    Lenovo Thinkstation P620 Bios Request

    I have a Lenovo Thinkstation P620 which is not turning ON. Fans are spinning but no display.
    I think it is bios error. I tried to read bios from chip winbond 74M25JWEIQ ON RT809H programmer but it was not in the winbond list. I read with defaults options but all the reading are just blank bins. Can anyone help me fixing the my PC
    Model: Lenovo Thinkstation P620 30E1S66110
    Serial: PC2AK0M7

      post the contents of the bios chip even if it is corrupted..

      The bios chip must be unsoldered from the board before writing or reading..
      do not use the clip, you may have errors..if you do not have anything to unsolder it with,
      solder wires between the programmer and the bios chip..

      you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

      Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

      Every donation made will go towards server fees and maintenance costs.

          Lenovo ThinkStation P720 BIOS Request
          by HammyCheesy
          Hello all,

          I'm trying desperately to revive a ThinkStation P720 that I purchased from a seller who claims it suffered a "failed firmware update."

          When given power, the machine turns on, spins up fans, beeps a single time, fans slow down, then a beep code is sounded repeatedly (3 high/short tones, 1 low/long tone).

          Things I have tried:

          1. Reseated all components, pulled everything except for 2 RAM modules (1 per CPU)
          2. Attempted to boot with just a single CPU...

          • I have a CH341A programmer and have successfully created two full backups of my BIOS.
          • I have the ability to use command-line tools on a Linux machine.
          Troubleshooting Steps & Conclusions:
          • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
          • I concluded that the
