It's my laptop. It was powered off properly and did not start again. All sources on the motherboard are fine, but the computer does not start. The power LED is on all the time. I can power off and on again de motherboard from power button. I suppose it's a bios fault. I tried the bios posted here and none of them work.
I am attaching my backup.
Thank you in advance.

Here's your new bios file, try it and let me know the results.

Re: Hi pls lenovo z50-70

Thank you for such a quick reply.
I tried the BIOS modified by you this evening and it doesn't work. However, there are other symptoms: after about 30s, the fan starts and works at maximum speed.
I also tried to extract the flash from the BIOS file on the official website (it's different from the one modified by you) and it still doesn't work. More precisely, I extracted the .exe file with 7zip, and then, using HxD, I searched in the isflash.fd file for the beginning of my file. I selected starting from there the 800000 block and saved the file, then I wrote it in memory.
Exactly the same symptoms as with the file processed by you.
Any idea?
This is the file I obtained

Our files are the same, the only difference is the device information area because I moved it from the original file.
Perhaps you have a hardware issue.

Re: Hi pls lenovo z50-70

It could be but I don't know what else to check. I checked all the sources and they seem to be fine, I disconnected all the components from the motherboard, I tried with another RAM, the processor cannot be replaced with the tools I have. I will probably abandon it. Too bad I've only had it for a month...
Thanks for your time!

Upload your bios backup, serial number and issue description. Do you have discrete graphics onboard or only integrated Intel gpu?

Re: Hi pls lenovo z50-70

Hi, I have a Lenovo Z50-70 (with Core i7-4510U and Nvidia GT820M) that wouldn't boot. After some investigation, I reflashed the BIOS with one that I downloaded from elsewhere on this site. This got it working again, proving that BIOS corruption was the cause of the original fault. So far so good!

Of course, this temporary replacement BIOS does not contain any of the identity data from of the original and it also seems to take a while to boot, which makes me think that the ME data was not cleaned. It would be great if someone could take the identity data from the original BIOS (downloadable from the attached link) and put it into a clean Z50-70 BIOS for me. If you also need the serial number it is YB07250264

It would be even better if they could share how they did it so that next time I can be self-sufficient!
