I am very pleased with your feedback and hear that my guide has brought life to yet another nearly dead Lenovo Laptop.
My post has been written for a long time ago. Nice that it can still be used.
Many friendly greetings from

First of all thanks for such a detailed post. I have been facing exact same issue since very long time. It has gotten worse every passing day. I read your post 3 days ago and ever since i am trying to start my laptop but it doesn't work. Is there anyway to flash bios without normal boot procedure? Fn + B will it work if normal bios doesn't boot up ?
Also i had read somewhere that by shorting cmos/ bios ic you can get it working for once. Had you tried that or do you have any idea how can i try that

First of all I'm sorry for my bad English . (google translate) I also face the same problem in the same type of laptop. I bought my lenovo z580 in 2014 with windows 8 and 2 years ago I made the free upgrade of the windows 10. About a month ago started not open the screen when I pressed the power button. in the begining is open in 5 attempts after 10. And now 30-40 times and if it's absolutely cold for 7-8 times. I wonder if the solution you give in the problem above can work in the windows 10 the bios i have is 5fcn91ww
I tried to upgrade the bios from the lenovo site but I failed.
i make a bootable usb with another computer with windows 10 and it's done but i can not get into the lenovo bios mode to activate the boot from usb because when (through the windows because novo button dont work ) I go to choose to see the bios menu I have a black screen and I have to do a restart 30-40 times or let it cool for 2-3 hours so the effort is gone. Any solution please ?
