    Post the laptop serial number, read the rules please -> https://www.badcaps.net/forum/troubl...before-posting

    What model is your programmer and software version, are you sure the chip is corrupt. If you can read anything from it at all post the backup.

      Sorry. Serial number PW-0844N2. I have the T48 programmer with the latest firmware version and XGpro software. The bios chip is phisicaly damaged due to a bad motherboard intervention. I ordered the 512 mbit IC and now I need to program it.

          Summary of BIOS Whitelist Removal Problem


          Problem:

          Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
          by grimacelord
          Hello there.

          I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.

          History:

          1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.

          I searched for this error online and discovered...

          Lenovo ThinkPad L15 G3 Bios 1 IC conductor track
          by 1g0r
          Hello everyone,

          First, the data in brief:

          Model: ThinkPad L15 G3 21C3-0016GE

          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...
          The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

          Lenovo Thinkpad X1 carbon 11th Gen BIOS problem
          by MaxonDomkrat
          Hi everyone.

          I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto...

          Should I buy a Lenovo Thinkpad E495 with bios password?
          by RMDUiFT
          Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

          I have a few questions:
          • If I would buy this laptop and have
