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... -
Hello everyone,

So far I've been a silent reader, but now I need your help
I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele... -
Hi!
Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).
Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...04-14-2025, 01:56 PM -
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 everyone,
Iām 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 ā and the last 2MB in those files are just FF FF FF....
ā What I need:- A working 2MB BIOS dump
- Matching NM-E471 Rev. 2.0, e.g. JY575
