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.

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

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Hi all! I was reading on tutorials how to flash a bios to remove password from a bios, and I ended up reading the EC chip instead of the main bios chip, it only gave me a .bin file of 1,024kb, I learned later that that is the EC chip not the main bios chip (I should have read the tutorials here instead before attempting anything, my bad), I went to flash the original backup, the 1,024kb size file into the same chip and laptop is not powering up anymore. I may have screwed the chip or even the motherboard (Hopefully not), I am trying to see if there is a fix before I discard it. I had a couple...
