Hallo friend, I have problem with Lenovo E590. After repair USB-C connector notebook can´t boot. After press power on button only beep some sound and I analyse it witch LenovoPCDiagnostik App as error 0284 (TCG-compliant functionality-related error). I search it and I read on some website, that maybe flash bios can help. Can you get me a bios dump for this motherboard please, or do you have some another idea?
Thank you so much for your reply!

Thank you for reply. I try your BIOS and no working. Only blinking power LED slowly after power on (without melody). The fan doesn't even spin for a moment. For test I try flash my original BIOS and after power on play melody again. LCD is black. Only play melody, power LED lights up and CPU FAN spin for a moment. Do you think the motherboard can be defective?Comment

Apologies for asking for help
NM-B911 board, PLT_RST# present but no activity other than a backlight activation and 5V on USB/HDMI.
Tried a few other sample BIOS bin's here but none did anything ( in fact even worse ).
Original BIN attached here.

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 all,
I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful.... -
Hi all,
This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.
I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

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
