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?

post the contents of the bios chip even if it is corrupted..

post the contents of the bios chip even if it is corrupted..

Here are the device details:

• IdeaPad 3 15ALC6
• MTM: 82KU00WEIX
• S/N: PF3RKDL2
• Motherboard: HS461 & HS561 & HS761 NM-D521 Rev 3.0

I apologize, this is what happened. I’d like to understand how to proceed.

There was a Windows update that also updated the BIOS to version GLCN68WW, and from that moment the laptop no longer boots.

I need to flash the BIOS on a Lenovo IdeaPad 3 (it powers on, the keyboard backlight briefly turns on, the power button keeps blinking, the rest of the keys remain lit, and the CPU gets warm).

I’ve read the guides but honestly I understood very little—I’m not an expert.

I managed to trigger crisis mode and I tried flashing a few .bin files, but the USB drive only blinks for a moment and then stops. The fans spin up, but nothing else happens. I think I’m doing something wrong.

I tried downloading version GLCN52WW, extracted it, renamed the BIOS.cap file to BIOS.bin and placed it on the USB drive — still nothing.

Then I tried removing the header (resulting in an 8192KB file), saved it as BIOS.bin, but again nothing.

I also tried some .bin files posted by other users in threads about the same 82KU model, but no luck.

What else could I try?

You need a hardware programmer to read the existing contents of the BIOS chip
BIOS chip is 1.8V, make sure programmer supports 1.8V chips otherwise you will damage it

I don’t have a SPI programmer, and honestly I wouldn’t even know how to hook it up or read the current BIOS contents.
Is there really no way to overwrite the BIOS without reprogramming the EEPROM directly?
Can’t it be done using Lenovo’s crisis mode?

Re: Hs461 hs561 hs761 nm-d521 rev 2.0 bios plz



Here's your New bios file, it's a virgin bios from Lenovo with your DMI so it should works fine.
Next time find your device thread or create your own.

Thanks !!
