My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this is the correct chip and location?
- WINBOND 25Q64FWSIQ 1715 was under the cpu fan, and is the only one that could be read by ch431a programmer. (File is attached.)
- WINBOND 25Q80DVSIG 1719 is right next to the CMOS battery, and cannot be read by the ch431a programmer. (Tried NeoProgrammer 2.2.0.10, ASProgrammer 2.0.4, and ASProgrammer 2.1.0. Tried many many times.
- I only found one post about this model and it scared me off by talking about serial numbers and Windows keys being tied too the bios. So, I don't think I should try someone else's bios.

- The file that I get from the USB Download (m11jt56usa.zip attached below) is a ROM file (IMAGEM11.ROM). Programmers need BIN files. Am I mistaken that I could just rename the ROM to BIN and flash it? The programmers can read and write the BIN.
