Black screen. No BIOS read-outs. Not possible to enter the BIOS menu. CPU fan, hard drive and other indicator lights up and works normally.
PC starts normally at about every 30 attempts. In this case, the BIOS (F2) or Windows 7 starts normally. Observations suggest that PC will only start when it is completely cold, ie when it has been off for at least 2 hours between 2 start-up attempts. This time can be reduced to about 15 min, if cooling elements are placed on both sides of the motherboard (below the PC, and on top of the keyboard).
What has been studied / tried?
Power supply and connectors - ok.
Battery ok (though worn and should be replaced because it will no longer charge for max capacity).
CMOS battery holds 3V (although volt drops at loads > 5 mA).
Ram, HDD and CPU is tested / changed and found ok.
Motherboards (incl. Graphics chip) has been tested and found ok using various test programs from the official Lenovo Support.
Visual inspection of the motherboard: Nothing to report.
Heating the graphics chip using heat gun (in order to eliminate any cold solder joints) did not solve the problem.
Attempt installation of the latest original BIOS executable file from the Lenovo Support (only possible under Windows) fails:
Attempts unpacking of the original BIOS executable file from Lenovo Support succeed not in spite of several attempts.
Attempting to install the 'BIOS alternative made' (Links.C) using. Phoenix BIOS Recovery (WINCRIS.EXE) also fails.
On another PC, perform the following:
On the sick Lenovo PC perform the following (and it is a prerequisite that it is one of the times where the PC has "desired" to start):
Now BIOS is updated and the PC can start as normal and without any problems !
However, there are a few things that should be corrected:

I first want to say thank you for such an informative, detailed write-up.
Everything in the procedure worked for me, with no issues, until the (optional) step of "Download and install the latest original BIOS Lenovo Support." I downloaded the Z580 BIOS updater from Link A, released 8/13/2014. Upon attempting the installation of the first file, Public.exe, it appears to be successful, the computer reboots, and then is stuck gets stuck in an infinite boot loop asking to select the boot device. This has been detailed by other users, Link B.
If you decide to attempt the Lenovo BIOS update and get stuck in this boot loop, try the following:
Note, I did not have to reactivate Windows after this procedure.

I am definitely going to try this with my dad's pc when I next see him. He started having these symptoms a few days ago, as posted here: https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Z580-black-screen/m-p/2255120#M138693
Thank you for the detailed write up, really appreciate it. I just hope it works!

first, sorry for my bad English, hope you understand me.
Have the same issue with my Z580. My USB-drive is equiped in the way described.
It appeard first some weeks before christmas 2015. Because I need my laptop at the moment, I let him run, all the time. I switched it off by accident one times, one time an Windows-update, and the day before yesterday, I got a bluescreen. Now the laptop doesnt start anymore. Tried it several times. Guess about 200 times for now. But nothing happens.
Are there ways to force the laptop to start? Im sitting in front of my open window, to cool it down, and its cold outside...
Or can I update the Bios in another way? Without the laptop running?
Dont know, what to do. Dont want to buy a new laptop, if the problem can be solved that easily.

Your method fixed my issue.
The problem you described was precisly what I was having.
The laptop was laying around for a week-- unable to do anything with it unitl I stumbled across your solution. It took me about a day of idly turning the laptop off and on trying to switch the BIOS order. Then another day trying to get it to boot for the second time and finally booting through the USB.
I'm so glad you took the time and effort to write on the forum your solution. I'm eternally grateful as this laptop costed me a pretty dime and I really thought it was for trash.

I just want to mirror what spacemudd said. I finally got around to looking at my dads laptop at the weekend and it's now working, and £300 on a new laptop has been saved. Thank you very much.
Although, I almost gave up when it wouldn't boot from the USB! Turns out, there was a setting in the BIOS where you can turn USB boot on or off. Once I found that, everything was a piece of cake!

My one doesnt start anymore ...
Is there any possibility to force the laptop to start?
Or to get into the dos-mode?
Is it the colder the better for booting?
Thanks for help
