Hi there,
recently, I've got an IdeaPad with a locked BIOS, is there any way to remove it from the following dump?
That would be great!
Thanks in advance,

Model: Lenovo Yoga Slim 7 15ILL9
Machine Type Model: 83HM
Motherboard ID: LNVNB161216
TLDR: I would like to have the clean BIOS dump file for my laptop model.
Issue: First, my speaker wasn't working/showing up, so I downloaded the recommended BIOS update (from Jan 4, 2026) on Lenovo Support for my laptop. This didn't fix the speaker issue after restarting, so then I shut it down and pressed the power button for 60 seconds to perform a reset. I'm guessing I somehow messed up the BIOS because now the laptop won't turn on even after trying the NOVO button on... -
hello, I have a Lenovo that does not turn on at all, I flashed the bios but no result, the battery charges well I have 3v and 5v, the sio chip is well powered, taking all the voltages I noticed that the bios was not powered even after pressing the keyboard power button.
I'm missing +1.8VS, but I have +3VALW_APU and +1.8VALW.
Can you explain to me how to analyze the attached diagram to get +1.8VS please, thanks

Hi everyone,
I’m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.
The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.
I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip – and the last 2MB in those files are just FF FF FF....
✅ What I need:- A working 2MB BIOS dump
- Matching NM-E471 Rev. 2.0, e.g. JY575
