Hi, hope you are doing great.

I need to flash BIOS on a Lenovo IdeaPad 3 (Takes power, keyboard backlight lights on for a second, power button blinks all time, rest of the keyboard keys stay put, CPU gets warm)

Mfg Date: 2021/12/18

The bios you posted is empty and only has 4Mb...it should have 16 MB...make a new copy and post again..

Thats what came out from the programmer from the original BIOS, maybe thats why it was bad? I flashed it with the new BIOS anyways so it is lost. Is there a way i can configure a new BIOS from the start?

You selected wrong chip model MX25U3235F (that's what the file name says), the BIOS chip should have 25*128 on its name (16 MB)
Your first backup is full of FF FF FF .... the chip was not read properly or erased before
Try again, select the correct chip model, if you have a 74M12JW select W25Q128JW on your programmer software
Flash post 52 as is (select the correct BIOS chip model first), you don't have a good original backup to transfer the DMI from, Laptop should boot and display INVALID serial/MTM/model name so you have to use Golden Key to enter model/serial/MTM after laptop boots

I flashed BIOS from post 52 with W25Q128JW selected, but still same behavior from the laptop. I notice the power button starts flashing as soon as i press it, possible bad CPU?
