          Need BIOS Dump/ROM for Lenovo Thinkstation p500
          by AHmad_Salal
          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....

          Lenovo Yoga X1 Gen4 - Faulty Bios or what is going on?
          by AYsys
          Hello dear forum members,

          I own two Lenovo Yoga X1 Gen 4 laptops. One of them had a touchscreen problem, and I tried to fix it by externally flashing the BIOS. Unfortunately, I didn’t save the original BIOS and accidentally flashed it with a faulty one. After that, the device stopped working completely.

          I then had the idea to make a BIOS backup from the other Yoga X1 Gen 4 (same hardware) and flash it onto the non-working device.
          Nothing was flashed here — the BIOS was only backed up.

          I created the backup using a CH341A Black programmer and NeoProgrammer....

          [REQUEST] 2MB BIOS Dump for Lenovo NM-E471 Rev 2.0 (Winbond 25Q16JWSIQ Chip)
          by hyperwood
          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
          ...
