Why do you think it's a ME Firmware problem, did it happen while updating the bios, or you just receive the machine in this non working state?

Re: Need Lenovo E590 NM-B911 bios dump

Hi. I have a Thinkpad E590 and tried to make a Hackintosh and after clearing NVRAM, the laptop does not boot. Three lights come on, first NumPad and CapsLock and then after 30 seconds or so, the ESC light.

Type is: 20NB-005RUS
Serial is: PF-1REJLR
Motherboard: NM-B911 Rev 1.0

I tried to flash about 5 roms on the posts here but I believe the roms are not specific to my Laptop Type.

Please help in fixing my attached Rom or suggesting a rom i can flash using CH341a programmer.

I just tried to flash this, same symptoms. The power light, caps lock and num lock lights are on. Then after 30 seconds, the esc light comes on.

If it helps, I believe the process for hackintosh had me use Gensmbios to modify config.plist. I have the link to the youtube video i was following. At 6:20 is where Gensmbios was used.

Again, the issues started when I cleared the NVRAM at 12:06, after that the laptop restarted with black screen and stayed that way with the symptoms described above.

Didn't work. Just the power light on. I am trying to find out how to extract the bios file from lenovo update utility. It sucks that these companies don't just post the bios file, or even factory bios file. They want you to purchase their support so their employees can do the same thing I am doing, and difference is they have the correct files.

Let me know if you have any other ideas. Its either trying to get a working bios or replacing the bios chip, which i'm not looking forward to because of soldering.

try this. happened to me with a L390 and replacing EfiSystem volume did the trick.
To extract bios from update use innoExtractor.

volinakis, THANK YOU! This worked like a charm. WOW you are genius. I was so happy that I donated as well.

As a result of my E590, I had purchased another laptop L590 with a Winbond 25Q80DV bios chip. The serial is PF-1YGGLK. Machine: 20Q700ALUK. Bios installed was ROZET53W (1.31)

Some additional info on this bios is that NeoProgrammer shows as 8 Mbits and all bios files i am finding are 32mb. I get the message that bios size is greater than IC.

Hope this info helps.
