 2060 2x8GB ram nVME disk Update (06/28/2020) Well problem is probably solved, partially. I took out recovery modem and for now it runs. No booting problem for now
Hi @rast1r The blinking power light indicates a low battery or at least a problem with the battery and therefore possibly the charging circuit. But since it didn’t start on the charger either and as you have done a BIOS reset, eliminating the possibility that it was a corrupted BIOS, it may be a motherboard problem. How old is the laptop? From the reviews it appears to be a recently released model. If it is <12 months old get it repaired under warranty.
